Pros: The ATH-CKM55BK are very detailed sound that brings a very punctual bass sound without being muffled, siding a bit toward clarity. A punctual bass that doesn't muddy any of the mid or highs. I'd say the mids really stand out in front and the highs do not pierce. You get the punch without blurring all the other music even listening to very hard fast music.
Cons: Got it on sale and for the price I can't think of a CON.
Pros: These have the BEST sound I have ever owned, i work nights so these are my most important tool. They adapt to any music i put to them, from 40's jazz to modern dub step, they took it all. the design of the buds allow you to really ram them in your ear and really let the bass out, it takes some hardcore force to rip these out of your ear. Yes i have heard others, and these will out perform any overhead head phone by a mile.
Cons: Their durability for $65 is poor, after daily use of 6 hours for 5 months, and constant warping around my music player, sitting in my cars cup holder and being used and abused, the left bud wiring shorted about a inch from the bud, it was one of those pesky shorts were you couldn't single out trough knotting or otherwise evasive action, so i tried to redo the wiring, i couldn't figure out the type of wire these use, so i just bought a second pair becasue of i only hav...
Pros: These Sonicpro headphones have to be the best I have ever owned. The sound clarity and detail from low, mid and high ranges are the best I have heard to date, even from earbuds selling at twice the price. I am really, really picky when it comes to over the ear or in the ear headphones.
Cons: Not really a con, but the cord on these headphones are really well built; thus, a bit thick and need some time to break-in properly.
Pros: The phenomenal Highs Mids and Bass of these little buds is truly impressive. The have an outstanding clarity and separation. I can hear the instruments on stage as if I were standing amid them, the buds accurately portray the mellow sound of R&B as well as convey the high intensity energy of even my most demanding techno and rock. I can't say enough about the sound these little ear buds put out. A purchase well worth the money. I also own a set of over the ear closed ...
Cons: I see no real cons unless you can't get one of the 4 size of buds to accurately fit your inner ear. I tried all 4 and found that the mid created the best seating and seal to give coherency and bass response.
