CSR Harmony is the only stack that will support aptX.Jim **Q: Will this work with Windows 10?** A: It may be the answer too late. it works fine with windows 10 with its native driver but I don't know CSR Apt-X is working or not. After updated to Win 10 Apt-x pop-up is disappeared and there is no confirmation this is connected with Apt-X or not. Anyway it is working fine for 4 years with my PC. **Q: Does this dongle also supports hid profile? (for mice & kb) it's not advertised @ their web page.** A: Yes. These are listed in my Windows 10 "My Bluetooth Services" list (at the very top of the list). **Q: Is this backwards compatible with older bluetooth versions 2.0, 2.1 and 3.0? Also can you pair a keyboard and a headset at the same time?** A: Yes, it's compatible with all older bluetooth. Yes, you can pair keyboard, mouse and headset at the same time, no problem here. --- ## 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.pl/products/2294808-azio-usb-micro-bluetooth-adapter-v4-0-edr-and-aptx](https://www.desertcart.pl/products/2294808-azio-usb-micro-bluetooth-adapter-v4-0-edr-and-aptx) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-24*
