Review on THOKWOK Motorcycle Bluetooth Headset BT-S3 for Snowmobile Ski Intercom - 1000m Communication System, Helmet Headphones, Up to 3 Riders, Soft Microphone (Pack 1) by Adam Wilson

Installed on my TSG PASS helmet. The block works great. Low profile inside and out. I can listen to music while driving my EUC and still hear ambient noise. (Don't expect 5.1 Dolby Digital surround sound quality here.) These are regular speakers. So if you're looking for bass and treble, you'll be very disappointed. This is a basic setup that works well. You can listen to music and FM radio and answer calls. The microphone sounds good when making calls, and there is no complaint about wind noise. Which is VERY helpful. You no longer hear a soft beep when driving faster than 32 km/h. The beeps in your helmet are now loud and clear. I wish the sound quality was better but it works.
