Default Fommy 2.5mm to 3.5mm adapter - stay clear !

I bought a 2.5mm to 3.5mm adapter from fommy. co. uk (part number 7905) which specifically stated on their website that it was compatible with the Pearl. I was skeptical but decided to buy it - and not surprisingly when I tried it I found it wasn't compatible. It only worked on one side of the headphones and it kept triggering voice dialling.

I decided to open it up and modify it and would like to thank Woodsy for the info as well as the really helpful pinout info on pinout. ru

I replaced the internals with a piece of vero board with the required 1.4k resistor. At least the 4 pole 2.5mm plug and the 3.5mm adapter were useful.

So I now have an adapter for listening (I didn't want the mic function anyway).

When I told fommy that they were contravening the trades descriptions act when they said that their adapter does work with the Pearl they replied saying that it is compatible!!! implying I was lying or there was something wrong with my Pearl - strange that now I have modified the adapter it works perfectly with my Pearl !
