The FiiO JA11 is a compact USB-C to 3.5 mm headphone DAC and amp adapter. It decodes PCM up to 32-bit/384 kHz and DSD128, delivers 30 mW per channel into 32 ohms with a 0.5 ohm output impedance, supports CTIA and OMTP inline microphones and controls, and includes a DSP with a parametric equalizer configurable through the FiiO Control app.

USB-C DAC with DSD128 and Headphone Output

The JA11 uses a compact DAC to convert audio from a USB-C port (Android phone, computer, tablet) to a 3.5 mm headphone jack. It decodes PCM up to 32-bit/384 kHz and DSD128, with a stated output of 30 mW per channel into 32 ohms and a 0.5 ohm output impedance — well suited to most in-ear monitors and portable headphones. 

 

Parametric EQ DSP and Build

An on-board DSP supports a parametric equalizer whose curves are set through the FiiO Control app on Android. Profiles are saved inside the JA11's DSP and remain active when the adapter is later plugged into an iPhone or computer, even without the app. The housing is anodized aluminum-magnesium alloy (95 × 9 × 12.7 mm, 5 g). The captive cable uses palladium-plated oxygen-free copper conductors with a silicone and braided-yarn sheath.

 

Why choose this product?

The JA11 adds a quality 3.5 mm headphone output to a phone, tablet, or computer with a USB-C port, with PCM 32-bit/384 kHz and DSD128 decoding, and a parametric equalizer that can be shaped through the FiiO Control app. It also supports CTIA and OMTP inline microphones and controls.
