Alright, I've had these guys for about a week now, and these babies are bluetooth audio bliss for me. With their slightly meatier bass presence, very solid isolation, very solid separation for closed cans, and overall stellar clarity across the spectrum...these are without doubt a killer sounding set of headphones.
The earcups fit fully around both ears without issues, and isolate very very well.
The headband does apply some pressure to the top of the head which isn't the best, I wish the padding up top was a bit more forgiving.
The bluetooth connectivity has been the most solid of all the ones I've tested to date (B&W P5 Wireless, VModa Crossfade Wireless, M&D MW60). The AAC support paired with my Apple Music library goes together hand in hand. There is the slightest bit of latency perceptible while watching videos, but even for someone like me who LOATHES this, it is minor enough that it isn't a bother.
When two devices are connected at the same time, any competition to put sound out on the headphone essentially breaks the bluetooth connectivity. You'll end up not hearing either clearly and get tons of breakup. This can be an issue if you have your phone hooked up and are listening to music on your computer, for instance. The text sound will disrupt the stream from the computer and garble up the signal for a good 5 seconds before returning to function again. When devices are playing audio one at a time, all is well.
But the sound in these is just so great. The bass in them are just perfect to my ears. It presents all of the detail while giving you just enough of an "oomph" to let you feel it. It doesn't impede dramatically into the mids. It DOES impede slightly when the bass is going insane, but even in these instances it is fairly forgivable. The highs sound crisp and clear. A very clear cut example of a V-shaped sound signature, that I love dearly.
Battery life on them has been totally fine. I use them aggressively for 2 days and it makes it before I feel the need to recharge. I haven't had them die on me yet, but I do make sure I'm charging them almost daily.
The biggest cons I could really attribute to them is that they aren't very portable friendly (despite folding up, they still have a big footprint in your bag), the headband applies a little too much pressure to the head, and the dual device bluetooth connectivity has some wonks when there are competing sounds.
The biggest pros are the beautiful sound signature and detailing, the great isolation and the rock solid bluetooth connectivity.
Coming from a pair of custom in-ears (1964 Qi), I was worried I wouldn't get the intimacy and detail I'd been enjoying. I can safely say that the P7s hold their own in sound signature and quality, without the wires. In a fully quiet room, I dare say I prefer my P7s because of the better instrument separation and more full bodied bass impact.
Definitely a great choice, and my choice between all the bluetooth units I listed above for daily train commuting.
