The problem is the earpiece. The Mike works fine.I cut off the earpiece and spliced on a Koss sparkplug ear plug at amazon for less than $10. The splicing requires a bit of micro surgery but finished with shrinkable tubing it works fine. Youhave toi get used to inserting the plug in youear before you put on your helket and take care when removing your helmet.I am usingf it with my Zumo 55o. I listen to music traffic directions and I make and receive telephone calls. I just porchased the XM antenna from amason and I will be able to listen to XM music and get traffic and weather.I am now pleased.Another point.The Koss vomes with 4 ear plug cushions. Another 10 from Koss.com is [..] including shipping. The Koss has a lifetime guarantee.
