Superlux is a Taiwanese audio manufacturer founded in 1987, headquartered in Taipei with production facilities in Taiwan and China. The company spent its early years as an OEM supplier to major Japanese electronics brands including Sony, Kenwood, and Sharp before launching its own branded products in the early 1990s. That manufacturing background shapes its identity as a maker of budget-priced headphones and microphones aimed at musicians, producers, broadcasters, and home studio users.

The headphone line is anchored by the semi-open HD681 series and the HD668B reference monitor, both of which became widely recommended picks among budget audiophiles and beginner studio users for offering a relatively neutral, detailed sound at a very low price point. The microphone catalog spans dynamic vocal mics like the D108 series, large-diaphragm and small-diaphragm condensers, drum mic kits, ribbon models, and the ECM999 measurement microphone used for room correction and speaker testing. Superlux also produces headphone amplifiers such as the HA4D and a range of accessories for live sound and recording.

The brand is often associated with affordable alternatives to well-known studio reference products, and its mics have been reviewed in outlets such as Sound on Sound for their CMH8 small-diaphragm condenser series. Superlux products are sold internationally through retailers including Thomann, Musician's Friend, and Markertek, and the company positions itself around the tagline "Value in sound is our core belief."

Superlux Audio has 28 products cataloged on Equipboard, including Headphones & In-Ear Monitors, Dynamic Microphones, and Condenser Microphones. Their gear is featured by 4 artists, with the strongest followings in Rock, Metal, and Electronic. Notable users include NIVIRO, Tomi Joutsen, and Connor Carbon. Most Superlux Audio products sit on the budget-friendly end of the spectrum.
