When it comes to portable speakers, it is evident that there is a trade-off between price and quality of sound which is unfortunate. The Sony SRS-XB13 is a new portable Bluetooth speaker that claims it has the best of both worlds. At ₹3990, it is a bargain for a speaker that is part of the EXTRA BASS family of Sony. It has a diffusion processor that expands sound in any space, however, since it has a single driver, the sound is in Mono only. For stereo sound, you can link two speakers which makes the sound even bigger. The 16-hour battery life and IP67 make it robust and resilient to the elements. It is available across Sony retail stores, major electronic stores, Amazon and Flipkart.
