iFi has unveiled the GO cable, a compact USB-C accessory that combines a DAC, headphone amplifier and IEM connection, offering high-resolution support and inline controls in a sleek, space-saving design.
iFi has pushed its portable audio formula into an even smaller format with the GO cable, a USB-C lead that folds a DAC, headphone amplifier and IEM connection into one piece of hardware. Rather than hanging a separate dongle from a phone or laptop, the cable itself terminates in 0.78mm 2-pin connectors for compatible in-ear monitors, making it a neater option for listeners who want to reduce clutter without giving up wired playback. According to iFi’s announcement, the cable is priced at $79 in the US.
The technical specification is unusually ambitious for such a compact product. iFi says the GO cable supports PCM playback up to 32-bit/384kHz and native DSD256, with the digital-to-analogue conversion handled inside the cable rather than by the source device. The company also claims features borrowed from its GO range, including Dynamic Range Enhancement, S Balanced single-ended output architecture and THD compensation designed to reduce distortion. Those figures are clearly above what most streaming services currently deliver, but they do indicate that the cable has ample decoding headroom for high-resolution files.
The cable also adds practical features that make it more than a simple audio adaptor. Inline buttons cover volume, play/pause and track skipping, while an integrated microphone supports calls and game chat. iFi says the product is compatible with supported gaming devices, including the Nintendo Switch 2 and GameChat, and Android users can access further controls through the Nexis app for firmware updates, volume limiting and selectable digital filters. That app support is limited to Android, which narrows its appeal for some buyers.
iFi is not first to explore this sort of cable-based approach. HIDIZS previously offered a similar concept with the ST2 Pro, pairing a detachable 0.78mm 2-pin cable with an ESS DAC, microphone support and inline controls. What sets iFi apart is the way it combines that format with features drawn from its established GO line and an Android software layer, while staying focused on direct IEM use rather than a broader dongle-DAC role. Reviews of products such as the Go Link, Go Blu and Go Bar have shown that iFi already has a strong reputation in compact portable audio, but those devices still rely on a separate box in the signal chain.
That focus also defines the product’s limits. iFi has not published output power or output impedance figures, so the GO cable should be treated as an IEM-specific accessory rather than a universal portable amplifier. It will suit users who mostly listen from USB-C phones, tablets, laptops or handheld gaming devices and want a lighter setup. It is less convincing for anyone who needs 4.4mm balanced outputs, swaps frequently between IEMs and full-size headphones, or wants a more powerful standalone DAC such as FiiO’s KA15. iFi is also selling a $99 starter kit with its AIRO Astra IEMs, which turns the concept into a more complete beginner package.
