You have to be careful with the drivers though.. it does set up as plug and play with windows, however, the sound quality I got from it was terrible. Not sure why.Make sure you install the driver thats provided in the box (or find them online if you have no cd drive) before you plug the dongle in for the first time or you might encounter device connection problems. After setting it up properly, the sound quality and distance are pretty good.It does have a flashing blue light which was kinda annoying, so had to use the black marker to cover it up. ### ⭐⭐⭐⭐ Worked fine on Win10 PC. No problems. *by M***H on Reviewed in the United Kingdom on 8 August 2017* Bought two of these adaptors for my son to to use his Phillips bluetooth headset with his PCs, as well as his iPhone. One on a quite new HP laptop, One on a very old Dell (optiplex) desktop. Both PCs run 64bit Win 10. USB adaptors were recognised by both PCs, Win10 installed drivers automatically, no problems. Worked fine with the headphones. ### ⭐⭐⭐⭐⭐ But overall I m satisfied with this product *by V***T on Reviewed in the United Kingdom on 11 October 2017* This bluetooth device works perfectly for 3 devices where you can get mouse, headphone and mobile phone all connected in the same time. The only downside is the mouse. It takes time to reactive after laptop went sleep or hibernate. Not sure is the bluetooth device design failure or the mouse. But overall I m satisfied with this product. My advise to others is please read the installation manual stored inside the software. People who have the habit of ignoring installation manual will take longer time to figure out how it works. --- ## 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/48314333-lmtech-bluetooth-csr-4-0-usb-dongle-adapter-bluetooth-transmitter](https://www.desertcart.pl/products/48314333-lmtech-bluetooth-csr-4-0-usb-dongle-adapter-bluetooth-transmitter) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-19*
