I'm with you, bro! I'd love a pair of good wireless, no-lag phones, especially if they were behind the neck so I could wear a hat w/brim.
I had the Auvio 33-283 buds, not bad, but they died. For now, I have gone back to wired. I bought a pair of Polk Audio Ultra Fit 2000's - I also added a coiled extension, because the Polks just have a 4' flat kevlar cord (which is excellent, same as the Klipsch S4 buds (love 'em!). I just hook the coiled extension to a clip on my tool belt and I'm good to go. (p.s. - I got some mfg refurbs for half price on ebay- perfect).
The garrett audio adapter has a weak soldered connection, so make sure it doesn't get snagged. The second time mine died, I dissected it and soldered together right and epoxied (JB Weld Marine) the fitting. If it gives again, I'll eat it! I also add some additional strain relief with multiple lengths of heat shrink tubing and / or magic (self-sealing) tape.
Love to hear about a great new wireless set if anyone finds one! (Forget anything Bluetooth, even the latest generation have a BIG lag issue).
