Certainly... Heres where I have managed to settle into things, and keep in mind the following commentary is all relative to the other cans in my list.
Pros- My flattest, driest, most accurate sounding headphone, also has the most layered soundstage. Its my most detail revealing. With complex recordings I am able to more clearly hear the different tracks and instrumentation.
Cons- Sometimes its too flat sounding, too dry/accurate/analytical and boring. Hard to amplify despite its 65 ohm load. Its upper midrange character can sound a bit "plastic-ey" and synthetic at times.
Pros- Warm, soothing, smooth, distant sounding at times in a good way, relaxing, kick back, get lost in the music and soak in the tunes. My most bass-heavy headphone, with the deepest extension. High impedance accompanied with high sensitivity, makes it easier to drive than I was led to believe. Very forgiving with poorly mastered recordings... My go-to headphone in this regard.
Cons- Limited detail resolution. The warm, plump bass presentation can be a bit murky, and has a hard time with musical complexity.
RS1, with modified S-cushion pads:
Pros- Grado slam, punch, energy to the max. You are on stage and in the recording booth with the musicians. Good detail resolution. The only headphone I have used that really sounds like the live instrument played in person (using clarinet, guitar and drums as a reference).
Cons- Intimate, near-field imaging and soundstage. Stock pads are not very comfortable, and take some getting used to.
K240s 55 0hm
Overall- Just a good overall headphone. Jack of all trades, master of none, like a Leatherman multi-tool. Smooth and Balanced sounding across the spectrum, with no real spectral hot spots or dead spots. Good energy and dynamics, good detail resolution. It layers an image and soundstage surprisingly well for a headphone in this price range. It does benefit slightly from amplification, particularly in the bass frequencies which can be a little murky when under-amped. Sounds great paired with my Macbook Pro, and is forgiving with poor recordings. It lacks the detail resolution, image/soundstage layering and overall clarity of the higher end cans mentioned above.
SR60i, with modified S-cushion pads:
Overall- Similar pros / cons to the RS1, but a step down in detail resolution, clarity, instrumentation separation. Can't layer a soundstage image as well as the RS1.... a more "one dimensional" soundstage image. A thicker sounding headphone with less "air" in the ambient elements in recordings. A much more forgiving headphone than the RS1 when it comes to poorly mastered recordings, my fave Grado in this regard. If you're plugging into a Macbook or iPhone The SR60i sounds great and is about 85% of the RS1 at a fraction of the price. Its only when you start amp-ing and sourcing things up when the RS1 starts to really flex its muscle over the 60i.
Hope this helps!!! Good Luck!
