I wonder if it still would not be time to figure out reviews older than about 3 years, when the development of these products has gone very, very far since then.
The first impression is that they sit pretty damn weird. Unbalanced in the way that the very fästgånggärnen jumper on headphones sitting too high up, causing the pressure to the head becomes uneven. Not in a way that hurts (this much because they sit pretty loose, especially for a smaller period of use), but rather are the direct uncomfortable due. that it always pinches ate more in half the top of the cushions, while it feels like almost openly in part under the earlobe. So, in practice, these actually a semi-open acoustics "design", given the poor ergonomics. They are also foldable.
The sound I would describe as a muted, with a cloudy base who are happy to take over the music, film and games where it is more present. Speaking of sound, I just want to mention that any of the myriad geniuses at koss chose to manufacture the plastic mic plug in a shabby gray-green, and lurpluggen with black, even though the industry standard for color selection has long been that the mic is pink and the handset is green This is to easily be able to determine which is which, quickly and easily. Just silly to try strömlinja this.
The microphone itself is not only vague, it also brings up every little sound you have currently. The swing arm for the boom-mic is one of the worst I have experienced. Do not just stick it out, and is almost impossible to bend. The "hacks" that stops the arm vertically is quite lax and loose, which means that you move your head with mic arm in the lowest position, or between two positions that offer resistance. will provide audible feedback to the person who hears you, as it bounces something really wild about turning your head. Well, almost like some sort of trampoline.
