Telephone Pick-Up Coil with Suction Cup, Features: Record Telephone Conversations on Any Tape Recorder with a 3.5 mm Microphone

The Samar 3.5mm Telephone Pick-Up Coil Microphone is an excellent value. I use it to capture electromagnetic sound fields for music production with my ZOOM H6 recorder. It works perfectly with a 1.5m adapter and picks up fascinating rhythms from household appliances like microwaves and washing machines. A solid, budget-friendly tool for audio creators. connectivity is pi to use

Does not work on Cell Phones but gives crystal clear recordings on Landlines.

Doesn't work in my recorder

Works well

it does work, but will be pretty useless unless your recording device has a good amplifier in it. fun to put near electronic devices to hear them think, or to record sounds from devices where disassembly is not desired or possible

This mic would not work on our phone’s receiver due to the texture of the phone’s material. I feel the phone needs to have a very smooth surface for the suction to work. I have to use a rubber band to secure the mic to the receiver. The mic does pick up the sound and works well for the price.

Connected to my voice recorder, im able to record phone calls privately, and being that im in a single party state. I love this!

My kid has one of those toy-review YouTube channels, and he uses this device to get clear audio off the toys he reviews, without the distortion or room noise/reverb he might get through the mic on his camera. It works great for that, fwiw!
