Grado Labs SR125x: open-air headphones with classic Grado energy

The Grado Labs SR125x is an open-air dynamic headphone from the Prestige X line, built for music lovers who want a lively, detailed and engaging sound without moving straight to a higher-priced model. Positioned as the more affordable sibling of the SR225x, it keeps the focus on speed, clarity and musical involvement across many genres. Its open design is best suited to quiet listening spaces, such as a dedicated hi-fi corner, desktop setup or relaxed home environment, where spacious imaging, natural vocals and the distinctive Grado midrange can be appreciated without outside distractions.

At the heart of the SR125x is a 44 mm fourth-generation X Series driver tuned specifically for this model. Grado specifies a dynamic transducer, open-air operating principle, 20 Hz to 20 kHz frequency response, 98 dB SPL at 1 mW and 38 ohm normal impedance, with drivers matched to 0.1 dB. The redesigned driver uses a more powerful magnetic circuit, a lower effective-mass voice coil and a reconfigured diaphragm to support efficiency, reduce distortion and preserve harmonic character. Together with the polycarbonate housing, this creates a clear, expressive and full-bodied presentation.

The Grado Labs SR125x can be paired with a headphone amplifier, DAC, streamer, integrated amplifier or suitable headphone output, making it a flexible choice for a focused home listening system. Its redesigned 8-conductor cable features a braided exterior and super annealed copper wire for clean signal transfer, while the leather headband with added cushioning and S cushions support everyday comfort. Keep the headphones dry, store them carefully and replace the cushions when worn to maintain fit and performance. Choose the SR125x to experience open Grado sound, practical build quality and hand assembly from Brooklyn.
