The sky is falling as Apple is rumoured to be ditching the headphone jack in iPhone 7. Aside from the fact it is merely conjecture at this point, the entire planet seems to have forgotten that Apple are unlikely to ditch Bluetooth and, that being the case, instead of lining Apple's pockets you can buy a third party Bluetooth receiver to use with your old headphones.
Sure, this is not perfect - if you are able, use a cable - because of course the Bluetooth receiver costs money and is another battery to charge, another device to pair, another complication in your life (simplicity at Apple died with Steve Jobs?) - but it does make Apple's decision easier to deal with if they do indeed ditch the headphone jack and you really want to keep hold of your old headphones (I'm quite attached to my iGrado pair for example).
Actually, it's a TRRS jack, and I'm kind of more annoyed that it will render my Røde Smartlav+ microphone obsolete without some Lightning adapter or improved Bluetooth protocol inclusion.
There's always Android!
