the headphone be great but for the amount of money I pay the quality be poor . I would think that the quality of the diddy beat should be top of the line . I purchase the headphone for my girlfriend as a gift for we vacation trip . the sound and bass be excellent , just a perfect headphone . during we trip two day later the talkcontrol stop work , it be a pain because my girlfriend would not stop complain about the talkcontrol troblem . I finally call after we trip and amazon customer service be great , they make it fast and easy to replace the headphone . still today she love the headphone . great headphone and amazon make the process easy and enjoyable to order . aa -
