Features are the same as the SR125 but, this Headphone has an increased air flow by 50% which is achieved through an improved rear metal screen and closer matched drivers. The result is an enlarged soundstage achieved from closer driver tolerances, while the improved rear screen frees the headphone from colorations.

| "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 |
