Audeze Mobius - SO tempting, but theyre only *technically* wireless in that you can connect a device via bluetooth. These are super cute, but don?t fit as advertised. You have to scratch the wax off or maybe scrub with a cloth. For sizing, if you have two people working out at the same with an active class like F45, I think the 10x6 is the smallest Id go. These selling tactics will lose you customers and credibility. I was surprised I don?t look frumpy in a size small, I?m not exactly as small as I once was and it still fits nicely. That being said, these are REALLY nice headphones. Good, true fit. These are very comfy. so had to return it.
