Grado's Signature S750 earned a reputation as one of the best audiophile headphones available, full stop. The S550 takes that same house sound and brings it down to a price more people can actually justify.

## The Family Resemblance

Grado headphones have a distinctive character: open, detailed, unmistakably Grado in a way that's hard to describe to anyone who hasn't heard the line before. The S550 carries that signature sound down from the S750, without simply being a stripped-back budget version.

**Spec callout:** Positioned below the flagship Signature S750 in Grado's lineup.

## The Price and the Spec Sheet

In Australia, the Signature S550 lists at A$1,449 through Grado's local retail network, well under half the US list price of the flagship Signature S750, which is priced at US$1,695 overseas (Australian pricing for the S750 has not been officially confirmed). Both models share the same fundamentals: a 50mm dynamic driver, an open-air design, and cabinets built from Brazilian walnut rather than the aluminium Grado reserves for the S750.

## Where the Two Diverge

The S750 uses Grado's newer S2 driver, built around a carbon-fibre and paper composite diaphragm, and Grado quotes a wider frequency response of 4Hz to 48kHz against the S550's already broad 6Hz to 44kHz. Both run at 38 ohms nominal impedance, but the S750 is noticeably heavier at 460g against the S550's 335g, a difference you feel over long listening sessions. Each ships with a detachable cable terminating in a 4-pin balanced mini XLR connector at the headphone end, with the S550's standard cable running to a 3.5mm plug (6.3mm adapter included) and balanced 4.4mm or 4-pin XLR options available at extra cost. Both come fitted with Grado's B-style cushions as standard, though they're compatible with the brand's full range of S, F, L and G cushions for tuning the sound further.

Grado hand-assembles both headphones in Brooklyn, and the resemblance in construction is deliberate: the company has pitched the S550 as carrying the S750's engineering down to a lower price rather than as a separate, lesser design. Both headphones also ship with a driver-matching tolerance of 0.05dB between the left and right channel, a detail Grado quotes on its own spec sheets as evidence of consistent quality control across the Signature line, and both are rated with total harmonic distortion under 0.2 per cent at 100dB.

## Who It's For

This is a headphone for people who've heard Grado's higher-end offerings, wanted in, and balked at the price. It's not trying to be an all-rounder for commuting or noise cancellation; it's a dedicated listening headphone, and it knows exactly what audience it's speaking to.

## Verdict

For anyone building a home listening setup who's been eyeing the Grado house sound from a distance, the S550 is the entry point worth taking seriously.
