Ive had four bluetooth earpieces and This one fits very comfortable and is the the loudest one Ive used yet. Its good if you have a hearing problem. I drive alot and have alot of road noise. The only problem is your voice is not clear for the other person your talking to. It is distorted and people will ask you several times what you said. The best one Ive used yet is the plantronics 925 even though I'm not 100% satisfied about the way it fits in my ear it is very tolerable and It cancels background noise out very well. I like it alot better than the jawbone. The jawbone is huge and I cant turn the volume up loud enough to hear because it dont go far enough in my ear.
