Hi guys,

Few days ago I read this discussion here:

http://rockgrotto.proboards.com/thread/2554

 

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?

 

Cheers,
