it's one of best Bluetooth speakers around, if you compare this with JBL flip 4, I would recommend you go for Sony SRS XB21 because the amount of bass and vocal clarity the JBL doesn't have and many people also reviewed this product is awesome and battery life could have been better!

Sony has always done their best in building up thier gadgets. SRS XB 21 is a good speaker but when you go for the base the customised bass especially the sound quality deteriorate and give a torn bass. I have bought an older versions like SRS XB 20 and SRS XB 40 the customised base of this older versions of speakers have always resulted a deep increased bass. So if you are a great best lover then go for the older versions such as SRS XB 20 40 30.

best speaker for listning metal and hiphop

nice speaker but battery backup is less ,overall nice speaker

Xcellent product

I got this product for 4.5k during offer period. I personally feel that i couldn't get expect anything else from this amazing speaker at this price. Sound quality is crystal clear and bass is awesome. The only aspect in which it lacks is its stand ( and battery upto some extent). The speaker needs a firm base for a perfect output. Battery may not meet expectations for a past JBL speaker user.
My final verdict would be if anyone is looking for a speaker around 5k srs xb21 will be my choice an...

Everything is good but bass.
Battery backup is average.
Wish the bass was more punchier.

Everything is perfect but battery backup is really very poor. As per company's specifications battery last longer for 12 hours or 8 hours but honestly it can be last for only 4-5 hours only.

nice product for budget when compared to jbl flip 4,full water proof and extra bass but battery backup is not satisfied.... 👍

slightly costly but a good product
