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 Music Maniac AH-C50MA has an integrated microphone and music 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 four pairs of earpieces of various sizes, 4-contact adapter for cellphones that use non-standard earphone jacks.
Sound quality: We found the Music Maniac AH-C50MA delivers very good overall sound. Bass has good impact and goes deep, but some users might find the bass to be thuddy and boomy. Midrange is lean and a bit grainy. Treble is extended, but pronounced and may sound a bit harsh on some program material. Fairly open sounding. Good dynamics. The overall charactor is mixed - generally neutral to cool, but some users might find the bass warm.
Comfort: We found that these earphones produce a sense of pressure in the opening that might be uncomfortable for some. They may have to be fiddled with extensively to seat them properly to get the best sound quality, but once properly positioned they stay in place with no problems.
