I'm getting iCans for Christmas

[hyamaiata]

After taking a look (and listening) at the Sennheisers PX100 and PX200, AKG K26P, AKG K27i and many others i decided i should go for something of higher quality. My choice was the Ultrasone iCans .For me, good means:
- Good bass
- Portability
- Good overall sound quality
- Comfort
- Easiness of use

Would it be worth then buying the Ultrasone iCans considering what i want? Should i really expect high quality sound or just average? Is this what would be expected from Ultrasone? How do this ones compare to the ATH ES-7 considering price and what i mentioned?

Thanks, Santi.
