5 was definitely too big. Pros: comes with the sport wireDoesn?t attract dirt like other silicone casesCons:The back doesn?t cover top entirelyThe front covers a little too much. Not very substantial for the price The instructions were clear and had sufficient pictures. there was a weird second while flipping through that I found a sticker of some random anime character, BUT THERES STILL SO MUCH NARUTO ???? Y?all this sandal is so dope, it fits perfect not to mention the delivery time wow it was on time, and most of all I love the brand. The audio is far too quiet to hear anything effectively when plugged in to an Xbox controller(my primary reason for purchasing these). They would turn on and immediately turn off right after charging. Plus they were coming apart in the back. I did not test it on an aeroplane but to me, it is really good (and GBP 100 cheaper than the model with ANC).
