At first I thought that the bass was a little boosted as well (but not bloated), but I've come to just love their voicing. It's just about perfect to me.
I compared them to my M50's last night and it wasn't even close. The 100AAP's are just in another league, and really are direct challengers to all of the $400 premium headphones!
As I've said before, Sony hit the ball right out of the damn park with these cans
They're so good, even my daughter approves!
She looks. . .um. . .very confused. LOL. How did you get her to pose so perfectly holding the Walkman and looking right at the camera? LOL. And of course, she is BEYOND precious, like seriously unbelievably adorable, OMG *gushes*
WOW so much hype over 100AAP....
That's because for this price it really can't be beat, mate! Like XERO1 was saying, this headphone is in the same price-class as the ATH-M50x, but absolutely KICKS THE LIVING CRAP out of the M50x in a side-by-side comparison from the same source with decent volume-matching.
Honestly I'd say it combines the strengths in terms of both build and sound, and a similar signature, that were exhibited by the MDR-1A (while eliminating most weaknesses) and the sonic strengths (in terms of detail and clarity, soundstage, etc., but not signature/frequency-response) of a headphone like the PSB M4U1. In other words, it has a pleasantly warm signature with some level of non-overwhelming bass-boost that at the same time
in no way sacrifices mids or highs in the process, while simultaneously getting rid of a good bit (not all, but a good bit) of the bass-bloom/bloat that was evident in the MDR-1A, and also manages to have a smooth and pleasant, never-fatiguing tonality while at the same time having clarity and detail which are absolutely top-notch as far as mid-fi portable headphones go. Not to mention that like usual, Sony is really on top of their game here when it comes to comfort, portability, and overall ergonomics. There's really nothing more I could ask for in a portable set for a price of under $400.
