We ordered helmets with series 465 headsets installed from J&M. We ride a 2014 RT. We tried them on a trip from Texas to Colorado and found we could only understand each other about 20 percent of the time. They worked fine if we were at least four feet apart but had terrible echoes and distortion when on the RT. We called J&M on the trip and did everything they suggested but nothing helped. We returned the units, and J&M said they checked out fine but would send new units. The new units had the exact same problems. I asked to return the units for credit and just keep the helmets, but was told it was past the time allowed for return. Now I will have to pay for new units from another manufacturer.
