Hi guys,

Few days ago I read this discussion here:


And this part about AKG k340 electret phones is something interesting:

"his take was the charge would last 30 years.... Our own Rick has mentioned the possibility of recharging with a battery cell".


Any hi-fi wizards here could shed more lilght on this?
