So I currently have the Crossfade II and am looking for a new listening experience. I'd considered Fostex, but I don't really want to lose bluetooth functionality. I listen to music 3ish hrs at min daily, but a good chunk of that is running or gymming, wires are just too clumsy for me ergonomically speaking. I like the idea of Nuraphones as someone with Aspergers, but I worry I think they'll sound worse than my current set up. Kind of like how I felt the Sony 1000XM3 were just a marginal upgrade at best. Any thoughts or recommendations for me? Appreciate the input in advance.
