Not rattling or buzzing. These earbuds sound wonderful. Very Pleased. Delighted with these earbuds, they are so comfortable to wear, even for hours on end; I almost forgot I had them in. Use to have a pair when was in uni but sadly fell apart after a couple of years and these have been the best so far . Also, I wear a 10 in boots and 9. Summary:Overall, these are good. Also too short for my liking and it rides up even more so Id constantly be pulling this dress down all night. I love them I will recommend I rate these headphones highly for their value, almost $100 less than the Apple buds they imitate, and which I also have.
