Effective at reducing external sound I'm not sure what to expect, but I expected a bit more for the money. These are basically earphone buds that block external sounds. There are no electronics in these ear plugs. They are just passive ear plugs with a mechanical slider to adjust the sound blocking level. You have 4 levels of sound blocking and the highest level does do a good job of blocking sound. I found them as effective as the standard foam ear plugs you can buy. The form factor is good too. They don't protrude from your ear, so are comfortable to wear when sleeping. When you are sleeping on your side, you do not feel any additional pressure. The buds are comfortable in your ear canal too. I like that these are reusable and you can swap the size of the buds for the best fit. However, I do think they're a little expensive for what they are.

Classic ear plugs At the time of writing this review, the price is £40.00. These ear plugs feel sturdy and well made, with the brass construction giving them a premium appearance. The four protection levels are useful because the amount of sound reduction can be adjusted for different situations rather than completely blocking everything out. They fit comfortably and are compact enough to carry in a pocket or bag, making them practical for concerts, travelling, studying or noisy environments. Once fitted correctly, they stay securely in place without feeling excessively bulky. Overall, they are a reusable and versatile option for anyone wanting adjustable hearing protection in a durable design.

For those who want less distraction rather than silence These are for turning background noise down, with four different settings, rather than eliminating sound completely. The lowest setting (15dB) gives a mild reduction where you can still hear your surroundings, and the highest (24 dB) substantially muffles surrounding sound and noise. Keeping some environmental sound can be useful when studying or commuting. I am not sure there’s a big difference between the four settings, but I do find that the highest setting muffles music and allows me to still hear speech. They are comfortable to wear and convenient to carry around. The cost does seem on the high side, though not outrageous.

Doesn't block sound, but turns the volume down. I was all prepared to really hate these earplugs but having tried them I have to admit I'm actually quite impressed with them. The only sticking point is that price, as £44 seems a bit exortionate. That aside, these work really well. The first thing to realise is that these are not really hearing protection. I work in a noisy environment and wear those cheap disposable plugs at work and they are rated to aound 60SNR. They pretty much totally block all sound to protect my hearing. These plugs don't do that, and are not rated anywhere near high enough to be usable in industrial environments. They do conform to EN352, so they are genuine article, but the SNR level is too low for using them for serious hearing protection. But, that's not what they are for. These plugs don't block sound but what they do instead is turn it down. You can still hear normally but the volume is turned down. You can have conversations with them in and still be aware of your surroundings but everything is just quieter. If you work at home with other people in the house, or you have an open plan office where it seems everyone has to shout at each other, or noisy neighbours then they are absolutely brilliant. Every intrusive noise just fades away to background and you can concentrate on what you're doing. They come is a rigid plastic case to keep them safe and there are set of different plug bits for different sized ears. You put them into your ears and the wing part tucks behind the folds of your ears to keep them in place. They are tremendously comfortable and assuming you're picked the correct sized plug you quickly forget you are wearing them as you don't have that 'closed off' claustrophbic sensation you get with noise-blocking plugs. There is a plastic slider on the outside that you can move to three different positions to adjust the amount of sound blocking. I could barely detect any difference between the different levels so I'm not very convinced of the usefullness of this but its fun to play with. They look good too, the brass and white plastic making them look more like jewellery than PPE. I'm really surprised at how useful these are and how effective they are too and I'm wearing them as I type this to block the racket coming from someone mowing the lawn four doors down with the worlds noisest petrol mower. I can still hear them, but they appear to be mowing quietly which is lovely. That price though, ouch...
