You can easily switch between music and phone calls with the Sony MDR-ZX110NA. You answer a call with the remote control in the cable and call hands-free with the built-in microphone. Listening to music in noisy areas like a train station or an airport? Thanks to noise canceling, the headphones muffle the disruptive ambient noise somewhat.
Note: the noise canceling of these headphones only partly muffles the ambient noise.
