Durable with good noise protection

Durable and good performing ear defenders, been used for work 5-6 days a week over 1 year and still good. Dropped on the floor a few times(≤ 5) and no noticeable damage, only once it felt like noise attenuation in left ear wasn't working anymore but nudged it a few times and adjusted the cup over my ear, something clicked and it worked again.The deep ear cups help against heat and if you're so inclined ear buds fit inside, although comfort may vary.Probably should had bought a hygiene kit 3-6 months ago but that's still good value if you're using it for work and better care can be taken at home to avoid replacement.Still can hear people talking if that's a requirement but going forward they will be replaced by 3M Peltor X5A, at least for home use.

Comfortable and Durable

Brilliant for autistic individuals. Very comfortable and the adjustable feature is helpful. Can easily be worn to help aid sleep or to make things less overwhelming in public. Used constantly for over six months and still as good as the day they arrived. A tad pricey but completely worth it for the quality and level of comfort.

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.

Ear defenders with adjustable headband

These ear defenders are comfortable to wear and are perfect for noisy machinery.One reviewer said that they are rather small and wouldn’t someone with a bigger head, well they are adjustable as described on page 3 in the manual.I would recommend them and they fit any size head.

Comfortable ear defenders that are well made.

Comfortable and effective for a small head

Comfortable for a small head and very effective noise reduction, but doubtful will suit a larger head so well

Great at sound reduction

Amazing at compressing down the sound, and great ear protection. It would be nice if the top is a bit more comfortable but still really nice
