The hype and internet consensus is justified: the Px7 S2s sound phenomenal. I prefer the soundstage over that of my Sony WH-1000XM5s, which I use for calls and on flights (or in other noisy situations), since their noise cancellation and microphones are definitely better than those on the Px7 S2. Compared to the Px7 S2s, the XM5s sound muddy and condensed, whereas the Px7 S2s feel expansive and crisp, while maintaining a robust lower register of bass to fill out the overall soundstage.

I'll cover 5 main areas in this review, often comparing the Px7 S2s to my experience with the Sony WH-1000XM5s (XM5s), the Airpods Max's (APMs), and the first-generation B&W Px7s:

1. Sound Quality
2. Build Quality
3. Bluetooth & Corded Connection Technology
4. Included Case
5. New Bowers & Wilkins App

"” SOUND QUALITY "”
I should preface this by saying that I purchased the Px7 S2s to be my listen-at-home-for-best-sound-quality-using-bluetooth headphones. I have a pair of open-back Beyerdynamic 990s that I use to mix and produce music, my XM5s for traveling and phone/video calls, the APMs (which I've since returned), the in-ear Sony WF-1000XM4s for the gym and exercising, and now these new Px7 S2s from B&W (which I'll just call "S2s" from here on).

It took a little time for the S2s to "run in", basically like "breaking in" any pair of headphones, over the course of about 24 hours of listening time "“ and the sound really just got better and better. I noticed better channel separation over time, especially when listening via the corded connection and internal DAC to get true HiFi sound (using TIDAL).

I did adjust the EQ in the app over time, basically increasing the bass by 4.5 dB and the treble by 2.5 dB to get even more dialed in to the sound I prefer. Now, the S2s offer an impressively wide soundstage with a level of detail and precision that I've never heard in any other pair of wireless headphones. The highs are clear and articulate, while the mids remain warm and rich, providing an incredibly immersive listening experience. I also appreciate that the S2s don't sacrifice bass response in pursuit of clarity; the low-end is powerful and well-defined, never overpowering or muddy. As a true audiophile, I can confidently say that the S2s deliver a level of Hi-Fi audio quality that is unmatched in the wireless headphone market.

"” BUILD QUALITY "”
When it comes to build quality, the S2s are simply outstanding. Crafted from a high-quality plastic that feels almost indistinguishable from aluminum or other light metals, the entire build of the headphones exudes a premium feel. The materials used make them lightweight yet durable, perfect for extended listening sessions without discomfort. The ear cups are plush and comfortable, providing excellent passive noise isolation. The S2s also boast a sleek and elegant design, making them as visually impressive as they are sonically.

"” BLUETOOTH & CORDED CONNECTION TECHNOLOGY "”
The S2s feature the latest Bluetooth technology, ensuring a stable and high-quality wireless connection. I've experienced no latency issues or connection drops, making for a seamless listening experience. The inclusion of a USB-C to 3.5mm cord and a USB-C to USB-C cord allows users to enjoy Hi-Res music quality, which is a fantastic addition for those who desire the best possible audio experience. I find that using the corded connection with the built-in DAC delivers superior sound quality compared to Bluetooth alone, especially when listening to lossless audio formats such as FLAC or TIDAL's Dolby Atmos tracks.

"” INCLUDED CASE "”
The Px7 S2s come with a fantastic case that is both functional and aesthetically pleasing. The case is smaller and less bulky than the XM5s, making it easier to carry around without taking up too much space. Made from a nice canvas-type material, the case feels durable and offers excellent protection for your headphones. The case is far superior to the AirPods Max's, which don't even come with a case, and it's clear that Bowers & Wilkins put thought into creating a case that is both protective and stylish.

"” NEW BOWERS & WILKINS APP "”
The Bowers & Wilkins music app is a fantastic addition to the Px7 S2 experience. The app enables you to adjust EQ settings, including treble and bass, allowing you to fine-tune your listening experience to your preferences. Additionally, the app integrates multiple streaming platforms like TIDAL, Spotify, and Soundcloud into one centralized music hub, making it easy to access and enjoy all your favorite music from a single location.

I particularly appreciate the ability to listen to TIDAL's Dolby Atmos songs in a standard FLAC format, which sounds much better to my ears. The app is user-friendly and responsive, and I find it to be a valuable tool in getting the most out of my Px7 S2s.

"” FINAL THOUGHTS "”
Ultimately, the Bowers & Wilkins Px7 S2 over-ear headphones have exceeded my expectations in every way. With unparalleled sound quality, exceptional build quality, versatile connection options, a fantastic case, and a highly functional app, the Px7 S2s have quickly become my go-to headphones for enjoying Hi-Fi audio at home. As an audiophile, I can confidently say that these headphones offer a listening experience that is unmatched in the wireless market. If you're seeking a truly premium audio experience, look no further than the Px7 S2s.

I love these headphones! Upgraded from Bose and I will never go back. Physical quality is far superior to Bose. Very comfortable; I wear them all day working from home. Ears never overheat or sweat (had those problems w Bose 700). Music sounds fuller than Bose. Easily connects to two devices and telephone mic is excellent. ANC is excellent. Battery life w ANC is amazing - used for 2 days w/o charging. The blue is beautiful & love the case. Out of the box, these are fabulous. Better than Bose 700 & QC45.

For me everything is ok with these headphones all good. The only issue is that when you activate the noise cancellation the sound is as if you were hearing it from a can.
I think manufacturers should remove the noise cancellation on this model because the sound quality when you use noise cancellation leaves much to be desired.
But in general for me it is what I need, but I am sure that under other circumstances I think I would return the purchase and buy the more updated model. For now I don't need more than this because I live in a tranquil place and there is no need to reduce external noise.
The sound quality is as good as the models with more extras and if I want a bigger bass sound effect, I simply increase the bass on my computer's equalizer.
There is not the slightest need to use the application.

The Bowers & Wilkins Px7 S2 headphones are a mixed bag. In terms of sound quality, they are unparalleled in their price range, and the digital audio streaming functionality via USB cable is a great addition. However, for the price tag ($400), I would expect better build quality. Specifically, the material covering the ear cups and the headband peels off easily, something I experienced after just 6 months of moderate use. Although I chose to buy replacements for the damaged parts, it's an issue that shouldn't exist in a product of this caliber.

I'm really liking these so far. This is just from a few hours of listening to music today, about 4 hours I would say. I did quite a bit of research on these and they weren't my first choice. I already own the Plantronics Back Beat Pro 2's since June of 2017 and the Audio Technica ATH-DSR7BT since October of 2017 and I've been happy with them both. I auditioned the Bose QC35 back in June of 2017 and decided on the BB Pro 2's. The Bose to my ears just didn't let the music come through, made me feel like I was in a "pressure cabin" or something and I couldn't even switch ANC off. Anyway I wanted another pair of ANC headphones to rotate in my daily listening. In the morning after checking my HRV the headphones go on and I actually wash my face and brush my teeth with them on, I do take them off before I shower. I was going to sell the Audio Technica but couldn't find a reason, to me they really let the music come through. I like the way the BB Pro 2's sound too, although they can be a little heavy on the bass, but the music is enjoyable and the Pro 2's are feature rich.

Now to add another set of ANC cans to my rotation I had Sony WH1000xm2 in mind. I actually ordered them and while they were on the way to me I kept reading about the cracking head band piece so when they got here I picked them up from UPS and didn't even bother to open the box and just sent them back. I also considered the Sennheiser PXC 550 but decided not to get those because they didn't support AAC (I own the Senn HD-700 wired as well as the Senn HD-598 wired just for reference). Although I do have an Android phone that supports aptX and aptX HD this is the phone I run and exercise with. Now I did do some comparisons between my iPhone using AAC and the Android phone using aptX HD and to be honest I couldn't hear the difference, maybe it's my old ears or something but the music I listened to sounded good using either codec on either phone. Anyway even if I couldn't hear the difference I wanted something that supported all the codecs out there, who knows, maybe I'll experience a miracle and be able to here the difference one day, in other words I want to be ready even if I don't get to go!
So I ordered the B&W PX's (B&W is what we called the company back when their 801 reference speakers hit the scene). B&W, like Audio Technica as well as Sennheiser has a history of making various devices, equipment in the audio reproduction/recording industry (I guess Bose too with their in the corner 901's I think?). Anywho I got my PX's today and I love them and read that they get better after some burn in time, who knows?. The first thing I did was plug them in, turn them on, connect them to the app and update the firmware. So far everything has been going smooth. The only thing I kind of dislike is the power button. Why not a regular slider or rocker switch that stays in the position of off or on? Other than that it's pretty straight forward. The music shines, just comes through on my iPhone X. I have to say to my ears the PX's are on the neutral side of the spectrum, where as the BB Pro 2's are on the "warm" leaning towards a fatter bottom end. The ATH7's are more neutral as well. the PX's and the ATH7's to my ears are really close in their presentation. This is just my initial observation and opinion and like I said to my ears and perceived matched volume level. I did notice that on a particular recording (India Arie) there's some distortion (bass riff) in the recording that I had not noticed until listening to the PX's. I first thought that something was wrong so I went to the ATH7's and heard the same thing, but not as pronounced as on the PX's. Don't know why, maybe it's because of the different sensitivity between the two cans. I didn't listen on the BB Pro 2's yet but will and maybe I'll add more to this note of my experience.

I also read that to some the clamping force or fitment of the headband on the PX's were a little uncomfortable to them, to me they're just fine. I didn't experience any heating up of the ear cuffs around my ears either. I'm a big sweater, I perspire just sitting around so It'll be interesting this summer but I do have air conditioning in my home, thank goodness :). I don't expect any problems. I've used my BB Pro 2's while cutting my grass but not sure if I'll bring my PX's outside use while cutting grass. anyway over the last few months I've acquired some really good sounding LG and Sony earbuds that have passive noise cancelling that I use when I run outdoors so the Pro 2's are relieved of outdoor duty too. As far as comfort I would say the ATH7's then the BB Pro 2's then the PX's. This could change in time after I get used to them and or the pads get softer or broken in. The pads or ear cups can easily be replaced on the PX's too so who's to say that B&W won't make some that are softer. The PX's are keepers for me! I forgot to mention the ear pads/cuffs fit over my ears (ears are inside the cuffs) and form a perfect seal.

Update: 3/12/18: Very revealing. If it's a good recording then then that's what I hear. Listening to a compilation of female vocalists. Natalie Merchant; "Cowboy Romance", layered, open and her husky voice is right there. Instruments, not sure what they are but could some kind of synth sounding like maybe an organ, violins and some stringed instruments are very harmonic. India Arie; "The One" another very good sounding recording to me. Nice bass lines, guitar strumming and everything just sounds so good. Her mature silky voice just comes through. I noticed on Norah Jones "What am I to You" sounds a little vailed, not as open as the first 2 I mentioned. I believe this is more to do with the recording. Her voice is still immediate and sounds very good. Organs, drums and guitar are very noticeable but the recording itself is just not as open and airy, still sounds good though. Sarah Bariellas "Love Song" sounds pretty open and well recorded, her voice is just right there along with the piano and accompanying instruments, drums, guitar etc. right there. Alanis Morissette "All I Really Want", her squeaky high pitched voice and rhythmic drums, and what sounds like an harmonica and organ, just have to move, pat my feet!. Just a sample of how enjoyable these are to me. I listen to a wide variety of music, to the above mentioned to "Red Hot Chili Peppers", "Sheryl Crow", "Adele", "Maroon 5", "Parliament/Funkadelic" and on and on. Just love what I call music and the different expressions. And the added features of the PX's are a plus. I haven't used the various filters a lot but just played around with them and to my ears they don't distract much from the music and works pretty good. I don't use the "proximity sensor" thing, I don't really care for it on the BB Pro 2's either so I leave it off, on both headphones. I like the position of the controls and they work pretty good, as I said I don't care for the on/off button, it order for me to get it to work right I have to hold the headset in my hands, so turning them on and off I'm holding them, not a problem though, just the way it is for now. Maybe it'll change once I'm used to it. So that's it. I'm done. These are excellent to me. Like I said, "Revealing" , what you got (recording) is what you hear. Also I'm using Tidal HiFi downloaded recordings to my iPhone X. I haven't listened with my Android (LG G5) yet but mainly use that for exercising, running and gym but I'll get around to connecting them to it sooner or later. Sorry for the rant, hopefully you can get my point.
