Review: works as promised - Grade A - works as promised - adds a capability to the Baofeng DM-32UV Review: Finally the right setup for my shooting protection - 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.desertcart.com/gp/product/B0758RJ56Z/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 I 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. ## Features - 🎧 Universal Compatibility: Transform your 2-Pin BaoFeng, Kenwood, and similar radios to connect with any standard 3.5mm headset or audio output. - 🎤 In-Line Mic Support: Utilize your headset's built-in microphone for seamless two-way communication.

It comes with a reversing cable for ground on shield **Q: Will this work with a TYT md380u dogital radio?** A: No will not work with any radio because PTT button does not work **Q: Can't get it to work with Apple Earbuds with 3.5 mm jack? Is there a specific earbud that works with these? Thanks** A: Mine works with a Sony headphone and a Sony earbud. If you have a headphone with a 3.5 MM Jack I would try that and if it doesn’t work I would think that you’re adapter is defective. ## Customer Reviews ### ⭐⭐⭐⭐⭐ works as promised *by E***A on February 20, 2026* Grade A - works as promised - adds a capability to the Baofeng DM-32UV ### ⭐⭐⭐⭐⭐ Finally the right setup for my shooting protection *by J***Y on March 14, 2021* I have an Import Sport hearing protection which has an audio input.

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. ## Frequently Bought Together - 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 - Baofeng UV-5R Two Way Radio Dual Band 144-148/420-450Mhz Walkie Talkie 1800mAh Li-ion Battery(Black) - BTECH PC03 FTDI Universal Plug & Play USB Programming Cable for BTECH, Baofeng, Kenwood Radios - Compatible with UV-5R, BF-F8HP, GMRS-V2, UV-82HP & More - Easy Setup, No Driver Needed --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/69160536-btech-universal-2-pin-k1-to-3-5mm-audio-adapter](https://www.desertcart.co.uk/products/69160536-btech-universal-2-pin-k1-to-3-5mm-audio-adapter) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-01*
