Our Verdict
TOZO T6 Truly Wireless
FIIL T1X True Wireless
The FIIL T1X True Wireless are better truly wireless headphones for sports and fitness than the TOZO T6 Truly Wireless. The FIIL are more comfortable and stable, and their sound profile is better-balanced and more neutral. They also have longer continuous battery life, and they charge in less time. However, the TOZO isolate more noise and leak less sound, and their integrated mic has a better recording quality.
