Auribus Acoustics Sierra

The Auribus Acoustics Sierra is an open-back dynamic headphone designed from the ground up in Southern California, built around a 50mm paper cone dynamic driver, a Patent-Pending Linear Extension system for subwoofer-like bass impact, and a construction philosophy that prioritizes genuine stage realism alongside all-day wearing comfort. Hand-built in Southern California.

Type and Technology

Open-back dynamic headphone. 50mm paper cone dynamic driver. Auribus Patent-Pending Linear Extension system for improved low-frequency extension and impact. Nylon, aluminum, and PETG construction. 20-ohm impedance at 1kHz, a low-impedance design that pairs well with a wide range of amplifiers and sources. Detachable cable with dual 3.5mm connectors. Includes Dekoni Elite Hybrid leather/velour ear pads.

Sound Character

Wide, spacious, and impactful, the Sierra was tuned for a true-to-life soundstage with the physical bass presence and slam that the Linear Extension system enables, contrasted against the detailed and airy presentation typical of the best open-back dynamic designs. A headphone for listeners who want both scale and detail without compromise.

Build and Comfort

Lightweight at 330g without cable. Mixed materials construction combining nylon, aluminum, and PETG for a balance of rigidity and comfort. Padded carry case included for storage and transport. Hand-built in Southern California.

Best For

Audiophiles who want open-back dynamic performance with genuine bass impact and an emphasis on soundstage realism, particularly those who find conventional open-backs too lean in the low end.
