I bought 2 types of Eargasms; the slides and the ones with the flange (Electric Jungle -Gold). They are both equally nice and work wonderfully. I will say however the slides have taken me some time to get used to using and understanding. I think its really just user error on my part lol The instruction manual was very tiny for me to read and I mistakenly thought there was supposed to be a right and left ear plug with the slides, but each plug is unique to be universal for right or left no matter which ear you choose. So now that I understand that and the idea that the slide moves forward or backward depending on how much noise you are trying to reduce, it all makes sense now. It might not be this complicated for everyone. lol I did reach out to customer service and they were very helpful and I also watched a couple tutorial videos I found online. For being only my second type of ear plug I have purchased in the last couple years, I cant say that I know much about any of them really, however these are super comfortable to wear and they really do work! I just did my research and finally found that these would be the best for me. I was right. I was worried about getting the two different types but glad I did, now I have options depending on where I go and what I do. Overall my experience with Eargasm has been wonderful all the way around. Thank you!!
