In conclusion, this is a very worthy attribute of your life, unless of course you will use it to the fullest - work, games, music, etc. I still compared the sound with my open ears HD 650 (well-known brand). And so HD 650 do not play so. Those. they play very well, and they are very worthy (and cheaper), but these ears play like that. Well, I already wrote everything above) It's probably better to have a separate device for each task, but I can't afford it) I needed versatile and high quality. And now, it makes me happy every day! The battery holds normally, about 5-6 hours of active use. Although today I have been listening for more than 7 hours, and so far they are working . If anyone is interested, write, I will try to answer questions) Good shopping and good mood everyone)))
