Setup guide

Dual Headphone Outputs

The HXL includes both 3.5mm and 4.4mm balanced outputs, giving you flexibility for everything from sensitive in-ear monitors to demanding studio headphones. Balanced output delivers more headroom, tighter bass, and a quieter noise floor for a true hi-fi listening experience.

Pocket-Sized Power

The compact design of the HXL makes it easy to take anywhere while delivering serious performance. Built from precision-machined aluminum, it’s rugged enough for travel and clean enough for your desktop, proving that portable gear doesn’t have to compromise on quality.

No Batteries, No Charging

Forget about managing extra power cords or waiting for a charge. The HXL draws power directly from your phone, tablet, or computer through a single USB-C connection, keeping your setup clean and ready to play at a moment’s notice.

Upgrade Any Audio Source

Bypassing the built-in sound card of your computer or mobile device, the HXL acts as a high-quality DAC and headphone amplifier in one. Use it to power headphones or connect directly to powered speakers or a Home Music System for a clear, detailed upgrade to any setup.
