SR225x

Awesome Headphones

They sound great ! I questioned how they would feel on the ears, but after using them they are comfortable and don't notice wearing them after a while. Highly recommended

Different headphone amps & different listening experiences

I originally wrote (I'm not sure it actually went through properly) a not very positive review of my experience with my new SR225s (compared to my Sony headphones) while using tube-based headphone amps (all Pete Millett diy construction). I found the sound disturbingly muddied and the brights that everyone complained about were not present at all while the Sonys sounded perfectly fine. I was bummed. So I finished upgrading a jfet solid-state based preamp to use with headphones and now the Grados sound great. I'm experimenting with different foam earpads to see how my listening experience changes. Don't know if the harmonics generated by the tube headphone amps don't blend well with the Grado-built transducers or what. Doesn't seem to bother the Sonys. I'm not giving the headphones a 5 only because the construction of the whole the whole headphone apparatus doesn't really sit comfortably on my head.

Must for Vocal Recording

I needed a pair of headphones for a vocal recording out of town. A preliminary recording revealed some noises and I wanted to make sure those have been resolved on the actual recording day. I read the reviews and the Grado descriptions for each model. I decided to go with the SR225x. I listened to Paul McCartney's Jenny Wren. It sounded good on the SR225x. On the SR325x there was added lower end and on the higher it seemed very slightly brighter. I confirmed this by listening to Robson Jorge & Lincoln Olivetti's Ginga horn section. The SR325x definitely has a wider frequency range and also the soundstage is better. But for what I needed, vocal monitoring, the SR225x did it's job.
