I got this headset from BargainCell very fast, and they fit my A707 phone just fine. They sound good, but the design is a bit strange. They don't stay in my ear if I walk around, they just fall out. And it's strange to have the left side with such a short cord and the right side so long. But I got them because of the connection for the Samsung phone, and because others said getting the 3.5mm adapter causes popping sounds. I heard no popping with these.
