I like the product as I have to have it to be able to hear the other person -- I havea 12-year old Nokia cellphone and holding it up to my ear is useless... it has tohave an earbud... It does not get 5 stars because (while it works fine), the wire isso fragile that every 2-3 years it breaks and I have to reorder. in addition it will notstay in my ear as is, it has to have an adapter piece that I get from Radio Shack.But the sound quality that it does transmit is first class.
