Pros: Heavenly midrange, sparkly highs, well-rounded bass, exceptional soundstage, Vocals are sublime, These were made for the cello, Detachable cable
Cons: Bass is muddy at times, bass-transients are not the best, not for fast paced-music, Housing falls apart so easily (happened to me and many others)
These earphones possess a truly unique midrange. They make some instruments (such as the cello) sound better than they actually are. Vocals sound rich and warm with incredible body. These may not win in the "most-detailed" or "most-neutral" earphones/headphones category, but they sure do win in the "best-midrange" one. I am hard-pressed to find any headphone that produces a smoother midrange than the SM3's. I previously owned an LCD-2 Rev. 2 who's midrange was very liquidy and detailed; but they were still not as fluid as the SM3's midrange. These are truly special earphones with a special sound.
