Howdy,

I use a Siemens S46 phone. As you may know, it has a proprietary
earphone jack rather than the industry standard 2.5mm type.

I asked around and learned that an adaptor was available. I bought two
of them on the web. Neither work. They each have the same problems: It
is extremely difficult to insert the 2.5 mm jack, and once that is
done, I can hear nothing at all over the earphone. If, instead, I
insert the jack about half way, I can hear the signal, but at nowhere
near a usable volume.

And so this question:

Might you know of a source for this adaptor that will actually work?

Very sincere thanks,
