Sony MDR RF960RK Headphones

Weighing in at only 9.6 ounces, this Sony headphone is still the heavy-weight champion of its class. I've had mine for about 4+ years now and I can still get Approx 9 hours with fully charged Ni-MH battery (the very ones that were included when I bought it new) or well up to 24 hours when I opt for using AAA Alkaline type batteries; which I regularly put to the test. The range was advertised as 150 metres - I don't measure my steps, but I can wash my car, do some gardening or chase my kids round the house and not lose a word of my song thanks to a superb 900MHz RF FM transmission with its selectable 3 Transmission Channels, a frequency response that lives comfortable in the - 20Hz - 20kHz sensitivity range - and it's got 105 dB/mW Impedance. Plain English? from Mozart to Main stream and hard Rock to Reggae - you get deep soul quenching bass, clear vocal tones and a sweet high trebble that would please any car or home Hi-Fi enthusiast. The way the docking unit/charging base is made is Sony-cool too because the connection chord can be reconnected so you have the red & white (Left/Right) phono ends to use and connect the unit to your stereo - or enjoy a DVD and the Driver Unit : 30mm, dome type then connects back to the unit. In summary, these headphones will not disappoint you - (prices now range from £39.99 or less but I'd still pay the £80 I did back then) - as long as you recognize the limitations of analog wireless technology.
