> Both the earphones and chargers retail for $19 USD each and since these items are usually cheaper to produce, Apple is saving approximately $35 USD per device.
I'm curious as to where this $35 USD figure came from. I'd be very surprised if headphones/chargers only had a ~8% margin.
I'd (perhaps naively) guess that at Apple's scale, we'd be talking low single digits for wired headphones/chargers.
