Conclusion: Though the CX300 can’t compete with other canalphones we have reviewed, clocking in at half the price, and with unmatched comfort, the CX300 comes out on top for value. The unique hybrid design of being part canalphone, part ear bud will appeal to those who find traditional canalphones uncomfortable.
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.
