Connect the 3.5mm PIN BTECH Adapter to your Radio's K1 Accessory Jack 2. Clip or Velcro the PTT Button in a convenient place. 3. Connect your 3.5mm headset to the adapter cable. 4. Turn the radio's volume to the minimum and slowly increase the volume to your preferred level (YOUR EARPIECE WILL NEED VERY LITTLE VOLUME) 5. Earpiece and Headsets that have an Inline Mic built-in can utilize the mic to transmit. In order to transmit use the PTT button on your BTECH Adapter; or the PTT on the Radio directly itself. 6. If you cannot transmit or hear audio - the REVERSE adapter is needed (included). REVERSE ADAPTER INFORMATION The 2 Pin BTECH Adapter to Single Pin Earpiece Adapter includes a Reverse Cable adapter to insure compatibility with all headsets & in line microphone earpieces. The majority of headsets will work without this adapter. Some brands are wired in a reverse fashion and the adapter will be needed on those earpieces. It is recommended to store this adapter a safe place - so you will always be able to adapt your radio to your favorite 3.5MM headphones or line-out options. Package Includes * BTECH 2 Pin to 3.5mm Adapter * Reverse 3.5mm Adapter Review: Just the job - 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. Review: Grade A - works as promised - adds a capability to the Baofeng DM-32UV ## Features - Converts the accessory jack on your Baofeng (or similar) radio to adapt to the standard 3.5mm headsets or audio out jack. - If your headset includes a inline mic - you will be able to use the inline mic for communication. Simply press the PTT button on the radio, or on the supplied PTT on the cable. - The adapter splits into two lines, one line is for your headset to plug into - the second coil includes the PTT button - you can use the supply velcro or snap line to secure the PTT to a convenient location. - Helpful BaoFeng Guides and Programming Tips at Miklor.com - International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B019YJMRZS | | Best Sellers Rank | 1,750 in Headphone & Earphone Adapters 2,385 in Audio & Video Adapters | | Brand Name | B-tech | | Colour | 2 Pin to 3.5MM Adapter | | Compatible Devices | Headphone | | Connector Type | Auxiliary | | Current Rating | 0.12 Amps | | Customer Reviews | 4.3 4.3 out of 5 stars (458) | | Item Dimensions | 106.7 x 5.1 x 0.6 centimetres | | Item Weight | 1 Ounces | | Manufacturer | B-tech | | Model Number | KPG-22 Headset Adapter | | Number of Items | 1 | | Number of Ports | 2 | | Package Quantity | 1 | | Power Plug Type | No Plug | | Product Finish Type | Matte | | Specific Uses For Product | Microphone | | UPC | 722589228803 | | Unit Count | 1.0 count | | Warranty Type | Lifetime | ## Product Details - **Colour:** 2 Pin to 3.5MM Adapter - **Compatible devices:** Headphone - **Connector type:** Auxiliary - **Item dimensions L x W x H:** 106.7 x 5.1 x 0.6 centimetres - **Specific uses for product:** Microphone ## Images ![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 - Image 1](https://m.media-amazon.com/images/I/817mGm69ueL.jpg) ![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 - Image 2](https://m.media-amazon.com/images/I/71CcjZ0vuKL.jpg) ![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 - Image 3](https://m.media-amazon.com/images/I/814HZ5nnMkL.jpg) ![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 - Image 4](https://m.media-amazon.com/images/I/71EWcgAIEHL.jpg) ![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 - Image 5](https://m.media-amazon.com/images/I/81RdiQQaugL.jpg) ## Questions & Answers **Q: does this have a mic built into it?** A: No, it uses the built in mic on your headphones - it includes a PTT button **Q: Which trrs headset standard is this wired for, omtp or ctia?** A: Apple, mic on shield. 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 ### ⭐⭐⭐⭐⭐ Just the job *by P***T on 22 April 2023* 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. ### ⭐⭐⭐⭐⭐ Review *by E***A on 20 February 2026* Grade A - works as promised - adds a capability to the Baofeng DM-32UV ### ⭐⭐⭐⭐⭐ Review *by J***Y on 14 March 2021* 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=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. ## 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.sk/products/117454471-btech-universal-2-pin-k1-to-3-5mm-audio-adapter](https://www.desertcart.sk/products/117454471-btech-universal-2-pin-k1-to-3-5mm-audio-adapter) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-05-18*
