The Grado sr225e are still easy to power, allowing them to work well with nearly any device. They are very clear and revealing, allowing you to hear the improvements from better sources and music file quality easily and clearly, so using good quality music source and dacs make for a better listening experience. The foam pads are easily replaceable. They are open back headphones, so they leak music and do not block background noise, meaning they are meant to use at home. 1 year warranty in Canada.
From Grado Labs: This headphone has sizable rear air flow through a metal screen, while utilizing Grado's larger ear cushion and closely matched drivers. The result is a broad soundstage free from colorations. The way the SR225e's driver, cable and plastic housing move air and react to sound vibrations is virtually unaffected by transient distortions.
