Review: No problems and HD speakers work well. - The clamp kit worked great on my extra helmet
Review: Good replacement set for exising headset - This product works well. It replaced the mic/speakers for my existing Sena 20S. One of my speakers was flaking out and the mike boom had become weak and started drooping. The speakers are a little smaller in diamater than the originals, but they work well. Replacement in the helmet was straight-forward and the headset clipped right on to the mount as expected. Works like new.

### ⭐⭐⭐⭐⭐ Perfect replacement unit for your Sena
*by E***R on November 28, 2023*

Now this is exactly what a replacement base unit should be. My. Wires were worn and I had a hard time understanding what someone would say, so I decided to go with this Unit. Not only do I hear clearly now what someone is saying but the quality of the sound is so much more improved over the old one. And it fits perfectly and you have choice how you would like to configure your helmet, boom mike loose or attached to inside or a simple button microphone if you have a enclosed helmet. Enjoy the music and be safe on the streets.
