I took a chance on this new product because I always wanted something that could be installed inside the helmet. Something clean. Installation was easy literally just followed the instructions and fit everything in the helmet. I made sure it didn’t get in my way or felt uncomfortable. Music sounded amazing! The music quality is way better than I expected and it’s louder than other helmet comm kits. Overall super impressed and recommend!

works great in the helmet after installation, will see how it will work on a long run. Sound quality comparable to good full size headset, very loud. Installation is very easy , just followed the instructions and watched the video. Does anybody know if I can charge BMT module with generic “USB-C to 3.5 mm” cable from Amazon?

The sound is very correct compared to Sena (arman kardon) and Cardo (jbl). Iasus X4sound is the first for me.
@Andey or someone else, have you got an answer ? We can charge BMH module with generic “USB-C to 3.5 mm” cable from Amazon?
Thanks,

Hi Julien and Andrey,
Thank you very much for the feedback! We’re glad to hear you’re enjoying the sound quality and overall setup. We really appreciate you sharing your experience.
Regarding charging, we recommend using our IASUS USB-C to 3.5 mm charging cable. While some generic “USB-C to 3.5 mm” cables from Amazon may look similar, many are designed specifically for audio output (DAC cables) and do not support charging or the correct pin configuration required by the BMH/BMT modules. Using those cables may result in the device not charging at all.
To ensure proper charging and avoid any issues, it’s best to use our supplied cable or a verified accessory from us.
If you have any other questions, feel free to reach out.
Regards,
Chelsea
