## Questions & Answers

**Q: What's the difference between this er20xs model and etymotic's cheaper "high fidelity" option?**
A: The noise attenuation is the same. Both are "high fidelity" earplugs in that they lower the decibels to a safe level while preserving clarity.Differences--ER20XS can change out the eartips. ER20XS has an option for foam eartips. ER20XS stem is shorter and more discreet. It fits more comfortably underneath hats, helmets and other headgear. Etymotic Research

**Q: I see most reviews used these for concerts/music... How do/would you think they would perform with something such as shooting firearms?**
A: I would not recommend them for shooting a firearm.  These earplugs are great at filtering the sound and reducing overall noise by about 20-30 decibels.  This is not nearly enough for the bang of a firearm.

**Q: Will these stay inserted in the ear if the person is performing/fast moving or will the combination of sweat and movement cause them to fall out?**
A: Let's start with comfort. They are not as comfortable as poly plugs- but, you will get used to them. Watch GP riders before a race. All use urethane plugs.But, I do like them and continue to use them- usually. They stay in a bit better and reduce the noise at lease as well. You own a BMW, you can afford to try them. You might prefer them. Buy a pair.

**Q: What's the difference between universal fit and standard/large?**
A: universal fit gives you 3 different replaceable fittings and is the safest choice if you want a more exact fit. Standard is what fits most people. Large that simply for those that have large ear openings.

I purchased these ear plugs along with the Ear Peace high fidelity hearing protection plugs. I ride a naked style motorcycle and experience excessive wind noise every day. (Despite what they say, all helmets are subject to excessive wind noise at highway speeds, just to different degrees based on design.) First off, these ear plugs look cool. Doesn't really matter in my ear, or under my helmet, but when I have them hanging over my jacket via the provided lanyard they look cool. The first thing I did when I opened the package, after admiring how cool they looked, was try them on. Obviously. They slide in very easily and fit snug - the firm base makes it easy to control insert angle and prevent applying to much pressure and hurting yourself. The little pull tab worked as designed to get the ear plugs out, but I found it a little tricky to get the right pressure to get them to pop out. The lanyard does this for me, and with the string, you get plenty of leverage if you need it. I recommend switching to the lanyard immediately. The fit was very comfortable and the first few time I used them I couldn't help but smile. The amount of clarity that these retain while in your ear is mind blowing if you are used to foam ear plugs. It really is exactly like just turning down the volume of everyday life around you. Some frequencies are muffled a little bit, but overall the sound quality is exceptional. I was worried they would be uncomfortable inside my helmet with the large plastic base. This was a non-issue after putting my helmet on and realizing they are seated comfortably inside the ear and do not stick out far enough to bump into anything. Chatting with people over my Bluetooth speakers sounds great, even at highway speeds. Voices are not muffled or sound out of place. If the ear plugs are not properly inserted you will probably notice a resonance in the lower frequencies. It's not a painful sound but the lower sounds have extra buzziness added to them. Just pull over and adjust the plugs appropriately or even continue to ride - I never found it uncomfortable. These were my top pick between the two, I'd recommend these to anyone looking to try a pair of reusable ear plugs! Nothing but praise for these!
