OK now I will give you a detailed review of Boat Rockers 400. I am reviewing after 10days I got the product.
* Light weight. It is similar to carrying a 100 pages notebook
* Sound Quality at the best level especially Bass is simply superb.
*Noise cancelation is at the top.. I travel by local train often.. I sat near the Window seat and used this headphones one day, I was totally amazed at its noise cancelation. I am unable to hear a little bit of sound of the Running Train.
*Dual working mode. This is simply superb, even battery is dead u can listen to music
* Best battery.. I charged for less than 2hrs and used it about a week.
*Cheap when compared to other brands. No brand offers Wireless headphone at this rate. Most of brand doesn't offer dual working mode too.
*Boat offers one year warranty for this product. Any defects BOAT collects the product from door step and repair it and return it to the door step.
*Only I problem with this is that it's not durable. But it's natural that if the headphones is of light weight then it won't be durable but it is better to increase the weight rather than being less durable.
* Since it's less durable you have to carry it with any POUCH else on Neck,. If you keep in bag there are more chances that it may break.
*Wired mode and Bluetooth mode doesn't have same quality for all songs. Don't know whether it's song's mistake or Rockers 400 ''s mistake.
*It's very small, at the initial stage I felt pain on ears if I use it more than 15 minutes.. Later I didn't feel such pain..
Now my personal opinion is, if you are looking for a good headphones at cheap rate go for it.. Wait for any special offers. I got it on INDEPENDENCE DAY SALE @ 999 INR I also got 50rs as AMAZON PAY cashback.. So effective price is 950 INR. Wait for a best deal
