iFi Audio recently released a highly innovative product—the GO Cable, which integrates a high-performance DAC and headphone amplifier directly into a USB-C cable, designed specifically for 2-pin IEMs. Priced at just $79 (approximately ¥570), this cable aims to eliminate the traditional "dongle" DAC/amp, allowing users to enjoy high-quality audio without carrying any additional standalone device.

Traditionally, improving sound quality for phones or laptops requires an external USB DAC/amp (commonly called a "dongle"), which, though compact, risks being lost and occupies a port. The iFi GO Cable completely changes this paradigm—it embeds the ESS DAC chip and amplifier circuitry directly inside the USB-C cable, physically removing the burden of an extra attachment. [1]
The GO Cable's architecture originates from iFi's award-winning Go link series of standalone DAC/amps [2]. It bypasses the phone or computer's built-in audio circuitry, directly receiving signals from the digital source and converting/amplifying them with the built-in ESS DAC, unlocking more detail, clarity, and dynamic range. The system is plug-and-play, driverless, and compatible with mainstream platforms like Windows, macOS, iOS, and Android. [2]
Regarding specifications, iFi has not disclosed the exact DAC chip model, but emphasizes that the ESS architecture maintains the brand's signature tuning. The cable uses high-quality shielding and oxygen-free copper conductors, with one end being USB-C and the other a standard 0.78mm 2-pin connector, compatible with most IEMs with detachable cables. Priced at $79, it is available immediately on iFi's official website and authorized dealers. [1]
The biggest highlight of this product is its "invisibility" and "minimalism." Users only need one cable to complete the entire audio chain from phone to earphones, simply bring the phone and the IEMs connected via GO Cable when going out, perfectly solving the trade-off between "poor sound quality when listening on phone" and "the hassle of carrying a dongle." Compared to similar dongle products, the GO Cable has no extra dangling box, making it more pocket-friendly. [1]
Additionally, since the DAC/amp is directly on the cable end, it is inherently closer to the earphone driver than traditional standalone dongles, theoretically reducing cable inductance and noise interference. However, this also means the cable is non-replaceable; if the cable is damaged, the entire module becomes unusable. iFi states that the cable is reinforced for durability comparable to standard upgrade cables. [2]
Editor's perspective: The iFi GO Cable is an extremely precisely targeted product. It is best suited for three types of people: first, mobile music users who pursue ultimate portability and don't want to carry extra items; second, entry-level audiophiles who want to experience balanced output and better decoding but lack the budget for a standalone player; third, IEM users who frequently switch devices (e.g., from iPhone to Android or PC). [1]
Compared to similarly priced (70–100 USD) standalone dongles like Fiio KA1 or Jay's Audio, the GO Cable may not necessarily win in sound quality (after all, standalone DACs often have more circuit space), but its integration offers unmatched convenience. The trade-off is: are you willing to sacrifice a bit of potential sound quality ceiling for a "zero-add-on" experience? If yes, the GO Cable is currently the only choice on the market. [1]
