Another of my 2 cents on this topic... While not for transmitting, there is a worthy consideration for wireless Rx headphones, the Gray Ghost headsets I use for metal detecting. There is a 1/4" plug which goes to the radio & is the transmitter. The headphones pick up this Tx and reproduce the sound.
Both the headphones and transmitter do require being charged, this may be a deal breaker for some. My Minelab CTX3030 detector offers some 50 tones in the discovery process and they sound beautiful with this headset. They are mono with very low latency, when swinging the detector, even a little delay is unacceptable and would give incorrect info, so I expect the response would be the same for our needs. I got my set from here: http://www.colonialmetaldetectors.com/gray -ghost-wireless-fbs.html Just google for Gray Ghost headphones. 73, Gary KA1J > I used to design aircraft audio systems for a living, but have been > retired a year.
