Review on Wireless Bluetooth Headset Headphones for Motorcycle Helmet with Microphone and Sound System - Slim 0.27-inch Profile by Van Masterson

Good headset, I put it on my helmet and on my girlfriends. She couldn't hear me well on her bike, but I could hear her well in my headset during a call. Some strategic placement is required to support voice recognition on a call. I will also say that there is NO BASS in music. However, the volume is sufficient. I'll leave that with this helmet, but I'd probably advise paying a little more if you want something with better audio fidelity and music quality. Plus, these speakers are massive and will crush your head if you don't have a flip-up helmet.
