We got to take a look at Sennheisers newest offering: the HD800. This unit is their new flagship part and even though I am no audiophile: they sound amazing. The materials have been kept as light as possible, while the vibration of the unit has been nearly eliminated, giving you the best possible sound quality. The ear drums are not completely sealed, but give you an amazing soundstage.
You will also find their new portable series, which is intended for the audiophile music lover on the go. The HD218 gives you great sound quality with a normal, but powerful bass, while the HD228 adds further bass. The high end HD238 goes a step further, giving you even more "umpf" for your money.Source: Sennheiser
