I wasn't aware that you could still buy E3c 'phones new. Are they direct from Shure?

My recommendation is to buy directly from Shure and make sure you get the excellent 2-year warranty. Especially if you live somewhere that gets cold in the winter, go for the warranty coverage because it's likely that the jacket on the wires will split in below-freezing temperatures. Mine split last year and they sent me a brand new pair with a renewed warranty with a minimum of fuss. (I have E2c's)
