One matter that I think should be considered is the frequency profile of one's hearing loss. A bluetooth headphone set will not normally provide for the frequency compensation that your audiologist has built into your hearing aids. Putting a headphone set over the top of hearing aids will generally result in feedback howling. An in-ear bluetooth headphone can be very comfortable, but with hearing aids removed, will not provide frequency compensation unless you add a filter circuit between the audio signal and the bluetooth transmitter.
If your hearing aids are bluetooth enabled, then for a few dollars, you can buy a bluetooth transmitter that plugs into any audio output. The transmitter battery is re-charged from a USB port on a computer. Hope this helps 73 Kevin VK3DAP / ZL2DAP On 24/01/2011 6:15 PM, Dave Sergeant wrote: > On 24 Jan 2011 at 12:46, Max Kempson wrote: > >> After many decades of Ham Radio (licenced 1953) my ears are showing lack >> of sensitivity and signal to noise!
