I used three, and its quite solid on my wall. I use them on my golf cart and they get rattled around a lot but still working great. x1d ii This really solves the issue, and looms very nice doing it. I hate headsets that squeeze the head. x1d ii Quality was better than expected. x1d ii This was very easy to build and comes with all the parts/tools needed to build. I can comfortably wear a moderately warm sweater underneath. The remotes are easy to use and you can use any remote with any unit so that is nice. x1d ii The pair I initially received was damaged (no fuss exchange for those), but were so much more comfortable in the heel area than the first pair. TORTURE!
