Now the sound, the most important thing:
The sound is very clean, nothing about strikes or scrapes. The highs are clear, the bass is sufficient for me, at least the levels of bass wealth are not in favor as just modern severely curtailed. The deleyCON Sound Marketers S8 go because exactly the opposite way, too much bass that no longer sound the heights beautiful. The problem have the AKG fortunately not.
What the AKG definitely missing is the fullness, my Sennheiser CX300 II sound fuller both the highs and the bass are better resolved at the Senn hoarse, you just hear more details in the voice and the tones are different and spatial, it shows especially if you change the equalizer presets, doing at the Mountain itself hoarse because right thing, change the settings in the AKG not so much on the sound.
So I stay with the Sennheiser CX 300 II, they just sound beautiful although the middle a little scratch.
If I Orignal Headset from LG G2, which would use Quad Beat 2, I would go just to the AKG when the Quad Beat 2 were broken and I would like to have a clearer sound.
Please do not misunderstand, the AKG have K323XS A here really comparable only with good InEars, which differ only in details. Each headset usual supplied the AKG clearly superior.
