Hmm, interesting. I will definitely consider it. B&O provides 15 days of trying while B&W allows 60 days. Do you think these wireless headphones require any burning in like with wired headphones? What I'm a bit concerned about is finding a BT adapter that will connect these headphones to my pc so I can try things other than just music, such as movies, flac files and movies. I also would want to compare the mic qualities so I would need an adapter that can both transmit and receive data - only one I found so far that does it while with APTX support is Sennheiser BTD800.. Argh, I am not sure if it will even work with these headphones.. I know p7 has 2 mics while h7 has 1 mic so I am curious how they match up for call quality.. I can try them on my Samsung Galaxy s6 as well. Basically, I would need to figure out music that goes both low and music that goes high in notes to compare bass and treble. Not sure yet.
