Our Verdict
TOZO NC9 Truly Wireless
Cowin Apex Elite Truly Wireless
The TOZO NC9 Truly Wireless are better headphones than the Cowin Apex Elite Truly Wireless. The TOZO are better-built, and they offer a more balanced mid-range. Also, their ANC feature isolates against more background noise, and they leak less audio. That said, the Cowin are more comfortable.
