FAQs
Q: What devices can I use EarFun TW306 earbuds with?
They are compatible with all Bluetooth-capable devices, including computers, tablets, smartphones, and other Bluetooth audio sources. Simply turn on Bluetooth, look up “EarFun Air Pro SV,” which is the model’s pairing name, and establish a connection.
Q: Do the earbuds have active noise cancellation (ANC)?
Indeed. To provide a more engaging listening experience, the TW306 has hybrid ANC, which reduces background noise (such as traffic and talk).
Q: Can I use just one earbud by itself (mono mode)?
Yes, you may use each earbud on its own. This is helpful when making calls or when you want to keep an eye on your surroundings.
Q: What is the expected battery life?
You can play for several hours on a single charge (depending on ANC on/off, volume, and usage). You can receive several recharges for prolonged use with the charging case.
Q: Do the earbuds support low-latency mode for video or gaming?
Yes, there is a “Game Mode” option that lowers latency to about 80 ms, which is useful for gaming or watching films.
Q: Are they water or sweat-resistant? Are they suitable for workouts?
Indeed, the TW306 can withstand exercise, light rain, and perspiration without any problems because of its IPX5 classification (sweat and light water resistance).
Q: How do I control music playback, volume, and calls?
Touch controls are supported by the earbuds. Depending on the settings, you can answer or end conversations, play or pause music, skip tracks, change the level (for example, tapping the left earbud lowers it while tapping the right boosts it), and more.
Q: What’s the Bluetooth range of the TW306 earbuds?
You can anticipate a working range of up to ~15 meters (≈ 49 feet) under perfect circumstances (clear line-of-sight, no impediments). Depending on interference and obstacles, the real-world range can change.
