These headphones can also be used for DJ work, thanks to the swiveling earcups that let you monitor audio while keeping one ear free.

Whether you're listening on a smartphone, an iPod, or a tablet, these headphones deliver detailed sound even in noisy environments. Over-Ear Design The over-ear design isolates sound in loud environments and prevents leakage for optimum listening conditions. This design is good for listening to music on a busy street, and for DJs who need to monitor their audio in a noisy club. DJ Applications The headphones are suitable for DJ applications and include a tuned bass response for low-end clarity. The pivoting earcups are ideal for one-ear or on-the-shoulder monitoring. A padded headband offers to keep you comfortable during a lengthy session. Broadcast and Podcast The headphones allow for monitoring audio on a laptop or in a home studio as well as recording a vlog on a smartphone. Swiveling and Rotating Earcups If you're a DJ who likes to keep one ear free, you can swivel one of the earcups for on-the-shoulder monitoring. The earcups also rotate 90 so you can turn one of the earcup outward for one-ear handheld monitoring. 10' Cable A headphone cable that's too short is almost like sitting on the sidelines?you can't be part of the action.
