I think you are confusing a license to use "enterprise edition" yourself, with a "license to provide the product (as a service) to customers", as is required under SSPL.
SSPL is not AGPL: you can never be sure you comply with "or make your code available" due to the way this is worded. Please read https://www.ssplisbad.com/ before arguing that it is the same as AGPL.
My partner uses noise cancelling headphones with adjustable levels of noise cancelling for this. She used to have a WH-1000XM4 but I'm not sure if that one had different levels, she currently uses a Quiet Comfort Ultra where the "outdoor" mode is not only resistant to wind, but also blocks slightly less noise when she's inside.
