If you want a self-contained, cable-free setup for cycling and everyday training, choose SoundPEATS Air5; if you need to upgrade the sound of the wired earphones you already own from a phone or laptop, choose iFi GO Link 2. These two products sit in completely different categories, and that single fact settles most of the buying decision before you read another word.
• SoundPEATS Air5 biggest strength: A complete wireless package — LDAC and aptX Lossless codecs, adaptive hybrid ANC, IPX5 water resistance and up to 37 hours of total playtime with the charging case.
• SoundPEATS Air5 biggest trade-off: It is fully wireless, so it depends on Bluetooth and its own battery; there is no wired fallback when the cells run down.
• iFi GO Link 2 biggest strength: A portable USB DAC plus a pair of titanium-plated in-ear earphones, pushing up to 32-bit/384kHz PCM and native DSD256 through a precision-milled aluminium body.
• iFi GO Link 2 biggest trade-off: It is a wired chain. You supply the phone, laptop or tablet, and you accept a cable running from your pocket to your ears.
• Pick SoundPEATS Air5 if you want one box that handles music, calls, wind noise and workouts without plugging anything in.
• Pick iFi GO Link 2 if you already own good wired earphones or want a compact desktop-grade DAC for lossless files on the move.
The Air5 is built around convenience that does not sacrifice specification. It carries dual certification for Snapdragon Sound and Hi-Res Audio, and it supports both LDAC at up to 990kbps and aptX Lossless — meaning it can transmit roughly three times the data of standard Bluetooth when your source device supports those codecs. Inside sits a custom 10mm driver with a multi-layer PU+PEEK diaphragm and an N50 dual magnet system, tuned for smooth mids, clear highs and controlled bass. A fully isolated rear chamber adds a physical barrier against noise, and adaptive hybrid ANC does the electronic work on top of it.
Who should buy it? Anyone who wants one pair of earbuds for commuting, training and calls, and who values a genuinely long runtime between charges. Who should skip it? If your phone or player does not support LDAC or aptX Lossless, you will not extract the full codec benefit, and if you insist on a wired signal path for critical listening, this is the wrong shape of product entirely.
iFi GO Link 2: Who It's For
The GO Link 2 is a different animal: a USB DAC and headphone amp bundled with the AIRO Astra earphones. You plug it into a phone, tablet, laptop or PC and it takes over digital-to-analog conversion, running an ESS DAC that supports up to 32-bit/384kHz PCM and native DSD256. The engineering claims are specific — THD compensation that cuts distortion by 62%, dynamic range enhancement adding up to 6dB of extra dynamics, and silver-plated twisted copper conductors for signal transfer. The S-Balanced output halves crosstalk for cleaner playback, and the iFi Nexis mobile app lets you switch between customisable filters.
The physical design leans portable. The aluminium alloy body is 8% smaller than before and 29% lighter, which matters if it lives in a pocket or a bag. The bundled AIRO Astra earphones use titanium-plated dynamic drivers for fast transients and high detail retrieval, with a lightweight ergonomic housing for a secure fit. Noise control is passive — the seal does the work, not electronics. Note the frequency response figure of 80kHz, which points at high-resolution material rather than casual streaming.
Who should buy it? Someone with a wired earphone or headphone collection who wants better sound from a laptop or phone, or a listener with a local library of lossless and DSD files. Who should skip it? Riders and gym users who want nothing tethered to their body. A cable is the whole point here, and no amount of DAC quality changes that.
• Best for cycling and workouts → SoundPEATS Air5. IPX5, an ergonomic in-ear fit, AI wind noise reduction and no cable to snag.
• Best for cable-free convenience → SoundPEATS Air5. Bluetooth 5.4 with LE Audio, touch controls and an app for EQ.
• Best for battery life → SoundPEATS Air5. Up to 37 hours total, 30 from the case, and a 10-minute charge returning 2 hours.
• Best for noise control → SoundPEATS Air5. Adaptive hybrid ANC plus an isolated rear chamber; the GO Link 2 relies on passive isolation only.
• Best for high-resolution wired playback → iFi GO Link 2. 32-bit/384kHz PCM and native DSD256 through an ESS DAC.
• Best for upgrading existing wired earphones → iFi GO Link 2. It slots into whatever you already own and improves the conversion stage.
• Best for a phone or laptop as your main source → iFi GO Link 2. The bundle includes the AIRO Astra earphones, so it works out of the box.
• Best for travel-light listening → iFi GO Link 2. The aluminium body is smaller and 29% lighter, though you still manage a cable.
If you specifically need transparency mode earphones for cycling — letting ambient sound in while you ride — note that the Air5's adaptive ANC is designed to reduce noise rather than pipe it in, so plan your use case around that. If you are shopping for the best foldable kids headphones for cycling, neither of these is that product; both are in-ear designs, and the Air5 is the more practical family choice because it is wireless and sweat-resistant.
For cycling in 2026, I would buy the SoundPEATS Air5. Nothing tethered to my body, IPX5 to shrug off sweat and spray, wind noise reduction built for exactly that environment, and up to 37 hours of playtime mean fewer charging interruptions and fewer things to think about mid-ride. The iFi GO Link 2 is a genuinely interesting piece of kit and, in my opinion, the better pick for a desk or a quiet commute with lossless files. But if the question is which one belongs on a bike, the answer is the wireless one. Check the current price on Amazon before you commit, since the two sit in different budget brackets.
Yes, in my opinion it is the better fit of these two. It is wireless, rated IPX5, uses AI wind noise reduction and offers up to 37 hours of total playtime with the case. There is no cable to catch on anything.
No. It is a wired USB DAC and headphone amp. It connects to a phone, tablet, laptop or PC and passes signal to wired earphones — the AIRO Astra pair is included in the bundle.
The SoundPEATS Air5. It uses adaptive hybrid ANC plus an isolated rear chamber. The iFi GO Link 2 relies on passive noise cancellation, which depends entirely on how well the ear tips seal.
To use LDAC or aptX Lossless, yes — your source device needs to support those codecs. Over a standard Bluetooth connection the earbuds still work, but you will not get the full high-resolution transmission.
