Since many Sony headsets use the BP-HP550-11 battery pack, I assume your battery pack is the same. If not, I assume whatever battery pack your headset came with, it is some type of plastic holder that holds two batteries together. Even though you can use regular AAA batteries (that you would have to replace often), there is a huge convenience factor with using the charging cradle that comes with the Sony headset. A solution I found was that I ordered some 550 mAh AAA batteries through Ebay (they came from England and cost me $8 total for four batteries). To make them work in the Sony headset you MUST use the bottom part of the plastic battery holder piece (all you need to do is peel off the BP-HP550-11 label and the bottom half of the plastic battery holder piece slips off of the Sony batteries). Then just slip in the new AAA batteries into the plastic battery holder bottom and then insert into the headset. The reason why you must use the bottom of the battery holder plastic piece is because the plastic piece pushes on a little switch. This switch activates the charging mechanism to enable the cradle charger to charge the batteries.

NOTE: I am not an electronics expert so I do not know if there would be any problem using other rechargeable AAA batteries (with higher mAh ratings). So I decided to be safe than sorry and ordered the 550 mAh batteries through Ebay.
