Yu F. 3 We bought a set to use with our ski helmet. Initial workmanship looked ok and pairing had no problem. The 3M tape holds up just fine, but here are some issues.1. The volume of the system voice prompt CAN NOT be disabled or adjusted, it is so loud when the Intercom connection is disconnected (although the volume is acceptable when it says connected). I contacted the manufacturer, they claim this is as designed and can not be changed.2. The FX8 logo will keep flashing even when everything is connected, which is annoying.3. The FM function does not have auto scan, you need to manually cycle through all empty channels with white noises.***When I contacted the seller for my issues, they offered me a pair of mic and speaker, which will not resolve my issue, as such I don’t know what they are trying to achieve. Also after I posted my review, I received another email from the seller asking me to change my rating.Additional notes after using the com for about a week on my ski helmet.Good:1. Hold up fine in heavy snow (usage ~6 hours a day)2. Battery lasts full day of ridingBad:1. Distance never exceed 50 meters without any obstacles on a flat course, it will start to break up ~50 meters even with the antenna up.2. Huge wind noise if you ski over 40?km/h (which means most of the time)
