Each earbud can play music for up to seven hours on a single full charge. The total playtime increases to about 30 hours with the charging case before a recharge is required.

Q: Are EarFun Free 2S earbuds water- or sweat‑resistant?

Indeed, they have an IPX7 waterproof rating, which makes them impervious to perspiration, precipitation, and unintentional splashes. This makes them appropriate for daily use, running, working out, and rainy commutes.

Q: Can I use just one earbud at a time (mono mode)?

Yes, the left and right earbuds can work separately because of “TrueWirelessTM” technology. Calls, travelling, and situations requiring situational awareness can all benefit from this.

Q: Do these earbuds support touch controls and volume control?

Indeed. With the touch-sensitive controls on EarFun Free 2S, you can answer or reject calls, play or pause music, skip tracks, and turn on your device’s voice assistant. Additionally, you may adjust the volume straight from the earbuds.

Q: What sound quality can I expect? Which audio codecs are supported?

They provide balanced, rich sound with good bass and clarity by using dynamic speakers and supporting audio codecs including aptX, AAC, and SBC.

Q: Is there a low‑latency (gaming/video) mode?

Yes, the Free 2S has a low-latency option (<60 ms) that helps improve synchronisation whether playing games, watching videos, or making video calls.

Q: How clear are calls using these earbuds?

During calls, the earbuds’ four-microphone array with cVc (Clear Voice) noise reduction technology improves voice quality. Under typical circumstances, this helps reduce background noise and enhances call quality.
