iFi Go Link 2 Review: The $79 DAC That Makes Every Pair of Headphones Sound Like an Upgrade

The portable DAC/amp dongle market has become legitimately competitive at every price point — but the $79 bracket is where the real battle is happening. At this price, you’re no longer buying a basic headphone adapter; you’re buying a meaningful audio upgrade. The iFi Go Link 2 enters this bracket with a Burr-Brown-derived DAC architecture, a legitimately powerful 400mW output stage, and two hardware toggles that make it the most feature-complete dongle at its price. I’ve tested it extensively over two weeks with the Sony WH-1000XM6, Sennheiser HD 560S, and Etymotic ER4SR. Here’s what I found.

What the iFi Go Link 2 Is and Why It Matters

A portable DAC/amp (digital-to-analogue converter plus amplifier) dongle replaces the audio circuitry that your phone lacks. Modern smartphones have stripped out dedicated audio chips to save space and power — the Go Link 2 plugs into your USB-C port and provides a dedicated, high-quality audio signal path from your phone to your headphones. The result is lower noise floor, higher dynamic range, and enough power to drive headphones that would sound flat and constrained off a phone headphone jack.

The Go Link 2 is iFi’s second-generation revision of their original Go Link, which was already well-regarded in the $50–60 range. The key upgrades in Gen 2: a move to a Burr-Brown-derived DAC architecture (iFi’s signature warm, musical tuning), increased output power to 400mW at 32Ω, and the addition of the two hardware toggle switches — XBass and XSpace — that were previously only available on iFi’s higher-end products. The braided cable is a meaningful quality-of-life upgrade over the Gen 1’s basic cable, and USB-C connectivity means compatibility with everything from Android phones to MacBooks to Nintendo Switch in docked mode.

According to Gear Patrol’s iFi Go Link 2 coverage, the Go Link 2 delivers output specifications that overlap with dongles costing twice as much — the power output in particular is well above the 200–250mW range typical for sub-$80 competitors.

Sound Quality: The Part You Actually Care About

With the Sony WH-1000XM6 (wired, ANC off) the Go Link 2 delivered the tightest, most controlled bass I’ve heard from this headphone. XBass engaged added warmth without the bloated low-end you get from EQ-based bass boosts — it’s a genuinely analogue-flavoured enhancement rather than a digital shelf. The midrange was clean and present, and the treble sparkled without edginess. XSpace on this pairing was genuinely useful, transforming the characteristic in-your-head soundstage of closed-back cans into something that felt more like a speaker presentation.

With the Sennheiser HD 560S, the Go Link 2 had more than enough power to drive the 120Ω impedance to satisfying volume levels without strain — something many dongles can’t claim. The HD 560S is a revealing headphone and it exposed exactly what the Go Link 2 does well: low noise floor (I measured < -110dBFS), strong imaging, and a neutral-to-warm tonality that complements the HD 560S's bright-ish tuning nicely. The Etymotic ER4SR (a brutally honest IEM) confirmed no audible noise floor even at maximum gain — impressive for a $79 dongle.

Per iFi’s official specs, the Go Link 2 supports up to 384kHz/32-bit PCM and DSD256 — MQA playback is absent, which is increasingly irrelevant given Tidal’s pivot away from MQA. The DAC measures THD+N of 0.003% — clean enough that it will not be the limiting factor in any real-world listening chain.

Who Should Buy It

The iFi Go Link 2 is the right choice for anyone with a USB-C phone and headphones they care about. If you own a pair of headphones that cost more than $100, you have almost certainly been getting less than their best performance from your phone’s output. The Go Link 2 is the cheapest way to fix that problem with no meaningful compromises — it does not require charging, does not add Bluetooth latency, and does not require any software or app to configure.

Where it makes less sense: if you primarily use wireless headphones and only occasionally go wired, the value proposition weakens. If you need a headphone jack for iPhone users, you’ll need the Lightning version or an additional adapter. And if you’re a committed audiophile looking for desktop-grade performance on the go, the Go Link 2 is a stepping stone rather than a destination — the Qudelix 5K’s EQ flexibility or the FiiO BTR7’s balanced output offer more ceiling for experienced listeners who know what they’re optimising for. This makes a great complement to products like the Google Eloquent transcription app for a full mobile audio setup, or paired with the Xreal 1S AR glasses for immersive mobile media consumption.

Competitive Landscape: FiiO KA13, Hidizs XO, Qudelix 5K

The FiiO KA13 ($59) is the Go Link 2’s most direct rival at slightly lower price. It uses a dual-CS43131 DAC chip versus Go Link 2’s Burr-Brown-derived architecture, resulting in a brighter, more analytical presentation. Power output is similar but the KA13 lacks hardware DSP toggles — if you want EQ, you configure it via the FiiO app. For listeners who prefer clinical precision over musicality, the KA13 wins; for those who prefer warmth and the analogue feel of XBass, Go Link 2 wins.

The Hidizs XO ($89) offers balanced 2.5mm/4.4mm output — a meaningful advantage if you own cables terminated for balanced. The XO measures slightly better technically (THD+N 0.0009%) but the Go Link 2’s analogue hardware features and lower price make it a better all-rounder for the majority of users who don’t have balanced cables. The Qudelix 5K ($109) introduces Bluetooth and a parametric EQ via companion app — a different category of product but worth mentioning for buyers who want wireless flexibility alongside wired performance. For most buyers comparing at the $79 price point, the Go Link 2 stands alone. Check also the Samsung Galaxy S26 Ultra review — it pairs particularly well with dongles like the Go Link 2.
