Design and features:This model has a detachable cord with a built-in microphone and remote with volume, music player play/pause and next/previous track, and call connect/disconnect controls.
Sound quality:We found the Penta Driver In-Ear Headphones - P50 delivers sound quality that falls in the acceptable range - it reproduces music and voice reasonably well despite the obvious shortcomings in its sound. The overall sound can best be summarized as a bit thin and somewhat grainy. When positioned so it provides its best sound quality the bass (as in bass drums, bass guitars, stand-up bass, etc.) has good impact but is a bit prominent and boomy and doesn't go deep. The midrange (voices, guitars, horns, etc.) is a bit thin and congested (think sonic traffic jam) and somewhat grainy. The treble (cymbals, the upper range of violins, etc.) is extended but the upper treble is a bit prominent, sizzly (sounds that should have a delicate shimmer have a sound reminiscent of bacon frying), dry and papery. The sound also has a good sense of liveliness and is somewhat open--sound-wise it almost seems like you don't have anything plugging up your ears. This earphone does a decent job of recovering room ambience in the upper midrange, but ambience recovery is so-so elsewhere.
Comfort and Fit:Many users may find that it takes some futzing to get these earphones into place and that this model is difficult to position to get the best sound quality.
As typical of in-ear models they produce a sense of pressure in the ear canal opening that might be uncomfortable for some.
Small
Users with small ear bowls and ear canals might find that the earphone body feels a bit bulky in their ear bowl.
Most users will probably find that once properly positioned the earphones will stay in place during casual use and are very stable even with vigorous head movement.
The sound of the earphone connecting cable rubbing on clothing may be heard through the earphones by some users depending on the clothing it's rubbing on.
