This combo supports the Faststream codec, which allows high quality audio while using the Mic. All the newer ones use Bluetooth LE, so faststream support is basically non-existent now. I was glad to find this older model adapter that still had it. It works perfectly and I'll be able to keep using my old headphones now. This also come with the latest/best firmware which has fixed crackling audio problems I had with previous versions. It's the best version of the this older generation adapter. Review: If I could give 6 stars I would. - I honestly thought that this just wouldn’t work. Or if it did, it would be unreliable, cutting out all the time or having latency issues. I AM SO GLAD THIS PROVED ME COMPLETELY WRONG!! I plugged this product right in, and my Sony XM4s synced right up. It has been a breeze ever since then. It has never failed. It has never gotten staticky. It has never lagged or had latency. Never disconnected randomly or stopped working where I had to unplug and plug back in. No worries about buying this one. I expected that not every single headphone would work with the mic. So in my case, I have to use the mic on the controller, but I don’t use the mic very often anyway. The main part is gaming through the headphones. So as long as you have the expectation that maybe your mic might not work, I don’t believe any of the bad reviews. This thing is incredible. Buy with confidence! ## Features - [Hassle-Free Set Up]: Get wireless Bluetooth audio streaming in no time with the C81.

This is the answer. Just pair each Echo separately, and then hit the music. I was able to move this from a Pixel to a Galaxy without any changes, it honestly "just works." So great to have something like this work as well as this did. Bluetooth is always a pain, but this is amazing. ## Frequently Bought Together - Avantree C81 USB-C Bluetooth Adapter for PS5 - Connect Headphones Wirelessly with aptX Low Latency Support and Included Mini Mic - Beats Studio Pro - Wireless Bluetooth Noise Cancelling Headphones - Personalized Spatial Audio, USB-C Lossless Audio, Apple & Android Compatibility, Up to 40 Hours Battery Life - Black - Beats Solo 4 - Wireless Bluetooth On-Ear Headphones, Apple & Android Compatible, Up to 50 Hours of Battery Life - Matte Black --- ## 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.at/products/417410236-avantree-c81](https://www.desertcart.at/products/417410236-avantree-c81) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-08-30*
