What's better than a retractable and durable stand firmly that holds your iPad and iPhone at a comfortable viewing angle? Nothing! The built-in 3.5mm inlet supports surround sound signals on the highest level. The Coby CSBT-307-SLV supports any kind of media playback: music, games, movies or net-based media streaming. The built-in microphone is ideal for clear conversations -answer and end calls with only one button. Even a high sound frequency guarantees crystal-clear sounds and two robust rubber feet at the bottom of the stand to help reduce sound vibration.
