Design and features:The Hellas has an integrated microphone and touch sensitive volume, music player, and call connect/disconnect controls for use with paired Bluetooth devices. It's headband and ear pads are detachable and machine washable, and it has a reflective earcup connecting cable and earcups that fold for ease of carrying and storage. This model comes with a USB charging cable and a carrying bag.
Sound quality: We found the Hellas delivers sound quality that falls in the good range - it reproduces music and voice reasonably well despite the obvious shortcomings in its sound. The overall sound can best be summarized as nasal and somewhat congested. Bass (as in bass drums, bass guitars, stand-up bass, etc.) has good impact, decent definition, and goes fairly deep, but is somewhat subdued. The midrange (voices, guitars, horns, etc.) is thin, nasal, somewhat grainy, hazy, constricted (think straightjacketed), congested (as in sonic traffic jam), and has a plastic resonance (something like what you would hear if you talked into a semi-rigid plastic cup). The treble (cymbals, the upper range of violins, etc.) is extended, but smeared (sounds that should have a delicate shimmer sound blurred) and uneven - the mid-treble is somewhat prominent while the upper treble is muted. The sound has a good sense of liveliness and is somewhat open (sound-wise it almost seems like you don't have anything covering your ears).
Comfort: We found that these headphones are light weight and produce a sense of moderately light pressure on the ears. The ear pads might feel hot after prolonged use, and some users might find the earpad material to be scratchy or itchy . Vigorous head movements might shake them loose, and incidental contact with the touch controls on the right outer earcup can cause unintentional pausing, track skipping, or volume level changes.
