These are the only brand of headphones I will buy. The sound quality is amazing and I love that the block out all other noise. I can put them in and not have to hear anything going on around me. Plus, they are super affordable! Sound Quality Really great sound quality, especially compared to other cheaper earbuds. Music sounds deep and has non of that tinny quality that I find with most earbuds. Comfort These come with 3 different sizes of attachments for different ear sizes, which is awesome. I have to use the smallest size, which is very comfortable, but I couldn't keep these in all day. Design The cord is a bit on the stiff side, so I find when using for exercise it can make a lot of noise in my ears, but otherwise I love how these look and work. Durability They last quite awhile, the only reason I have bought new ones is because I tend to lose them. But even when I do have to re-buy, its not so bad since they are very reasonably priced for such amazing sound quality!
