Hi - picked up a pair of sennheiser HDR120 phones at a thrift store, but no transmitter. My knowledge of eletronics is as such: black/green is usually earth and red positive, and soldering on a live wire causes a small explosion in your face.
Now onto the question.. is it possible to use a generic FM transmitter in the same frequency/range? The original unit takes a power and audio cable and transmits what I believe is a FM signal. The phones have a tune button and here are the specs of the transmitter:

Technical Data – TR 120 Transmitter
Carrier frequencies
..........................
863 MHz variant: 863.3 MHz,
864.0 MHz, 864.7 MHz,
926 MHz variant: 926.1 MHz, 926.8 MHz, 927.5 MHz
Range .................................................................up to approx. 100 m
Modulation........................................................................... FM stereo
Signal-to-noise ratio
........................................................... > 65 dBA
Could I get a cheapo FM transmitter with an overlapping range and tune in? I will be sitting VERY close to it (max 9 ft)..
tx in advance!
