I have also also AKG Headphones and keep for ages and have incredibly good sound. Since I on good music playback on the move would not renounce and not always wanted to lug headpones, I also bought the AKG K328 In-Ear. Workmanship is excellent and the Iphone control works tadelos. At first I was a bit disillusioned by the sound, but then I found out that I just had to turn around, so right headphones to left and left to right. Then they fit well and much better if you have it relatively fixed in it is the sound optimally. Bass is very pleasant and mids and highs outstanding! Who jeodch more on bass emphasis, for example. Those who prefer House or similar listen, I would personally recommend Sennheisser because this bass are intense. I would buy the AKGs again :)
