I have owned many headphones in the past, but these are some of the best noise canceling and audio file headphone I have ever owned. They are very comfortable to wear and when they are set to transparent mode you are able to hear people around you no problem.

📦 UNBOXING: Inside the box, you’ll find the headphone case with the headphone inside, and some documentation to get started. Inside the case, you’ll find a nice USB Type-C to Type-C cable, and a USB-C to 3.5mm cable for analog audio. 💪 BUILD: Upon first impression, the hard case is very sturdy and doesn’t flex, so it won’t compress when put in a bag. The magnetic flap inside the case is strong so you shouldn’t have any problems keeping the cables organized. The headphone itself is fairly lightweight and uses primarily plastic for its construction with some metal, as well as fabric on the back of the ear cups. The earcups rotate 180 degrees to get a good fit for many head shapes, and the headband seems to flex reasonably wide for larger heads. ⚙️ CONTROLS: On the left ear cup, you’ll find the power/pairing switch as well as the quick action button which by default toggles between ANC, Transparency and Off. You can change the quick action button to toggle your voice assistant instead, but I don’t see why anybody would want that. Many other headphones allow you to hold the play/pause button to spawn your voice assistant, but that doesn’t work here. The right ear cup has the play/pause button and volume up and down buttons. You can also navigate tracks by double-pressing to go forward a track or triple-pressing to go backward. You can also use the play/pause button to answer, reject or end calls with a tutorial in the app to explain every control. One thing that I really like is how responsive the wear sensor is. Whenever I lift an ear cup off my head or remove the headphones, the playback immediately pauses. You can adjust this sensitivity or completely disable this behavior from the app. As for complaints, I think the only thing I dislike about these physical controls is that they’re quite small, so it can be a bit hard to find them at first, but I’ve acclimated pretty quickly. Another thing I would have liked to see would be a way to switch which devices the headphone was connected to via the power toggle on the left ear cup. As it stands right now, a quick slide up on that switch currently does nothing. I think it could be an intuitive way to switch devices without needing to use your app to tell the headphone which device to reconnect to, or manually connecting to the headphone via the device itself. With that said, the headphone does connect to two devices simultaneously. If I’m playing music on my laptop, but switch to a music app on my phone, it immediately pauses playback on my laptop and begins playback on my phone. In my experience, this has probably been one of the best executions of this feature I’ve experienced yet, as it works quickly and reliably. ☁️ COMFORT: The Px7 S3 has a shallower ear cup compared to some other headphones, and while it doesn’t feel spacious, it also doesn’t feel confined to me. The headband padding is plush and provides decent comfort for the apex of your scalp so you don’t feel pain. The clamp force isn’t egregious out of the box, so I had a comfortable listening experience from the start. The ear pads are also plush so they won’t cause unnecessary pressure on your jaw, and I’m able to get a closed seal so there aren't any issues with noise leakage. 🎧 SOUND QUALITY: Out of the box, the Px7 S3’s “True Sound” EQ profile has a bassy sound profile with a touch of bloat into the midrange, but I did not find the bloat to dramatically influence my listening experience. For R&B, Hip Hop, Pop and Electronic, this stock sound profile can be very pleasant, as it lets vocals through cleanly while also delivering exciting bass performance without muddying the instrumentation. For metal, rock and alternative, I think the Px7 S3 could sometimes deliver more bass than desirable as it steals some energy from the midrange where guitars will be most prevalent. However, the 5-band EQ lets you adjust this in 0.5dB increments. It’s not exactly clear which frequencies Bowers & Wilkins lets you control in their EQ since it simply has labels for LO, MID and HI. But I did overall find that it was reasonably effective in obtaining a more pleasant sound profile to my ears. The headphone has a more intimate sound stage, but instrument separation is good and vocals stay centered in the mix without being too prominent or too small. Compared to the competition for ANC headphones around this price range, I think the Px7 S3 is one of the bassier headphones I’ve tested, but one that delivers bass with good control, low distortion, and packs a punch without severely compromising the midrange. The treble to me, is normally a touch warm for some of my music which is great for avoiding fatigue, but there is a bit of sibilance which might be more prevalent for some music libraries, so EQ can become your friend if you encounter that. I also appreciate that you can use the headphone in a wired USB-C configuration with the internal DAC. It does charge while in use, and you do need to power the headphone on to use it wired. At the time of writing, Bowers & Wilkins is working on a spatial audio implementation that will come in a future firmware update. 🔊 ANC / AMBIENT SOUND: The ANC performance is a notch lower than the mainstays in ANC headphones, but it is still quite good. If ANC performance is higher on your priority list compared to sound quality, then you will probably want to consider the latest options from the competition, but if you want to prioritize sound quality over ANC, I do think the Px7 S3 is a solid performer. The sound of children shouting and screaming will still manage to peak in, but during music playback it’s much less distracting—especially on busier tracks. Many other headphones have the ability to control ANC strength, but that doesn’t appear to be an option with this headphone. Personally, it’s not something I usually care about, as I don’t feel a strong pressure effect on the Px7 S3, and if I want to hear noise, I can just turn on the Transparency mode or turn off ANC. Speaking of the transparency mode, it sounds like a thin veil is placed over your ears, so you lose some clarity and a bit of loudness, but it’s quite good. I don’t hear a grainy noise floor like some other headphones when the transparency mode is enabled. 🎙️ MICROPHONE QUALITY: There are 8 microphones in total, with 4 mics per earcup. Bowers & Wilkins claims that on each ear cup is 1x Feedback microphone and 2x Feed-Forward microphones, and these are used especially for the noise cancellation. However, all 8 microphones are also used during calls to isolate speech from background noise and to deliver clear speech audio. In my testing, I find that the sound signature leans warm, but not muffled. If you’re speaking quietly, it may struggle to pick up your voice, but these would be great for conference calls and phone calls, alike. During USB-C usage, the microphone appears as a 1-channel 16 bit 3200MHz device, so you can use it for better microphone quality during conference calls or even gaming on Discord in a pinch. 📱 SOFTWARE: The app requires you to create a Bowers & Wilkins account, which I don’t love, but that appears to be the trend these days. The app provides firmware updates, switching between your custom EQs, pairing, removing and connecting to different devices, and toggling between your environment modes. You can also toggle the auto standby mode or the wear sensor. Eventually, they’ll be providing their spatial audio feature and Bluetooth LE Audio through a firmware update. 🔋 BATTERY: Bowers & Wilkins claims you can get 30 hours of playback with ANC enabled, and it only requires a 15 minute charge to get 7 hours of playback. This is on-par with the competition’s playback time with ANC enabled, so you won’t feel like you’re making a compromise here. 🧐 CONCLUSION: Overall, I feel that the Bowers & Wilkins Px7 S3 is a good all-rounder ANC headphone. It has a nice premium hard case, and the design aesthetic leans premium and elegant. But it does very well when it comes to out-of-box sound quality compared to a lot of other premium headphones in this price bracket. While I think its ANC is a notch below the leaders of this category, I also find that the Px7 S3 prioritizes better sound in a way that the market leaders don’t. Moreover, the fact that you can use it in a USB-C DAC mode with good microphone support makes it more versatile for those moments where there might be too much wireless interference or you simply need lower latency.

I’m using these with an Apple iPhone 16 PRO, iOS v18.6. If you take your music very seriously, you will not be disappointed at all with the Bowers & Wilkins Px7 S3 Noise Cancelling Wireless Headphones (from this point forward, I’ll refer to them as “B&W Headphones”). The sound is rich, crystal clear, well-balanced, and powerful. No matter what the genre. The bass response is impressive, although in songs that are bass-heavy, the 40mm drivers bottom out (mechanical distortion) even under moderate volume; this is not necessarily the case with all 40mm drivers generally speaking. This issue can typically be eliminated by adjusting the iPhone’s equalizer. The distortion does not occur frequently, is dependent on the song and volume, and should not be reason for a ‘buy / don’t buy’ decision alone. These work great for iPhone users, but, the B&W Headphones are not truly HiFi/lossless (see the last paragraph of this review). The B&W Headphones feel much like silk against your ears, and hold tight enough to your head so they don’t move, while remaining incredibly comfortable for hours of continuous use. These are pretty remarkable. The ear cups are thin, so they look and feel lighter (not clunky). The app is visually pleasing to look at and use, and the B&W Headphones pair effortlessly. I like apps like this to look ‘clean’ with the ability to hide information that you don’t need or want. There is an area called ‘Curated By Bowers & Wilkins’ that include selections for podcasts and sample play lists that you cannot hide or otherwise get rid of. There is also a feature called ‘Add More Music’, where you can link your favorite music streaming services. There is a lengthy list, but it does not include Spotify, Apple Music, or Amazon Music, all of which are in the Top 4 music streaming services for 2025. This is a big miss in my opinion; I’m not able to link my streaming service, yet I have to look at the feature in bold on the app’s Home screen. Let me hide the feature and/or put it under its own Menu/dropdown. For me, it totally muddies up the app’s aesthetic. It functions very well however. Other Items: ***The three buttons on the right ear cup (volume, play/pause/rewind/skip ahead) are too small and/or thin. So if I need to pause music, or move to a different track, it’s easy for my thumb to hit the wrong button, and I spend time feeling them out, and sometimes just pull out my iPhone to adjust what I need to. ***The ANC (Active Noise Cancellation) is not completely effective. It does work great, but there are times where ambient sound is not cancelled (an example would be an air conditioner or fan in the background). ***On a full charge, the battery is impressive; it lasts for a really long time, even with increased volume and the ANC on. ***The carrying case is very sturdy, and even includes a compartment for a USB-C cable. In consideration of audiophiles, the B&W Headphones support advanced Bluetooth codecs like LDAC and aptX Adaptive, but iPhone users are limited to AAC — so you won’t get true lossless or Hi-Fi wireless playback. If you want to bypass that limitation, the headphones can also be used over USB-C, which avoids AAC compression by sending a direct digital signal into the B&W Headphones internal DAC and amp. It’s not a pure analog passthrough, but it does deliver cleaner sound than Bluetooth on iOS.

The Px7 S3 combines excellent sound quality and good noise cancelation with a very comfortable headset! Design The Px7 S3 headphones have a clean, elegant, design that's rounded all over. There's a nice textured fabric on the top of the headband. The bottom of the headband has a smooth surface with a very comfortable padding, the part that goes against your head. That same soft material is on the earpiece pads that go over your ear. I find the headphones very comfortable to wear, both in weight and fit. There's a slight angle to the ear pieces so the bottom goes in a bit farther than the top of them, as I think they should be, or at least for a snug fit on my head. It also includes a case with a what looks like a molded fit for the headphones. The case also has a compartment which hold the included USB C to USB C charging cable and the included USB C to 1/8" Stereo (headphone jack) cable. Please see the included pictures showing the case and the cables. My Px7 S3 is the "Indigo Blue" color. Sometimes it's hard to tell in pictures, so for what it's worth, I think it looks more like purple and less like blue. There are four mics on each earpiece (eight mics total) for voice pickup and noise cancellation. It supports a number of Bluetooth codecs, AptX Lossless, AptX Adaptive, AptX HD, AptX Classic, ACC, and SBC. Controls The controls are in the inner perimeter of the outside of the headphones instead of the very outside, as with some headphones. I think this is helpful so I'm less likely to press buttons if I don't want to when taking the headphones off or putting them on. The buttons have a good feel to them. They're very easy to press but I can tell when they've been pressed and can feel for them without pressing them by accident. The right earpiece has play/pause, volume up, and volume down. Personally I prefer having a dial for the volume but the up/down buttons work well. It can also be used for answering (play button) and hanging up calls (double press play button) and Next/Previous track (double and triple-press on the play button respectively). Probably my favorite control implementation is that it pauses music when you take the headphones off, or even just lift one side, and then resumes playback when you put it back on. You can adjust the sensitivity of the auto-pause when removing in the app. The left side has the Power/Bluetooth switch and a configurable "Quick Action" button that I'll talk about later. Music | Bowers & Wilkins App Besides great sound quality, there's the "Music | Bowers & Wilkins" app that adds a few options. There's an "Advanced EQ". This gives you a 5 band graphic equalizer. You can use the default "True Sound" which looks flat, all bands at 0. It says "Experience audio with the authenticity of the original recording - nothing added, nothing taken away", so that makes sense, and it does sound great and natural, unaltered to my ear. Even with the default setting the sound is extremely rich to me. Most of the time I'm listening I have Dolby enabled on my phone or my laptop just because I normally do, but I've turned that off too and is still sounds great, just a bit less full - as it should sound less full without the Dolby modifications to the audio. Besides "True Sound" there is a "Custom" option. It's very easy to make and save your own pre-sets. I created three settings, one to boost Bass, one to boost Treble and one called Boost that boosts Bass and Treble but not the mid range. Each works as it should. With some music my Bass boost setting made the music sound muddled, but it did really make the excellent bass even more bass-y. I can switch between them instantly in the app while listening. You can also use the app to change the "Environment" setting from "Noise Cancellation", "Pass-Through", or "Off". There's a "Quick Action" button on the headphones that by default toggles through the three "Environment Control" settings. You can configure that button to launch your Voice Assistant if you want. I wish there was an option there to toggle through Advance EQ settings, but maybe they'll add that in a software update. You can also link the app to any of the following streaming services: qobuz, Tidal, deezer, Amazon Music, pandora, TuneIn, SoundCloud, and NTS. I think they're all services that support very high quality audio. Sound, Calling, and Noise Cancelation The sound of these headphones has impressed me a lot. For one thing, the bass is excellent, not deep and messy, deep and tight - clear and rich. Not only is the bass great, but it produces clear and rich vocals while playing bass. It seems very well balanced and strong at all frequencies. I used it with the headphone jack adapter (included) connected to my laptop for playing games and man, there are nuanced sounds that I normally don't hear but can hear clearly using these headphones! In a soccer game all the sounds of the crowd and other background noises come through so well, it was like a new experience. It's the kind of thing where I didn't realize what I was missing until I tried with these headphones. I also tested it with calling over a Bluetooth connection to my cell phone and was impressed again! Of course with the headphones on, I could hear the person I was talking with very clearly. The cooler things was that with music playing loudly in the background, in the room I was in, the person who I was talking with could still hear me very loud and clear. They could tell there was some music in the background but couldn't even tell which song it was until I turned it up even louder. Even then I was still loud and clear for them, making it easy to carry on a conversation while the loud music was playing. I could hear the music but it was soft enough for me to still talk on the phone as well. If you need to take phone calls in noisy environments, the Px7 S3 could be the perfect option for you! Overall the noise cancellation worked well. I wasn't impressed with it in some situations. Some quite sounds didn't seem to be canceled out, others, like the fan on my laptop, were totally canceled from what I could hear. For instance, I may hear someone talking next to me, through my head maybe, but if they were in another room trying to talk with me they would eventually come over because I couldn't hear a word they were saying. One great thing about the noise cancelation in these headphones is I've used some similar headphones that create what to me is a very noticeable "pressure" for lack of a better word, to do the noise cancelation. It's not anything you can hear but it really just feels like pressure on your head or ears. It didn't really bother me but I like that these don't do that, at least that I can notice. Summary The Px7 S3 from Bowers & Wilkens is a great set of headphones with excellent sound reproduction and some helpful features. They produce deep bass and rich treble, and everything in-between with perfect clarity! If you're looking for great sounding headphones with noise cancelation, this is a pair you should consider!

I've been putting these Px7 S3s through their paces and they have quickly become my go to headphones for work, travel, and even when doing tasks around the house. As a techie, I've owned a countless amount of bluetooth and wireless headphones over the last couple of decades. These are by far the best sounding ANC bluetooth headphones that I've had the pleasure of owning; specifically for music listening. Not only that, but they seem to offer some of the best design and construction available in the current market (at least as of Q3 2025). The fit and build quality is exceptional. The Px7 S3s are constructed from aluminum, premium plastics, nylon fabrics, synthetic leather, and memory foam. When holding them in your hands, you can tell that you're holding a high end product. I love the use of intricately woven nylon fabric on the top of the headband and around the exterior of the earcups. The top of the headband is an area that usually takes a lot of abuse and this rigid nylon fabric feels like it will hold up well over time. The headband extension feels very sturdy and glides like butter when lengthening or shortening the headband to fit my head. The swivel points on the headband also pivot very smoothly. They are built extremely solid and to a very high degree. The execution in build quality is simply second to none. I can also attest that these are some of the most comfortable headphones that have ever braced my head. The memory foam on the leatherette earcups, and underside of the headband, are exquisitely soft and supple. Bowers & Wilkins perfectly nailed just the right amount of clamping force on the headband too. It's just tight enough to create a really good seal on your ears, to prevent audio leakage, but not too tight to the point where you start feeling clamping fatigue after long listening sessions. Due to the carefully curated choice of construction materials, the headphones feel lightweight and very low profile. This makes these Px7 S3s perfect for on the go and travel. The audio quality for music listening is where the Px7 S3s truly shine. By default, the Px7 S3s are tuned with Bowers & Wilkins "True Sound" which maintains a relatively balanced sound signature. I quite enjoy the default pre-set for most of the genres I listen to (i.e. Jazz, metal, classical, electronic, country, blues, hip hop). However, the Bowers & Wilkins app is a must download in my opinion. Certain albums I listened to really benefited from the boosted lows or mids. Once tuned using the EQ, I was able to get some phenomenal sound. Highs and mids were very detailed with good separation. While the best instrument discernibility I've ever heard was from open back headphones, the Px7 S3s are quite impressive for closed backs. When listening to more vocal tracks, the sound is very present and natural. The low frequency produces the style of bass that I love the most; tight and controlled versus overly sustained. Watching movies surprisingly sounded good as well. The dialogue was very forward sounding and clear. Explosions sounded pronounced and without any type of distortion. The active noise cancellation (ANC) and call quality are also superb. I have been using these daily at work and on the subway during my commute. I work in a very noisy office environment and when I had active noise cancellation enabled, all external noise was completely muted which allowed me to focus on my work. This was also the case on the subway. Coupled with a good seal around the ears, I cant stress how good of a job Bowers & Wilkins did on the noise cancellation aspect of these headphones. I also love the pass-through feature for the office. You can either quickly access the button at the top of the left earcup, or toggle it on using the Bowers & Wilkins app. It did a great job of allowing some of the ambient sound in so that I could hear my co-workers if they were calling me over for something. Call quality was also good. I've made several calls throughout the week and asked my colleagues and friends how I sounded and they all said I said sounded clear with no drops in quality. Overall, I love my new Px7 S3s. They are the best bluetooth headphones I've owned. Oh, I almost forgot to mention. They are also the absolute best bluetooth pairing and multi-device bluetooth switching headphones I've ever tried (you can switch between two devices at once and pair up to 8 devices). They are flawless when pairing with any BT device. Switching over from one device to another is seamless and quick. Do bear in mind that you can only listen to one source at time though. The only two minor caveats I have is that I wish the earcups were real leather (to increase longevity) and wish that there were replaceable earcups that you could purchase directly Bowers & Wilkins website. As we all know, leatherette, or even real leather for that matter, can start flaking off after several years or months of hard wear and tear. I would have loved to have seen an option to buy additional earcups, or even velour pads, as an option. Other than that, these are a 5 star product. I highly recommend checking these out if you're in the market for a high end set of bluetooth headphones with fantastic active noise cancellation!
