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 medium-high sensitivity so they can provide satisfying volume levels when used with home audio equipment and even lower-powered portable audio devices. The Street by 50 Sport In Ear has an inline volume control that works with iPads and some iPod and iPhone models, plus an integrated microphone and music player function control 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, a mini-plug-to-airplane-jack adapter, and a carrying case.
Sound quality: We found the Street by 50 Sport In Ear delivers good overall sound with a warm character. Bass has good impact and goes fairly deep, but is pronounced and boomy. Midrange is a bit hazy and dark. Treble is a bit smeared and upper treble is rolled off. The sound has good dynamics, but is closed-in.
Comfort: We found that these earphones fit and stay in place with no problems, but they produce a sense of pressure in the ear opening that might be uncomfortable for some
