Sound quality: We found the Fitness Earbuds delivers sound quality that falls in the very good range - it reproduces music and voice very well although it does have some noticeable sonic quirks. With the sound mode is set to Balanced Sound and Awareness Mode is off (as received state of the earphone) the bass (as in bass drums, bass guitars, stand-up bass, etc.) has good impact and goes deep but is a bit prominent and somewhat boomy. The midrange (voices, guitars, horns, etc.) is a bit thin, etched (a bit more sharply outlined then it should be), and congested (think sonic traffic jam), somewhat grainy, and can be a bit crowded by the bass depending on source material. The treble (cymbals, the upper range of violins, etc.) is extended but is a bit prominent, dry, smeared, and sizzly (sounds that should have a delicate shimmer have a sound reminiscent of bacon frying). 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 and does a decent job of recovering room ambience. Mixed character; warmish bass with coolish midrange and treble. The overall sound can be summarized as somewhat bassy and a bit sizzly.
Comfort: We found that these earphones produce as typical of in-ear models a sense of pressure in the ear canal opening that might be uncomfortable for some. Users with small ear bowls might find that the earphone body feels bulky in their ear bowl, but that they will stay in place during casual use and are very stable even during vigorous head movement. Users with medium and large sized ear bowls will probably find that this model stays in place with no problems for casual use and that they are very stable even during vigorous head movement. Incidental contact with the touch controls can cause unintentional volume level changes.
