B-TechUniversal 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

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.

Allowed me to connect a standard pair of in ear head phones but keep a PTT pressure switch. Not as good as the professional equivalent but about 15% of the price.

Needed this for automotive use of a radio. Used my Aux port and a 3.5mm cable, works great!

Works great on the earphone side. But note it expects the input to have both mic and phone, in which case the PTT will work. But if you only have headphones, not a headset, this doesn't include a microphone (only a PTT), so you're "listen only". I might have been able to figure this out by reading more carefully before buying, but it wasn't obvious.I was also able to use this, plus a 3.5mm audio cord and a $5 USB sound card, to get audio into fldigi, which should allow me to do digital modes - at least RX. TX would need a splitter, and a PTT solution or VOX.

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.
