I have some made by Radians. They are relatively inexpensive and work VERY well for me. I have the headset style and the hearing aid (think Walkers Game Ear) both made by Radians and I like them both. The headset type also allows me to use an earbud so I can talk on the radio (just run the wire under the muff) and I find them to be less annoying over hours of use when hunting. I got them for $125 and the hearing aid type for about $50 (set of 2) on eBay.
Still happily answering to the call-sign Peetza.
