Review on 🎧 2 Pack EJEAS V4 Bluetooth Motorcycle Helmet Headset Intercom - Waterproof IP65, 4 Riders Talking Simultaneously, 1500m Talking Range, GPS Hands-Free, Stereo Music by Noah Warneking

Bought for 4 people so they can communicate with each other. Their synchronization is terrible, even with video. Once you turn them off, it will be awful to sync them again. As in a microphone, a piercing squeak can be heard constantly. You have to stay about 75 meters apart or you will become static and everyone will shut down. Once synced, they work well as long as you stay around. You can communicate normally with 4 people. Batteries last 6-8 hours on a full charge. I absolutely HATE the box they came in (see first picture). You pull out the plastic tray and everything underneath falls out. TERRIBLE! We have 2 other v6 kits that came in a different box (see second picture). They are amazing! SAVE and prevent them from breaking when hit or dropped.
