Query: Great headphones!

I bought Grado SR 125 headphones after reading many reviews. I figured they'd be good, but they turned out to be incredible! Every note and instrument is so clear and distinct. Vocals are rich and natural and there is no distortion. Much better than my Bose and Sennheiser headphones! I'm spoiled and don't want to listen to anything else. Well worth the price!
