DECT standard domestic portable phones come with a 2.5mm jack which allows connection of a mono headset with mic. It's a standard socket - like 3.5mm, just 1mm smaller. So instead of being L/R, two of the "rings" would be "earpiece/mic".
All well and good except... it's very quite, both headset and mic for the person at the other end. We bought a second type. Still very quiet. We tried it on our neighbour's DECT phone. Still very quite.
So, the solutions are: Spend £90 on an amplified headset (not gonna happen!) or try a headset amp. So, my questions are:
1: If I bought a standard stereo headset amp like the £15 FiiO for example, using the appropriate 2.53.5mm converters of course, would this work for amplifying the mic input as well?
2: Better (and much preferred as a learning experience): As a beginning hobbyist just about able to solder onto protoboard, is there a simple "handful of passives and a battery pack" type of circuit I could construct and put in a box that would amplify both earpiece and mic?
Thanks!
