These were given to me. The design is a good idea that unfortunately does not work at all well in practice. There is too much sound leakage in and out, the drivers do not fit next to the ear snug enough to provide any measure of seal. They cannot be used for serious listening due to this fault and therefore one can only hear the high frequencies mostly. Sorry but these only merit a 2 out of 5.
