A great product for all the music lovers. I have Been using this product for 7 months now and am really satisfied with it.
The sennheiser CX 180 has a comparatively increased headphone senstivity of 16 ohms with its ability to cancel out ambient noise.It has a frequency response ranging from 18 to 20, 000 hz.
Just like every product(inner ear headphone) it needs a 54 hrs burnout time before it can expel its full capacity. Even without that it is the best product at this price range .
With its impeccable in-ear-canalphone design it cancels out any unwanted noises and provides the best bass experience over all mid ranged in-ear headphones.
The only drackback is that its wire isn’t tangle free
