Shure HPAQA1 Threaded ¼" Adapter

The Shure HPAQA1 is a threaded adapter that converts the 3.5 mm stereo plug found on many professional headphone cables to a standard 6.35 mm (¼ inch) plug. It gives you a quick, secure way to connect Shure SRH240, SRH440, SRH840, SRH750DJ, and any other headphone with a threaded mini plug to mixers, audio interfaces, amplifiers, or home stereo receivers that use the larger jack.

In a studio, the adapter lets an engineer move from a laptop or tablet to a console without changing headphones. A DJ can step up to the booth and lock in a solid connection that will not shake loose when cueing tracks. At home, it is an easy solution for listening through high-impedance headphones on a hi-fi amplifier.

Gold-plated contacts protect the signal path and resist corrosion, so your audio stays clean after countless insertions. The threaded collar keeps the connection stable even when the cable is moved or twisted, which helps prevent sudden dropouts during critical listening or recording sessions.

The metal housing offers long-term durability yet the adapter stays small enough to slip into a pocket or case. Whether you are an audio professional who needs dependable gear every day or an enthusiast who wants a reliable link to high-quality playback, the HPAQA1 is a simple tool that earns its place in your kit.
