I won a new set of Bluetooth Wireless Logitech UE9000 headphones ( http://ue.logitech.c...adphones/ue9000 ) on the 28 Jun 2013. Box is opened and the headphones were only used for a mere 10 mins. My ears started to hurt - may be due to its inability to adapt to the active noise cancelling feature which I experienced similarly with branded headphones like BOSE QC2 (the shop accepted the return) so this is not due to this particular headphone. Unfortunately, it means that I am not able to use this headphones so I am willing to let this go at a lower price of $500 (negotiable). The retail price at the local shop is about $599. Note: I don't have receipt of the product - however, the online warranty with Logitech has not been registered yet. It comes with all the original accessories in the box. Headphones worn for only 10 mins and back into the box it went. Product Features: 1. Awesome audio quality 2. Active Noise Cancelling feature 3. Active and Passive mode (wired) 4. Robust design 5. Comfortable Circumaural (over the ear) earcups 6. Listen Through Button on Left ear cup with volume, Playback/Navigation, Phone control and Power Switch on Right For more - do check out some of the review online. Looking to let go at $500 but you can call 91004922 to discuss. Would prefer to arrange delivery around Clementi MRT / Buona Vista MRT / Jurong East MRT, Singapore. Cash on delivery.
