Update:
I am looking at some good quality earphones for Nokia E72 phone and other music devices. The CX 275 is with a mic but i'm not sure if it will work with Nokia E72 or not. The CX 180 are just simple earphones without mic.
Please tell me which ones are good in terms of quality and durability?
CX 275s is the best among cx180, sony s mdrxb30 and 170 mm (sennheiser)
Its your choice among these if you want a great bass and good treble.
Also if you listen EDM then its perfect...
CX 275 I would imagine, since it seems to represent a higher level model :P
Go for CX180, way better then CX275s
