Bought these to replace my broken Sony WH-1000M5. The P100 build quality is great. They feel solid and are really comfortable to wear. Set up and pairing was easy. The sound quality is amazing, clear and precise. I am hearing sounds that I never did compared to the Sony ones I had. Music feels much more enjoyable to listen to. I use these also for my work and meetings and even with this they out perform the Sony ones. The noise cancellation is also good as well. Overall very happy with the P100 and would highly recommend them.

These headphones have almost everything going for them. Fantastic audio quality rivaling the competition and for a noticably lower price. Build quality is strong, but I'm not sure I like the lack of an ability to fold up, meaning that these are not very portable. Their case, because of this, is absolutely gargantuan and not something you'll be carrying unless you have a dedicated bag. The headphones themselves, while comfortable, do have a noticably large profile while on your head, sticking out about 2 inches on each side, so do not expect to be subtle with these on. The button controls it has are fine and not easy to accidentally press, and I appreciate that the app gives some ways to customize them (along with a decent EQ). That being said, it's noise cancelling does have some notable issues that do reduce the quality of sounds, and it unfortunately doesn't seem to be a software issue. On top of that, the effectiveness of the ANC largely relies on fitting the headphones perfectly to your ears and head, which can be difficult to accomplish and keep, but if all goes well, the ANC can be quite effective. While it does offer a wired option, it's almost impossible to use at the time of writing. The headphones must be turned on to use it, which I am not a fan of, but it does not disable wireless connections while wired, and this means that it connects to your devices through Bluetooth and any sounds coming through the wireless device will completely override the wired sound. I desperately hope this is something that will be fixed with future software updates. Voice prompts are something that really matter to me, since they're heard every time the headphones are turned on, and I'm glad to say that these are as good as it gets. It's quick and snappy, doesn't waste your time, so when you click the power switch you're immediately able to get back in to music and sound. Overall, I'm extremely happy with these headphones despite their flaws. They shake up the very very small market of ANC premium headphones and they do it very well. Because they have a much lower price compared to the competition in its market, it makes it easy to recommend these to anyone wanting to invest a little into their sound quality. I look forward to what the next model of these could bring.

Very good sound for the price/performance ratio. Only the headband has a not entirely pleasant, soft quality and presses a little. A material like the ear pads would have been a better choice here. For the first over-the-ear headphones, it's a good start with potential for improvement for future generations.

I really love my new headphones. Great sound. Excellent quality. All at a great price. I am very happy with this purchase.
