If I make a 2.5 mm to 3.5 mm adapter for
the plug, is it likely to work with a Sony
PSP?

Thanks, * * * * *... Peter E.

You would have to try it and see.
Note it is not a stereo device.

Thanks.

This is my hypothesis.
2.5 mm TRS plug on Samsung headset.
Sleeve = earphone - & casing of electret mic
Ring = mic
Tip = earphone +

3.5 mm socket in Sony PSP.
Sleeve = earphones - & casing of electret mic
Ring = mic
Ring = right earphone +
Tip = left earphone +

Any comments before I start soldering?
