Grado launches S150, its most affordable Signature Series headphones at $295

Design and pricing

The S150 is priced at $295 / £295, making it the most affordable entry in Grado’s Signature Series. The company describes the earpieces as featuring an "all-new single-piece housing design" with modernized styling that maintains the brand’s unmistakable identity.

Unlike higher-end models such as the Signature S750 ($1,695), HP100 SE ($2,495), and Signature S950 ($2,195), the S150 is positioned as a more accessible option without sacrificing core Grado design principles. The headphones retain the brand’s open-back architecture, a hallmark of its audio philosophy.

The S150 also includes detachable Signature Bronze cables with 3.5mm connections on each ear cup and a 6.3mm adapter, offering flexibility for different audio setups.

New driver and features

The S150 introduces a newly developed 44mm S driver, derived from the technology used in Grado’s higher-end HP100 SE and Signature S950 models. This driver is designed to deliver a balance of performance and affordability, targeting listeners who want premium sound without the flagship price tag.

Alongside the driver, the S150 features a padded leather headband, a departure from the brand’s traditionally minimalist approach. This addition aims to improve comfort for longer listening sessions, addressing a common critique of earlier Grado models.
