Hi folks,
I've not posted here in a long while and have a question about the Total Bithead.
When it's plugged into the PC via USB do I need the AAA batteries?
I want to buy one for work as I'm fed up of being able to identify different Windows apps from the sound the make on my UM-2s

It's likely always going to be plugged into the PC.
Will I still need batteries or can it be completely powered from USB? From reading various stuff I'm not 100% clear?
Cheers
Paul.
