Customer Ratings & Reviews

These sound amazing!! You will need to download the app and make personalizations to suit your needs. I have created 3 profiles which has allowed me to pick my preferred sound. After you create a profile that customizes to your ears, you have the ability to make additional tweaks in the EQ setting to really enhance these to a whole new level. I bought these primarily for music, but the noise cancellation is very good and I have had no issues with quality of phone calls. They stay in my ears and are comfortable to wear for 2+ hours. Warning: with all the adjustments these things can get very loud without any distortion to the deep bass. Don’t injure your ears, be careful!!

This is probably my tenth set of wireless BT earbuds.  Why, because they keep getting better, and I've always appreciated the Denon sound quality (I have their receivers and wireless speaker).  Denon claims 24h battery life 8h+16h from charging case). I fully charged, and updated my firmware before trying them out.  I had no problem pairing them with my iPhone 15 pro.  I then ran them through Tara Labs Noise burn in overnight (they lasted ~7h 45m), just short of the 8h quoted, and then I recharged them.  I installed the Denon Headphone App. The earbuds were immediately recognized, and my battery level showed 100% on each earbud. The software provides an equalizer (only 5 bands, 400, 1K, 2.2K, 5K & 10K that you can adjust +/-6db; not overwhelming, but adequate), you can save your own curve with your profile. They allow setting up to 3 profiles, the real customization comes from the Adaptive Acoustic Technology, which plays a series of tones/music and then detects how well you hear each frequency, it only takes a minute or so (in a very quiet environment) for these tests to be done. They graphicly show you where they are testing and re-testing. They then show you what areas they believe need emphasis.  I was not surprised to see I need a little mid to low end boost, but that my high end hearing was good. You can then compare your personalised curve on/off. Leaving little doubt how well it works! Then on to the really important part, how do they sound and fit.  I generally move to the next larger rubber earbud surround, but after testing I found the standard set worked just fine for me.  I generally prefer a soft spongy insert for longer listening, which they include in the standard size. And they fit comfortably in my ear canals', they did not feel loose, like they might come out, and the sound seal seemed very good. I had a hard time telling the difference between the foam and the silicon, but I think the form isolated the external sound better. Now to the music, Pink Floyd's masterpiece; DSOTM.  Speak to Me sounded great, the volume level was wonderful, opening up the subtle sounds of the song. I had the  earbuds at 80% volume and that was fine (for now), but knowing they could be drive higher, I did play with the immersion mode at +2/+3, this boosts the low/mid bass, mostly (+2 is nice; +5 provides too much emphasis; your mileage may very). The subtle tones were absolutely superb as the song builds; it had the oomph you could feel, that higher volume brought.  The high notes (treble) in Time were excellent, these earbuds provide a sharp/crisp clear airy high end.  Then Great Gig In the Sky's ethereal voices, wisp around the soundstage (enhanced by the included Spatial Audio) with the bass building as it should have.  Money got me drumming, it sounded so real, the tom-toms had a real kick to them, and it was even better a little louder.  Us and Them was tremendous, it kept me turning my head, like I could tell the different instruments were right in front and around me.  As we ended with Eclipse I felt like the little voices in my head would persist, and there would be more. Then I quickly listened to Kansas Live, with Carry on my Wayward son; the vocals all came from different locations, and I could literally visualise the guitars moving in front of me.  Again the sound stage with live music is much better than I expected from ear buds.  I then moved to Boston's first album; More than a feeling was very crisp, and the bass had real presence with very nice highs.  On Foreplay/Long time the fade in/out fade had great separation it was nearly surreal.  The subtle build up was just as I expected, possibly better.  The bass was nice and deep, a little boomy (I turned the immersion mode down to 2, and it was more to my liking). Here I tried turning the personalization on/off to see how well it worked.  Quite impressive, like having a 2D or 3D soundstage.  The immersion  mode can be overdone, but it's easy to adjust. I tapped the earbuds to advance the song, it worked as I expected.  The touch controls can be programmed as you desire (a nice feature) 1,2,3 taps and double tap and hold, so 4 different options on each earbud.  The software can also control ANC (Adaptive Noise Cancellation), On and Off. Outside I could barely hear my A/C running with it on, and it was noticeable with it off.  A big difference, I imagine they will work great on an airplane.  But I don't think it is as good as a couple other name brands in doing the cancellation.  And I do really like their social mode that lets you hear the external sounds clearly, and mostly mute the music in the earbuds. I'm accustomed to the software including custom sound profile but the Denon customization/personalization does a truly excellent job. The immersion mode is another bonus, the EQ could have more bands and the ANC does a really nice job.  The earbuds are plenty loud with great battery life.  The battery case is a reasonable size with a USB-C connector. All told these tremendous earbuds, they are as close to the best that I've heard (at nearly the same price).  After listening for several hours, I found them very comfortable, I appreciate that they ship with foam and silicone tips so you can get just the right fit.  I just spent a 7 hour day with them in.  I rarely thought about their weight (other than how good they sounded), so I decided to program the social mode into the tap twice "space", as it really comes in handy (when you have to interact with real people).  And I think they look good (better than looking like you have marshmallows or cotton in your ear).  Having an iPhone, I could NOT try AptX lossless delivery (only available to Android users (not Apple), I've used it before and I'm sure it's another plus to these earbuds. Denon is new to earbuds and they have built themselves a real winner.  They are why I keep looking, but I doubt I will stop further research, certainly from trying what their follow on product is.

Denon is really best known for their line of home audio products, designed to give you optimal sound with some of the best receivers available. I went into this with the same expectations, a quality pair of headphones, with amazing sound, minimal audio quality loss, and superb usability. I can honestly say, they didn’t disappoint! In the box, you’ll find the Denon charging case, the two ear buds within, a charging cable, various sizes of tips, and some basic documentation. In order to maximize your use, I’d highly recommend installing the Denon app, which is free in your compatible app store. Pairing with your device is as easy as putting the ear buds on, and following the voice guidance, you’re directed to find them discoverable via Bluetooth. I found the initial pairing process was easy, and the ear buds were immediately recognized and paired with my iPhone in a matter of seconds. Without performing any of the app calibrations, I was pleasantly surprised with the audio quality and bass response. However, once you’ve opened the app, you’ll find that you can customize the audio using a feature which measures the sound in your ears. You’ll hear a variety of tones, some low and some high, that allow the ear buds to calibrate to your hearing to provide the best audio quality available. This took a minute or two, but once it was done, it provided a personalized EQ like setting which really brings the audio to a whole new level of awesome. After I performed the initial calibration, I rarely ever adjusted the audio for any type of content moving forward. I even turned off the EQ built into the settings on my iPhone and relied only on the Denon applied settings for sound. Listening to a variety of content, I was blown away with just how clear the audio was. The Denon’s even provided better sound than my previous earbuds when using noise cancelling. Taking these on a flight, I did notice that most sound was filtered out, and while it’s not as great as earphones that cover the entire ear, they easily outperformed my previous headphones as the go-to for travel. The included case also charges them when not in use, and does an admirable job of keeping them charged for most of the day. Overall, I was pleasantly surprised by the quality of the audio experience and the easy to use app to set everything from taps to holds to control volume, call answering, and play/pause. The bass is probably some of the best I’ve heard from “pro” level ear buds, and is probably the highlight of the audio journey I took wearing these during my travel. The bluetooth connectivity is also excellent, and I noticed I didn’t lose connection at all during use (compared to others I’ve used prior). Denon really delivered with this one, and I’m hopeful you’ll give them a shot over 1st party headphones for your device.

If you are looking for some of the best sounding earbuds on the market today, then be sure to check out the Denon PerL Pro True Wireless earbuds and take the time to fully customize them to your unique hearing profile and they will blow you away. Opening up the box you have a wide array of fitment options that not only include silicon and foam ear tips, a couple of wing attachments, a short USB A to C charging cable, the earbuds, and the charging case with Qi charging ability. Each earbud is very light, and the case is small and light as well. The earbuds fit snugly inside, and magnets help guide them to their charging locations. The case also has three lights to indicate the power status of each earbud and the case itself. I was able to test with phone calls and both ends are met with superior sound and the other person on the phone was impressed with how I sounded. Battery life has been fantastic as well, they are rated for 8 hours and 24 hours with the case providing additional juice. I found that my earbuds were very close to these numbers. During my initial testing, I did a lot of trial and error to find my perfect combo of ear tips and wing attachments, and it is nice that a good variety is included with these. These fit snug and comfortable in my ear and after you settle on the perfect fitment, they don’t feel like they are going to fall out of your ears, and I never felt fatigue with having them in my ears. Connecting to my phone was easy and I was also able to connect to my PC at the same time, so they support muti-point connections which is another big plus for these. Switching between music on my Pc and a phone call was simple and seamless. Tap control controls are available and customizable via the Denon app. Single, double, triple and a double tap and hold for each side. You can set any of these up with how you want them such as a single tap on the right for volume up, double tap on the left for prev track, etc. When you first launch the app, it walks you through personalizing the earbuds for how your ears are and how you actually hear things. After a few minutes, it will generate a series of tones (using adaptive acoustic technology) and configure things for you. I recommend doing this a few times and create a few different profiles to try things out. It’s a neat process and it seems to really make it sound better for your ears. I have had quite a few sets of earbuds over the years and these are by far the best sounding, best fitting, and best app that I have used.

For starters, these earbuds are as big as they look on the out facing side. There’s nothing “discrete” about them, which isn’t a negative! One of my complaints with other brands is that they were on the verge of being too small for any real functionality, plus I often dropped them. The actual tip that goes in the ear is a standard size and is extremely comfortable. Most units come with 3 different size ear tips, but Denon includes 4 different sizes ranging XS to L and a foam set. Also included are two different sized wing attachments for a secure fit. The stated battery life which seems to be spot on is 8 hours, with an extra 24 hours available via the storage case which charges via the included USB-C cable and can also charge wirelessly. Two devices can be connected at once, and either earbud will work independently if you like to switch to extend battery life. The earbuds are marketed as sweat resistant so should be good for most workouts that don’t involve actual water. There is an accompanying app, but you must have both earbuds in to use it. The app allows for multiple user profiles, which is important once you personalize the sound response. When you start the app, it will do a test to determine whether you have selected the right ear tips for a good fit. It will play sound and picks up the feedback via the 8 included microphones to determine the fit. Once done it then does a hearing test to measure the range you can hear in each ear and set the personalized audio profile including the EQ settings accordingly. But there’s also the option for manual controls. The app allows you to customize the “tap” controls on the earbuds, which include the standard expected options. You can also control the Adaptive noise cancelling, immersive base and a social mode that allows you to hear outside sounds for office or other environments where needed. I was very impressed with the additional “immersive base” option! It made it sound like you were in the room with the sound source! The only thing I would change about these earbuds is related to the case design. Given how flat the tops are, how flush they fit in the case and the power of the magnets holding them in…I wish the indent to remove them was a bit deeper.

Let's get right to it. Denon is well known for making very premium speakers. Great sound ands coordination between the family with pairing. Now you have to know how excited I was to get the opportunity to get my hands on these PerL Prp true wireless buds. I was a little concerned about the sweat resistance. But good news. These are IP X4 rated. This allows me to get caught in the rain if I'm out on a morning cardio session and it starts raining along the way. Inside the box you'll be greeted with a nice sturdy case ( housing the earbuds) a short charging cable( Type C) some ear wing tips for a more solid fit when you're getter really active and a few different sized gummies to proprely fit your lobe size. The small charging cable isn't such a deal-breaker here. Because the case can also be charged wirelessly. I love that feature in a pair of bluetooth. At first glance, these earbuds look huge. But after taking them out and having a good look, they are quite fashionable. And aren't as big as they look. Very comfortable to wear while running on the treadmill and pretty solidly in place while I lift heavy. Yes. My lobes flex when I lift.The Denon app is easy to use and you can set up to 3 sound profiles in it for defferent occasions. The ANC is really good I feel immersed in my music when they're in.These things will talk to you also. So you'll have a new friend in your head. Lol! Collaborating them allows the earbuds to lear how you hear your music so you can the best sound per bud. That's a lot in this package. I love these things. They are my new favorite true wireless buds. With up to 24 hours of listening in the box and 8 hours per charge, you can't go wrong here. Get em.

One of the more unique aspects of these headphones is the companion app, where during setup, you are encouraged to create a unique sound profile. While there are a lot of apps that let you create a sound profile, tweaking individual eq levels, or selecting from various presets, this is the first time I’ve experienced an app at least claim to measure your ear’s sensitivity to sound, and automatically alter the output based on those measurements. This works by playing a series of tones in each of your ears, and I presume measuring in some way, the way the sound waves bounce back to the headphones. The before and after of using the auto calibration based on your specific ears is a dramatically improved experience. The reason it feels a bit gimmicky is the unadjusted audio is just bad. It throws out all of the eq headphones normally due to optimize sound, so while it’s a huge improvement over the default state, it’s not a huge improvement over other in-ear headphones that attempt to optimize audio by default. All that said, these earbuds do sound great. I’ve been happy with everything I’ve used them for, including in noisy environments. The passthrough is pretty good but not perfect. Hearing clarity is noticeably reduced when using passthrough. It’s fine for briefly hearing someone, but if someone is soft spoken, or you want to have a back and forth without repeatedly saying “what?”, you’ll probably want to remove them. Overall, these headphones fit securely and felt comfortable, in addition to sounding great. I’d give them a 4.5/5 overall.

I received the Denon PerL Pro True Wireless Adaptive Active Noise Cancelling In-Ear Earbuds in Black. The earbuds make a good first impression. Disc-like endcaps look classy, with a matte black finish. Basic setup is also relatively simple thanks to the Denon app. The buds were a little uncomfortable in my ear over a period of time, as they are quite large. That being said, being large does provide a good amount of space for the touch controls, which proved both responsive and comprehensive. The Denon PerL Pro offer a uniquely tailored listening experience, it measures your hearing, then tailor a sound profile based on your ears' basic design and frequency sensitivities that adapt and change over time, the hearing test results will not disappoint you. Has Bluetooth 5.3, USB-C, Dirac Virtuo, aptX Lossless, aptX Adaptive, Masimo Adaptive Acoustic technology, wireless charging, immersive and spatial audio modes, designed to create a 3D effect by virtualizing stereo sound. The battery life has been pretty good, you're getting a perfectly acceptable eight-hour battery in the buds, with an extra 24 in the case, wireless charging, IPX4 sweat resistance. Overall, these are great earbuds, the sound is excellent, very easy to use and customize in the app.

Pros Excellent sound quality after tuning Tunes audio to the way you hear EQ in addition to custom tuning Smooth, tight bass Clean highs without harshness Comfortable for extended usage Light for size Ear wings keep earbuds secure Long range Bluetooth Multipoint Bluetooth Easy to use controls Customizable controls Customizable auto-pause behavior Excellent battery life Good microphone Good ANC USB and Qi Charging aptX lossless audio on supported phones Cons Most popular phones don’t support aptX Social mode causes your voice to sound muffled Using controls creates thump sound on eardrum Might be too large for some Earbuds hard to remove from case Volume too limited on social mode Earbuds never seem to be fully charged and one charges differently App keeps asking to agree to legal agreements on every launch App requires you to opt into marketing App requires too much personal information for headphones The Denon Perl Pros are earbuds are larger than most earbuds but thankfully they are designed to be low profile. Included in the box are several ear tips, including one pair of foam, and two sets of ear wings that help secure the earbuds in your ears. While the overall diameter is large, they are very low profile. The outer disk on each earbud is a touchpad which has four options for control from a single tap up to four taps. While it has default options for single and double tap all controls can be customized. Multipoint Bluetooth is available for up to two devices simultaneously. The behavior for how audio is switched is customizable. Auto pause behavior is also customizable where you can choose to pause when one or both earbuds is removed or not to auto pause at all. Setup 9/10 While you can pair them via Bluetooth and begin using them straight away you won’t be able to customize the audio or settings without going through the Denon Headphones app. Unfortunately, the app requires registration to begin. Beyond that you are required to provide your email, name, and age as well as opt into marketing emails. It will not continue if you do not agree to these. During setup the earbuds provide audio prompts as they guide you through tuning the earbuds to your ears. While the initial voice is pleasant, you cannot change the volume so if you have decent hearing, you might find the first stage of the setup painful as it plays ear piercing sounds. After the tuning is complete you can compare the earbuds with and without your personalized profile. While the customized sound does sound better, it almost seems like Denon artificially sets the default EQ poorly to make your customized sound seem even better than it already is. After custom tuning you can also try out social mode, spatial mode, and immersion mode. Social mode and spatial audio are only on/off. Immersion is customizable but essentially adds or removes bass. After creating your custom tune, you can still customize the EQ if you prefer to color the sound beyond what your ears hear best. The earbuds can store multiple tuning profiles for different users and the settings seems to be stored directly on the earbuds. This way if you would like to share them with a family member and they have their own Denon account they can still access their custom profile on the earbuds. You can also switch between them just to see how each person hears different. Usage 9/10 The case holds the earbuds in with strong magnets. The earbuds are unlikely to fall out of the case accidentally. In fact, you might find removing them from the case is a bit harder than it needs to be as they sit down into the case without any real way to put your finger underneath them or grip them from above to remove them. There is just a tiny gap where you can jamb your finger to wedge them out. It would have been ice if Denon included an area that would easily fit your finger to get underneath or even had the earbuds sit a little higher in the base instead of flush. Putting them in your ears is simple once you get the hang of it. You push them in and then turn to lock them in place. For some you might need to gently pull back on your earlobe while turning to get a better lock of the ear wing at the back of your year. Once you have them in, they feel very comfortable. Since they are low profile, they don’t put a lot of pressure on your ear canal and the ear wing keeps them from wiggling around. They are also light enough to not feel distracting. This is the longest I have ever been able to wear a pair of earbuds without feeling pain or any discomfort. Controls are simple and easy using anywhere from 1 to 4 taps on either the left or right earbud. The areas you tap are very sensitive and so far, haven’t been affected by sweat. There are two downsides for the controls. First is when you tap them, it creates a loud thump sound on your eardrum. Second is that successive taps are registered slowly meaning you can’t do a quick double tap to change songs. Music Quality 10/10 Music quality is where these earbuds shine. After tuning, the earbuds provide a richness of sound that sounds closer to what you would get with a large home sound system. Highs are clean and clear with no discernable harshness. Mid tones are smooth and rich. The bass is clean and tight but also can hit hard if you want it to. In fact, on some songs with Immersion set to maximum the bass gave a slight illusion that you were feeling it and not just hearing it almost like sub audible bass does on a good home system. Thankfully it is fully adjustable so regardless of your preference for bass, or lack thereof, you won’t feel left out. With acoustic music you can hear more detail in the instruments and vocals sound crisp and clear with subtle details such as breath control being audible. The Spatial audio effect gives a slight echo effect and gives more of a sense of depth. On some songs there is a sense of a soundstage which is unexpected from earbuds. Calls and Social Mode 6/10 While listening to the music is a top tier experience, social mode and call quality is not quite as high end. When social mode is activated, maximum volume is limited to approximately 60% of the normal maximum meaning your music will sound too quiet. If you turn social mode back off, the volume will jump up substantially. For example, if you have them at a louder volume when in social mode and turn it off you may find the volume quickly jumps to excessively loud. It seems like Denon was attempting to make it easier to hear outside sounds in social mode by reducing volume but it would be better if the volume stayed at a single setpoint so there would be no abrupt changes. Furthermore, in social mode the microphones do a decent job of passing through outside sounds, but they do sound slightly compressed. Where the social mode falls apart is when you speak. While your high tones are passed through correctly, certain tones you can hear resonate through your skull. It’s not unlike when you try to talk with earplugs in and your voice drones in your head. Other earbuds have a way to compensate for this and hopefully Denon will be able to improve this with a future firmware update. As it stands now, speaking in social mode is subpar. The same microphones are used for calls and show some similar weak points. When speaking to others they reported that it sounded clear but hollow with voices sounding distant. However, speakers did report that ambient sounds were less prominent compared to speech making speech easier to hear overall. ANC 8/10 Active Noise Cancelling does a respectable job of blocking out unwanted sounds. The effect is further improved by the fact that the earbuds seal very well inside the ear canal blocking out sounds. While not the strongest ANC ever used, it has been able to block out the sound of a fan, water running, car traffic, and even most of the sound of a helicopter passing overhead at a low altitude. While it doesn’t completely block out other voices, it does greatly reduce them to where if you worked in a busy environment with other people, it would be easy to ignore background conversations but still be able to tell if someone is trying to speak with you. Between the natural sound blocking and ANC the Perl Pros work very good for helping to block out unwanted sounds to focus. Battery 10/10 While Denon focuses on sound quality being the standout feature of the Perl Pro, the battery life is also a standout feature. The longest stretch of continuous usage so far was over 3 hours at a reasonable volume. After removing the earbuds there was no discomfort in the ear and checking the battery both earbuds were sitting at 80%. There is also a Low Power mode that can help improve battery life further. The one strange thing observed was recharging in the case. Since the first usage, the earbuds never seem to have the same battery remaining out of the case. One earbud can be at 100% while the other is at 70%. It might be something intentional with battery charging or it might be the two small charge pins didn’t fully line up while placing back in the case. So far both earbuds have had ample battery life for each session, but it is unclear why this is happening. Final Thoughts The Denon Perl Pros are a good overall set of earbuds with a solid feature set. While others might beat them in certain features, they are hard to beat when it comes to music quality. If you want a quality set of earbuds that value music quality above all else, the Denon Perl Pros are a solid offering.

I’m usually a pretty simple guy and don’t usually splurge on higher end items. I don’t consider myself an Audiophile. I have a set of original AirPods that are my go-to headphones and I thought I splurged when I got them. These Denon - PerL Pro Headphones make those headphones sound bland. Out of the box, I thought they sounded good but can’t say I was really impressed. The magic happens when you install the app. The app walks you through setting things up including changing the ear tips. Once you get the proper tips in place, and the app actually checks that they are the correct tips, it with run a program to create a personalized ear profile. It will use this profile to adjust the music so that you get the best experience for your ears. I know this sounds like voodoo but it does work. The difference between the Default mode and the Personalised (yes, spelled with an ‘s’ in the app) mode is night and day. When Personalised is selected, you can really hear all the different instruments clearly. There is a separation that I just haven’t heard on other headphones. The app does have a fairly simple EQ with 5 sliders to adjust the sound. I didn’t find any improvement in the sound using this after my profile was created. It also has an immersion mode that does increase the fullness in sound. The lowest immersion setting sounds flat to me and the highest is over-boosted. I bumped it up 2 clicks and I’m very happy. The App also has buttons for a Social Mode and a Spatial Audio Mode. Turning off Spatial Audio blended the sounds so the instruments lost much of the separation I was initially so impressed with. This will stay on in my app. Social mode reduces the amount of noise cancellation and passes outside sounds into the headphones so you can hear sounds around you. I tried this in a room with a TV on and can’t say I was impressed with the results. While I could hear the TV somewhat, it was still quite muffled and I couldn’t really make out what was being said. The tap gestures on the headphones are also customizable in the app. I don’t usually use this feature. Out of the box, tapping the Right earphone will pause the music. Tapping the Left one will toggle the Social Mode. Double tapping the Left side opens Siri on my iPhone. Double tapping the Right side will skip to the next track if you are listening to a playlist. The doesn’t do anything on the XM app I use for streaming. My biggest issue with the headphones was getting them to fit in my ears. None of the standard rubber tips would hold the headphones in my ears. After spending almost 30 minutes trying different combinations, I finally just went with the foam tips. These were the only tips that the app said sealed enough to perform the profile tests. Now, these tips work but the headphones still feel a little lose and you feel them after a few hours. These headphones are on the larger side. I would not use these doing any kind of exercising (especially jogging or bike riding) or physical work. They might be OK for walking but they are definitely are best for working at a desk or just relaxing. As for battery life, I’ve used them for up to 4 hours at a time with no issues. After an hour of use, they were down to 90% battery life in the app’s battery meter. After 4 hours I saw 50%. I can believe they last 8 hours on a charge. These Denon - PerL Pro Headphones are pretty amazing in terms of how they sound. They are certainly not perfect but the issues I have with them are not worth deducting a full star. All in all, I am quite impressed with these and would recommend them to friends. I would just inform them of the possible ear fitment issues.

The Denon PerL Pro True Wireless Adaptive Active Noise Canceling In-Ear Earbuds pack in some of the coolest sound technology I have seen and heard to date. I must say, I am thoroughly impressed. The star of this product is the Adaptive Acoustic Technology that makes a personalized sound profile that you set up in the Denon smart Phone App.The app makes you go through a fit test, to make sure there is a proper seal. It will then go through several sound tests to determine which frequencies that your ears can hear and which ones they are sensitive too. After the sound test is complete you can choose from the default settings or your new personalized settings, and boy does the personalized settings make a huge difference to the quality of the sound and I highly recommend going with this setting. The sound quality of these earbuds is equally remarkable. The audio is clear, crisp, and well-balanced, delivering deep bass, rich mids, and sparkling highs. Whether I was listening to classical music, rock, hip-hop, or podcasts, the PerL Pro earbuds handled every genre with finesse. I could hear every instrument and vocal nuance, immersing myself in the music. In the app there is an EQ slider where you can adjust these settings to your liking. The noise cancellation feature is pretty good for earbuds, where when listening to music or to podcasts, the background noise will be blocked out. This is not the case when paused you will still be able to hear some things such as fans and A/C in the background. This can be easily activated by assigning the touch button to either the right or left earbud or by clicking the icon in the Denon app. In the app you can also select if you want spatial audio on or off, where with this feature the sound will track with the movement of your head. This is only available with certain 3rd party streaming apps who offer it. The earbud can always be set to this and will automatically apply it when available. One of the under the radar features that really stood out to me, is the ability to be paired to Two different devices at once via bluetooth. This is huge for me since going back to work in the office because I can be listening to a podcast on my phone and take a virtual meeting on my laptop and it will automatically connect to my laptop. And not having to constantly unpair and repair bluetooth. This alone could be a reason to get these earbuds. In terms of comfort, the PerL Pro earbuds fit snugly in my ears without having to worry about them falling out of my ears. I was looking forward to using the foam ear tips that came with the earbuds because those are supposed to give a more tight seal, which it did but for my ears they were not as comfortable as the standard ones. The touch controls can be a little spotty and trying to assign a triple tap option doesn't always respond the first attempt, that or I haven't gotten the rhythm of the taps, so have just unassigned 3 taps for the time being. The battery life of these earbuds is impressive as well. I was able to enjoy several hours of music playback on a single charge, and the charging case provided additional power for on-the-go use. The quick charge feature came in handy when I was in a hurry, and the case is also able to be charged on a wireless charger. My only real nitpick from these earbuds is that after like 4-5 hours of continuous usage, my ears did start to feel a little uncomfortable and could feel a little indention in my ear from the wing holder on the buds when I took them off. But I guess that's a small tradeoff for great sound quality. Overall, the Denon PerL Pro True Wireless Adaptive Active Noise Canceling In-Ear Earbuds are a true marvel in earbud technology. With the good noise cancellation, the superb sound quality with the use of Adaptive Acoustic Technology. Denon has set a new standard for what wireless earbuds can do.

This is my first pair of wireless earbuds from Denon, though it’s a brand I’m familiar with as I have one of their soundbars for my TV. The earbuds come in a pocket-size battery case that charges via USB-C or Qi wireless charging. An 8” USB-A to USB-C cable is included as well as 4 sets of silicone ear tips, large, medium (pre-installed), small, and x-small, a set of medium-size memory foam ear tips, and two pairs of ear wing stabilizers, medium and large. Don’t be afraid to mix and match the wings and tips, as not everyone’s ears will be symmetrical; this helps ensure that you’ll find a good fit for your ears and create a good seal while still being comfortable to wear for extended periods of time. I personally don’t love having things in my ear canals, but found that the unique oblong shape of the ear tips on these sat more comfortably in my ears over longer listening sessions than the typical round shape. While I’ve owned dozens of Bluetooth earbuds over the years, none of them have delivered a customized listening experience like the Denon PerL Pro (a mashup of Personalized Listening). The PerL Pro uses Masimo Adaptive Acoustic Technology, formerly Nura, to tailor a unique sound profile mapped to your ears based on how they perceive sound. In order to take advantage of this technology, you’ll need to download and install the Denon Headphones smart phone app and complete a short calibration in which you’ll hear a series of tones; you won’t need to submit any responses like an audiologist’s hearing test, and it takes just a couple minutes. Once completed, you’ll get a visualized “map” of your ears’ sensitivity and deficit towards different frequencies. You can save up to 3 profiles if you have multiple users, though you can only swap between them using the app. If you want further EQ customization (with or without personalization), use the app’s ProEQ to adjust 5 bands of frequencies. The difference between the unmodified and personalized profile is quite noticeable. For me, music sounded less flat with a wider and deeper sound stage. My profile indicates that I’m extra sensitive to higher frequencies, so my profile reduces the levels in these ranges which took the harsh edge off sibilance in voices and sizzles in cymbals and hi-hats. It also boosted the bass as there’s where I showed the most deficit, making it sound fuller and better supported in the lower registers. The best way to describe it is like hearing the difference between watching a concert on TV and being there in person. These earphones use Bluetooth 5.3 with multipoint connection, so you can pair them with up to two source devices simultaneously and quickly switch between the two by initiating playback. I also found these perfectly suitable for watching videos and movies as there was no perceivable audio lag or delay. One of the main features that Denon advertises is the “uncompressed” CD-quality sound delivered by Qualcomm’s aptX Lossless codec, but in order to benefit from it, you’ll need a compatible transmitting device; a difficult feat considering there just aren’t that many devices that currently support it (my flagship Android phone does not, nor do iPhones). It’s much more likely that you’ll be utilizing one of the other supported lossy codecs: aptX Adaptive, aptX Classic, AAC, or SBC. If you can’t experience the full impact of lossless audio at a 1,200kbps bit rate yet, with an aptX Adaptive capable device you’ll still be able to playback audio with up to 24-bit depth, 48Hz sample rate, and 420kbps bit rate, and it’s always nice to have a bit of future-proofing too. The earbuds have adaptive noise-cancellation that do a decent job at silencing the outside world with its eight microphones, enveloping you in a veritable sound bubble. Though its parameters are not adjustable or customizable, ANC can be toggled off. The mics also do double duty for capturing clear super-wideband (32kHz) voice calls. On the other hand, if you would like pass-through audio so you can hear people around you talking, enable “social mode,” and you’ll be able to listen to your environment along with your music without taking your earbuds out. Immersion mode is basically a shortcut to increase/decrease bass EQ in the low and low-mid frequencies by up to 3 levels that can be toggled on and off. Virtualized spatial audio from Dirac Virtuo, when enabled, creates a more three-dimensional sounding environment via stereo upmixing, however, depending on what you’re listening to, you may not perceive a huge change other than sounding slightly more resonant. All of the modes and playback controls, including play/pause and volume, can be programmed to touch actions, 4 on each earpiece with single, double, and triple taps as well as tap and hold. I like that the large profile of the earpiece makes executing these easier, but I did find that double and triple taps have to be quite quick, otherwise they will register as a series of single taps. The earbuds are also lightly weather and sweat resistant but only to IPX4 which means they can get wet but not be submerged. The PerL Pros have 8 hours of battery life on a full charge and dropping them in the case can top them up with an hour’s worth of runtime in just 5 minutes, up to 24 hours of additional use. The case fully charges in 1 hour and can simply be placed on a wireless charging pad to charge. On the front, there are 3 embedded color-coded LEDs (red, yellow, green) that turn on for several seconds when the earbuds are removed or replaced. The middle one represents the battery life of the case, and the left and right LEDs of their ear pieces respectively. Overall, the PerL Pros provide an immensely satisfying personalized listening experience, even when using lossy codecs. The audio produced by the 10mm dynamic drivers output more than enough sound for safe listening with low-distortion, sparkling trebles, fully rounded out bass, and balanced midranges. While not as immersive or directional as a true surround sound system, spatial audio places you at the center of a natural and realistic sounding 3D sound stage with depth, accuracy, and precision.

The Denon Perl Pro is a thing of beauty. This true wireless earbud offers a premium feel, fit, and sound. The sound quality and clarity in this pair of Denon Perl Pro earbuds is individualized to fit the users specifications based on ear shape and hearing ability. These utilize a technology called Masimo AAT and it is going to be unique to each person's ear. When these earbuds are partnered up with the Denon app on my iOS device, they allow me to go through a customization process. This process and sound test measures my hearing and based on feedback the Perl Pro is adjusting the profile to each ear independently. The audio music I have been streaming and listening to sounds very crisp and precise to my ears. My wife will listen to my profile and not have the same experience, so we created her own profile within the app. There is a unique Denon signature sound that is delivered to the user. The highlights of these headphones are the customizable sound profile, but there are many other features as one would expect in this price point. Ambient sound settings to be aware of personal surroundings and to have a clear conversation with someone nearby. The Qi charging case allows for full day power between charging. There is Adaptive Active Noise Canceling which seems to work fairly well, but is not the best available. If you don't like the customizable sound profile the app builds for you, there is the option to create your own EQ settings within the app. The touch interface on both left and right earbuds act independently and can be customized to make it suitable for your preference. The sound quality offers a lossless and spatial audio as well that gives more immersion into the audio you're listening to. Another great feature for anyone that likes to be outdoors or working out, is that these are weather and sweat resistant. Using these headphones for phone calls sounds clear when listening and the audio when speaking is clear and audible. Multipoint connectivity comes in very handy throughout my work day while I have these earbuds paired to my iPhone and my Dell laptop. I can easily jump from listening to music on my phone to using my earbuds for a YouTube video on my laptop. Overall I think these earbuds are phenomenal for the sound quality. I would say the ANC capability is just ok, but could be better hopefully with software upgrades. The multiple tips that are provided are helpful in getting the best fit and comfort in each user's ears. I like the looks and design, and I'm loving the sound.

I am an audiophile and have been for over 20 years; I typically focus on large-scale speaker setups (Currently have 5 Setups, including a custom-made horn-based one) due to no over-the-ear or in-ear headphones sounding even close. Well, that is no longer the case. I have used the technology in these earbuds for years, ever since I received a prototype unit of the Nuraphones many years ago from the company that was purchased by Denon to make these earbuds. Adaptive hearing technology has always been amazing and allows you to hear music in a neutral format, but it was far from an audiophile, and all of the other products released after the original were subpar and had many technical issues. Now that these have been released under the Denon Brand and have their support, I have not seen any significant bugs, just sweet, sweet sound. The simulated sound stage is amazing for IEM; the adaptive hearing technology has impressed everyone who has put them on, the battery life is fantastic, the clarity of the music is great, the music has great life to it, and BEST OF ALL THE ANC (Noise Canceling) IS EXTREME! The Noise Canceling has to be the best-unexpected feature as it makes you feel like you are sitting in a listening room even while you walk your dog on a busy street; no issues with wind, no odd noises, and it truly is perfect enough that your wife could be in the same room yelling to get your attention and you can't hear a word of it (dangerous do not try at home!) LONG STORY SHORT! THEY ARE WORTH EVERY PENNY! BUY THEM NOW! IF YOU TRULY LOVE MUSIC THESE ARE THE ONES FOR YOU! (If you have any questions about them, ask away)

I was skeptical about them being better than the current mainstream buds, but they are on another level. Daily practicality and intuitive features have shown otherwise. Once the sound test is done be prepared to be blown away. You will want to listen to all of your old music once again. Its like going from basic tv to 4k tv in sound. May not have as many gimmicks as competitors but it knocks the sound, hold, and comfort out of the park! My new favorites.

I was so excited to get these and try them out; afterall, I've used Denon / Marantz receivers and speakers for over a decade with success. Unfortunately, the PerL Pro's are terrible in terms of fitting them to your ears, setting them up in the app, and definitely in terms of performance. Denon is very late to market with these truly-wireless earbuds, so time should have been taken to get it RFT (Right First Time). These are neither fit to be on the market nor worthy of the Denon name. Too little, too late. Open up the box to get the different size tips and pull out the plastic bag they were in (see pic). At this price point, it's a miss. Among many other misses. The silicone tips have circular holes to fit over the tips of the buds. Unfortunately the bud tips are oval. Conceptually, it's easy to pinch the silicone tips and place them over the oval tips of the buds but it isn't easy when there is little silicone to grasp, and I need to push them over the lip of the bud tip to stay in place...and they don't, even when you think you have it, the the silicone tip flies 3 feet away. There are also 2-3 different sizes of wings for a custom fit. The wings do nothing due to poor fit; I'm not certain what ears they are made for. You are supposed to hold the earbuds, put them in, and rotate them, but when you rotate, it doesn't 'catch' anything, and you end up starting/stopping your music five times. After an hour of trying all combinations, nothing worked to acceptably seal my ear with the bud. Which is in turn unfortunate, because a good seal is needed during earbud settup, as the app / earbuds 'map' your ear canal / hearing; see the pictures. The error in the pic about poor seal happened a few times, which will cause anyone's blood to boil, knowing that the mapping of ear canal / hearing is like 1-2 minutes long. To be able to finish settup and listen to music, I pushed the earbuds into my ears to make a seal. That colored circular pink/purple 'mapping' looks fancy, but it is meaningless, as a description of colors and mapping is not given. Regarding mapping, you can select 'Default' or 'Personalized'. By all means go through the mapping, because the 'Default' setting results in a 'tinny' sound with no feeling in the music. Everytime I put them away and re-connected them, I had to go through a 20 second search for the earbuds, and many times, I needed to go into BT settings and select them, to get them to re-connect. You finally get them fitted, set up, connected, and mapped, at which point any positive experience was totally over for me. That was solidified when I listened to music...vocals and especially base were terrible. Nothing but popping and crackling. I understand about the size of the drivers, but several competitors can handle base, one at about half the cost of the Denon PerL Pro's. If the earbuds produced impeccable sound, it barely justifies the settup and mapping process. So these are a total Fail for Denon. The charging is fast via USB Type-C. But the case is poorly designed. The case is relatively small, and the earbuds are held in by a magnet. However, the earbuds are impossible to get out of the case because the magnets are strong and you need a screwdriver of long nail to place into the compartment to get them out.

These earbuds are really good. I love the build quality. The sound is awesome. I have no issues with the battery life or the connectivity either. I just wish it were easier to change the ear tips (for correct sizing).

Excellent sound quality but keeps falling out of my left ear. No issues with the right bud. Tried all combinations of inserts. Overall would recommend.

These earbuds are fantastic with adjusting music that suits your ears, awesome sound quality, and a good balance sound profile. They fit securely in my ears although it hurt to wear they on the first day. But, that goes away after wearing them for a few days. Good for vocals, bass, orchestra, rock, and jazz. These headphones can get very loud if you want so be careful.

Awesome earbuds! Definitely worth the price tag, won’t regret it
