Superlux HD990150 High Impedance Open Back Studio Monitoring Headphones

The Superlux HD990 Open-Back Studio Headphones (150 Ω) are designed for musicians, producers, audio engineers and critical listeners who demand accurate, natural sound reproduction from professional studio equipment. Whether you're mixing a track, mastering a project, editing audio or enjoying high-resolution music through a dedicated headphone amplifier, the HD990 delivers the clarity and detail needed to make confident listening decisions.

The fully open-back design creates a spacious, natural soundstage that accurately reproduces the position of instruments and vocals within a mix. This wide stereo image makes it easier to hear subtle details, judge reverb and panning, and identify tonal changes that can be difficult to detect with closed-back headphones. Large 50 mm neodymium drivers provide excellent transient response with a balanced frequency response across the entire spectrum. Tight, controlled bass, detailed midrange and smooth, natural highs allow you to hear your recordings as they truly are without exaggerated frequencies masking important details.

Comfort is equally important during long studio sessions. The lightweight frame, breathable velour earpads and moderate clamping force provide a secure fit while remaining comfortable for hours of continuous use. The open-back design also helps reduce heat build-up around the ears, making extended listening sessions more enjoyable.

With a 150 Ω impedance, this version is optimised for use with dedicated headphone amplifiers, professional audio interfaces, studio headphone distribution systems and high-quality hi-fi equipment that can provide the voltage required to drive higher impedance headphones effectively. When paired with suitable equipment, the 150 Ω version offers excellent headroom and is well-suited to critical monitoring, mixing and extended listening sessions in professional and enthusiast audio environments.

Built with durability in mind, the HD990 combines a refined, lightweight design with quality materials that make it a reliable choice for professional recording studios, serious home producers, mastering engineers and hi-fi enthusiasts seeking an open-back headphone designed for dedicated audio systems.
