I don’t know how to rate this - it doesn’t fit the hole my phone case has for the charging port (which is of a similar size for all the other phone cases I’ve used), and the only way I can use this is to partially pull my phone case off near the port. The width of the plug grip is definitely larger than the apple lightning ones, I’ve checked.
But at the same time, the feeling this gives me know that I can wear my favourite headphones and charge my phone at the same time if needed is a relief! Music is very important to me, and helps me stay focused and/or tune out as needed (something that I can really struggle with thanks to my anxiety), and past experience with old phones that needed to be charged regularly, meant that having access to a headphone jack and lightning port was a must have! - Seriously I cannot overstate how important this is to me.
Since I don’t know how to rate this I decided to give it a middle score, since looking at how annoying it is to actually use this with my phone case make me objectively rate this a 1, but the feeling of relief this gives me in knowing that I can always have access to my music (even when charging) is beyond a 5!
