Anyone having problems with the looser connection on your Westone earpieces (it sometimes causes the sound to cut out when you move your head around... the cable connector will sometimes get cocked at an angle enough to apparently intermittently lose connection)...
I purchased this pack of little
rubber o-rings. They fit perfectly over the fitting on the earpiece. Just slide them on, over the earpiece connector carefully, then attach the cable. It keeps the cable's connector more firmly connected at a straight angle, without the gap, and keeps the connector making contact much better. I had the problem from time to time, but have not had it at all since I started using 'em. It also will keep the earpieces from rotating so loosely. And there's enough in the pack for a lifetime of Westone IEM upgrades.
