These have a very good sound. I tried them on my computer and my phone. I called and left a message on my land line and the microphone performed just fine. They were as comfortable as my much more expensive headphones are, which sadly isn't all that comfortable. I frankly prefer ear buds but you do seem to get better sound out of this style. The switch or microphone on the line is a bit obscure. There was zero documentation so I pushed it, I guess that cut out the microphone, I wasn't 100% sure. I would like a clearly labelled off or on and gasp maybe even some documentation. However I suspect that old guys are not their target market and the kids probably have had this kind of switch on their gaming devices. I liked the sound but am not keen on zero documentation.
