ohhh.. i listen mine with tidal, wifi on and bluetooth off..and i didnt turn the wifi off while i sleep, maybe thats causing the battery drops more.. i notice that my hd800s didnt sound that good with kann player, dont know why, but feels like it hurting my ears even if i listening with low...

do you guys have issue with the battery draining so fast while not in use? im using my kann with hd800s and it drops from 100% to 90% (more than 30 minutes listening), and i unplug the headphone jack and go sleep.. check the battery drop to 70% in the morning(without playing any music at all)..
