I like them a lot, due to working well to block sound, they're comfortable & decent quality, especially for the cost.

I have a noise sensity issue that can cause me dizziness especially when the noise is high pitch or even running water has caused me severe dizziness. I wear these to brush my teeth and do dishes. they work so good i cant wear them to watch tv but if you need to cancel noise such as in plane or high noise places these are perfect and I am so glad I bought them. they feel a little tight but I think that is the purpose in order to get the noise reduction.

I got these so I can wear earbuds underneath in hopes they are better than my noise-canceling headphones for eliminating chatter and TV noise in my house. They are!

The ear cups are very deep and can fit a quarter with extra space (see photo). These fit my Soundcore Life P3i and Soundcore Life A1 earbuds. Those are 2 very different-shaped earbuds, so I think they will work with nearly all buds. Both buds have extra space and are just as comfortable as wearing these ProCase earmuffs without earbuds. My P3i earbuds have a stem that's slightly shorter than some AirPods.

I mainly got these to improve focus and cut out chatter from my family while learning programming and reading. These block enough sound that the TV, podcast, conversation, etc. can be going strong in the same room and I can reduce about 80-90% of the noise with these alone. Add earbuds and some light music and I cannot hear any talking outside at all. This is what I expected from over-the-ear noise-cancelling headphones + music, but those did not live up to the promise. Maybe super-expensive headphones would do the trick, but I will not be trying that on a whim. I would guess these + earbuds underneath are about 10x more effective for blocking out voices than most noise-cancelling headphones. These + noise-cancelling earbuds would probably be even better, but I have not tried them!

Comfort for very long durations (2-8 hours) is exactly as I expected. These are too tight around your head. Since I am not using these for safety, I stretched the headband out a bit and this reduced the discomfort (at the expense of effectiveness and safety).

Removing unwanted wooden work table in the garage. It was very well constructed and connected to a common wall with the house interior. Hammering a crowbar between the wood 2x4 studs was challenging since there were at least three 10-penny nails aunt each joint. Metal to metal tool contact was noisy and continuous until separation was achieved. Hearing protection worked as well and better than expected.

They came wrapped well and they are so comfortable. They are very well fitting and do cancel the noise. We use them in construction: Masons cutting stone using large saws, vacuuming the job site using Shop vacs, Carpenters using table saws and routers , etc. This was such a great purchase that we decided to buy some for our adult children too. The value is here. Protecting your hearing and getting the job done all in one. It was great to purchase these and for them to work even better than expected.
