Closed-back studio headphones
The Superlux HD-660 Pro is a pair of closed-back circumaural headphones for studio applications that, despite their affordable price, deliver a surprisingly wide frequency response which extends from 30kHz all the way down to 10Hz and thus clearly surpasses the normal range of human hearing. Superlux promises a precisely detailed sound and a balanced frequency response, allowing the user to evaluate signals with pinpoint accuracy. In addition to the HD-660 Pro itself, the scope of delivery also includes a 3.5mm to 6.35mm stereo jack adapter and a carrying pouch.
Superlux's 150-ohm model
The diaphragms of the Superlux HD-660 Pro headphones are driven by powerful neodymium magnets, and the drivers, which measure 40mm in diameter, produce a maximum sound pressure level (SPL) of 92dB provided that the headphone amp used is powerful enough to handle the headphones' 150-ohm impedance. For users who intend to plug into headphone outputs with significantly less power on tap, Superlux recommends the 32-ohm version. This model will deliver a much higher level of volume when combined with smartphones, tablet computers, laptops, and smaller audio interfaces.
For mix engineers, gamers, and podcasters
Thanks to their closed-back design, the Superlux HD-660 Pro headphones are a superb choice for recording artists, but podcasters will also benefit greatly from their high level of sound isolation, which means less sound leakage into the microphone during recording sessions and thus a welcome reduction in the amount of post-production work required. Livestreamers can also look forward to a much higher level of monitoring volume, and gamers who prefer to use a tabletop microphone rather than a headset mic and enjoy the game's audio right across the frequency spectrum. What is more, mixing engineers can capitalise on these headphones' detailed sound and balanced frequency response, while DJs can concentrate fully on their set without distractions.
Anyone looking for microphones and headphones with an excellent price-performance ratio will certainly find what they are looking for from Superlux. The company employs experienced specialists and produces its articles at various locations in its own factories in China and Taiwan, where the products are developed, tested, and manufactured under one roof. Everything can therefore be manufactured on site, from the raw material to the finished device, which has a positive effect on the selling price. The products are often praised in test reports for their sound and manufacturing quality. With Superlux products, private users can achieve solid recording and mixing results even without a large budget.
Freedom of movement while recording
The Superlux HD-660 Pro features a single-sided cable connection, making it a great choice for recording situations in which musicians with bulky instruments need to move around freely. The headphones' 2m cable also makes them ideal for the studio, where sound engineers have to scurry back and forth. Thanks to its soft velour ear pads and relatively low weight of 323g, the Superlux HD-660 Pro is also made for long hours of intensive listening and gaming. Although these headphones have a lot to offer at an affordable price, users should nonetheless be aware that it is not possible to change the cable.
