Works well.

Comfortable for prolonged use, keeps the noise out and are quite lightweight. They can make you ears a little sweaty in hot weather.

Reduces noise compared to cheaper defenders

Used these whilst working in a joinery company. Would wear them for up to 8 hours a day. They’re so much better than cheap standards ear defenders. They’re comfortable wearing for long periods. Are a solid design and stay in place.They also look really cool.

Noise Cancelling Ear Protection

Excellent Product and works well. Can still hear person talking to you. They need to speak up tho. So, great all round. Comfortable too.The other 3M ones called X5 are slightly better, but too expensive.

Excellent, would definitely recommend and buy for anyone avoiding noise from office, planes, or work.

I bought this as I'm sensitive to noise at work and for long plane rides. It is meant to be a substitute for ear plugs. It works very, very well. The muffs are surprisingly big in size, you will look a bit weird wearing it I suppose, but I'm fine with it. For its size, it is actually pretty light, and feels really light when you're wearing it. The head band is adjustable for most people's head size, mine is pretty big (I had to buy XL bike helmets) but it still fits well with some room to spare. Will work under a helmet as well, maybe not as comfortable but it's still fine, since the head band lies flat across your head, same as the metal cables connecting the muff to the band.The sound proofing is very good, but you can still make out what others are saying, which is a plus. It's comparable to wearing a set of good ear plugs, but way more comfortable for long periods. It's circumaural, so it covers your ears entirely. The muffs press lightly but firmly on your head, creating a seal, but it's not that uncomfortable in terms of the heat and humidity, as good as it could be I guess. I would have paid 3 times more for this product.

Excellent

I bought these for reading at home. As an audio engineer I zone in on sounds all around me and find it near impossible to read in peace when at home with the family. I bought these to drown out noisy neighbors and sound that would interfere with peaceful reading and they have been absolutely brilliant. Waking up and not being able to get back to sleep with noise, these work a treat. Very comfortable to wear for long periods. I even bring them along on holidays if I need a lye in. You can hear nothing with the 38db blocking. Highly recommended if you suffer from concentration issues due to sound in any way.

Big but worth it.

A good friend of mine has these in our studio - and I borrowed them without asking him. We have a drum practice studio and it gets loud in there for obvious reasons. I used them and liked them and bought my own because…Whilst I’m practising the drums I like to have my Bluetooth earbuds in my ears (playing a metronome or backing track for instance) and some other protection over those ear buds, is necessary, whilst I’m Beating the shit out of his drums - I mean, playing his drums lightly with brushes whilst listening to Enya.Seriously though, these are great and I bought them so as to enable myself to have in ear Bluetooth headphones on (in) and have these over the top of my ears to drown out my overplayed china cymbal involved blast beat groves practicing for wedding gigs, without uncomfortable pain.These make your drums sound awesome.Save your ears.Seriously.Buy these.Ps…Look in a mirror whilst wearing them and pretend you work on a runway on an aircraft carrier! You can pretend to be “that guy who works on an aircraft carrier who points in the direction of war to the pilots driving the planes”. (Bill Burr).Paraphrase.
