24k Gold-plated plug
Rest assured that the precious metal gold finishing on the 
plug will give you a more reliable connection for better 
quality audio.
CCAW voice coil
By using top-quality Copper Cladded Aluminium Wire 
(CCAW) in the headphone driver's voice coil, the sound 
quality is considerably improved.
Neodymium magnet
Neodynium 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
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 by using complicated time delay circuits and 
signal processors. It also makes using your headphones 
for extended periods far less tiring.
15 mm speaker driver
Small enough for optimum wearing comfort and big 
enough to deliver crisp, non-distorted sound, the 15 mm 
speaker driver is an ideal size for listening enjoyment.
Asymmetric cabling system
This simple yet highly effective solution to cable tangling 
works effectivly by enabling you to hang the cable behind 
your neck instead of under your chin.
1.2 meter cable
Th e idea l cabl e lengt h to gi ve you the fre edom t o put y our 
audio device where you want.
Carrying Case
This case is the most convenient way to look after your 
headphones and prevent cable tangling when not in use.
Flexi-Grip design
A soft, flexible part protects the cable connection from 
damage that otherwise would occur due to repeated 
bending.
In-line volume control
Adjust the volume to your preferred level without having 
to go to the audio source unit.
