Sony Wireless Noise Cancelling Stereo Headset Black BZ [Refurbished] WH-XB910N (B) WH-XB910N

Two sensors (microphones) positioned on the outside and inside of the headphones collect ambient noise, and both the noise and the music signal from the player are digitized. The DNC (Digital Noise Cancelling) software engine integrates two methods, feedforward and feedback, to precisely generate out-of-phase sound that cancels out noise. You can fully immerse yourself in the deep bass you desire without worrying about noise. By boosting the deep bass frequencies with the built-in amplifier, these headphones reproduce powerful bass sounds. Furthermore, the structure that enhances airtightness from the driver unit to the eardrum, and the duct located on the housing, optimize the movement of the low-frequency diaphragm. This achieves a balance between overwhelmingly powerful deep bass reproduced with precise rhythm and clear treble, delivering impact and realism directly to your ears. High-precision voice pickup technology: High-precision voice pickup technology achieves superior call quality by optimally controlling two microphones—a feedforward microphone on the left housing and a dedicated microphone for calls—and performing advanced audio signal processing. Your voice will be transmitted clearly even in noisy environments. The touch sensor control panel on the housing allows you to control music playback on your smartphone or other device, including skipping tracks, rewinding, playing/pausing, adjusting the volume, and even answering/ending phone calls. It also supports activating smartphone voice assistant functions such as Siri® (*1) and Google™ app (*2) (*3). You can perform a variety of operations using only the headphones without having to take out your smartphone. You can see the current status of your headphones at a glance, including the remaining battery level, the connected codec, and whether DSEE is ON or OFF. Experience powerful, deep bass with high-performance noise cancellation.
