60-day audition
Balanced output isn’t just a technical upgrade; it completely transforms the way you experience music. By giving the left and right channels their own dedicated signal paths, balanced audio virtually eliminates noise and interference. That means a cleaner, quieter background where every note and subtle detail stands out with stunning clarity.
For serious headphones, the HXL’s 4.4mm balanced output delivers the extra power and control needed to drive high-impedance or studio-grade models with ease. The result is deeper, tighter bass, incredible dynamics, and a wider, more precise soundstage that makes it feel like you’re sitting in the room with the artist. Once you hear your favorite songs through balanced audio, you won’t want to go back.
Wired headphones aren’t just a throwback, they’re a choice for better sound, greater control, and less digital fatigue. With no compression or signal lag, they deliver clean, full-resolution audio that’s more detailed and easier on your ears at lower volumes. It’s why more DJs, creators, and everyday listeners are making the switch back.
The HXL takes that one step further with true balanced output. Dual DACs and a 4.4mm jack give each channel its own path, cutting noise and crosstalk for pinpoint imaging and a wider soundstage. Whether you’re editing, producing, or just riding the train, it brings your music into focus and makes every track hit harder, sound clearer, and feel more alive.
The Audioengine HXL may fit in the palm of your hand, but it delivers the kind of sound you’d expect from high-end desktop equipment. Housed in an anodized aluminum case, it’s built to last while staying portable. Built-in headphone jacks flatten and dull your music, but the HXL brings every track to life with incredible clarity, depth, and detail. Whether you’re pushing powerful studio headphones or streaming your favorite playlists at home, it unlocks layers of sound you’ve been missing, making every listen feel brand new. Once you hear it, you’ll never settle for ordinary audio again.
The Audioengine HXL packs massive performance into a size small enough to slip into your laptop bag. Powered directly by your device through USB-C, it’s always ready to deliver incredible sound without the hassle of charging. Inside, dual DACs, balanced output, and a precision 60-step digital volume control work together to unlock the full potential of your headphones. Whether you’re driving demanding studio cans or simply upgrading your daily listening, the HXL makes every track sound richer, clearer, and more alive. Just plug in and press play, no apps, no drivers, no barriers between you and the music you love.
The Audioengine HXL keeps things simple so you can focus on the music. Powered directly through a single USB-C connection, it’s always ready to go, no batteries to charge, no extra cords to deal with. Just plug it in and get pure, powerful sound wherever you are, whether you’re at home, on the go, or in the studio.
The HXL includes a headphone amplifier based on the LME49726 delivers 32-bit precision, high dynamic range and ultra low distortion. This headphone amp is able to provide low-impedance, high-fidelity audio to a wide range of wired headphones.
