Pressure-relieving urethane foam earpads fit comfortably and minimize ambient noise. The dual-folding compact design collapses easily into the included carrying pouch. The durable 4' flat cable has a serrated, tangle-reducing finish. The cable's in-line remote gives you volume and track controls for iOS products, while the built-in microphone makes it easy to take calls.
