I actually do not sleep well at night and never did since birth. Volume setting it can seem a little muddy but thats always the case when there are no tone controls whatever headphones you have and theyd be little use for music when bass and treble are absolute requirements. If you understand basic DC wiring you cant mess this up. including in rain. Keeps my very expensive Airpods protected, I would recommend. I ordered a M and this was at least a 2X! it literally feels like sleeping on giant, fluffy marshmallows. Dont think of getting this wet unless you like the color blue on everything, including your hands. I had to yell for my husband to help support the weight of the clothes and hangers tumbling onto me. Expected a better assortments.
