Unless you own the product and know it has that problem I don’t know why you would invent it out of nowhere.
Can we also acknowledge that this is a general purpose smartphone and not an audiophile playback device? A ton of phones with headphone jacks had/have terrible DACs because they are general purpose devices designed to be good enough for the average person.
Someone who wants an audiophile playback device should buy an audiophile playback device.
yep! i've got a k5 kicking around on my desk, a proper dac is good stuff. they've still gotta make one we can cram 60W through though!
ed: i guess i should add that i just use a pair of bluetooth cans or even bone-conducting set when i am listening to stuff from my phone 'cause it's just podcasts and youtube videos
