this be a excellent quality item . the sound be crisp and balanced as well as provide clearer bass response than any headset I have try . I listen to a vast selection of music type from baroque to hard rock . the only real let down be the ear hook . I find they to be useless but that could be just I . still , that be not a deal breaker . despite what they say , the cord will still tangle . however , they be a lot easier to untangle . I find that I need to use much smaller ear bud -lrb- the rubber bit -rrb- than I have with other headset . compare to other headset , the the ear piece be much longer . the ear piece tend to fall out unless I do that . not a problem , just a difference .
