Etymotic ER20XS-SMF-P High Fidelity Reusable Earplugs [Polybag], Ultra-Compact Comfortable Hearing Protection for Concerts, Festivals, Sports Events, Sleep, -20dB even volume reduction, Standard Size

So I have the ACS ER-20's, also known as Etymotics Ety-Plugs which are very well known and recommended. I had a problem with the fitting of these in one ear only, I had to push them in too deep it was uncomfortable. So I ordered these in large size hoping they would help.Their profile is much lower than the Ety-Plugs so aesthetically they are superior. The comfort, for me anyway, is also superior - they don't need to be pushed in so deep as the originals. They stilll don't come as comfortable as wax / foam but they sound just as good as the original model which are highly regarded for live music. The fitting is fine for the duration of a concert but I wouldn't want to wear them all day long. Of course all ears are different but these are designed pretty generically so you have a high chance of getting on with them.If you have no previous experience with live music sound protection I would recommend these as a first try. They are probably as good as you will get for this price margin, although obviously they won't come close to custom moulded ones. They are designed by a highly professional and reputable hearing specialist so you can rest-assured be happy with the safety and sound quality they provide.

Fantastic noise cancellation. I intend to use these for concerts and sound production/engineering purposes. They’re a great fit and size for my personal needs and fit nicely on my keys. Fairly comfortable and easy to remove.

These are totally awful. Tiny fiddly little things where down-sizing and cost cutting has gone mad. They are painful to wear and still feel like they will fall out. The noise reduction amount was rubbish. Not safe to use for me drumming. It said (when I bought them) 20db reduction but in the packaging it says (in massive letters, 13db). So, they are incorrectly described, utterly useless and no way worth the money I paid. The box they come in is irritating to use, you squeeze the corners so that the side opens. It doesn’t close fully after opening either. it looks like a little box with a lid, but it’s not! There is no seal made, so any contaminants could get in there and mess up the plugs before you put them in your ears. The case is so small there is no way it won’t get lost. The case comes with a thread-like chain that is so thin I would not trust it to link it to a belt or key ring.I have returned them and bought Alpine Musicsafe pro instead - I can’t fault them.

I bought these after losing my pair of EarPeace music ear plugs and I was very impressed with the quality of the sound - it's strikingly close to having nothing in your ears at all, reducing all the frequencies by reasonably equal volumes; certainly much better than the EarPeace ones in this regard. They also have better noise reduction and fall out of my ears less easily than the EarPeace ones if I smile or swallow too much. The one place the EarPeace plugs have these beat is the comfort - these have three "prongs" and go into your ear canal quite far, making them a little painful at times, whereas the EarPeace plugs only had two prongs and felt much less painful.Overall, I would highly recommend these, but they take some getting used to on the comfort side of things and inserting them can be a chore.

Size were too small for adult ears, did not create a good seal in ears. Not sure if the xs stands for extra small. I thought they were a regular size.They probably work very well in the right size ear.

Good earplugs! Compared to the foam ones, the sound is much better, you can follow a conversation without problems even in noisy environments. The NRR is not the best, for example in the theatre or in concerts it can still be a bit loud, so I'd recommend another model. Comfortable, very easy to insert and remove and discrete, nobody will notice you're wearing them. A good choice for noisy (but not super loud) places or just to isolate yourself for the environment.

Have been using for gigd, concerts and even theatre shows to enjoy the misic

I only use these for concerts and they are great for that. Noise level becomes even and it does a good eq balance of the sound. Only downside is that they get uncomfortable to ware after about 3 hours, so I would never use to sleep or something that took longer than a concert
