At this point in time, I'd really be interested in a wireless dac/amp. Fiio and NuForce already have wireless DACs... but they really need to do an all wireless setup, like the Mixamp 5.8... but audiophile level. I would love a wireless E17 with the power of the E12.
Sorry, just rambling. Just getting tired of clutter. Cable management is the future of audio for me.
Functionality wise, the A50 was perfect. It had the convenience and features I wanted out of a headset but overall SQ was lacking. Boomy bass, mediocre mic. The comfort was ok at best.
What I really want is a wireless version of what I use now, AKG K702 65th with Beyerdynamic mic. I basically wish I could take the SQ of the AKGs and Beyer mic and combine it with the A50. That would be the end-all, be-all for me IMO.
