iFi Audio GO Cable – Hi-Res DAC Amp in a Cable

The GO Cable moves the DAC and headphone amplifier out of the dongle and hides them inside the cable itself. USB-C goes into your phone, tablet, laptop or handheld console at one end, and a pair of 0.78 mm 2-pin plugs clips onto your own in-ear monitors at the other, so nothing extra rides in your pocket.

Key Features

• DAC and amp inside the cable: the hi-res audio system lives in the inline housing, built on the same architecture as the GO link
• ESS Sabre DAC chipset: bit-perfect DSD and DXD decoding, PCM up to 384 kHz and DSD256
• Dynamic Range Enhancement and THD compensation: both unlocked on the DAC chip for wider contrast between quiet and loud passages and lower distortion
• Direct 2-pin connection: 0.78 mm 2-pin L/R male plugs fit standard detachable in-ear monitors
• In-line controls and microphone: volume, play, pause and skip, plus an echo-cancelling mic for calls and voice chat
• Console ready: works with the Nintendo Switch 2, including GameChat
• Silver-plated conductors: OFHC copper with pure silver plating, housed in a water-resistant chassis
• Low output impedance: under 1 Ω, so sensitive multi-driver IEMs keep their intended frequency response

Customer Benefits

A phone headphone output is a compromise, and a separate dongle is one more thing to lose. The GO Cable removes both problems at once: you keep the IEMs you already own, swap the stock cable for this one, and the signal never touches your device analogue stage. At 16 g it adds almost nothing to the weight of the cable it replaces, and the inline buttons mean your phone can stay in your pocket on the tram or in a queue.

Use Cases / Ideal For

Commuters and travellers who already own 2-pin IEMs and want one cable instead of a cable plus a dongle. Handheld gamers on the Switch 2 who need GameChat with a mic that works. Desk listeners who want a clean USB-C path from a laptop to sensitive in-ears without a desktop amp.

Compatibility

Any in-ear monitor with standard 0.78 mm 2-pin sockets, connected to a USB-C source: Android phones, iPhones with USB-C, iPads, Windows and macOS laptops, and the Nintendo Switch 2. The supplied adapter covers USB-A sources. IEMs with MMCX or proprietary connectors are not compatible.

Pros & Cons

✅ Pros:

• Removes the dongle entirely, so there is one less item to carry and lose
• Full ESS Sabre hi-res decoding with DRE and THD compensation at an entry-level price
• Output impedance under 1 Ω suits sensitive multi-driver IEMs
• Inline mic and transport controls make it usable for calls and gaming, not just playback

⚠️ Cons:

• Only fits 0.78 mm 2-pin IEMs, so MMCX owners are out
• 14 mW into 300 Ω means it is built for in-ears, not for full-size high-impedance headphones
• The DAC is tied to this one cable rather than shared across all your headphones

The GO Cable is the smallest way iFi has found to put a real DAC and headphone amp between your source and your in-ears.
