[QUOTE="Steerpike, post: 275565, member: 807"] Indeed Onyx! Interesting to see there that Philips made electret headphone transducers, something that seems to have vanished entirely from current available headphone technology. Or are there still some being made? (For those that don't know the technology, and electret is an electrostatic transducer, with a permanent electrostatic charge imposed on the diaphragm during manufacture, so no external high voltage polarisation is needed.)
