Through the FiiO Control APP, users can also choose their preferred audio codec, allowing them to optimize their connection stability even in challenging environments.

Users can conveniently adjust the volume manually within the app to suit their listening preferences.

The earphones offer a well-balanced sound signature with tight and controlled bass, clean and smooth midrange, and moderately bright treble. These characteristics contribute to a pleasing audio presentation that caters to a wide range of music genres and preferences.

The sub-bass region showcases adequate depth and extension, adding a satisfying low-end punch to the overall sound. The controlled bass ensures that it doesn’t overpower the other frequency ranges, maintaining a balanced and enjoyable listening experience.

Moving on to the midrange, the FiiO FW3 delivers a smooth and full-bodied character, making it ideal for extended listening sessions. The midrange exhibits transparency and airiness, which benefits the clarity of complex musical passages.

In the treble range, the FiiO FW3 continues to shine with a clean, fluid, and smooth presentation. The upper midrange to lower treble transitions are well-controlled, even during moments when instruments are played with higher levels of distortion. The quantity, intensity, and sharpness of this area are well-tuned, resulting in a good grade of separation speed and control, especially when compared to other TWS earphones.

Latency Test

The FiiO FW3 comes equipped with a game mode feature that can be activated through the FiiO Control App. This mode is designed to reduce sound delay, making it more suitable for gaming purposes. While it may not match the performance of specialized gaming earbuds or e-sports earphones, it still offers a satisfactory gaming experience for casual players.

The FiiO FW3 allows users to control the sound delay within 100ms when the game mode is enabled. This reduction in latency enhances the responsiveness of audio cues during gaming sessions, providing a more immersive and enjoyable gameplay experience.

In order to verify the effectiveness of the game mode, multiple tests were conducted using the Latency Test App. With the game mode turned on, the measured latency of the FiiO FW3 was found to be around 102 ms, indicating that it does indeed deliver on the promise of reduced sound delay for gaming purposes. When the game mode is turned off, the latency increases to approximately 137 ms, which is still reasonably acceptable for general use but may be noticeable in more fast-paced gaming scenarios.

Furthermore, the FiiO FW3 performs admirably when used for other multimedia activities, such as watching videos. The earphones maintain flawless sound and picture synchronization on both Android and iPhone devices, providing users with an enjoyable audiovisual experience.


The FiiO FW3 features a charging case with a battery capacity of 380mAh, providing ample power to recharge the earbuds multiple times. Each individual earbud is equipped with a 65mAh battery, contributing to its standalone battery life. The earbuds can deliver up to 7 hours of continuous playback on a single charge, which is decent but not exceptional compared to some other TWS earbuds on the market.

The total battery life of the FiiO FW3, including the charging case’s capacity for recharges, amounts to 21 hours. While this is a respectable duration, it falls within the range of ordinary TWS earbuds in terms of battery performance. Some competing models boast longer total battery life, which may be a consideration for users who prioritize extended usage without frequent recharging.

Unfortunately, the FiiO FW3 does not support wireless charging, which may be considered a drawback for users who prefer the convenience of wireless charging pads or other wireless charging solutions. Instead, users need to rely on the provided USB Type-C charging cable to recharge the charging case.
