BTECH Universal 2-Pin K1 to 3.5mm Audio Adapter with One-Touch PTT – Premium Compatibility with BaoFeng, Kenwood Radios & 3.5mm Headsets with in-Line Mics

Works great with headphones plus microphone. Audio comes out of both left and right- mono as one would expect. Unfortunately, I cannot get it to work with M1 to K1 adapter. If your radio is BTECH k1 it will work well.

LUV it, this works GREAT with my headset

Very promising. My wife and I use our Baofeng BF-F8 radios at IndyCar races to listen to the track audio feed. We found that the Baofeng OEM earphones that came with the radios had terrible, badly distorted, audio. This adapter allows us to use our iPhone earbuds, and the audio quality is noticeable better. We found that gaming headsets also work, but do not provide the hearing protection we need. So we will wear 3M industrial ear defenders over our earbuds. We'll be at the next race in a few weeks; that will be the real test. One challenge that is still to be addressed is where to stash the extra long coiled PTT cable when it's not in use.

Haven't had the chance to use other than setting up and listening. The pins fit fine, just be sure to push hard to get them properly seated. Used with a set of mic'ed ear buds and sound quality was good. Other mentioned and can confirm, there is a loud electric popping when you power up but it doesn't seem to occur other then power on.

I have an Import Sport hearing protection which has an audio input. Works for iPhone, whatever. Ive been looking for the right setup to get it to work for me as a headset for Paintball. This plus a Headphone Audio Cable with Mic Boom cable did the trick. I have looked forever for the right combination to be able to use the hearing protection with it (also enhances sound). Contemplated throat mics but only one I found offered 3.5mm jack and it was not a trustworthy site and didnt appear to offer good pickup. Tons of other mics out there but none offered the right outputs and I dont solder.https://smile.amazon.com/gp/product/B0758RJ56Z/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1I was also able to readily hookup an old Xbox headset with mic. I was also able to get that plus the Impact Sport to work using a headset Y but that left me with another speaker. I guess I could tear it apart and remove the speaker. Also able to get another mic (that also still had speakers) to work by using a headset splitter to mic and audio going through the other headset Y. But neither of those two were ideal with the Impact Sport. If I just wanted the Xbox mic that would have been fine, but in the woods with paint and potentially rain I didnt want to chance it. Still a good alternative for general use hiking or something.I swear, Ive researched for days over the course of years to find the right setup. I cant speak to its ruggedness. I can say out of the bag with the right connections its working just as I hoped.

Used this to outfit my skid steer and excavator so the operators can talk easily while working

I ordered two, & only 1 came. Also, that one didnt even work.

This is a super discreet way to use your two-way radio in public. With the radio under a coat and a normal pair of earbuds with a microphone you look no different than anyone else listening to their music.Using the PTT allows you to transmit with the inline microphone of your ear buds. This is an ingenious accessory that is well built and easy to use.NOTE: you need ear buds that include a microphone for this unit to work correctly.
