Superlux HD 330PRO Over-Ear Semi-Open Headphones 32Ω

The Superlux HD 330PRO are professional semi-open over-ear wired headphones that deliver balanced, immersive sound with 40mm neodymium drivers and comfortable velvet ear cushions for extended listening.

Designed for musicians, podcasters, and music lovers who need accurate audio without heavy amplification, the HD 330PRO combines a semi-open acoustic design with 32 ohm impedance to give you clear highs, warm mids, and solid bass across smartphones, laptops, and studio gear. Its 40mm drivers and carefully tuned enclosure emphasize natural clarity and a sense of space, while the included 6.3mm adapter and soft padding make them ready for both field work and long studio sessions.

How do these headphones sound for everyday music listening?

The HD 330PRO offers a balanced signature: tight, present bass without overpowering the mids, clear vocals, and detailed treble. The semi-open design provides a more natural soundstage than closed cans, so instruments feel more separated and spacious.

• 40mm neodymium drivers for dynamic, distortion-resistant playback
• Stable low end with clear midrange for vocals and acoustic instruments
• Semi-open housing that enhances stereo imaging and room feel

Are these suitable for mobile devices and low-power sources?

Yes — the 32Ω impedance means the HD 330PRO can reach satisfying volumes and preserve detail when plugged into phones, tablets, and laptops without requiring a headphone amplifier. They remain responsive and musical even on portable players.

• Low impedance (32Ω) for use with smartphones and portable DACs
• 3.5mm plug for direct connection and included 6.3mm adapter for mixers
• Consistent performance across common consumer and pro devices

What comfort features make them good for long sessions?

Superlux engineered the HD 330PRO with velvet ear cushions and an adjustable leather-clad headband to reduce pressure and heat during extended wear. The earcups fully enclose the ears to maintain comfort while still allowing some air flow thanks to the semi-open construction.

• Soft velvet pads cushion ears for fatigue-free listening
• Adjustable headband ensures a secure, ergonomic fit
• Semi-open cups minimize clamp pressure and improve ventilation

How flexible are these headphones for studio and live use?

Equipped with a standard 3.5mm jack and a screw-on 6.3mm adapter, the HD 330PRO easily plugs into mixing consoles, audio interfaces, and instrument outputs. Their neutral tonal balance makes them useful for monitoring, reference listening, and on-the-go tracking.

• Included 6.3mm adapter for compatibility with studio gear
• Semi-open design suitable for monitoring with a realistic soundstage
