“Sound great, can't expect more from an in-ear headphone... but they're so badly constructed that mine's broke after 2 months. Cheap plastic everywhere and a connector that broke after 1 week. This headphones are a scam. Bought them to replace my old MX500 that lasted for 5 years, unfortunately Sennheiser is not what it used to be. ” --jagalan
“ Introduction The easiest way to explain the Sennheiser CX-150's is that they do what you can reasonably expect. You can't really expect much from a pair of sub-50 dollar IEM's, and frankly, I was pleasantly surprised by the general quality of the CX150's.

“ I count myself really lucky. I was convinced that these phones were too treble-ey and didn't have good bass. I tried some after market foam pads and the bass just came pouring out of them. This led me to experiment further and found that the black foam pads that came with them gave a very neutral, but full sound. I am very glad that I didn't write a review before because it would have been...” --Sam Edwards
