I received the 9waves from mike not too long ago. I must say these are very special earbuds, Soundstage and instrument accuracy is very well placed, the bass is nice and tight, but nowhere near as deep as the as-charm. These are very good at putting the music in your face and making sure you can hear the songs with great detail. Comparing these to the as-charm, ok3, mx760...these by far have the best detail. The mx760 has good detail, but they sound a bit veiled. When you pop the 9waves in, if feels as if you just took off a curtain over the sound and cleared things up.
The as-charms are just fun to listen to because they sound very warm and bring music to life with their deep bass. However, the charms are a bit distant sounding and do not have a great representation of highs. The 9waves are sparkly and i would say almost grado like and seem to work best with rock, jazz, and acoustic music
Comfort: I would rate the yuin = charms, mx760 > 9wave. The 9waves are not as comfy as the others in my ears, but they are very light and can be worn for hours If i'm not walking around.
Overall, I say these are great earbuds and I can't comment on how well they can compare vs the mx980 (The Top Dog) because I don't own them. If you're looking for a good earbud with great sound separation as well as clarity, then these are for you. If you're looking for a punchy fun sounding earbud, I'd go with the as-charms.
