Customer Review Summary
Introduction
The Superlux HD-660 Pro 32 Ohms headphones offer a compelling package for users seeking a budget-friendly closed-back solution. Released in March 2021, these over-ear headphones feature a 40 mm dynamic driver with neodymium magnets, a 10 Hz to 30,000 Hz frequency response and an impedance of 32 ohms. Priced at approximately £32, they target those who require solid audio performance without hefty investment.
Design and Build Quality
The HD-660 Pro adopts a circumaural, closed-back design aimed at noise isolation and sound leakage control. The overall weight is 323 grams, which, combined with velour ear pads, provides reasonable comfort for extended use. Notably, Superlux has moved from artificial leather towards velour pads, improving breathability and reducing ear fatigue during prolonged listening sessions.
However, the build shows clear cost-saving measures. The metal yoke and plastic components present sharp edges that may require user modification to avoid discomfort. The headband adjustment is stiff and may loosen over time. There are no replaceable cables, the fixed 2-metre cable feels somewhat thin and fragile, exposing the headphones to potential wear issues, especially in active environments. The inclusion of a 6.3 mm adapter thread-mounted onto the 3.5 mm mini-jack is practical but can be cumbersome with some device cases.
Sound Performance
Sound-wise, the HD-660 Pro delivers a balanced and relatively flat tonal signature. The bass response is present but well-controlled, avoiding the exaggerated low-end often found in budget models. While bass precision is generally good, some users report slight blurring below 80 Hz. Midrange clarity is solid, supporting detailed vocals and acoustic instruments without overshadowing other frequencies.
The treble range is extended, reaching up to 30 kHz, but can sound somewhat forward and a little artificial, leading to listening fatigue after long sessions. The soundstage is moderate, typical of closed-back designs, with adequate instrument separation for casual mixing and monitoring tasks.
These headphones are particularly suitable for recording monitoring, as their isolation helps contain bleed and their 32-ohm impedance lets users drive them directly from portable devices or basic audio interfaces without requiring amplification.
Comfort and Practical Use
The HD-660 Pro is comfortable for hours on end thanks to its generous velour pads and moderate clamping force. The headset is relatively lightweight despite its size, but large ears can experience pressure, as the earcups do press somewhat against the head. Ventilation and breathability remain decent, although in warmer conditions some warmth is noticeable around the ears.
Users report that the ear cups’ fit may require manual adjustment to ensure a consistent seal and optimal sound isolation, as the headphone adjustment has limited lateral movement.
Value and Suitability
Given its £32 price point, the Superlux HD-660 Pro offers a remarkable level of performance and comfort. It competes effectively with more expensive closed-back models and presents a viable alternative for gamers, casual listeners, and entry-level studio practitioners.
Its pros include:
- Balanced, flat sound suitable for monitoring and mixing
- Comfortable velour ear pads for extended use
- Low impedance allowing use without dedicated amplifiers
- Inclusion of 6.3 mm adapter and carrying pouch
The cons are:
- Fragile cable with no replacement option
- Build quality shows cost-cutting, including sharp edges
- Isolation is functional but not exceptional
- Sibilance and forward highs may fatigue sensitive listeners
Conclusion
The Superlux HD-660 Pro 32 Ohms headphones stand out in their price range by delivering accurate, relatively neutral sound in a closed-back form factor with good comfort. Minor shortcomings in build quality and cable durability are offset by the overall audio performance, which caters well to home studio environments, streaming, gaming, and everyday music listening.
For those seeking transparent audio reproduction on a tight budget, especially where noise isolation matters, the HD-660 Pro is a strong candidate. Its sound neutrality supports critical listening with minimal EQ adjustments, while its 32-ohm impedance facilitates use straight from smartphones or basic audio gear.
, the Superlux HD-660 Pro 32 Ohms is a practical, value-packed headphone, delivering honest performance rather than luxury, and should be considered by anyone in need of affordable closed-back headphones that perform beyond their price tag.
