This gives me some inspiration for my ‘mini’ studio! I mostly lurk on KVR too, but this might get me posting more.

Gives me good Inspiration

I thought, why not solder a 3.5mm trrs plug onto an old telephone receiver, and yep, it works! Got a very retro handheld "headset" for laptop or phone, in glorious mono.

That phone receiver looks fabulous! Very cool.

Looks good. I have a bunch of cheap phone mic elements off AliExpress, with a couple soldered up 'bare', but not a whole handset.

The speaker is somewhat soft, but the mic is obnoxiously loud. Easy fix (todo) two resistors.

I first had the speaker connected only to tip (left)
Phones understand an unconnected right speaker (or unexpected high impedance of left) as: the volume up button is being pressed.
Seems as, now tip+ring both are connected together, the volume is better.

Thanks for sharing the details! That makes a lot of sense about the speaker and mic levels, connecting tip and ring together is a neat workaround for the volume issue. I also like the “resistance is futile” nod, made me chuckle. Curious, when you get around to adding those resistors, do you have a plan for specific values to balance the mic and speaker, or are you just going to experiment?

Very cool high tech.

Thanks everyone, this topic is loaded with cool projects. Inspiring me to get my workshop out of storage.

Simple but strange gizmo...
