iPhone 7

Hi

No - it comes with EarPods, which are wired headphones with a Lightning connector.

No. But you can buy one.

iPhone 7 comes with

1. EarPods with Lightning connector

2. A Lightning to 3.5mm adapter

3. A Lightning/USB cable

4. A USB wall power adapter.

Apple's newly announced wireless headphones are AirPods.

They will be available as a separate purchase in due course (from late October, in the US, for example):
