Of course, the reason you spend big bucks on a headset like this is for the noise suppression, and here is where the Bose headsets excel. For those having the sub disconnect I fixed it by doing the following:- Turn off Eco mode. For me battery life and the connection quality was the highest on my list of needs for bluetooth earbuds and this pair excels at both. The slippers are so very comfy & I love the squirrel on them. Den Stecker für die Elektrik noch dran und schon gehts an die Überprüfung der Beleuchtung. If you dont think these have GREAT mids, flat or not, there is something wrong with you. However the comfort falls short, bluetooth audio in general is awful, the features kind of suffer compared to other headsets at this price range. does the job. Play some good quality audio through these and they will do better then their price tag. Only thing is, Ill probably end up having to buy another one in a year, because of the thin footbed.
