I have a Tune Belt that I really like. I have the one that fits the Note 3 without a big case:

But they also make one big enough to fit an otterbox defender:

I love mine and have never had any problems with it. The phone stays in without problems and the headphone jack faces out the top. There's even a cord wrap to keep the the wires from going all over.

I've had several tunebelts and they are great for larger phones or phones with bulky cases. The material is stretchy and I've never had one accidentally press the buttons. It is also machine washable :)
