Fiio FW5 True Wireless Earbuds

The Fiio FW5 is FiiO's flagship true wireless earphone, built by the same tuning team behind the FH9 and aimed squarely at listeners who want wired IEM fidelity without the cable. Each earbud carries a three driver hybrid array and its own dedicated DAC, so the FW5 behaves less like a typical earbud and more like a tiny audiophile IEM that happens to be wireless. Explore more in-ear options in our IEM collection.

Type and Technology

The FW5 is a true wireless stereo earphone with a 10mm DLC diaphragm dynamic driver driven by N50 magnets plus two Knowles balanced armatures per side. An independent AKM AK4332 DAC in each earbud handles conversion, while the Qualcomm QCC5141 platform provides Bluetooth 5.2 with multipoint for two devices and support for LDAC, LHDC up to 900kbps, aptX Adaptive, aptX, AAC and SBC at up to 24 bit 96kHz.

Sound Character

The tuning is natural and mildly V shaped, with articulate balanced armature mids, controlled treble sparkle and punchy low end from the DLC dynamic driver. Soundstage and 3D imaging are the headline act, with reviewers noting the FW5 stages more like a wired IEM than a typical true wireless earbud. FiiO deliberately traded features like ANC for outright fidelity.

Build and Comfort

Each earbud weighs about 6.4g and uses two physical buttons per side instead of touch panels, so controls work reliably in any weather. The shells are IPX4 rated, four microphones with cVc noise cancellation handle calls, and the FiiO Control app adds EQ, codec selection and firmware updates. The 380mAh case charges over USB-C for around 7 hours per charge and 21 hours total.

Best For
