Good unless you're laying down?

I got this for an overseas flight but I've already used it to sleep at home a couple times. I think on a flight it would be great, but laying in bed you can definitely feel the speaker pad against your ear and it's not comfortable.

I seem to rest better, but it is not as great as I thought. I still turn my pillow during the night, so not sure it is cooling like I thought it would.

Pretty good. Unfortunately I sweat like a... well use your imagination. Im a pillow flipper and didn't  notice this  pillow staying cooler than any others. The pillow gets... lumpy is best way to describe it. Again... I sweat a lot.  I throw it in dryer to fix said lumps. It gets 3x thicker. couch cushion thickness.  Neither are fun for a side sleeper. You will drown in pillow unless you sleep on edge. Edge gets lumpy. Repeat. And on and  on.

It has a good quality but it is not good for listening when you want to sleep. If you want to have a good headphone with a good price it is a good choice.

Really had high hopes for this as my head is always flopping down when I fall asleep on the plane and it was endorsed by a blog. The pillow has to be wrapped very tightly around your neck in order for it to stay erect for your head to lean on it comfortably. If you have a window seat, you can use the window to lean on and it works a tad better but if you don't like the choking feeling around your neck, this is not the pillow.

Well, it improves my neck support, but does not make it that much easier to fall asleep. Still need a pillow to lean against. Worth the price.

This pillow is nice and always stays cold, but it is rather firm. I only use it to prop me up to watch tv in bed. Too hard on your neck to sleep with. But good back support if you need that!

Only used it for a two weeks to listen to music to fall asleep. I've got a bad back, and don't move much during the night. So I didn't put a lot of wear on these at all. One night tho, when I put them in my ears, one side barely had any sound coming out, in spite of where I had my volume settings on my device. I even switched sides, cuz maybe it was my ears... nope. :(  Disappointing - they're super comfy, but not durable enough for gentle-to-regular handling.

Like the pillow, but you can't sleep on it every night because it will get too soft and unsupportive. After a night off, it has great support. Maybe buy two and rotate! Solid value.

Pretty good and comfortable enough for side-sleeping, but they have to be pressed against your ears to hear them at low volume so I can only hear out of the ear I'm lying on... if I turn them up any higher, my wife can hear them too!

This isn't as comfortable as some of the reviews raved, but it's definitely sleepable. Better than an air mattress, worse than a couch? I think with a mattress pad it would be really nice! Does fold up really well and stows out of sight, fits under half of my queen size bed or in a closet. Good price, good sleep!

I must have a different idea of firm... but a pillow that allows my head to sink right through to the bottom doesn't qualify as firm.

They are fantastically soft and fluffy though :) I throw a thin hard pillow underneath and I'm good to go :)

Bean bag chair is of good quality but the fill is too soft. It's good for laying on but if you try to sit up like in the pictures it just flattens out under your back until you're lying flat.

This is a nice pillow but to be honest, there's too much filler in it for my liking.  I think the head should generally lie in alignment with the body for spinal integrity.  Whether that is sleeping on the back or side this pillow does not "give" as much as I would like. So, while laying on the back or side, my head is tilted upward and out of alignment.  The quality is there but I suspect they either need to come out with a softer pillow or one with less filling.

a little noisy, but if you like sleeping with noise, good for you.

I bought these for two reasons:  1.  One review said you could sleep in them.  2.  The were billed as noise isolating.

They are not noise isolating.  This is bad for blocking out my wife's snoring at night.  On the other hand, it does make them safer if you walk or jog outside -- you can hear traffic, etc.  They do give a nice sound, however.  As for sleeping in them, yes.  The lie flat and close to the head so if you sleep on your side, they are still comfortable.  I gave them to my daughter for working out and walking.  She seems to like them.

Bought this to help me fall asleep on those nights I couldn't fall asleep, and it works well - so if that's what you have in mind, you will be good to go, on the other hand, it could be kind of boring to sit & watch for too long - I'd say your happiness with this item will depend on your motivation for buying it.
