I’ll be honest and say I have never been a fan of Bluetooth stereo headphones but Motorola’s S305 has recently made me a fan. All of you active people out there can put these headphones to good use. I desperately wanted to buy a pair of bluetooth stereo headphones with a gift certificate I won at work. The motorola S9 HD sounds great, but the design is so flawed that I just had to return it. The Cardo S-2 Bluetooth stereo headphones has a fantastic sound quality not easily found in Bluetooth stereo headphones and is surprisingly light. The controls on the Cardo S-2 Bluetooth stereo headphones are very user friendly and I found them easily accessible.
