iPhone 7 no more supports the old 3.5mm headphone jack. This was done to reduce the number of ports on the bottom of the casing and make the device more compact. It is now replaced by a single lightning port for your headphone which is also used for charging your phone.
The problem with this arrangement is that you can only do any one of the following task. Either charge your phone or use your headphone. You can’t do both simultaneously. In most cases, it is possible to stay away from using earphone while charging. But at times, it can be an inconvenience especially for power users. Here is how you can do both at the same time.

Bluetooth headphone technology has advanced lot. The latest headphones come in a wide range of shapes, sizes and prize. Find one with a decent sound quality, comfort to wear and good battery life.
The only problem here is to keep your headphone charged as it runs on battery power. A decent quality headphone is capable of retaining its charge up to 20hrs.
