Sennheiser have employ their own “Eargonomic Acoustic Refinement” technology to shape the headphones in a way that delivers audio very directly to the ears, without bleeding excessive amounts out to your surroundings. The ear cups also have an “open design” which is supposed to keep your head and ears cool and comfortable when used, and by all accounts, they have succeeded completely at this. The PC363D headphones often score at least 9/10 across all categories when reviewed, and unlike many are said to be extremely comfortable and do not make you very hot during extended use. The soft material used is Sennheisers “XXL velvet ear pads”, and the headband is cushioned with the same soft material.
There is a high quality braided, fabric cable and the headset comes with a two year warranty from Sennheiser.
