Design and features:This model doesn't include active noise reduction, but the earplug-like design of these portable ear-insert earphones helps to reduce both outside noise and sound leaking out into your environment. The earphones have high sensitivity, so they can provide satisfying volume levels when used with lower-powered portable audio devices. This model comes with three pairs of earpieces of various sizes.
Sound quality: We found the CX 215 delivers very good overall sound with a slightly warm character. Prominent bass has good impact, but is tubby and lacking in definition. Midrange is smooth. Treble is slightly recessed, but has good upper treble extension. Overall, these earphones are somewhat open sounding with good dynamics.
Comfort: We found that these earphones fit and stay in place with no problems, but a sense of pressure in the ear opening might be uncomfortable for some.
