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.
Review: No problems and HD speakers work well. - The clamp kit worked great on my extra helmet

### ⭐⭐⭐⭐⭐ Good replacement set for exising headset
*by C***H on December 4, 2024*

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.

### ⭐⭐⭐⭐⭐ No problems and HD speakers work well.

The clamp kit worked great on my extra helmet

### ⭐⭐⭐⭐⭐ Despite Being, Um, "Lautsprecher," Allowed Me To Move my Sena to a 2nd Helmet
*by Z***Z on June 29, 2022*

Insofar as I can tell this is a genuine Sena product. This is a complete accessory kit that appears identical to what came with my 20S Evo originally, including the mounting base (very important) and entirely too many sticky velcro pads, self adhesive mounting strips, microphone options, little foam mic wind socks, and so forth. Assembly works exactly like the parts that came with your Sena unit originally. I used this kit to add my Sena's functionality to my second helmet, in this case a dirt bike helmet that I use for off-road riding. It'd be nice if there were an option to buy JUST the mounting base, I guess. I didn't need 90% of the extra speakers, mics, and all their associated accoutrements.
