Installed it and it works great, speaker sound great. Had to customize the speaker a bit to fit a 6D dirt bike helmet, but nonetheless, sounds fantastic. Hot Glue gun is the way to go for installation.
Upgraded from a cheap helmet intercom, the PCI setup works as expected with no issues so far
All components are high quality. Mic is clear and does not pick up background noise like cheaper headsets. Connectors will break away before breaking (when seperated from bike). Great product and service. Could be a little less expensive since it is built overseas.
The quality and construction on this kit is very good. Opted for the Kenwood style connector. All the plugs fit securely. The cables feel heavy duty, and appear to be molded especially for PCI, as their logo appears on the cable split/strain relief.
System integrates well into my Fox helmet. Speakers and mic seem to have good clarity.
If you don't want to permanently mount this system, you don't have to. The speakers stay in place with helmet padding, and the wires can be routed beneath the same. Boom mic mounts with a few zip ties on the lower portion of the face protector on my helmet.
I know people that have gone the cheap route on a helmet kit. They always fail quickly. Don't bother, this will be the only kit you'll ever need to buy.
