My earphones are Earsonics SM3. The ear tips I used previously were the double flange that came with the earphones. These had quite a large opening which I presume is to allow for a brighter, more open sound. However, they were getting a bit old and not holding on the earphone tightly and would fall off when I would take the earphones out of my ears.
I couldn’t find where to buy the same ones so I took a chance on these ones. I was concerned the sound quality would be compromised due to the ‘normal’ size opening on the Got Ears. I cut off the smallest end tip to make them double flange. To my surprise, the sound quality was much improved in the lower end as the tips held and sealed much better than the factory ones! Also, the brightness was not affected noticeably and the gains on the lower end far outweigh any reduction in brightness. Also these hold really tight on the earphone and now the tip stays on the earphone when I remove it from my ears!
