  Little known fact:  
Replacement batteries and accessories have the same performance standards as OEM batteries but are significantly cheaper. Why?
Because OEM manufacturers know they can get away with marking up prices 80% (and more) and people will still buy from them. Smart shoppers don't fall for that.

This replacement battery is 100% compatible with the Sony BP-HP550-11 and all Sony headphones that use this battery.

This is a specialty battery used in a remote headset which is either being charged or in use from 10 minute to 6 hour periods before being placed back in the charger. The warranty for the battery was one year and it lasted about 15 months (which is why it got 4 stars from me). I wish the battery had a little longer performance life to it. Even so it lasts longer than the OEM battery that came w
