I've been using my On-Ear Wireless Momentums quite well with both my iPhone and iPad however, my Macbook Pro 2011 was horrid, I couldn't move more than 20cm away from it, the signal was always around -75dbm. Then I realised that any Bluetooth periphery wouldn't work reliably, not just the...

I can confirm that El Capitan GM fixes things, the last two betas were dreadful, Bluetooth was completely broken (not just with the Momentums). iOS 9.1 beta works wonderfully, as all the 9 betas did before

My Momentum Over Ear Wireless work perfectly well with my iPhone 5 and my iPad Air, with my Macbook Pro 15" 2011 (El Capitan Beta) they sometimes stutter if they connect automatically, if I connect them trough the bluetooth menu in my Mac they work fine.

I use quite often and haven't had any complaints yet, quite defined and good isolation from ambiente noises

I find great, use it sometimes and people claim they can hear perfectly well without much background noise.
