iPhone 6 plus camera mount, with buckle clip for action cam attachments.

I designed this attachment so I could securely fasten my phone to my body mount. To achieve a first-person point of view perspective shot, position your phone inwardly with the camera lens facing outward. This setup works flawlessly. You can also use it in conjunction with the headband mount, but personally, I found it awkward to wear even though I used it to create a review video with my phone. It still made me feel a bit eccentric.
