Trustedreviews posted a comparison review between the Sennheiser PC155 vs Icemat Black Siberia
Both headsets have a single cable running from the ‘phones into a volume control with the Icemat's being detachable. Small things differentiate the two products here: the Sennheiser's volume control is basic but functional, with its mic on/off switch and volume dial, whilst the Icemat with its reflective black box is stylish but overly minimalist with its lack of a visual indicator for the volume level.Sennheiser PC155 vs Icemat Black Siberia
