Just order a from Apple Store.  Notice that the model number is MA850G/B instead of MA850G/A I bought before.  Is there any difference in this?
 
I used MA850G/A before, sound is crap with no bass, BUT, after change the earbud with Comply T-140, it is terrific, can compare with UE with price over $150
 
Thanks very much!

They should sound the same. IIRC, the rev.A's filter caps are too easy to get loosen so Apple makes a rev.B with a tighter filter caps. I think the rev.B also has a better 3.5mm plug, but I am not sure.

The difference is just ehe filter cap? no difference in sound?
