One is in my daughter's truck and allows her to connect her cell phone to an older radio. The other we use at our church to play music through the sound board remotely. The battery life is good and the sound quality is solid. I ended up using a mono adapter to connect it to the sound board. This seems to work better than a stereo adapter in that application. The ability to connect two devices is a nice feature. Review: Adapter Good for Older Vehicles - This car adapter works well in older vehicles that do not connectors for cellphones.

Cable is provided to plug into the AUX for the car radio and a Type C connector for cellphone. The sound is very good and can use as hand-free device for phone calls. No ambient noise on calls and clear sound for listening to music, podcasts, audio books, etc. Good product. ### ⭐⭐⭐⭐⭐ Good Price, Easy Hack *by G***D on August 24, 2023* I purchased this to replace an FM Bluetooth transmitter in my car (for privacy reasons). Others I searched for didn't have a microphone, making hands free driving while talking an issue, but this does. It worked great, is small, and has not had any issues with connecting/disconnecting. Except one small issue, possibly unique to me. It doesn't power off when it loses power. What that means is after I turn off my car and walkway the connection remains. My music or podcast still playing, and the connection is quite strong. This draining my phone battery faster. To correct this, I opened the case (prying between the sides and the back of the unit). Then removed the battery by disconnecting the small metal leads to, what I assume is, a small power controller. Leaving the controller on the wires to the main board I closed it up. Now the unit only powers on when given power the the USB-C port and turns off when the car turns off. Perfect for what I need at $10 and under 10 minutes of work. ## Frequently Bought Together - UGREEN 5.3 Aux Bluetooth Adapter for Car, [Greater Connection] Bluetooth Aux Adapter for Car, Bluetooth aux for Wireless Audio Receiver for Home Stereo/Wired Speaker, 15H Battery Life - COMSOON Bluetooth Receiver for Car, Noise Cancelling 3.5mm AUX Bluetooth Car Adapter, Wireless Audio Receiver for Home Stereo/Wired Headphones, Hands-Free Call, 16H Battery Life - Black+Silver - HVMLAK Air88 Bluetooth Aux Adapter for Car, Aux Bluetooth 5.3 Receiver with Swivel 3.5mm Audio Jack for Home Stereo Speaker, Volume and Track Control, Handsfree Call, CD Sound, Metal Case --- ## 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.kr/products/592174945-5-4-aux-bluetooth-adapter-noise-cancelling-3-5mm-aux](https://www.desertcart.kr/products/592174945-5-4-aux-bluetooth-adapter-noise-cancelling-3-5mm-aux) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-06-20*
