They get better when an EQ increases the high frequencies.
I can recommend the 1more E1001 triple driver for a similar price point but better sound.
For sound quality I have a pair of in-ear B&O but they are falling apart after a couple years which is pretty annoying because the sound quality is really good.
* the sound quality is utterly rubbish compared to some alternative wireless pairs*
Compared to airpods?
I would pick Airpods over Shure, but they don't fall in the $99 category! I was replying on the basis of a specific model and made it explicitly clear that an alternative pair meant either a foray into slightly expensive pairs (still cheaper than Airpods) or go all the all way to the bottom, for the more adventurous.
Shure has jumped the shark. I own these and have stopped endorsing them, the sound quality is utterly rubbish compared to some alternative wireless pairs, which might cost a little bit more, but even a punt on some of the cheaper pairs like Airdots et al. would be worth it.
