    TLDR: It's not worth the money at all, only get it if you have something very specific in mind like I did, wanting it to be flush with the helmet for aerodynamics. If I didn't have the rpha91, I would have gotten something much more affordable.

    Very mediocre sound out of the box, maybe it can be improved with some equalizer if I find something because so far I haven't, as its own app only supports the more expensive models. As for operation, also mediocre, you have to memorize how many times to press plus or minus to navigate its menu, for example to connect with another intercom device from a different company.

    The sound is wonderful, it has a lot of bass, it has a mobile app but also a computer app and I can listen to music even at 120km with the wind hitting the helmet, compared to another one I had where after 100km I couldn't hear anything. It's worth its money

    Wonderful product. It does what you bought it for. I forget to charge it. It works perfectly with Sena 5Rlite without disconnections.
