Superlux HD681 AIR Monitoring Headphones 50mm

Superlux HD681 AIR are semi-open, over-ear monitoring headphones with AIR-Cushion earpads designed to deliver detailed, high-resolution sound and extended comfort for studio and casual listening.

The Superlux HD681 AIR edition blends a semi-open acoustic design with large 50 mm neodymium drivers and two earpad options so you can tailor comfort and tonal balance. Built for extended studio sessions, mixing, DJ rehearsal, gaming, and everyday listening, these wired headphones pair a lightweight build and a long single-sided cable with professional-level sensitivity and frequency response.

How do the AIR-Cushion earpads change the sound and feel?

The AIR-Cushion earpads add a subtle vibration layer that creates a perceived increase in depth while controlling bass leakage compared with traditional pads. They produce a slightly more expansive, airy presentation; the included leatherette pads offer a tighter, classic closed-back tonal character.

• Two pad options: air-cushion and leatherette for sound preference switching
• Air-cushions enhance perceived soundstage and reduce bass bleed
• Leatherette pads provide a neutral, familiar studio timbre

What performance can I expect from the drivers and technical specs?

Large Ø50 mm neodymium drivers reproduce a wide 10–30,000 Hz frequency range with 98 dB SPL sensitivity and 32 Ω impedance for clear, high-resolution playback. These specs suit detailed monitoring, accurate mixes, and immersive casual listening across genres.

• 50 mm neodymium drivers for extended dynamics and clarity
• 10–30,000 Hz frequency range for both deep lows and crisp highs
• 98 dB sensitivity and 32 Ω impedance for loud, controlled output

Are they comfortable for long sessions and travelling between projects?

The HD681 AIR was designed for long wear: lightweight construction, soft circumaural earpads, and a headband that reduces pressure make them gentle on ears and glasses. The 2.5 m single-sided cable and included 3.5→6.3 mm adapter give connection flexibility for studio desks, interfaces, DJ mixers, and consumer devices.

• Soft, breathable pads reduce heat and pressure during extended use
• 2.5 m single-sided cable reaches studio equipment without tangling
• Gold-plated plug and 6.3 mm adapter ensure reliable connectivity

How do these headphones fit into a professional or home setup?

The semi-open architecture offers a wider soundstage than closed-back cans, making them a useful choice for mixing references and critical listening at home or in treated rooms. They are versatile enough for casual monitoring, DJ practice, and gaming when you want accurate spatial cues without full isolation.

• Semi-open design balances natural soundstage with studio utility
• Suitable for mixing, tracking references, and attentive listening
• Durable build and adapter included for cross-device compatibility

Who is this for: The Superlux HD681 AIR is aimed at musicians, producers, podcast hosts, gamers, and audiophiles who want a cost-effective monitoring headphone with professional-minded specs and convertible earpads for personalized comfort and tonal choices. If you need extended wearing comfort, accessible connectivity, and an accurate semi-open presentation without investing in high-end studio cans, these headphones make a practical, flexible option.
