Good value for the price paid.
Installation in the helmet is really easy, velcro straps and 3m pads are in the box with the instructions to follow.
Fast bluetooth pairing with the phone and between both devices, audio seems good quality and volume while not driving is high, in fact i can’t hear people outside the helmet.
I need to test volume while driving in the highway but i don’t think there will be problems hearing music or microphones.

I am writing from my wife’s town, about 100km from my house. I have to say that the intercoms are damn amazing. I have an Africa Twin and at speeds of 130/140 it sounds better than talking at home. We’ve gone through highway areas and desert areas and they work perfectly and you can hear a lot (I’m a bit deaf and I had to turn down the volume…). The only thing I ask is that the interconnection between intercoms and sharing music while talking could be easier… I know this is general, not just these but could you make it simpler. Otherwise, everything is great and I would buy from you again, honestly.

I haven’t tested the headsets themselves at a distance, but I connected four radios into one network, and the sound is good. I don’t yet understand how a conversation between four people will work simultaneously, but the speaker’s voice is heard clearly. This generation of headsets has a more voluminous sound compared to the previous one, but these headsets also pair with Lexin GTX. In the fall, I tried connecting three headsets: B4FM and GTX – they work. At the end of the season, I’ll update the review if I have the chance and I won’t forget.

I use the device for talking and listening to music. I haven’t tried communicating with other similar devices. The quality of the calls for me is very good. I had a conversation at about 120 km/h, and the other party said there was no interference or wind noise, and it was heard clearly and cleanly. Regarding music, I would say that it lacks a bit of bass. My motorcycle is a BMW R1200GS, the helmet is a Nolan N80-8, and it’s not one of the quietest.
