Excerpt: I was looking for earbuds that sound good, that didn't have the bells and whistles like iPhone mic or inline controls that get in the way, and were compact and low profile enough to wear under a full face motorcycle helmet. These fit the bill in every way. The price was right as well.
Pros: Comfortable, Compact, Good Bass, Great Sound
Summary: Earlier I had a similar lower version of this headphones and they served me well. There is enough noise cancellation and the cable is quite strong against abrasions. The old one lasted about 3years. I notice that the sound quality has improved in this compared to my old one.
Summary: It's a bit difficult to explain exactly, but there is clear difference in the sound between CX 215 and CX 180: CX 215 clearly better. If you can afford to pay twice (Rs ~ 2000 vs Rs ~1000) - go for 215.
