bluetooth adapter for QuietComfort 15 headphones

[bmorris]

I was looking at getting the QuietComfort 15 headphones b/c they block out sound so well.
Is there a tiny bluetooth adapter I can attach to the headphones since the aux cable detaches?

Looking for like a micro Bluetooth adapter that uses a headphone jack.
