Quick Answer

Choose the Portable DAC Mag Wallet if you want a compact, magnetic phone wallet with a custom USB-C cable for basic on-the-go listening. Choose the Relay DAC/AMP if you need premium sound with balanced outputs, gain modes, and volume control.

What Each Option Does Well

The Portable DAC Mag Wallet is designed for convenience. It combines a phone wallet with a DAC and includes a custom dual-angle USB-C to USB-C cable. The magnetic attachment and elastic holder rings make it easy to keep your DAC and cable together with your phone, so you're less likely to leave them behind.

The Relay DAC/AMP is a more traditional portable DAC/AMP. It packs an AKM SEQ 4493 DAC chip and two ultra-low-noise, high-output drivers into a lightweight, durable body. It offers high/low gain modes, six selectable filter modes, and a 60-step built-in volume control, plus both 3.5mm single-ended and 4.4mm balanced outputs.

These two products serve different listening scenarios. The wallet is about having a DAC always available with minimal fuss. The Relay is about getting the most out of your earphones, especially if you use balanced cables or want to fine-tune the sound.

The Trade-Off: Convenience vs. Performance

The main trade-off is between convenience and performance. The Portable DAC Mag Wallet wins on convenience: it's a wallet, a DAC, and a cable in one magnetic package. But it doesn't offer the advanced controls or balanced output of the Relay.

The Relay DAC/AMP gives you more control over your listening experience. The gain modes and filter modes let you adjust the sound to your earphones and preferences. The 4.4mm balanced output is a key advantage if your earphones come with a balanced cable, as it can deliver more power and lower noise.

Consider how you listen. If you're mostly using your phone with earbuds on a commute and want something that stays attached to your phone, the wallet is a smart pick. If you're a more critical listener who wants to tweak settings and use high-end earphones, the Relay is worth the extra investment.

Cable and Connectivity Differences

The Portable DAC Mag Wallet includes a custom-designed, dual-angle USB-C to C cable that minimizes profile and connection point tension. This is great for keeping the cable low-profile when connected to your phone. It also includes an adhesive magnet ring adapter for devices without magnetic compatibility or with different dimensions.

The Relay DAC/AMP does not come with a cable in the supplied details, so you'll need to provide your own USB-C cable. This is a minor inconvenience but also gives you the freedom to choose a cable length or style that suits your setup.

If you value a ready-to-go solution with the right cable included, the wallet is more straightforward. If you already have a preferred USB-C cable or want to use a specific one, the Relay won't hold you back.

How to Decide: Trade-Offs

  • If you want maximum portability and simplicity: Pick the Portable DAC Mag Wallet. It keeps your DAC, cable, and phone together with a magnetic wallet design, and the included USB-C cable means you don't need to buy anything extra. Check if your phone is magnetic-compatible; if not, use the included adhesive ring adapter.
  • If you want sound customization and balanced output: Pick the Relay DAC/AMP. You get gain modes, filter modes, and a 60-step volume control, plus a 4.4mm balanced output for better performance with balanced earphones. You'll need to supply your own USB-C cable, so factor that into your setup.
  • If you're on a budget: The Portable DAC Mag Wallet is the more affordable option, and it includes the cable, so it's a lower upfront cost. Remember that the wallet doesn't offer balanced output or advanced controls, so consider if you'll miss them.
