But were they actually better?
Sharp 1-Bit Digital Audio
I say "supposed to" because I think most people should take audiophile claims with a grain of salt AND with some perspective. Some people simply don't care if a certain type of setup or equipment adds some esoteric audiophile qualities like "timbre" or "non-recessed mids", they simply want music to sound (gasp!) fun and enjoyable.
You will hear some "naysayers" that say you shouldn't/can't use a "standard" TRS jack with Sharp Auvi 1-bit portables because it will "sound terrible"/"collapse the stereo image"/"damage the device", etc. I can attest to the fact (A-B testing the same headphones/IEMs with balanced/unbalanced cables) that "normal" headphones work just fine and still provide some stereo imaging. Now, I didn't go get a test track of R/L audio and sit an anechoic chamber, but I did test, verified it sounded acceptable, and continued to enjoy my music. I suggest you do the same.
