Hi
I've modified my Orginal handsfree to give a 3.5 mm Stereo socket. This is the procedure:
1. Open volume control & mic holder from edges.
2. You'll find four wires to earphone on out terminal soldered to PCB.
duly marked R & L on sides and two common in the middle.
3. Remove the earphone wires. Fix these wires to a standard 3.5 mm Stereo Plug.
4. next get a cheap 2.5 mm to 3.5 mm converter which is available in India at no more than Rs.70.00.
5. We require 3.5 mm socket with housing from this converter. Take out the converter remove all connections.
6. Take a piece of 4 wire ribbon wire.
7. Connect as per drawing attached. 2 wires to middle terminal on original
housing --- to common terminal in 3.5 mm socket
one to L other to R terminal on main housing and to L & R terminal
on converter
Your unit is ready.
I'm using in with Sandisk in-ear plugs stereo headphone kit and works
fine . Mic also works so you can talk on phone and use it to listen music also.
