Cheap price not as good as other headsets but they do work . Calls are good not great so listen to music not so good but dobthevjob for last result. But other headsets do a better jobI almost lost this while in the store. better for people with larger ears.It a nice earpiece and it fits perfect over the ear and it pretty loud when playing the music really coolI love how it fits over the ear and not inside.This earphone works… but it’s not bone conduction. It is a speaker that sits outside your ear. I have some Shokz that use real bone conduction technology and this is not even close. It’s not flexible and does not conform to your ear. It does function, and provides sound, but the volume and quality are very poor because of its small size. It will work if you have nothing else to use.The audio is very low, even when the volume is all the way up. The room must be very quiet to hear anything. It is light weight and fit well on my ear but, what’s the point if you can’t hear anything. It is NOT worth it.No volume controlSound isn't audible enough for being anywhere except a quiet room, in my experience.Doesn't sit well, especially with glasses.How it is shaped. The opening for the speaker doesn't point into the cochlear shape of the ear either so Sound vibration is being primarily away from the ear canal. When you do get is the vibration being sent through the plastic cover itself.1star for functioning almost exclusively in quiet places.volume only adjust by phone connection. kills phone battery fasssssst
