I received these yesterday and after a full charge paired them with my phone and started listening to music. After three hours my batteries were showing 70% so it looks like the 5 hour stated time might be a bit short. Today I started testing again late morning and after five hours I'm at 60% charge. The recharge when I put them back in the case last night was quick, likely because it wasn't very far down. I don't know about you but short battery life is a pet peeve and there's none of that here.Sound is great, much better bass than some of the other buds I've tried (and I have tried a bunch of different ones). Volume adjustment is easy (tap one side to raise, the other side to lower). The tap interface is pretty intuitive, no buttons to push, just touch the device.I've taken a few calls and the callers have all complimented the sound quality, they're not picking up any background sounds. I'm also not having any trouble hearing people around me, no muddy sounds behind the music.Fit is nice, I'm just using the default size. The soft silicone tips don't irritate my ears at all. I can shake my head pretty violently without them coming loose. I don't know how they'd do with really vigorous exercise, but I don't have a trampoline handy to test that. :)I've switched between normal and game mode a few times and things are just as smooth in as when out. I'm not a gamer so haven't got a good way to test the latency, but I expect that is as well handled as everything else.Definitely worth your time!
