It couldn't be simpler to set up. Galaxy S22 Ultra connected to it with no problems using LDAC. Sound quality? I mean it's in a car so a $1000 Dac will sound the same as a $5 dac implementation. Comes with a short charging cable which is perfect for my car (Lexus LS460) in-glovebox aux and power connections. Also comes with a longer audio cable in case you want to place the receiver somewhere else. It works perfectly inside the glovebox with the lid closed, no wires, nothing to see or worry about. Hook the power up to a cig lighter usb adapter (if you don't have a usb port in an older car like mine) and dont worry about it ever again. Overall it's the only BT adapter I found that supports LDAC codec so it's worth the $10 extra price premium. Alot of the other adapters being sold boast about their Bluetooth version numbers, like 5.1, 5.3 etc. That refers to the power usage and range. It means absolutely nothing in terms of audio. What matters is what codec it supports. AptX, AptXHD, AptX Adaptive, SBC, or LDAC. SBC is the worst of them all, which, if you're shopping for one of these, is the default lowest tier in terms of audio quality. If they don't state what codec they support, then they support only SBC. Believe me - if their receiver actually supports any of the better codecs, they WILL advertise it. Out of all of them, AptX Adaptive is the highest bitrate and quality, followed by LDAC, then AptXHD and AptX, then finally SBC.
Don't be fooled by some Bluetooth version number - always look for the codec they support.
If you have an iphone, then you're screwed because Apple doesn't support any of these codecs, they use their own proprietary one which none of these units support. So you'll be stuck with SBC.
