The new FW3 True Wireless Earbuds build upon the success of an award-winning range of portable audio equipment from FiiO. ​

Featuring a high-performance AK4332 DAC and Qualcomm’s latest QCC5141 Bluetooth chipset, the FW3 deliver Bluetooth version 5.2 connectivity with a wide range of codec supported, including: LDAC, LHDC, AptX Adaptive, AptX, AAC and SBC. FiiO has also equipped the FW3 with a 10-band PEQ function allowing the users to tune the output more to their liking. By default, FiiO has tuned the FW3 for pure high-resolution audio clarity. The built-in AK4332 DAC and AMP chipset ensure clear signal decoding and pure high-resolution experience.

Over the years, FiiO has gained expertise in designing high-quality In-Ear Monitor Headphones and Digital Audio Players. Featuring a 10mm carbon-based dynamic driver unit, the FiiO audio engineering team have designed the FW3 for a pure high-resolution audio experience; delivering an impressive musicality with excellent bass response, clear midrange, and a detailed treble response.

The FiiO FW3 True Wireless Earbuds are Snapdragon Sound certified. Whether listening to music, gaming, or making voice and video calls, Qualcomm's Snapdragon Sound guarantees an excellent level of HD audio quality, together with low-latency. Enabled by accessing the settings within the companion FiiO Music app for iOS and Android, the FW3 supports Low-latency Gaming Mode which significantly lowers the transmission latency to less than 100ms.

In addition to the Low-latency Gaming Mode, the FiiO Music app gives access to the following advanced settings for the FW3:

  • 10-band Parametric EQ settings. Allows for easy, precise EQ adjustments dependent upon individual listening taste.
  • Manual Bluetooth Codec Selection. Allows you to choose the codec you wish the FW3 to utilise as the default.
  • Left/Right Channel Balance Adjustment.
  • Lowpass Filter Mode Selection. Incorporating the audio expertise found on their range of DAPs, such as the M15S, the FW3 allows the user to personalise their listening by choosing from one of four Lowpass Filter modes: Steep Drop, Slow Drop, Short Delay Steep Drop, Short Delay Slow Drop.

The FW3 feature four physical buttons — two on each earbud — which allow for easy, tactile control. As well as being able to Play/Pause/Select Next Track/Select Previous Track, users can adjust the volume up and down, Answer/End/Reject an incoming call, and activate their mobile device voice assistant.

The FiiO FW3 deliver a battery life of up to 21 hours. The earbuds offer a total of 7 hours from a full charge, with an additional 14 hours from the supplied charging case.
