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.
