Superlux HD-662 B Review: comfort for long sessions

Customer Review Summary

Introduction

The Superlux HD-662 B is a closed-back, over-ear headphone released in 2011, targeting musicians and audiophiles needing affordable monitoring or stage use. Priced at just £29, it promises high external noise reduction and a powerful bass response, all within a lightweight 252g design including cable. This review assesses whether it delivers on sound, comfort, and durability in its price category.

Design and Build Quality

The HD-662 B’s form factor is robust yet utilitarian, featuring a completely plastic construction save for a metal headband core. The design is circumaural, intended to fully enclose the ears, crucial for noise isolation in studio contexts. The headband automatically adjusts its size when worn, accommodating a range of head sizes without manual tweaking. However, some users with larger heads report tightness, with the band maxed out at extension.

Included accessories are a 6.3mm screw-on stereo adapter and a carry bag. The cable is non-detachable, flat, and measures 2.5 metres, terminating in a standard 3.5mm mini-jack. Reports indicate the cable is the most vulnerable element, prone to failure near the plug and difficult to repair due to its thin wiring and moulded connectors. This weakness detracts from overall durability.

Comfort

Comfort has mixed responses. The ear cups sit around the ears but some find the pads stiff and slightly too small for full circumaural coverage, resulting in mild pressure after extended use. The headphones weigh 252 g, which is moderate, but the firm clamping force may cause discomfort during sessions over one hour. Others with smaller or average-sized heads find the fit secure and stable, advantageous for active use on stage or during recording where movement is expected. The fully closed design tends to trap heat, causing ears to feel warm after prolonged listening.

Audio Performance

The HD-662 B offers an impedance of 32 ohms and a frequency response spanning 10 Hz to 30,000 Hz, which covers and exceeds the typical audible range. Peak sound pressure level is rated at 98 dB, suitable for monitoring and casual listening without external amplification, although some users notice improved clarity with a headphone amplifier.

Sound Quality Analysis

• Bass: The headphones present pronounced but controlled bass. It is powerful without muddy bloat or boominess, lending punch to bass lines and drum hits. This resonates well for stage monitoring, especially for drummers and bassists.
• Midrange: The mid frequencies are reportedly slightly recessed or subdued, giving a hint of dip in the mids compared to highs and lows. This may affect the naturalness of vocals or acoustic instrumentation but is common in budget closed-back models aimed at bass emphasis.
• Treble: High frequencies achieve good clarity and separation with a bright tonality. While not harsh or strident, the highs can feel a touch piercing when volume is excessive. Some users describe this as “seedy” but acceptable given the price.
• Soundstage and Imaging: The soundstage is narrow due to the closed design, offering modest spatial cues. Instrument separation is adequate but not expansive.
• Distortion and Volume Handling: Above moderate loudness levels, distortion sets in abruptly, indicating limited tolerance for over-amplification. Caution with gain is advised for listening comfort and headphone longevity.

Comparison to More Expensive Models

In direct comparisons against studio headphones costing 5 to 10 times as much, the HD-662 B surprisingly holds its own in tonal balance and bass response. While it lacks the refinement and extended range of premium sets from brands like AKG or Beyerdynamic, its performance relative to cost is impressive. It is notably better than similarly priced competitors and sufficient for home recording monitoring and casual listening.

Noise Isolation

The closed-back system offers substantial external noise reduction, enough to blunt ambient noise in loud rehearsal or recording environments. Some testers emphasize its ability to block out drums and stage noise effectively, making it suitable for vocal or instrumental tracking without bleed. Leakage of sound is minimal, which is essential when using microphones near headphones to avoid feedback or microphone contamination.

Known Drawbacks

• Comfort Issues: Firm clamping force and stiff pads cause discomfort after long sessions, requiring breaks when used above one hour.
• Cable Fragility: Permanent cable connection prone to failure near the plug, without easy replacement options.
• Fit for Larger Heads: Size limitations for big heads, with maximum band extension causing tightness.
• Soundstage Narrowness: Limited spatial openness due to closed design, less suited for mixing or critical listening demanding wide imaging.
• High-Frequency Harshness: Slightly bright treble can cause listening fatigue at elevated volumes.

Conclusion

The Superlux HD-662 B stands out as a remarkably capable entry-level studio headphone with a sound profile that exceeds expectations for its sub-£30 price point. Its powerful, clean bass coupled with clear highs suits instrumental monitoring and stage use well. The build quality is broadly robust except for the fragile cable, which detracts from long-term reliability. Comfort is acceptable for sessions up to an hour, but harder use or larger heads might find it less suitable.

For musicians, home recording enthusiasts, or anyone needing affordable, closed-back headphones with decent isolation and sound detail, the HD-662 B represents excellent value. While it falls short of professional-grade offerings in refinement and comfort, it remains a favourite for budget-conscious users seeking more than basic consumer headphones.
