I have a melon on my neck, but nothing that would be considered abnormal, Im just a big guy at 67". Even though I had to size up, I?m glad I did. I can?t use them while cycling but they?re perfect for using a single earbud while driving. The big kid size 6 is about a mens size 6, womens 7. I bought it for my daughter in year 6. Speaker terminal array was 3 pair plus center, is now 3 pair plus center AND dedicated posts for non-powered Zone 2 speakers in addition to ports for powered Zone 2 speakers (or Atmos)11. They are a really top quality product, comfortable in the ear with great sound quality Didnt want to go through the trouble of disassembling it and return so kept it. I was watching tv and taking my time. Just be prepared to have dirty hands and walls.
