Love magnetic connection
The magnetic connection is fantastic! I love this snap on snap off system. I use this tip to adapt my existing phone charger to my phone which is great, and also to connect my USB-C headphones to my phone. I bought the headphones specifically to snap on and off my phone, which narrows it pretty much to the Samsung ones as pretty much no one does USB-C headphones! Samsung ones are great though. Maybe I'm the only person in the world to do this - use USB-C instead of bluetooth.
The power LED in the adapter is blindingly bright, I have no idea why. At night it kind of lights up the room when charging my phone, and if watching something on my phone with said earphones in, the light shines brightly in my eyes. I found a small piece of blu-tak jammed in the hole works great though - dulls the light but still can see it! Or I just flip the adapter over so it faces away. This is the only downside to this adapter, pretty minor one.
Finally - instead of a fixed adapter, a short flexible adapter lead would be great for my phone solution. The adapter acts as a bit of a lever and is a little easier to disconnect compared to one of the USB cables.
