I have CX180 comparing this with CX180 I would say: Build quality: Sony wins Sound quality: Prefer Sony (appropriate proportion of base and clarity; CX 180 a lil bit driven by clarity compromising lil base) Plus point: This has mic too but CX 180 do not. Durability: CX180 don't even last 3 months. One side stopped working in 3 months though I had repaired it I was not satisfied with the durability. But this I've to wait and see but it feels durable. Price: Sony wins. So you decide.
