FiiO expands its hi-fi line-up with the JT9 planar headphones leading the charge

FiiO has expanded its hi-fi line-up with three new products, headlined by the JT9 planar magnetic headphones.

The latest products from FiiO lean heavily into high-power desktop audio but keeps portability and modern connectivity in view.

The JT9 is the most immediately consumer-facing of the trio. It uses a large 95 × 86mm planar magnetic driver paired with an ultra-thin diaphragm. This design is claimed to resolution, transient response, and overall tonal accuracy. FiiO also highlights its dual-coating diaphragm technology and a uniform magnetic field structure, which aim to reduce distortion and improve detail retrieval across the frequency range.

Despite the scale of the driver system, the JT9 remains relatively lightweight at 365g for a pair of planar headphones. Unusually for this type of headphones, it includes a foldable design for easier storage. A sensitivity rating of 95 dB/mW allows it to remain usable across a range of sources, and FiiO has included both 3.5mm and balanced 4.4mm cables in the box to cover different setups.

Alongside the JT9, FiiO brings forth its LEVEL 1 desktop amplifier, which sits firmly in the high-power category with up to 2 × 300W output based on the Texas Instruments TPA3255 Class D amplifier. It supports a wide range of inputs that includes RCA line-in, USB, coaxial, and Bluetooth 6.0 with LDAC.

The LEVEL 1 also adds subwoofer and pre-out connections, and includes physical bass and treble controls that give it a slightly retro, hands-on feel. Internally, FiiO has used a six-layer immersion gold PCB and a mix of German and Japanese capacitors. The chassis combines aluminium with wood accents to soften its otherwise industrial design.

Rounding out the announcement is the fully discrete Class A headphone amplifier. It delivers 1000mW + 1000mW output through a custom 60W toroidal transformer and regulated power supply system. It includes five gain levels and a wide set of connectivity options. These include 3.5mm, 4.4mm, XLR, and RCA in/out, alongside 12V trigger support for integration into larger audio systems.

Pricing for all three products is yet known at this moment in time, but will be announced during Vienna High End later this week.
