There is a new USB Bluetooth transmitter dongle by Avantree hitting the markets at the moment, which I preordered at their 40% early order discount and which I received as one of the first customers at the beginning of August well in time. https://avantree.com/dg60-bluetooth-usb-audio-transmitter The DG60 offers apart from long range, Bluetooth audio and communication capabilities Bluetooth broadcast, too. What interested me were the aptX, aptX LL and aptX HD codecs in the rare combination with headset communication, so listening to BT HD quality and being able to use Skype on PC with a single connection was finally possible. It was originally and until a few days ago advertized with: "Using aptX-HD, wirelessly stream 24 Bit music quality for a ‘better-than-CD’ listening experience." [this is now removed on their site] The DG60 works really well in practice I found - except: On the USB side it is only recognized as fixed 16Bit/48kHz USB audio device in both Windows 10 and Android. No other settings possible! That means everything else has to be up- or downsampled to 16Bit/48kHz. Is that still acceptable as an aptX HD quality level they keep advertising? I wrote Avantree customer support (I also urged them to offer LDAC transmitters) and they opened a ticket. In their reply they confirmed my finding: "Thanks for the feedback, it is extremely helpful. We're currently working on licensing LDAC for our future transmitters. As for the HD quality issue, though the DG60 does support 24 bit, we noticed that all current computers only support 16-bit when using the USB port... we'll be updating our listings so customers don't get confused or feel mislead. Best, Avantree Support"
