Our Verdict
EarFun Free Truly Wireless
FIIL T1X True Wireless
The FIIL T1X True Wireless are better for commuting and traveling than the EarFun Free Truly Wireless. The FIIL are more comfortable, have better touch-sensitive controls, and have a more neutral sound profile. They also feel better built, they're able to isolate more noise, and their continuous battery life lasts longer too. They even have an app that offers 15 different EQ presets. However, the EarFun's integrated mic captures voices better and they leak less sound.
