I have had the Eartec headsets for one season and they work great - no issues.  A friend of mine has had them for 3 years - again, no issues.  The only draw back is that you have to remove the batteries every time you put them away, but no big deal.  https://www.amazon.com/Eartec-UltraLITE-Wireless-Microphone-Headsets/dp/B01LOKU8KQ/ref=sr_1_16?crid=1BFQFWXIPGZR3&keywords=hands+free+communication+wireless+headset&qid=1552052951&s=gateway&sprefix=hands+free+communications+headsets%2Caps%2C221&sr=8-16#customerReviews
