Yes, ditching earbuds for heavy-duty headphones will get you a better sound. Yet, you can't really beat the former for blasting jams on the go, and if you're rocking some of the best wireless earbuds, like the Anker Soundcore, chances are you'll be happy with the sound reproduction. Problem is: sound quality is often subjective and what works for the majority may not work for you. So, how do you get the best sound possible from your Anker Soundcore earbuds? This feature tests your hearing and creates a sound profile with a custom EQ curve that should (at least in theory) work perfectly for your ears.
