I would not put headphones in the same category as built-in speakers.

they're in the same category in that neither is particularly good and
they aren't used in situations where perfect sound matters, such as
jogging, walking or riding on a train or airplane.

Perhaps the average schmuck in a test can't tell, maybe I can't tell,
but in 10 years I will still have clean copies of my music, and my
hearing, which is fine. If you do MP3 at 256k or 320k why not just
record the PCM as a .wav? What is the advantage of using MPEG
compression? H264 aac? Or Apple aac?

the reason to use compressed audio is because it's significantly
smaller than uncompressed audio, with no audible difference.

typically, one can get around 5-10x as much music in the same space or
have the same amount of music with plenty of room to spare for other
stuff, such as apps, photos, videos and whatever else you might want.

why waste the space on something that can't be heard?

and aac is not apple's. it's an industry standard that's better than
mp3.

"Space" is cheap, hearing is not. Perceptual coding is audible to lots
of people who listen for a living. These include musicians and audio
engineers. FLAC is free lossless audio codec. Compression and lossy
compression are 2 different things.

Apple is where I was first exposed to aac. Sorry if I upset you. And you
have obviously never listened to a pair of Grados so I don't know what
to think about your opinions regarding listening to hifi.

Oh drear, another Mr. golden ears.
