Sennheiser - ACCENTUM Open Wireless Earbuds - In Ear Buds with Open Design, Dynamic Sound and Bluetooth 5.3 - Black

TLDR: Tiny, fit in ear, rechargeable in battery equipped case, good sounding, open design so safer to use when running, walking, biking or in public. Great for phone use, resistant to water, not over-priced, 28 hrs per charge, charges up in 1 hour. Matte finish is good for looking good & grip. These are packaged in a small paper-based box with a minimum of plastic which as we know eventually ends up as plastic waste in our water and food supply. You will need to charge them first; it takes about an hour to fully charge them using a common USB-C charger adapter and the included cable or just plug in any USB-C phone charging cable you probably have plugged into a handy outlet at home. BTW, the charger case LED glows green when fully charged from a pale yellow. To connect a new Bluetooth device, you need to tap/hold both buds at the same time. It shows that and other functions on the strictly pictorial small foldout pamphlet that is packed with these devices. Bluetooth pairing mode commences instantly when the charging case is opened These high-quality earphones are very light and comfortable. They are so light you will forget they are in your ears after a bit of time. They connect to Bluetooth really fast, which is not the case with some other brand name pricey devices. The ability to switch between other devices (multi-point) is also very good. When removed from the ears the sound stream is paused. Nice! The touch gestures to control them work fine. I use them with my laptop and carry them in my backpack laptop bag since they literally add almost no weight to my bag. Officially they weigh about 4 ounces with the charger case. As of this time there is no companion app. BTW, the Sennheiser Smart Control app on Google Play does not include these models as applicable. That may change in the future but honestly, the music quality from these Sennheisers is great as it is out of the box. They are semi-open which means you are not blocked from outside sounds and therefore it is safer to use while enjoying news, music or phone calls outside among the public. Using these one realizes the sound is very clear and the lows, mids, and highs are all there and produced nicely. Using these while listening to familiar music I realized I could distinguish some lyrics and some music notes better than I had ever detected before. Even the bass guitar tones are very pronounced and deep down low depending on what music you play. I used them on a few phone calls and the built-on microphone quality is OK. Others did not say I sounded bad. Do they stay in my ears? They do but be careful when using them on more energetic activities such as running or playing tennis or other sports. I have seen the famous white ones falling into a hot tub since the user wanted to wear them there. None of the in-ear earphones are spill proof. These Sennheiser Accentum Opens sound good, last long and are a sure deal at a decent price.

For outdoor exercise and at work, I like to wear open-ear headphones to keep track of my surroundings and not feel isolated. As the name implies, The Sennheiser Accentum Open earbuds are open-ear earbuds that prioritize situational awareness over immersive sound. During the past few days, I took them for a spin in both environments to see if they would win me over. First, I like the simplicity of the set-up; no app needed, just Bluetooth connection.They can be connected to up to 8 different devices, and simultaneously to 2 devices; I tried it with my tablet and cell phone connected at the same time, and changing from one to the other was seamless. The connectivity is solid even over 25 feet. The stemmed design of the Sennheiser Accentum Open makes it easy to place the earbuds over your ear canal without pressure. Each stem houses a responsive control panel with simple commands to your audio device by either tapping or holding. One feature I like is the smart pause when one earbud is removed. They are light and well built with nice little details like the Sennheiser logo imprinted on each stem. The sound itself is very good as expected from Sennheiser. It is clear and detached and a step above my other open-ear headphones that are no slouches either. They have enough power to be enjoyed in a fairly noisy environment. As expected from an open-ear design, the bass is not a priority but is still discretely noticeable. Those earbuds go on forever by the way. Sennheiser claims up to 28 hours of battery and I won’t dispute it. I wear them at work for hours, and they go back to their charging case at the end of the day with plenty of charge left. Phone calls are clear with receptive controls. Those lightweight earbuds are comfortable to wear all day, however my main issue is their small size. I have a rather large ear canal and they won’t stay put for a long period. Sitting at my desk at work, they stick to my ears and feel very comfortable. The pressure is minimal and barely noticeable. However, in several instances while eating, the movements of my lower jaw would loosen them and I would need to readjust them. My experience outdoors while cycling didn’t go as planned as one earbud fell off and I almost lost it. In my case, due to the small size of the earbuds and my larger ear canal, I have refrained from wearing them for outdoor activities. Despite not fitting me perfectly, Sennheiser made a quality open-ear device with the Accentum Open earbuds. I know many other users won’t have the same issue, but it performs very well in terms of sound quality, and its simplicity makes it an easy choice for those looking for an open-ear design, where staying tuned into the environment is more important than isolated pure sound fidelity.

I've really been putting these earbuds to the test. If you're wondering what they're actually like to use, let me share my honest thoughts. Right from the moment I opened the box, they felt high-end. The all-black design is subtle yet super sleek no flashy logos or odd shapes, just a clean, modern vibe. But what really impressed me was how comfortable they are. Once I put them in, they felt so light and natural, almost like I wasn't wearing anything at all. I had them in for a solid three hours, and honestly, I barely noticed they were there. That's a big win for long listening sessions. Now, let’s talk about the sound. This is where the "open" design really shines, and it’s a total game-changer. As soon as I hit play, I was amazed by how spacious everything sounded. It’s not just sound hitting your ears; it feels like the music wraps around you. I played some Michael Jackson, and I could almost pinpoint where each instrument was located. The separation is fantastic—vocals are clear and centered, the drums have this lovely natural decay, and the guitars just sing. I'm also a huge fan of acoustic music, and these earbuds really excel with it. Every strum of a guitar, every soft breath from a singer, it’s all there, crystal clear. The bass is present and well-defined, not overpowering or booming, which I really appreciate. It’s more about texture and detail than just a heavy thump. The highs are crisp without being harsh, and the mids are rich and full. It creates a beautifully balanced sound that lets the music breathe. Now, let’s be honest about the open design. Sure, they sound incredible, but that openness means sound can leak out, and outside noise can sneak in. I tried using them while my partner was watching TV, and I could definitely hear the show. If you’re in a quiet office, your coworkers will probably catch a glimpse of your tunes, too. So, these are definitely best for your personal listening space—your cozy living room, a dedicated listening area, or maybe a chill home office where you won’t disturb anyone. These earbuds aren’t meant for your daily commute or the hustle and bustle of busy cafes, and that’s perfectly okay because in the right setting, they work wonders. Connecting them was a piece of cake, just a standard Bluetooth setup, no hassle at all. The controls on the earbuds are super intuitive, making it easy to adjust the volume, skip tracks, and take calls without any awkward fumbling. The battery life has been impressive; I find myself charging them far less often than I anticipated, which is always a nice surprise. So, are they right for you? After spending some quality time with them, I can confidently say these earbuds are fantastic for a particular kind of listener. If you value a sound experience that’s incredibly natural, spacious, and detailed, and you usually listen in a quiet environment, you’re going to adore these. They’re comfortable enough for hours of use, they look stylish, and most importantly, they make your music feel truly alive. If you’re ready to dive into the open-ear experience, these are definitely worth a look.

Sennheiser now has a set of open ear buds that are oriented for those who are exercise/sports enthusiasts. The open ear design helps to hear sounds around you, but they do not have noise canceling due to the open design. If you are running track, in the gym, or walk/bike along low traffic roads, etc., you may like the open design. Charge Case The charge case is small enough to fit easily in my pocket. The slots in side make it easy to insert and remove the ear buts. The charge case will charge the ear buds each time you insert them and can playback music for about an hour with a short 10 minute charge. Given who this are intended for, that feature is something I like. While out, if the charge gets low on them, I isn’t going to take too long for me to get a reasonable charge on them in as little as 10 minutes. The charge case has a power indicator led on the bottom as well as a USB-C charge port. They come with a short USB-C to USB-A charge cable. The short cable fits easily in my pocket if I need to take it along with me, but the charging case is usually going to be enough for me. Ear Buds The ear buds are very light weight and look good. They are IPX4 rated, so sweating while wearing them isn’t something I’m worried about. Each ear bud has two mics. Calls I’ve has while using them have worked very well. The callers on the other end said they could hear me clearly. During calls, I did not experience any cut out neither did I experience any drop while listening to audio books and music. The sound quality is what I have come to expect from Sennheiser. Sennheiser says I should be able to get up to 6 hrs of playback time out of a charge of the ear buds. I got a little less than that, but it does depend on volume and other settings. The ear buds can pair with up to 8 devices. This is helpful to me because I have two tablets, two phones, an e-ink reader that can play audio books, and 2 laptops. It supports profiles for all of them. It will only playback audio from one device at a time, but that is common with multi-point pairing ear buds or head phones. I was happy to see this support with the Accentum Open ear buds. Another benefit is that the Accentum Open ear buds don’t require an app. You can perform all the controls from the ear buds. Just pair to a device and move on. That’s helpful to simplify getting them connected to a device without fuss. Final Thoughts I like the look and weight of the Accentums. The charge case is straight forward and of solid design. Not having to use an app with them is a big plus. In my use, I have yet to run into any problem with them. Sennheiser has a solid set of ear buds and charge case for sports enthusiasts. I hope to see Sennheiser continue on with the Accentum Open series ear buds. I would recommend considering them if you needs ear buds for exercising or sports activities.

This compact and capable TWS headphone is simple to use, provides great sound plus the ability to hear your surroundings whether they are on or off. The case is compact and battery life is quite good. No frills - just great Sennheiser sound in a simple set of “open” headphones. Highlights: * Tiny and lightweight case * Great sound * Can hear through without having to use a Transparency Mode * Comfortable * Good battery life (6hrs in buds, 28hrs with case) * Quick charge of 10 minutes for an hour of use * Multipoint connectivity * Remove to pause * No app Room for Improvement: * No wireless charging - have to plug in * Only status LED is on the bottom by the charging port * No ANC or passive sound blocking * No app for firmware updates or settings True wireless headphones are getting very feature-rich, but in doing so, they add a ton of complexity. While most don’t need apps to work, they almost require them to get the most of the buds. Plus, all of those extra features like Active Noise Cancellation usually necessitate more power and lower battery life. Setup: Unlike many others that may not require an app but highly recommend one for setup, this headset is super simple. Plug the case in to power for at least 15 seconds to “wake them up” from their shipping slumber. Then open the lid and they immediately go into pairing mode. Search for and select them in your mobile device’s Bluetooth settings and that’s it. Keep them plugged in for up to an hour or until the light next to the case’s charging port turns green. That’s it. No need for firmware updates. No settings to change. Just pair and enjoy. Usage: With no app to install, there are also no settings to change and no firmware to update. Put the buds in your ears and they play a short tone signifying that they’re ready to play but you can still hear your surroundings. Tap controls are listed on the included Quick Start guide. Start some music and you’ll be impressed with the sound quality typical of Sennheiser headphones. If you’re looking for a fully immersive experience and ultimate noise blocking; these are not the buds for you. These buds excel at great sound quality while also letting in your surroundings. Other buds have a “transparency mode” that uses their microphones to essentially pick up the outside side and pass that sound back into the earbuds, but that needs to be turned on or off and it uses power when on. These buds do it by not blocking your ears which means that they work this way all the time; sound playing or not. You can hear what’s going on around you blended in with the music, or pause the music and just be able to hear what’s going on without taking the buds out. If you do take them out, though, the music will pause and then resume when you put them back in. The tap gestures are pretty simple to learn and work well. Again, there’s no app to configure them. Instead, they are listed on the printed quick start guide in the box and are relatively similar to most other buds. A single tap on either plays or pauses, double tap on the left to skip back or the right to skip ahead, etc. Each gesture plays a short tone when recognized so you know it got it. Wireless charging is not included but the USB-C charging connector is common and easy enough. A quick charge of 10 minutes should give you about an hour’s playback and full charge can be done in about an hour for about 6 hours of music. Multipoint means that you can pair to up to 8 devices and keep the last two connected at the same time. This is super handy if you pair your phone and either tablet or computer. Expect few frills but these nail what’s important. Overall, these buds are refreshingly simple and effective. They are compact to carry, last a while on a charge, sound great when playing music, and let you remain connected to what’s going on around you even without removing them or turning on a special pass-through mode. If you don’t need buds that isolate you from the world with noise cancellation, then these buds might just be for you.
