Review on 🔌 ASUS USB-BT400 USB Bluetooth Dongle Receiver - Compatible with Laptops and PCs, Plug and Play for Windows 10/8/7/XP. Supports Printers, Phones, Headsets, Speakers, Keyboards, and Controllers in Black. by Micha Niemczyk ᠌

I bought to connect headphones via xiaomi mi bluetooth Audio Receiver to a computer. With the phone, this receiver connects in a couple of seconds without any problems and the sound quality does not drop significantly. With a PC (win 8.1), it connects through this adapter for about half an hour and the connection often breaks, after which you have to connect again, while the sound quality drops sooooo much (approximately to the level of headphones from the fixed price). Installing a more recent version of the driver did not help . And why the driver weighs more than 500 MB is somehow not very clear. The adapter itself also turns off once an hour and a half. Its communication radius is about a meter in a straight line without obstacles. As the distance increases, or if, for example, the adapter is plugged into the rear panel, the connection deteriorates very much and periodically breaks. I do not recommend buying, because. The adapter is definitely not worth the money.
