Review on Techkey USB Bluetooth 4.0 Adapter Dongle: Enhanced Connectivity for PC Laptop Desktop, Stereo Music, Skype Calls, Keyboard, Mouse | Windows 10 8.1 8 7 XP Vista Compatible by James Trapkin

So I installed it on Windows 7 which means you have to download the driver from their website. This is where it starts to get crazy. Download driver? Yes, it is 450MB. Per. A.Bluetooth. Driver. 450MB. Okay, that's it, so I'll continue. I get the driver installation. Everything in the driver is like 2009. These are clearly super, super, super old outdated drivers. But does it seem to work? Phone, headphones and other things seem to pair up. Let's go ahead and play an MP3 track to see how it sounds. Hmm, that's weird, that sounds awful. Almost sounds like 8000 samples per second lol, which nobody has used since 2005. Let's take a look at the advanced driver settings. Well, who would have believed that! This is *IS* 8000 samples per second hard coded in the driver and the maximum possible speed through the dongle. No other sampling rate can be selected. That means any audio you play through it will sound like AM radio from 1978, even if the headphones were amazing. * NO *. Back in the box, come back. INDEED? The fact that this thing only has 8 or 9% of 1 star ratings is a super surprise to me. Perhaps if you have Windows 10, the situation with the drivers will be better. I do not know. But this product is unsuitable for anything related to sound in Windows 7 or other operating systems where you need to get the driver from their website.
