What does the i stand for in the new SR225i from Grado? Improved, that’s what! Features are the same as the SR125i, new driver, cable and housing designs, but this headphone has an increased rear air flow, utilizes Grado’s larger ear cushion and has closer matched drivers. Air flow is increased by 50% which is achieved through an improved rear metal screen. The use of closer matched drivers and the larger cushions results in an enlarged soundstage, while the improved rear screen frees the headphone from colorations.

HI-FI Choice Recommended

"Sounding very good at both low and high levels, these headphones are of reference quality both for the classical virtues of neutral frequency response and low coloration, as well as for their clarity and the high degree of listener involvement envoked." HI-FI News & Record Review / Martin Colloms

"The SR225s sound unlike any other headphone. They have an amazingly solid presentation, packed with weight and presence. There is also a pleasant richness in the midrange that benefits all types of music." WHAT Hi-Fi

"When it comes to classical music, the Grados reproduce instruments with both believable timbre and solidity. The treble boosts fine detail and no hint of agression. ... these Grados are hard to beat!" WHAT Hi-Fi
