People have given great suggestions but one more thought: if you're a side sleeper, just one earbud in on the side you're not sleeping on. Also I never liked AirPods, they just don't fit well in my ears. Maybe try some other brands til you find one that's more comfortable. (I use JBL Endurance Race, they're still bulky but flatter profile) Also your partner should try an eye mask, and earplugs. You shouldn't be the only one making sacrifices or adjusting your habits so the other can sleep. These are the best earplugs I've tried https://www.amazon.com/3M-Disposable-Reduction-Compliant-S12-71-2018/dp/B008MCU0N0/
