UPDATE: Noopl 2.0 removes the need for acoustic coupling as audio is transferred to the iPhone via the Lightning connector. Noopl 2.0 includes cosmetic spacers you can use if you'd like to fill any gap between the top of the Noopl device and the bottom of your iPhone.
- Remove the pre-attached rubber coupler from your Noopl device by pulling up gently on one side. Once that side is loose, pull up from the other side. Then, slide the coupler off of your Noopl
- Inside the Noopl box beneath the top tray you will find three slots with additional couplers designed for phones without cases. Select the coupler that matches your iPhone model.
- Attach the new coupler to your Noopl by pushing the pegs on the bottom of the coupler into position on your Noopl.
- Attach Noopl to your phone. The Noopl Listen app will start, and you should follow the on-screen prompts.
