By using top-quality Copper Cladded Aluminium Wire (CCAW) in the headphone driver's voice coil, the sound quality is considerably improved.
Neodymium magnet enhances bass performance and sensitivity
Neodymium is the best material for producing a strong magnetic field for greater sensitivity in a voice coil, better bass response and higher overall sound quality.
Virtual Surround design for a realistic, comfortable sound
This Philips patented 'reflected-speaker' design creates a virtual surround sound effect that gives you the kind of 'out-of-head' audio experience that was previously only possible using complicated time delay circuits and signal processors. It also makes using your headphones for extended periods far less tiring.
