Mod: use M$ Wireless transmitter on Mixamp

[xavier_s37]

can u put out a tut on how you did this start to finish with a parts list and pictures? would be awesome if you could

Problem is Xav, I cant reopen it as its hotglued so no other pictures. Its super simple, you remove the headsets earpart, remove the two small screws, crack the thing open, cut the 4 wires of the mic and speaker as far as possible from the PCB. Cut the Mixamp mic cable on the controller side and connect it to the wireless headset like this:



If you dont want to charge the wireless headset you can replace the battery with a USB cable. To reduce the voltage you need to connect a diode to the + so the wireless does not heat up. Dunno the part number yet, waiting for trigger to tell. I used a Iphone wallsocket to USB converter, safer than connect to your xbox imo.

This is great. Any word on the resistor required for USB power?

[roads]

No he doesn’t know any more. Here are pics of the diode.

[Terminal]

What is the brand or numbering etc so i know exactly what im looking for.

[SILENT TRIGGER]

the diodes are named:
1N4004 Shottky Gleichrichter Diode

here a link:

So these are the same ones?

[SILENT TRIGGER]

yes these are the same

but you only need one, not 200^^

Just a little question:

Do I get some noise issue if I use the wired headset cable instead of the mixamp cable?

[SILENT TRIGGER]

yes my first mod was with the standart headset cable.. with these cable i have some noise in the backround if i speak.. you have the same nois if you use the standart wireless headset without mod.... the headset transmitter is not the best quality.. but it's the one and only transmitt on the market....

[xavier_s37]

roads by any chance you dont have pics of the diode connection to the usb do you?

[SILENT TRIGGER]

the diode must be connected to the positive pole.
The gray line must show to the headset.

Sorry hotglued in the device so no pic but just do it as Atze Trigger said. Better use a wallplug to USB converter like the Iphone uses to charge than a Xbox USB port.

Would the same resistor work if i was using a Microsoft wall socket charger for the headset instead of the USB one?

Hi

I did not make this mod yet, but I can say it will work with the charger.
Anyway the diode is there and its function is to reduce 0,7 Volts from the 5 Volts provided by the USB port.
With this you get 4.3 Volts on the headset, much better than 5, yet you will have 1.3 to 1.8 Volts of difference. If you can measure the current that passes the diode we can calculate the value of the resistor to get the remaining voltage on the resistor, else you can use two more diodes to remove 1.4 Volts from the headset.
Just like this ------|›|----------|›|-----------|›|----------   
Voltage        5V            4.3V           3.5V             2.8V                 

Hope this will help you out to solve the over voltage issue
Best regards
