Headphone icon on display of iphone Why is there a headphone icon next to the battery % on my iPhone display and how do I remove it ? I haven't seen that there before
iOS 10.2 uses the headphone icon in the status bar (previously used for W1-enabled devices only, like the Beats Solo3) for every Bluetooth headphone. 

When wireless headphones are connected, iOS 10.2 will show a headphone icon and battery level in the status bar.

I am still figuring out if you can turn if off. Will update my answer.
