"Great value and very versatile."4.5 starson by nozmo_king
Pros: This is the first Bluetooth hands-free device I've owned that people haven't complained about not being able to hear me during phone calls. The audio quality for calls is crisp and has none of the "warble" as with other Samsung devices.
Cons: The included micro-USB to 3.5mm adapter is a bit long and males the device a little cumbersome.
Summary: The HM3700 is a great universal USB solution for smartphones with multimedia applications. No one I've called or talked to while using it as a stand-alone hands-free headset has even asked if I am using a Bluetooth device or complained about not being able to hear me like with other devices I've used. The included stereo ear-buds sound almost as good as my Koss and Sony buds and have conveniently shorter leads and built-in auxiliary microphone. The Bluetooth range is also very good and far exceeds the manufacturer's rating with no dead zones or drop-outs. All things considered, the HM3700 is a great value.
