I got the leather case in black. The saddle brown looked great, but I'm not that baller. First time I've had a case in 17 years of owning a cell phone. Initial thoughts are that it is unobtrusive. The leather isn't great quality but seems to get the job done.
Also I've had zero issues using the adapter with my Shure headphones. It's tiny enough to fit in the case which the headphones came with. Not sure what all the fuss is about. Doubt I'll get Bluetooth headphones until something matches the sound quality of the Shures. The adapter is a perfectly viable solution day to day.
Honestly, return the black and get the saddle brown. It's a sweet color combo with the black iPhone. But beyond that, the saddle brown wears beautifully and develops an amazing patina.
