Sound quality is pretty good. The strange loop is somewhat unnecessary for "normal" use. You should buy it only if you explicitly use has for this. Oh, and these announcements and the blue flashing light (you can possibly via glue) are a bit annoying.
The reason for 2 stars: the description is something of a good quality of the microphone: I can not confirm - the quality is really bad, noisy, tinny and quiet.
