The pegs themselves are the same diameter as Olympic bars so you would have to compress springs if you want to store your springs on the tree. They run small, I had to return them :( My daughter is originally a 9 1/2 & I got her a 9 because I went along with the chart. Belkin support is good, but the adapter is flawed. I got the same orange colour, or so I thought when I ordered them. all reviews ive seen say its great, on my copy i have some flex on the right side. A shame, my HD558 sennheiser cans are my favorite. I sweat so much more when I wear this. -Feels well made-Good seal around ears-Easy to adjust size-Awesome that it comes with a plug adapter for different uses. I even spent way more on the buds brand that start with a B and these outperform them. I had to do additional searching to find the 64-bit version.
