The Volkano Rhapsody Series Active Noise Cancelling Bluetooth Wireless Headphones (model VK-2006-BK) are designed to provide a high-quality audio experience with the added benefit of active noise cancellation. These headphones offer both wireless Bluetooth connectivity and a wired Aux input option, making them versatile for various listening scenarios.
Function Description:
The primary function of these headphones is to deliver audio wirelessly via Bluetooth 5.0, allowing users to listen to music, podcasts, and other audio content from compatible devices. The active noise cancelling (ANC) feature, with a 25 dB noise reduction, helps to minimize ambient noise, providing a more immersive listening experience. The headphones also support hands-free calling through a built-in microphone, enabling users to answer and make calls when paired with a smartphone.
