Eartec Simultalk 24G Replacement Master Radio

We use this for dressage lessons. When an older one failed, my trainer and I tried using bluetooth earpieces with our smartphones instead, but this is just way better. The bluetooth earpieces would get finicky and start going into battery-saving mode (losing audio) mid-lesson, and the call would get dropped when someone would receive an e-mail or a text message. It just made us appreciate this product all the more. Very clear transmission of sound, earpieces stay stable throughout a 45 minute ride with canter and trot. Like everyone else says, the little plastic clip is totally insufficient -- I put the whole remote in an iPhone 6 armband holder instead. I won't give this product 5 stars, though, because the older remote my trainer had died within 1 year -- this was just after the 6 month warranty expired. That's a pretty lame warranty for something so expensive.
