but unfortunately I get this extremely loud static noise out of both headphones after about a half an hour of use

quality build.-Comes with 4 sets of different size inserts and ear loops, so you have a better chance finding your perfect fit.-The inserts provide great noise isolation without annoying pressure in the ear.-Long battery

Several times while using, I have heard extremely loud noises from the ear buds causing me to nearly collapse in pain

I actually don't mind that part so much, because it can act as a minor active noise cancellation--in addition to the passive noise cancellation that is advertised and performs really well with snug (default for me) ear tips--which is helpful for when I'm in a focused studying mode

The audio quality is decent; however, when it's connected to a device that isn't playing audio, the earphones often emit a sort of low droning static noise

After my last update review of the SoundCore Spirit earphones, where I reported a serious problem with random, extremely loud screeching noise occurring without warning, I was contacted by Anker to resolve the problem

Beside, it makes uncomfortable noise and pressure in my ear when I run.
