Ive struggled with this for years... The best option I've stumbled across is this: https://www.amazon.com/dp/B06WWFYCSG/ref=cm_sw_r_cp_apa_glt_fabc_XPQGAWA45KSA51G0X4CT

I bought this year's ago for its intended purpose, and actually grew to love it for my neck (laying flat with that clip cinched tight stretches my neck in a way that nothing else can). Because of this I never left the house without it. I've found myself on several camping trips where this was my only pillow, and clipping the bottom (while not around your neck) actually makes for a reasonable normal (not around your neck) pillow. The first time I tried this I noticed I could hear better with my good ear down in the neck hole, and nowadays I keep this amongst my bed pillows and use it fairly regularly to hear better. I also have proximal benign medial vertigo, so it is difficult for me to lay any way other than good ear down and sleeping through alarms has been a major problem ever since I lost my hearing in college. It's not perfect for this, but certainly something to consider.
