Summary: If you can look past the failings of the Android app, the Samsung HM3700 is a useful and attractive mono-to-stereo Bluetooth headset.
Pros: The Samsung HM3700 Bluetooth Headset Kit is a compact mono-to-stereo convertible headset. It comes with a pair of stereo earbuds, and a 3.5mm jack adapter so you can use your own pair. Features include multipoint support, voice controls, and compatibility with Samsung's FreeSync Android app for additional functionality like text-to-speech for incoming messages. Sound quality is excellent.
Cons: The FreeSync Android app can sometimes cause the Samsung HM3700 to disconnect, and the text-to-speech feature is unsatisfactory. The HM3700 lacks music player controls.
