littletree76 0 Report post Posted September 23, 2006 The portable headphone was bought from Audio Technical head office in Singapore 10 months ago and still in perfect/clean condition. Original sale receipt and packaging are available for inspection (original price SGD120.75). It is used with iPod nano at home because it can be driven directly by portable player without amplifier for its high sensitivity (109 dB/mW) and low impedance (36 ohms). The headphone is highly adjustable to suit user's head, can be folded into compact size and carried along in a provided pouch. It is a light weight small close type headphone yet still come with big driver with good frequency response. Followings are the technical specifications: Type: Airtight Dynamic Driver: Diameter 40mm, Neodymium Magnet: CCAW Voice Coil Output Sound Pressure Level: 109 dB/mW Frequency Response: 10 -- 25,000 Hz Maximum Input Power: 100 mW Impedance: 36 ohms Weight (without a cord): 66 g Connector: Diameter 3.5 mm, Gold-plated Stereo Mini-plug Cord: 1.5 m, OFC, Y-type Accessories: Pouch Asking for SGD70 to recover some cash for new headphone amplifier as it was hardly used. Genuine buyer please call 94810866 for further detail. Audition before deal is sealed can be arranged. Please bring your own portable player loaded with your favourite music for the audition otherwise you have to make do with my iPod nano.
