I don’t have a problem with wireless headphones when it comes to mobile devices. It sucks, and I wish I still had a headphone jack, but I’ve kinda come to peace with the fact that wireless accessories for phones are apparently the future.
However, I wish there were “mid/high-end” Bluetooth/wifi cans. All the wireless headphones are either earbuds, IEMs, or overpriced Skullcandy/beats/Bose/apple/etc. I want an AKG or Audio-Technica pair of wireless headphones that go over my ears, and I want an option between closed-back and open-back headphones. I prefer closed-back due to the sound isolation and I’m annoyed that there’s a price gap where it’s hard to find closed-back headphones in the $300~$600 range.
…or at least it was when I checked a year or two ago; everything with a closed back was either entry (<$100), low-level (<$300) or too expensive (>$600 + $100 or more for an amp, because at that price range most headphones need one).
Edit: oh yeah, and a optional balanced cable that uses a standardized connector, like miniXLR
