And most modern phones do not.

Also most noise cancelling options still require the battery, particularly active noise cancelling, which is what Sony uses, and why their noise canceling is so good.

Further certain use cases of the Sony headphones are require the use of the Sony headphone app (which I think they recently changed the name of) and once your battery is dead, or the app is depreciated, those will just be "pretty good" headphones, which you all need some kind of adapter for if you can even find the correct adapter, to use them on a device that doesn't have an audio out.

That said I am a Sony A/V nut. That is a good product, it's just not a lifetime product. Digital A/V equipment tends not to be.
