How long does the battery in your headset last? I fly often for 7h+, and with travel to/from airport, waiting etc, it can be more than 12.

Mine lasts about a week. I usually only use it for a few hours at a time, but it's never been a problem before. It charges way faster than it discharges.

I'm using the TT-BA08 dongle and it gets about 20h of battery life - substantially more than any Bluetooth headphones I've seen (and Etymotic don't make any AFAIK.)
