I wonder is how meticulously "calibrated" this tech is for "certified" headphones, and how much that makes a difference. They talk about first party headphones and any others that become certified like they'll be the ideal pairing with the Amp, but I find it hard to believe you can get a better experience from the SXFI Air than you can with a pair of DT 770 Pros and an SXFI Amp. I'm sure any certifying they do will be done in-house, so this just sounds like a shameless money grab to me. Of course, a proper sound card will undoubtedly be the way to go for this kind of thing, whenever they get around to releasing one. They're supposedly using machine learning to improve their algorithms over time. However, the SXFI Amp is probably the best way to early adopt. At least I think it would be. It would be nice to hear from someone with both the Amp and the Air, or at least a good comparison between using the Amp with certified headphones, a pair of uncertified headphones from that list, and a pair of quality headphones that aren't listed.
