Design and features:Although this portable ear-insert model lacks active noise reduction, the earplug-like design 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 even with lower-powered portable audio devices. The BDH653 has an inline volume control that works with iPads and some iPod and iPhone models, plus an integrated microphone and player function controls that are compatible with iPads, some iPods, and some iPhones and some other cellphones. The call connect/disconnect button can be used with some iPhones and some other cellphones. These earphones may not operate properly with some non-iPod players or other audio equipment. This model comes with three pairs of earpieces of various sizes, and a storage case.
Sound quality: We found the BDH653 delivers good overall sound quality, with a warm character. The pronounced bass has good impact, but it's blubbery and lacks definition. Midrange is constricted and dark sounding, and gets a bit crowded by the bass. Treble is sizzly, and upper treble sounds cut off. Overall sound is closed in, with so-so dynamics.
Comfort: We found that these earphones fit and stay in place with no problem, but they produce a sense of pressure in the ear opening that might be uncomfortable for some.
