I purchased this little unit before receiving a set of Plantronics BackBeat PRO 2 Special Edition wireless headphones which I ended up snapping. It sat in my desk drawer waiting for the headphones to arrive while I set up my computer with multiple audio output options and Bluetooth adapters to test the headphones when they were here (motherboard onboard audio, USB sound card, PCIe audio) . card and several types of Bluetooth transmitters with analog input). D-Day came and I loaded up the headphones and used a 26.5 minute FLAC file with a selection of music to test direct connections to all the different audio hardware outputs I had. configured on my computer. Good sound - damn good - especially at the lower end of the audio spectrum. Headphones are a faithful guardian. All of the sound processors I've set up on this computer produced very good sound, and the stack score drops as the PCIe card tops the field and the USB sound card is close to the motherboard's onboard audio. with a nod to the USB sound card which is 5 years newer than the sound hardware on the motherboard. After establishing a baseline, I start testing different ways to route audio through some Bluetooth audio transmitters. I unplugged my motherboard. Loaded the sound hardware in the BIOS settings and the operating system (Debian Linux 9.4), then connected the BT-600 to the rear USB 3.0 port. After logging in, I found that the BT-600 was identified by the operating system as "Plantronics BT600 Analog Stereo". 'LSUSB -v' provides more information than most people need, but I saw what I wanted to see in bus 010 Device 005: ID 047f:02f7: Debian was more than familiar with this device and knows what to do with it is. Suffice it to say that it's defined as a USB connected sound card and the Bluetooth interface is completely outside of the OS - your Bluetooth receivers are the only thing you need to worry about to hear what's coming from the sound card. I skipped testing the motherboard audio hardware as well as the USB sound card and am stuck with a PCIe sound card routed through various Bluetooth transmitters that I lined up for comparison. This made things easier for me as all I had to do was pair the headphones to a transmitter and then to the BT-600 and switch between them on the main channel selector panel. I tested all 8 devices (7 bluetooth transmitters plus BT-600) and was surprised to find that the BT-600 talking to Plantronics headphones was almost on par with a direct connection between the PCIe sound card and the headphones and all the sound threw transmitters out of the water Bluetooth with which I tested it. The .flac file I used to test/compare is a very comprehensive composition with melodic Sanskrit chanting. Poor audio hardware performance usually means that the nuances of speech are lost. In such cases, it is easy to make mistakes in the accurate pronunciation of the words in the performance. With this device, I was pleasantly surprised to find that all aspects of the words being sung are perfectly reproduced, leaving no errors as to the content of the performance. To be honest I'm VERY impressed with this little thing and I'll get more information from other computers I use on a daily basis. Now the BT-600 doesn't come with the headphones I bought (Plantronics BackBeat PRO 2 Special Edition) but works exactly as it's supposed to, offering red, blue and purple lights. , depending on the operating mode at any time.
