📞 Vnetphone V8 BT 3.0 Bluetooth Intercom with Waterproof Helmet Interphone Headset - Connects up to 5 Riders within 1200M for Wireless Communication, Walkie Talkie, MP3/GPS & FM Compatibility Review

Excellent clear sound, I can't even say that the volume of the voice on the bike is good at medium speeds on the highway. The only negative is the volume. The music was pretty quiet

Works great! Sounds crystal clear while driving. Easy to use. I was skeptical at first but after some use I was very surprised. So far, so good!

works well but if you have loud whistling you can use the speakers to get as snug as possible in your ears. I haven't tested driver functions for drivers yet.

looks and feels really solid. Easy to install and set up. Clear and clear voice sound when calling. The speakers are not bad, but produce a theatrical echo effect. The better the sound you play, the better it will sound, but by default the sound isn't as full.
