Query: Fantastic after correct setup

These earbuds are great but you have to set them up correctly. First, they have to be put into your ear canal not just hanging in your ear. Second, you must use the correct size rubber earbud cover. I initially used the smallest sized ear bud cover because it fit in easily but I was a bit frustrated with the weak bass. After switching to the medium earbud cover the bass was absolutely fantastic. I recommend these 100% and they are infinitely better than standard Apple earbuds. I suggest trying the earbuds on first with the small black earbud cover to get used to inserting them into your ear; then use the mediums for incredible sound.
