: Soundstage, punchy bass, mids, comfortable, lightweight
: separation and detail could be better, grainy highs, short lead
These are underrated on headfi, I find them to have an airy wide soundstage with a warm bassy sound signature. They have a warm midrange, 70's jazz with electric piano sounds wonderful. Treble is not that smooth but is just right in the mix, extension is good. You cannot pin-point instruments with accuracy though due to the sound not being very detailed and focused although it is very adequate for the price paid. I will be selling my Philips shp8500 because the Koss have a warmer midrange and airier soundstage. I think they have a unique sound of their own due to the midrange tone. The bass is quite punchy and was a pleasant surprise when I first heard them, although sub bass is nothing to shout about.
What? Warm mids are caused by elevation in 150-800 Hz.
