I am a longstanding Bluetooth user with in-ear headphones. I first used the various Shure devices with Bluetooth adapters, then the Shure Bluetooth adapter and finally the TW1. this is just information as a foundation to my review of the PI7. Bowers and Wilkins has been on my radar for some time as I also own the PX. Finally, I pulled the trigger on the PI7. There were on sale for $298
The sound is far superior to the Shure TW1 (with SE425). this is my comparison as the Shure devices combined were $189 +$299. The Shure TW2 with SE215 is now about $239 but the sound quality is not as good as the PI7. Yes, I have the SE215 as well.
The PI7 has better noise isolation. active canceling. There is no leakage. The room just disappears. The sound is three dimensional in my head. Listening to Ray of Light (Madonna) gives a good range of music as that song has so much production, one can hear it all.
I was debating whether or not to hold out for the next version as the battery power might be better but bought it anyway.
Not sure if I would have bought them for $399, but for $298, yes.
Also note the case acts as a Bluetooth transmitter. The volume needs to be pushed up a bit, but it still transmits. Good for flights. I already used one of these, but the combination means one less thing to carry.

Returned a new Sonos Play:5 which was half the price. The Wedge sound is so much cleaner and more spacious; great sound stage. Hard to believe it comes from such a relatively small (wireless!) package. Even pleases my wife with the Art Deco design. B&W Formation app works fine to set up. Very easy. Comes with 60-day trial of Roon which I highly recommend. Would absolutely buy again and feel it is well worth the $.

It is better than expected.

After 2 weeks,I have come to appreciate this item . This is the third item I bought from B&W and it won't be the last.

So I have the Shanling M8 ($1,650) DAP that I use for music, and normally I use my custom Valkyries ($1,600) and PWAudio cable ($1,000) for portable music, but I work in a clinic where sometimes we are slow, and I was thinking of a TWS for light classical or jazz while I am at work. I really didn't expect much, I have always disliked wireless because of the loss of sound quality. Well... I was delighted and shocked at how great the PI7 sounded! The bass is a little bloated, but it is deep and layered and there is great sub bass...mids and highs are perfect. Using the Hiby app on my M8, and the MSRB function, I cleaned up the bloat, and added some needed coolness....There is a 'pass through' mode that allows in ambient noise, and it was perfect... I tuned it through the app to the exact threshold that blocked out ambient noise, yet low enough if someone spoke to me I would hear them. Noise cancelling function isn't that great. I am not using stock tips, I am using after markets, the stock tips that came with my CL2. The PI7 may not be good for small ears. Excellent build quality, occasional micro drop outs... Secure twist and lock fit.

Excellent headphones, very comfortable, sound quality is great, very user friendly, Thanks

The use for tris headphone, its for personal use.
But I think, the product its great, but the price is expensive

Easy set up. Fantastic sound. Replacing my Dynaudio Music 7 and this is lovely sound. Thank you.

I've owned many types of headphones over the years. Wired as well as wireless. Frankly speaking you get what you pay for, though until now I would be reluctant to say that about wireless/Bluetooth headphones.

If your value the quality of sound over the bells and whistles of other brands then the PI7's will make you smile. It did me!

Now, having said that, and as others have said, ANC, and battery life are more than adequate, but not equal to some other brands. The iPhone app. isn't going to blow you away as it has few tweaks.

But I still insist the sound quality out of these wireless, In-Ear headphones are the very best I've heard. And that is coming from someone that usually uses a desktop amplifier and DAC. No, it doesn't beat them, BT technology is not there yet.

But when I go mobile I don't leave the house without the PI7. They even come in handy when I need to wander around the house, or relax on the deck, or cook in the kitchen.

If you can afford the price, they are well worth the price!
