Excerpt: The CX300 marks Sennheiser’s first attempt at the in-ear, canalphone-type headphone that has made Shure and Etymotic famous. While most canalphones are touted as being noise-reducing, the CX300 takes a different angle, creating a hybrid ear bud-canalphone product. Sound strange?
Pros: Custom sleeves for proper fitting; good sound quality
Excerpt: (1 items) The new CX300 are Sennheiser's first entry into the in-ear-canal headphone (canalphone) market. However, rather than take on Shure, Etymotic, Ultimate Ears, and other vendors of higher-end canalphones, Sennheiser is aiming squarely at the popular -- and less expensive -- "canalbuds" such as Sony's EX70.
