Poor sound quality lacking in anything remotely bass heavy like some reviews have reported. After trying every combination of ear buds and hooks I could not find a combination where these headphones would stay in my ears. The wire connecting the two ear buds is too short and the inline controls are functional but usually caused the headphone to come loose when used. I had high expectations for these to be a viable replace for my Jabra Halo 2 headset but that is superior in ever way (and much more affordable too). These headphones have now been consigned to the cupboard of tech that has no viable use.
