This headset works pretty well with good noise canceling, but it won't stay attached to my ear so the part that rests on my face loses contact.  At most it will stay on my head for 10 minutes. I find myself repeatedly twisting the thing back into place.  The second one I got (the first was missing parts) came apart when I tried to unplug it from the charging cable. Jawbone does not seem to offer any other buds (not even spares) so I just ordered some Acoustibuds in the hope that I can actually use it. If they don't work I will try a hack I saw with a Jabra eargels product - that involves cutting up the supplied earbuds and gluing the eargels to the locking piece. I will update this review once I get it to work (or not)
