An interesting review, and it was much expected that cheaper earbuds would probably do a similar job. There are some minor drawbacks, but still for those who can’t afford $5,000 these may be quite liveable.
On the Android side of things, the Samsung Galaxy Buds 2 Pro look like a good choice as a first foray into hearing enhancement. The company recently rolled out an update that offers higher levels of amplification for its Ambient Sound option, which passes and enhances outside sound before it reaches your ears.
