Apple's version is first rate and like $15. I use them to connect my computers to Class D Amps, gets me great 5/7.1
For mobile I've had the Qudelix-5K for a couple of years, pricey, but really nice. I forgot and left LDAC 990kbps/96kHz on for months (overkill and bad for battery life), nary a stutter at really impressive ranges. Pretty much makes the audio jack issue irrelevant.
