Do the headphones provide noise cancellation without audio playing?
Yes, the noise cancellation function works when the headphones are powered on, even if no audio is actively playing.
Do these headphones support Dolby Atmos?
No, the WH-CH720NB model does not feature Dolby Atmos support.
Are the headphones foldable and is there a carrying case included?
No, these headphones are not foldable for compact storage. A carrying case is not included with the product, and Sony does not list an official case designed specifically for this model.
Can I use these headphones with my television?
Yes, they can be used with televisions that support Bluetooth A2DP profile for wireless audio. Alternatively, you can use the supplied 3.5mm audio cable for a wired connection to the TV's headphone jack or compatible audio output.
Do the headphones require a constant connection to work?
To output audio, they need to be connected to a source device either wirelessly via Bluetooth or wired via the audio cable. The noise cancellation function, however, remains active when powered on until manually switched off via the button or app, regardless of an audio connection.
Is there significant sound leakage from these headphones?
As with most over-ear headphones, some sound leakage may occur at higher volumes, though the closed-back design helps minimise this.
What is included in the box with the headphones?
The package typically includes the WH-CH720NB headphones, a USB-C charging cable, and a 3.5mm audio cable for wired connection. Documentation such as a user guide and warranty information is also provided.
