These are ok, nothing special. The sound isnt all that impressive when listening to the radio, lots of static! Its a slow and annoying process to select a new station & taking a call on this device is not as convenient as it should be! When someone calls you, you need to select from 3 options on your mobile phone each time and then wait on a pause before your caller hears your voice! The 3 stars are for the quick & easy pairing of devices & the strong earphones & clip which attaches the device to your clothing.
