This plug fits through my iPhone 6+ case so I can connect it to various speaker system. The coils at very tight however and tend to pull at my phone which is the only reason I rated it 4 stars instead of 5.

Great little cord - almost exactly what I needed (the 6 foot, coiled, is a little short - I could have used it a bit longer because i really have to stretch it to get it to my phone on the dash in the car, but that's not the cord's fault :-) Anyway good solid quality - and works great.

Bon rapport Qualité/Prix. Par contre, ne s'étire pas facilement.
