Looks very cool. Very convenient charging via USB port. Not so good sound quality. Audio has a lot of static tics and pops and that is the only reason I give this 2 stars. Everything else is great.Pairs quickly with my Nextel i870.I lost my Plantronics 510, so will fall back to this unit until I can find the latest earpiece that has received good reviews. Other may have a great experience with this earpiece. Unfortunately, I am not one of them. Maybe I got a "bad" one.
