The Extra Bass series from Sony just got its new dollop of head smashing bass and can give your ears a proper workout. These headphones offer all the much-loved features from the previous Extra Bass headphones, while adding multiple key improvements including refined vocal clarity for an overall better audio experience. The XB700 comes with a whopping 30 hour battery life and supports quick charge via USB Type - C. But that’s not all. You can fully customise the output via Sony’s app, just like the higher end NC models and it also supports voice assistants should you need one. And if for some reason you can’t stream via the aptX Bluetooth, Sony’s thrown in a 3.5mm connection as well for passive operation. All that for just Rs. 8990, but it will be available on sale only on the 15th through every major retail outlet.
