  3. 3-contact 2.5mm male - 4-contact 3.5 mm female

3-contact 2.5mm male - 4-contact 3.5 mm female

I got an Iphone headset which has four contacs on a phone plug. But the phone uses a normal 3-contact universal handsfree.

I have bought numerous adaptors but they don't seem to work. I can hear the phone, but I can't be heard.

I am now tempted to make the adaptors myself. How do you spec them? Would places like Mouser have them or are they still too new?

Slightly wrong. A 3 contact 3.5mm plug can be used for earphones only, but if you want a microphone, you'll need the 4th connection (nearest the plug).

This should help:

How about buying a headset that fits instead of spending money on numerous adaptors?

What color is your phone? How heavy is it? Does the IMEI end with a C or a Z?

Have you considered getting a new phone? I was trying to make a four-pin handset work on a three-pin cell phone around the time I decided to switch to another provider. The phone that came with the change had a four-pin jack, and everything worked fine.
