Refurbished Sony Wireless Stereo Headset Blue LZ Noise-Canceling WH-XB910N (L)

【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. Noise signals picked up by two sensors (microphones) located on the outside and inside of the headphones are all digitized, along with the player's music signal. The DNC (Digital Noise Cancelling) software engine combines feedforward and feedback techniques to generate highly accurate anti-phase sound that effectively cancels out noise. You can fully immerse yourself in the deep bass without worrying about noise. The built-in amplifier boosts the deep bass range to reproduce powerful bass sound. Furthermore, the structure has been made more airtight from the driver unit to the eardrum, and a duct has been installed on the housing to optimize the operation of the low-frequency diaphragm. The headphones deliver both overwhelmingly powerful deep bass and clear high frequencies, reproduced with precise rhythm, delivering a powerful and realistic sound directly to your ears. High-Precision Voice Pickup Technology: High-precision voice pickup technology optimally controls two microphones, a feedforward microphone in the left housing and a dedicated microphone for calls, and performs advanced audio signal processing to deliver high-quality call sound. Your voice is clearly heard even in noisy environments. The touch sensor control panel on the housing allows you to skip forward/backward, play/pause, adjust the volume, and even answer/end calls on your smartphone or other music player. It also supports activating your smartphone's voice assistant functions, such as Siri® (*1) and the Google™ app (*2). You can perform a variety of operations using just the headphones, without having to take out your smartphone. You can check the current status of your headphones at a glance, including remaining battery life, the connected codec, and whether DSEE is on or off. High-performance noise cancellation delivers powerful bass.
