Settlement Proposed in iPod Class Action Suit

An anonymous reader writes "A court has conditionally approved a settlement in a class action suit brought against Apple Computer by several consumers who claim their iPod batteries did not live up to the company's representation, according to AppleInsider. The tentative approval was handed down by the Superior Court of California for San Mateo County and covers all consumers who purchased a first-, second-, or third-generation iPod model on or before May 31, 2004 and experienced 'battery failure.' According to the published settlement notice, 'battery failure' is when 'the capacity of an iPod's battery to hold an electrical charge has dropped to four hours or less of continuous audio playback, with earbuds attached, with respect to the Third Generation iPod, or five hours or less of continuous audio playback, with earbuds attached, with respect to the First Generation iPod and the Second Generation iPod.' The deadline for filing a claim is September 30, 2005."

I don't know where you get your information, but that is wrong. The lowest impedance I've seen in headphones is 16-ohms. Most portable headphones are 32 ohms to 120 ohms. The iPod earbuds are about 80 ohms. Also, not all high end headphones are the same impedance. Some are as high as 600 ohms, though those are mainly older models. Sennheiser's HD-650, their top-of-the-line dynamic headphone, are 300 ohms, Beyerdynamic's flagship DT880 is 250 ohms, Etymotic's flagship model, the ER4S, is 100 ohms. Grado Lab's high-end headphones (including their $700 flagship model, the RS-1) are all 32 ohms. Sennheiser's earbuds (considered by most audiophiles to be some of the best cheap earbuds currently on the market) are 32 ohms (MX-x00 series).

Also, lower resistance does not necessarily equal less power because while it does take less voltage to drive lower impedance headphones, it require more current. Really low impedance headphones start running into problems with portable players not being able to supply enough current, and most moderate to high impedance headphones run into the problem of not getting enough voltage from portable players.
