Ok. So it seems like nothing has been sorted out by the new firmware.
I'm not terribly interested in getting into discontinued products and work-arounds that may break as I don't have any existing equipment and everything will be purchased new. So question to the group: (i) Momentum plugged into DS4, OR (ii) Astro A50.
At the moment, I have a Momentum that I got price-matched so it's the same price I can get an A50 for. I am assuming (and if anyone can confirm, that would be great) that the Momentum into the DS4 is how Sony thought people would use the jack (with smart phone headsets) and that the mic and volume levels are good. If anyone has used their Momentum on a DS4, any feedback would be appreciated. I'm mainly curious if you can mute and if the volume controls work. If it does, I don't see how the Sennheiser Game Zero would be a better buy as I prefer no boom mic.
From a sound experience side, it comes down to Dolby Surround vs. better stereo. But I can't test either of these since the return policies are less than generous (no open box).
A50 - $150 for the amp/surround functions, $150 for the headphone quality
Momentum - $399 (in Canada) for headphone quality.
All my other headphones don't have mics and the "add iPhone function to existing headphone" solutions are all a bit of a mess of cables or overly expensive for IEM (if there is a solution to add mic to Heir 5.0 type IEM that would be great but those cables are expensive!).
I figured with the Momentums, I could add a wireless dolby solution down the road when more widely available (although not sure if the integrated mic/headphone plug will work or if you will need a splitter to 3.5mm x2).
