EarFun Free 2S Wireless Earbuds

The EarFun Free 2S are true wireless in-ear headphones built for everyday listening and calls. A 7 mm composite dynamic driver delivers powerful bass with detailed mids and treble. Four integrated microphones reduce background noise so voices stay clear. The EarFun app adds multi-EQ adjustment, customisable touch controls and a low-latency game mode.

Commuters and active users who want long playtime

Buyers who need active noise cancellation will not find it here; only passive isolation is provided. Anyone requiring aptX or LDAC codec support should look elsewhere because the specifications list neither. The single-charge runtime of seven hours falls short for listeners who want a full workday without the case.

30-hour total playtime

The earbuds alone run for up to seven hours per charge, and the case extends total listening to 30 hours. A ten-minute top-up adds two hours of playback when time is short. Both wireless charging and USB-C wired charging are supported for flexible replenishment.
