First a bit of background. I've been working from home for the last 7 years, but I have taken a new job which means I will be out of the house 12 hours a day. It seems pointless having a nice setup at home and crappy portables if I'm going to be using the portable headphones 90% of the time, so (with much reluctance) I'm selling my Beyerdynamic T90s, dac, and amp, and buying the best bluetooth headphones money can buy....... From reading reviews I thought the best ones were the Sennheiser Momentum 2.0 Wireless, so I bought them. I am not impressed with them at all. Now I know it may be unfair to compare the Beyerdynamic T90s to bluetooth headphones, but I picked up the T90s unused, opened box, for £270. I paid £350 for Momentums and they don't even come close. Nowhere near. I listen to a wide range of music genres, including a lot of EDM, and the bass is soooo muddy compared to the T90s. I'm not expecting the same sound quality, but I would like something that sounds good. I will be sending the Momentums back tomorrow. After a bit more research I have narrowed it down to the Beoplay H9s or the B&W P7 Wireless. I'm going to listen to some P7Ws tomorrow, but I have no way to test a pair of Beoplay H9s. Does anyone have experience with either of these? Or any others I haven't considered? Any help would be appreciated. EDIT. The most important thing to me is sound quality. ANC is not important. Comfort is important but not nearly as important as SQ. And I definitely want wireless.
