I love the Marshmallow earbuds.
I have to keep some background noise playing 24/7 so I listen to a lot of music and stuff. The bad news is I have to by new earbuds every few months, 12-18 hours of use 7 days a week. The good news is I get a chance/reason to test out different products. I know nothing about audio, but Ive used many of the different earbuds out there. Marshmallow earbuds are, to me, the best thing for the price.
The sound is great, and the foam earbuds are very comfortable and act just like earplugs. They are great for cancelling outside noise. I sometimes where mine 12hrs+ at a time. So yes VERY comfy.
Ive only found them at walmart =[ about 20$ usd.
