Continuing from this wireless earphone thingy, I needed something to connect to it from PC. I initially bought a cheap TP-Link Bluetooth adapter but it ended up sounding crap. Not sure why but it produces so much noise.
So I got the thing above and it sounds quite a bit better. The codec choice doesn’t seem to differ much between SBC and aptX. Although I think the latency is every so slightly better with aptX? It’s still to slow for watching video (fixable by adjusting delay) or playing games (lost cause) though.
The quality difference is almost enough to justify the price difference of over 5 times the cost of that cheap BT adapter. It’s also able to connect to my earphones way more smoothly with no fiddling on Windows side (nothing to fiddle anyway).
The final setup looks rather silly though with my case not having USB-C port and thus requires the USB-C to USB-A adapter resulting in USB flash drive-sized… thing.
