Review on 🎧 HuanGou BT-S3 Motorcycle Bluetooth Headset with 1000M Helmet Intercom - Perfect for Handsfree Communication, Music Streaming, GPS Navigation & More! by Justin Guldin

TLDR: Does the job well for the price. The longevity of the device made me buy a different brand for my main device. You don't have to replace something like this every year. I bought two packages for communication when riding a motorcycle off-road. The phone's Bluetooth function is good, you can make calls and listen to music. The speakers were sufficient. Clear audio when communicating internally with another device. Line of sight is very important when you need range. Always seemed to have some connection issues, had to turn off Bluetooth on phone before connecting two intercom devices and always seemed to have to reset the device when connecting two intercom devices (regardless of whether connecting to the same or a manufactured by another device). A year later, the intercom function stopped working. Possibly due to battery life issues? I contacted the seller and he sent a replacement despite the 1 year warranty had expired - thanks for that.
