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.
The Grado 325e headphone is among my favorite ever. They are so clear in the highs and Mids, and the Bass is never overblown. The way the drum sounds when it hits with the325e is the way I truly picture it was meant to sound. I am a 50 year old guy who grew up on Rock.. I appreciate these headphones making things sound better than they ever did back in the day..yet sounding accurate. I have bassy earphones too for some of the more modern music.. but the Grado is always my go to for most music I listen to. I hear more with these than I ever knew was there. Highly recommend.
