I have bought boat rockerz 400 a month ago from Amazon India for rupees 1300. It was during Amazon great Indian sale. The packaging was really impressive and the product seems very well built. My headset was black in colour. Whenever I started to listen music I was really disappointed there was extraordinary Bass but the sound quality was very poor. I can’t hear vocals of the singer in any song I have heard. This headset is totally uncomfortable on on my ears. I feel pain ful if I use this headset for above 15 minutes. The bass produced by the headset is really overpowered sometimes it feels very stressful to my ears. The only advantage of using this headset is is that it is having a Bluetooth connectivity it seems working fine but occasionally some chopiness can be heard if my phone is about 5 metres away. The battery life of my headset is pretty average and it last about 4 hours of music play.
