Thank goodness we are stepping back in time and manufacturers have found some reason to produce low latency earbuds again.
Four years ago we had aptX-Low Latency providing 30ms delay. Then that got discontinued, and replaced with aptX-Adaptive, which promised worse latency and delivers even worse. I have never measured less than 100ms delay with aptX-Adaptive.
And my Sennheiser aptX-LL earbuds from 2019 now only last 1.5 hours per charge, and I need something to replace them.
I guess this time, instead of 30ms Low Latency, it will be 30ms Ultra-Low Latency.
