According to a company press release, US headphone manufacturer Koss is introducing three new headphone models—the QZ900, its fourth generation noise-canceling headphones; the CC_01earbuds, featuring a unique adjustable custom fit mechanism; and the KDE earclips, which employ two transducers per ear and which offer a distinctive on-ear/in-ear design.

The release says that the fourth Generation QZ900 ($250) is smaller and more comfortable than its predecessor and provides passive attenuation and exceptional sound quality whether the active noise cancellation circuit is activated or not. The noise-canceling circuit can be activated with the flip of a switch located on the base of the earcup. The headphones operate on a single AAA battery, which can last up to 60 hours. The QZ900 features a removable signal cord and can therefore provide listeners with some welcome peace and quiet, even when music isn’t playing.

The release continues by saying that the KDE250 ($250) is a Dual Element Clip Stereophone that provides two specially tuned transducers per ear. The KDE250 has a 13mm side-firing transducer that fits in the ear to provide crisp, clear mid and high frequencies, and a 20mm transducer that sits outside of the ear and provides high-impact bass response. The side-firing transducer comes in different lengths and can be angled to ensure comfort and proper fit. Additionally, the metal ear clips that keep the units in place can be adjusted upwards or downwards via precision-machined knurled metal thumbwheels that are provided on each earpiece.
The release goes on to say that, like the KDE250, Koss’s CC_01 earbud ($150) provides some never-before-seen design innovations in comfort and sound quality. The CC_01 features “a unique internal design” that, with the turn of the Comfort Fit dial, allows the ear cushions to expand (or contract) to conform to the user’s ear canals. This is an exciting feature considering that a properly snug fit is essential in order for earbuds to provide maximum noise isolation and appropriately powerful low bass response. Competing earphone makers often provide two or three sizes of eartips to help users achieve a good fit, but the CC_01 is arguably the first in-ear headphone to offer continuously adjustable eartips that can be dialed-in for a “just right” fit for most any user.
