Prince of Persia Z
I still use iphone earphones to listen to music. Wired earphones are still better.
I knew they were better back then. And I knew they'd be better for awhile...
But it's been almost 10 years. We've been through multiple Bluetooth version updates, new streaming codecs created solely for audio transmission and quality, not just data transmission, bandwidths increased, more stability, longer range, latency reductions.
Like I would expect after 10 years of iteration, Bluetooth would have got within 95% the experience than with a wired set, but it's not even close... I feel like it's 80% the way there, but that 20% is still so very noticeable.
It can also be my "mp3 player"
I'm using the term mp3 player loosely, but it's really one of those fancy media players where the first thing they advertise is their DAC chips they use for "audiophile grade quality" and other marketing fluff like that.
I received it about a month ago and been using Bluetooth cause I couldn't be bothered taking my headphones off the wall. But I finally ran out of battery mid-listening session. And oh my lord everything is sounds so much more cleaner... But that might also be because Bluetooth sets have to carry the battery in them and they're amplified by that powersource, so theres basically no filters or capacitors between the power and the speakers.
Through a specialized built player, the electricity powering my headphones is going through larger capacitors and a longer wire, and the audio I'm listening to went through a higher quality DAC
Like I already knew all this for years and it's still obvious when I explain it to myself, I just thought with almost 10 years, there would have been a smaller quality gap between wired and wireless by now.
