I have a set...its dangling from the earphone jack of my (first generation) Ecotones machine. I tried it once last year...during Cicada season....took it off during the night because I was getting too warm under it, fell between mattress and headboard and having bothered to fish it back out yet.
I also have the second generation Ecotones unit in my bedroom, along with the Marpac dual level sound conditioner.
I also have a pair of behind the head NoiseBusters (Active Noise Canceling).....which makes for a quite a strange experience.....since I've always had a fan blowing in my bedroom, and it stopping during the night usually wakes me up....(though I have box that beeps once when the power goes out behind my headboard now...)
I've never been able to wear earbuds...
You may be a dreamer, but I'm The Dreamer, the definite article you might say!
