Thanks both. I just can't decide if I want Bluetooth earbuds or the new Sony noise cancelling headphones (the Sony WX-1000mx3 I think). I'd been all set to get the Sony and wait on the earbuds but I'm sitting at my desk listening to my Grados for the first time in a while and I'd forgotten how much I love the way these Grados sound.

Grado did just come out with a Bluetooth headphone but it doesn't support the AAC codec that iPhones use, which seems like a huge oversight from an audiophile company with presumably a lot of Apple device owners as customers.
