iFi Audio Go Link USB-C DAC/AMP Dongle

iFi GO Link

Turn any USB-C device into a serious hi-res listening rig with the iFi GO link. This ultra-compact USB DAC and headphone amp bridges the gap for phones, tablets, and laptops that lack a 3.5mm output—and even when a headphone jack exists, GO link is designed to deliver a clear upgrade in detail, dynamics, and low-noise performance. Inside its lightweight magnesium-alloy housing is an ESS Sabre HiFi-series DAC (ES9219MQ/Q) with iFi’s S-Balanced® circuitry, feeding a gold-plated 3.5mm output to help reduce noise and crosstalk with sensitive earphones and everyday headphones alike. A short, flexible, silver-plated copper twisted-pair cable keeps the connection practical on the go, while hardware-based volume control helps preserve resolution as you adjust loudness from your device. An onboard format LED shows what you’re playing at a glance—so you always know when your audio is running at full quality, including PCM up to 384kHz, DSD256, and MQA rendering.

What It's Good At:

• Upgrading phones, tablets, and laptops with a clean, powerful USB-C DAC + headphone amp
• Driving most headphones and earphones with ample voltage and low output impedance
• Preserving detail with hardware-based volume control (avoids resolution loss from software attenuation)
• Enjoying hi-res playback (PCM up to 384kHz, DSD256, DXD 384kHz) plus MQA rendering
• Reducing noise/crosstalk with iFi’s S-Balanced® headphone output design
• Pocket-friendly durability thanks to a lightweight magnesium-alloy build and flexible cable

iFi GO Link Q&A:

What type of USB input does the iFi GO link use?

The GO link uses a USB-C input. A USB-C to USB-A converter is included in the box for broader compatibility.

What does the GO link’s audio-format LED indicate?

The LED displays both the incoming audio format and (for PCM/DSD) the sample-rate range: Blue = DSD256, Green = PCM 44.1/48/88.2/96kHz, Yellow = PCM 176.4/192/352.8/384kHz, Magenta = MQA renderer, Cyan = DSD64/DSD128.

Does the iFi GO link include a warranty?

Yes. The GO link includes a 12-month limited warranty.

What size headphone plug does the GO link support?

The GO link provides a 3.5mm headphone output.

What devices is the GO link made for?

It’s designed for USB-C devices such as phones, tablets, and computers—especially those without a 3.5mm headphone jack or with weaker built-in audio.

What audio formats can the GO link play?

It supports hi-res PCM up to 384kHz, DXD 384kHz, DSD256 (11.3MHz), and MQA rendering.

Will the GO link work with sensitive IEMs?

Yes. Its low output impedance (<0.4Ω) and S-Balanced® output design are intended to help keep noise low and reduce crosstalk with sensitive earphones.

What’s included in the box?

GO link, a USB-A to USB-C adapter, a Quick Start Guide, and an instruction card.
