I have bought boat rockerz 450 headphone before 6 months. Its performance, audio quality , battery backup , everything is fine but it’s padding is not comfortable in ears.Using more than 2 hours continuously it causes pain in ears . Because of this I stopped using that headphone.I have bought the masaba edition but in my review it is overall good but only it’s padding is not good for ears. It is not comfortable whereas boult thunder headphones are more comfortable than boat rockerz 450 .
