yeah I got this handsfree for my sony z710i,the device was horrible compared to the oem headphones that came with the phone. I lost reception on radio signal, and it was tempermental depending on how the wire would bend. Basicly it only lasted me 1 month worth of use. The only good thing about this handsfree set is the earbuds, much better than stock. I wouldn't recommend this to anyone,since it's poorly made.
