I am 2 weeks into these headphones, a replacement for my Sony WMX1000Mk2 which came to the end of their life. These are amazing, must better sound than my Sonys and significantly more comfortable. The added touch of having Matt Berry provide all the quotes from “power on” to “Transparent” is genius.
If you are in the market for an excellent set of headphones and you want quality over trend I would recommend you walk on the wild side and by the P100’s.

These headphones get a lot of things right. The sound, the connectivity and the build seems great. The battery is amazing. Overall I am very satisfied.

Just a few minor gripes that I hope will get fixed by firmware updates - currently the headphones don't remember the last settings before shutting down, so if you want to use a specific setting like voice focus on transparency - you have to set it anew every time. The same is true for the 'gaming mode'. Currently I have to keep Bluetooth on in my phone in order to set those settings each startup even if I want to use the headphones with my PC. Another thing that stings a bit is the way they handle higher distances - my previous Bluetooth headphones would lower the quality a little at first and kept audio seamless when used on slightly higher distances, while P100 cut out for around 1 second before resuming function when dropping packets. Otherwise the range of the connection is excellent with a class 1 BT dongle and I'm hoping it will improve even further when I get my hands on a lossless aptX dongle as soon as those become available in Europe.

Very nice packing, awesome sound and most of all -at least for me- the battery!

I've been using a P100 connected to my PC through a Creative BT-W5 dongle for a few days now, and it's worked very well. Audio quality is great, and latency is acceptable for gaming and voice chat with the dongle set to low latency mode (though I would probably still use them wired for playing rhythm games). It's also been very comfortable, though I haven't worn it for longer than a couple hours at a time yet. The Android app sometimes takes a while to figure out that it's connected to the headphones, but updating firmware and adjusting settings were easy.

I do have a few minor complaints. The website has a statement about using aluminum in places for durability, followed by a picture where the arms connecting the headband to the earcups appear to be metal, but only the round part on the outside of the earcup is aluminum, so I have some concerns about longterm durability. The carrying case feels sturdy, but it only fits the headphones if you adjust the headband to its minimum size, so you have to readjust them every time you use it. The headphones also get incredibly loud. 10-15% volume is comfortable, and 50% is physically painful. I would love to see a volume limit function in a firmware update. The audio prompts for things like enabling ANC are also a bit louder than I'd like, so an option to adjust the volume of those would be nice too.
