MK136 Super Stereo Ear

This gizmo is exceptionally cool if you’ve got anyone interested in building and soldering their own projects such as this one requires. This is one of my favorites because it works so darn good, so you really get to see some results after your build. I give it 5 stars but it would be even better if they had a case to put it in, as it’s not as rugged as you may like it to be once you see how useful and exciting it is to put it to use and you start carrying it around. Without a case you just have to be mindful of the exposed components so they don’t become damaged or pushed off the board. For the price though this is by far one of the best DIY solder type projects that are out there. This is my second one. Also be careful not to output its source to itself so you don’t damage a microphone.

Liked this kit so much I bought 2. Fun to assemble, and nice to play with. Microphones are far from directional, so you can't be in a room with ANYTHING noise-making (e.g. fridge, heating pipes) or else all you will hear are your appliances. One issue is that the microphones are wired up in the opposite direction, so the left microphone feeds into your right eat and the right feeds into your left even if you put the kit together correctly.

Overall I found the kit fairly easy to build. Only the microphones provided a challenge. More so because I wanted to build a case to put it in to make it more practical to use outdoors. I found a video on Utube that suggested using screw terminal blocks, soldered to the board to mount the microphones. So I tried it and it works great. I found though I had to super glue the connectors to the board to keep from loosening the solder connections from the board. I later added a power connector so I can run it and a bluetooth transmitter off of a rechargable 5V battery battery pack. I retained the built in battery option. It works well this way and will run for a long time from the battery pack.

you get what you payed for... but is good soldering practice

First one came soaked in amonia. Returned it and ordered again. Second one i put together with no issues. It amplifies nothing and the little sound i do get on full blast, the sound quality is utter garbage

Great project, but also perfect for costuming. I wired the microphones into my Star Wars costume armor and have it set up with headphones that allow me to hear the outside world from inside my helmet.

This amplifies the background noise more than anything else. I can hear voices better without it.

This has been my training kit for soldering. Kids love it. I attached it to my robot tank and routed the headphone output on this to an FM transmitter (another good kit to try). Next I'll hook it to a pan/tilt rig so we can aim it. I didn't attach the microphones directly to the module, instead have them on some longer wires so I can move the 'ears' independently from the main unit.
