I recently bought Boat Rockerz 400 Headphones from Amazon India during the sale at INR 999. I am surprised by the bass it has, it is just amazing. It’s a value for money product. Also the battery backup is quiet impressive, with normal usage of around 1 hour a day the battery lasts me for a week, with 2 hours of charge I can use the headphones easily for a week. The only thing I didn’t liked about them is the mic, don’t get me wrong it is not bad but compared to wired microphones it has less sound reception. Overall I can conclude it as a very nice product. A note for those thinking to buy these headphones they are available in different color but don’t go for the black color ones as the material used in padding of those headphones gets worn out easily, so plz consider this while buying it. Happy Buying!
