Review on 🎧 Yideng BT-S3 Bluetooth Headset: Full-Duplex Intercom System for Motorcycle Helmets - Crystal Clear Communication up to 1000m, Ideal for Motorbike/Ski Helmet, 3 Riders (1 Pack) by Matt Dyen

Battery life is great, I've had it for over 2 months and haven't charged it yet. I used this system before I had an exhaust and it was great. I have to say, if you have a loud racing exhaust, you probably won't hear the callers when you're over 60 mph. Callers can still hear you. The microphone is excellent, nobody complains that they can hear me. All in all, this is a great system. Music can still be heard at high speeds and the sound quality is pretty good for a budget system. Costs money
