Try a legit Apple dongle, as in don't buy it from Amazon as there's fake/mixed up/etc. stock in the warehouses. Like buy it from a physical (Apple) store in real life.

Like search up the ridiculous situation with microSD cards on Amazon. They mix the third party storefronts and official Amazon stock all the time. It's so sad and so it's better to buy things like microSD cards from Best Buy or a physical store/retailer. As otherwise you'd get fake microSD cards and all that.

For the ~$10 Apple dongle, just note the reduced power if it's the EU version, or the apps needed on Android to bypass Android's DAC/etc. system in order to get the best capabilities.

No need to really spend more than that, but look into well-reviewed dongles with physical volume control if you think you need an amp/DAC/etc.

Here's a bit more info on dongles (with physical volume control) and static/hissing/buzzing/et cetera: https://www.reddit.com/r/HeadphoneAdvice/comments/100lh5a/dac_for_new_mb_asus_and_new_headphone/j2icwxm/ and https://www.reddit.com/r/HeadphoneAdvice/comments/zn88xs/help_on_iems_pc_usage/j0fns20/

But yes it could earwax/etc. clogging up the filter and nozzle of the IEM. See here for how to maybe fix it: https://www.reddit.com/r/headphones/comments/yzkk5e/how_to_remove_ear_wax_from_iem_without_damaging_it/ix13bpo/

Basically use 90+% isoprophyl alcohol but make sure the IEM nozzle is facing down as you don't want alcohol to get inside and possibly damage the coating/drivers/etc. behind the nozzle/filters/etc. And then wait several minutes for it to dry, better to wait an hour or so for near certainty that everything is dry.

Look into the AZLA SednaEarfit MAX Standard if you want to maybe delay/prevent those earwax/moisture/etc. issues. AZLA SednaEarfit MAX Standard is basically the only silicone ear tip that has an integrated wax guard. Some foam ear tips have that, see the black Shure Olives foam ear tips.

Here's more info on how to avoid/delay the condensation issues with the Olina, Chu, or most IEMs that have condensation issues: https://www.reddit.com/r/HeadphoneAdvice/comments/uznoqi/my_chus_broke_after_a_day_of_use/iadlxz5/. This has more info on the Moondrop Spring ear tips.

Basically for the future, just use a clean paper towel or microfiber cloth and wipe your ear tips and IEMs after each use. That should prevent/delay the clogging/condensation/etc. issues. It's just a problem with certain IEMs, more so the ones with metal outer shell designs. And if you live in a humid area or produce a lot of body heat.

This is how you should use Etymotics or really any IEM or TWS earbud to make sure you have that good/perfect fit for that vacuum seal (necessary for the bass to be properly produced): https://www.youtube.com/watch?v=8KwXEqe6Gq4

Try Etymotics, they beat top of the line ANC from Sony/Apple/Bose/etc. The noise reduction/isolation is great, make sure to use Comply P foam ear tips or Comply T(x)100 foam ear tips before giving up.
