Frequently Asked Questions

A DAC/AMP is a digital-to-analog converter combined with a headphone amplifier. It takes the digital audio signal from your phone, tablet, or computer and converts it into a cleaner, more powerful analog signal for your headphones or IEMs. Compared with built-in outputs, a dedicated DAC/AMP like Relay can deliver more detail, better dynamics, and tighter control, especially with higher-resolution music files and sensitive in-ear monitors.
Relay connects over USB-C and is designed to work with major platforms including Windows, macOS, Android, and iOS/iPadOS (with appropriate adapters where necessary). That means you can pair it with phones, tablets, laptops, and even gaming PCs to upgrade their headphone output and drive your favourite wired earphones or headphones.
Relay uses an AKM 4493SEQ DAC chip and supports high-resolution PCM and DSD playback up to very high sample rates, giving you plenty of headroom for hi-res files. It offers both 3.5mm single-ended and 4.4mm balanced headphone outputs, selectable high and low gain, and multiple digital filter options so you can fine-tune how it responds with different earphones and music.
Built-in outputs are usually designed for convenience, not performance. A dedicated DAC/AMP like Relay can give you a cleaner signal with lower noise, more power, and better control over demanding or revealing IEMs and headphones. If you use high-quality earphones, listen to lossless or hi-res music, or find yourself maxing out your device’s volume, a DAC/AMP is a worthwhile upgrade.
The Portable DAC Mag Wallet is a magnetic phone wallet designed to securely hold a compact DAC like Relay on the back of your phone or compatible case. It includes elastic retention rings, a magnetic attachment system, and a short, dual-angle USB-C to USB-C cable that keeps your setup tidy and reduces strain on the connectors. It’s a practical way to build a clean, pocketable portable rig without loose cables and dangling devices.
Relay is designed to work brilliantly with Campfire Audio IEMs, but it can be used with a wide range of wired earphones and headphones that terminate in 3.5mm or 4.4mm connectors. If you already own other headphones, you can still benefit from its cleaner conversion, additional power, and flexible outputs, then later pair it with Campfire earphones for a complete, matched portable system.
