I'm just selling ONE pair of Sennheiser PXC 350s for $450 or nearest offer.
They are $699 at Dick Smith =\ and $$559.96 inc GST at SoundStore.
There is no warranty, but I highly doubt you will need it anyway.
I've just opened them to see if they work and they certainly do :P
These are genuine headphones and I won them in a competition from a raffle =D
The specifications are:
The PXC 350 is a circumaural high-end travel headphone set with NoiseGard? Advance technology for active attenuation of ambient noise.
The PXC 350 enables an unprecedented sound experience for people on the move, thanks to its adaptive baffle damping in combination with the patented Duofol diaphragms, which prevent unwanted partial oscillation and thus guarantee a highly natural, lifelike sound quality.
NoiseGard? is an active noise compensation system which Sennheiser originally developed for use by pilots, who have to rely on good sound quality and efficient protection against ambient noise even in high-noise environments. NoiseGard?actively compensates the noise, based on the physics principle of sound and counter-sound.
The PXC 350 features the NoiseGard? Advance technology. This technology is a further development of the filter functions used in the original NoiseGard? system, and enables even better active attenuation of ambient noise of up to 85%. It is of course also possible to use these headphones passively, i.e. without NoiseGard? and without batteries.
The PXC 350 is foldable and is supplied complete with a practical transport case, 2 AAA batteries and audio adaptors (double mono and 6.3mm). Volume control integrated in the single-sided cable, which is detachable and replaceable, ensure maximum convenience for the user.
