As mentioned before, these headphones provide a wireless connection to your smartphone or tablet via Bluetooth or NFC One Touch, which means: no more hassles with cords getting tangled or broken! If you prefer to use a cable, however, you can. These Sony headphones are lightweight and comfortable on the ears, thanks to the soft ear pads and adjustable headband. A nice addition is their built-in microphone, which make them possible to be used as a headset. Answering incoming calls - including via Skype - is simply a matter of pushing the button located on the right ear pad. Use the included USB cable for quick and easy charging.

Sound reproduction

These headphones deliver highly-detailed audio reproduction thanks to their 40mm drivers. Combined with a sensitivity of 90dB and a frequency range of 8 to 22,000 Hz, these headphones boast undistorted sound wherein all frequencies are audible at any volume level. Because they have a closed construction, ambient noise is effectively countered, and those in your environment won't hear what you're listening to either. Ambient noise can be disturbing when you're listening to music, an exciting movie, or anything else that demands your full attention.

Noise cancelling

Noise cancelling is a relatively new technique which reduces disturbing ambient noise by actually adding noise. An internal microphone analyses the sound waves coming in, then creates a wave of the same amplitude but with an inverted phase, which turns positive sound waves into negative ones, effectively cancelling each other out. These inaudible frequencies are then transmitted through the headphones' drivers. This ideal feature for noisy environments like busy offices, airplanes, or in the train isn't necessarily exclusive for listening to music, however. By activating the noise cancelling function on these Sony MDRZX770BNB headphones, you can experience a completely sound-free environment; a great benefit for people suffering from hearing problems like tinnitus or hyperacusis.
