Our Verdict

TOZO T6 Truly Wireless

EarFun Air Pro 2 True Wireless 2021

The EarFun Air Pro 2 True Wireless 2021 are better in-ears than the TOZO T6 Truly Wireless. While both headphones are comfortable and well-built, the EarFun have a more neutral sound profile, which some users may prefer, and their battery performance is better. However, the TOZO have a more stable in-ear fit and can isolate you from more ambient noise.
