Low latency mode	The product page footnote lists the Xiaomi 14 Ultra, Xiaomi 14, Xiaomi 13, Xiaomi 13 Pro, Xiaomi 13 Ultra and POCO F6 as models that support low latency and says more models are being adapted. The support FAQ says it turns on by holding the touch area of both earbuds for 1.5 seconds outside calls, or in the Xiaomi Earbuds app.
Google Fast Pair	Android devices with Google Play services 11.7 or later, which covers Android 6.0 and later. Fast Pair switches off for 5 minutes after three cancelled attempts.
Xiaomi Earbuds app	Android 6.0 or later (app version 1.20.0i or later) or iOS 14.0 or later (app version 1.11.0 or later). Touch control settings are only available in the app.
