I have an old pair of wireless xbox 360 headphones that died and couldn't repair due to micro circuitry of turtle beaches, however I want to eventually make them wireless with an stereo fm transmitter and receiver. one question I have is how would I drive the voice chat and game audio simultaneously or near it on one pair of speakers? Would I create a summing circuit on the amplifier's input?

 

The first thing that comes to mind is a summing amplifier.

"turtle beaches" ?

 

"turtle beaches" ?

Is a manufacturer name...

 

I probably should have stated amplifier instead of circuit. I am trying to see what all kinds of op amps I have in bin is there any that I may need to keep an eye out for, also is there any ics that would be good solutions?

 

LM386 can make a watt (or 2) of power into 8 ohms. Most op-amps can't do that.
LM741 is antique garbage. Best used for filling trash cans.
Anything else, look them up.

I have a few lm386 ics and lm358 op amps so far I don't use my 741s I appreciate the help. Trying to find possibly a soc for the FM tuning part, right now I am doing block diagram and parts assessment.

 

I measured the headset speakers and they are 32 ohms each

 

I may see if I have any 8 or 4 ohm speakers that can fit in the housing.

 

one solution I found for the fm tuning part could be the TEA5767 FM Radio Module here . I already have an off the shelf transmitter so no problem there.
