Design and features:Although this portable ear-insert model lacks active noise reduction, the ear plug-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 with lower-powered portable audio devices. The EPH-M200 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-Apple/non-Android mobile devices or other audio equipment. This model comes with five pairs of ear pieces in various sizes, a mini-plug-to-1/4-inch-plug adapter, and a carrying case.
Sound quality: The EPH-M200 delivers sound quality that falls in the good range, with sound that can best be described as generally full but somewhat congested. Non-critical listeners may find it acceptable for music and movie soundtrack playback, despite some obvious shortcomings. Bass (the tonal region that more or less covers bass drums, bass guitars, stand-up bass, etc.) has good impact and goes deep, but is somewhat prominent compared to the rest of the tonal range and a bit boomy. Midrange (the tonal range that more or less covers voices, guitars, horns, etc.) is somewhat thin, hazy, and congested (think sonic traffic jam). Treble (the tonal range that covers cymbals, the upper range of violins, etc.) is extended, but a bit sizzly (sounds that should have a delicate shimmer are more reminiscent of bacon frying ). While the sound has a decent sense of liveliness it is closed in (lacks a sense of openness, making you well aware that sound-wise you have earphones plugging your ears).
Comfort: We found that these earphones fit and stay in place with no problems and feel very stable even with vigorous head movement, but they produce a sense of pressure in the ear opening that might be uncomfortable for some.
