After 20 years of using a set of Grado SR125 headphones, I finally upgraded to the SR325e. The difference is subtle, but very noticeable. The highs are very clear and articulate and the bass is tight and focused. I look forward to even better sound as these get broken in. I debated on spending the extra dollars for a new set of phones, but the price is well worth the difference. As I age, what I notice in the music I listen to has changed, but these headphones allow me to enjoy things I cannot with my main stereo system. I listen to classical music, jazz, classic rock from the 60's and 70's, a lot of fingerstyle guitar, and finally contemporary christian worship music. These headphones allow me to hear all the instruments (some that I had not heard before). From the timber of a tympani drum to the chime of a triangle in an orchestral piece, every sound is clear and precise. My dollars were well spent. And I appreciate that they came with an 1/8" plug for my iPhone and iPad as well as a nice gold adapter for the 1/4" plug in my sound system and mixer board for our worship team. They are very versatile. The only change I would make would be if they came with a nice carrying case. That would be icing on the cake.
