I like the concept of the Auvio headsets but have a "sweaty ear syndrome" issue with both models. The big, circumaural (around-the-ear) model is just too hot and uncomfortable in the summer. The earbud model is even more of an issue for me. I can't handle earbuds for long because they pop out of my ears when they get sweaty (unless I painfully cram them in); and, with this model, you have the additional weight of the receiver pulling on them. I know they wouldn't work for me. So I decided to cobble together a solution...
Someone here mentioned you can often find "as-is" (broken?) Auvio headsets on eBay. Often the issue is something mechanical, like a broken wire. I scored a pair for 5 bucks! The shipping cost me more than that ($6)! The set I got is like new, and worked fine except that right earbud had a bad connection inside the earbud itself. If you wiggled the cord, it would stop working. The earbud is sealed and can't be easily fixed.
No problem! I cut off both earbuds and wired the receiver to a set of lightweight, over-the-ear headphone I got with my old BH IV. Here is the result. The receiver hangs behind my head, just below collar level on my neck/back. and the receiver weight doesn't tug on my ears. They sound GREAT and work PERFECT for me... way better than some noisy, fm transmitter-based solutions I've seen.
Total cost, $11, not including the old headphones. I may eventually replace the cheapy phones with a higher quality set, I'll still stay with a similar featherweight set.
