Overview

The FiiO FT13 is a closed-back, wired over-ear headphone built around a 60mm dynamic driver, wrapped in purpleheart wood earcups finished in Black or Mahogany. It sits above the FT1 in FiiO's closed-back lineup, adding swappable lambskin and suede earpads and a magnesium alloy headband with a lambskin contact surface for a more refined fit. Where the FT1 ships with two cables, the FT13 includes three cable options — a 3.5mm, a 4.4mm balanced cable, and an XLR-4 adapter — built from Furukawa monocrystalline copper and silver-plated oxygen-free copper. The standout is that pad-and-cable flexibility together, letting one headphone adapt to different sources and listening preferences rather than locking you into a single setup.

Simcoe Audio Video Insight

The swappable earpads on the FT13 aren't just a comfort feature — lambskin pads tend to seal a little tighter for firmer bass and more isolation, while the suede pair breathes more and can feel a touch more open, so it's worth trying both rather than leaving whichever pair came installed. The included XLR-4 adapter matters most if your amplifier uses a 4-pin XLR balanced output rather than a 4.4mm jack, which is common on some desktop gear — without it, the FT13's cable set would only cover 3.5mm and 4.4mm connections. The Furukawa monocrystalline copper used in the included cables is a step above the plain OFC cable that ships with the FT1, which is part of why the FT13 sits higher in FiiO's closed-back range.

Best for the FiiO FT13: Try both included earpad sets before settling on one, and use the XLR-4 adapter if your desktop amp has a 4-pin balanced output rather than 4.4mm.

More Details

Why It Wins

• Swappable lambskin and suede earpads: both included, letting you adjust fit and tonal balance without buying extra pads.
• Three cable options: a 3.5mm cable, a 4.4mm balanced cable, and an included XLR-4 adapter cover portable and desktop balanced setups alike.
• Purpleheart wood earcups: available in Black or Mahogany, giving the FT13 a distinct look within FiiO's closed-back lineup.

What Makes It Different

Most closed-back headphones ship with a single fixed earpad material and one cable. The FT13 includes both lambskin and suede pads plus an XLR-4 adapter alongside its 3.5mm and 4.4mm cables, giving it more flexibility for desktop and portable setups than a typical single-cable, single-pad headphone in its category.

Technical Highlights

• 7Hz-40kHz frequency response: a wider range than the FT1's 10Hz-40kHz rating, from the same 60mm driver size.
• 32Ω impedance with 98dB/mW and 113dB/Vrms sensitivity at 1kHz: easy enough to drive from a phone or DAP while still responding to a dedicated amp.
• 356g weight with a magnesium alloy headband: a lighter frame than an all-metal design, with a lambskin contact surface for comfort.

Buyers Guide

Who This Is For

• The Pad-Swapper: anyone who wants to fine-tune fit and tonal balance between two included earpad materials rather than being stuck with one.
• The XLR Desktop User: anyone whose amplifier uses a 4-pin XLR balanced output, since the FT13 includes the adapter needed to use it directly.
• The Materials-Focused Buyer: anyone who wants a closed-back headphone with premium touches — purpleheart wood, a magnesium alloy headband, and higher-grade cables — beyond what the entry-level FT1 offers.

Ideal Use Case

• Private desktop listening with a dedicated amp: especially for anyone using the XLR-4 adapter with a balanced desktop source.
• Portable listening: the 3.5mm cable and 32Ω impedance keep it usable straight from a phone or DAP.
• Switching pads by genre or comfort: lambskin for tighter bass and isolation, suede for a more breathable, open feel.

What To Pair It With

• FiiO K9 Pro ESS desktop amp: its XLR-4 balanced output pairs directly with the FT13's included adapter.
• FiiO K11 R2R or K13 R2R: desktop DAC/amp options for a warmer-sounding pairing on the 4.4mm balanced cable.
• FiiO KA17 dongle DAC: a portable balanced option for using the FT13 away from a full desktop setup.

Alternative Options

The FT1 offers a simpler version of the same closed-back dynamic formula, with a single earpad type and two cables instead of three. The FT1 Pro and FT5 move into open-back planar territory for a different, more spacious sound, while listeners who want FiiO's most advanced planar design should look at the flagship FT7.
