Best headset for listening to music and taking calls
By Himanshu Singhon
I am writing this review, feeling a bit disappointed. That is because I purchased it for 5490 from reliance digital. I did not check the online prices which are almost 10% (here, 20% and 25% on Amazon and snapdeal respectively) less than the price I paid for. But I wanted to actually try out a headset which is ideal for both listening to music as well as take calls.
Now, having tried this for both, I am really happy with the headset. The sound quality is amazing and having tried a few other headsets at this price range, I can confidently say that nothing else comes close. Even at high volumes (and I prefer very high volume for my music) the clarity is amazing. By detaching the Bluetooth from ear buds, Sony ensures two things: the speaker can be place closer to your mouth but at the same time there is no weight on your ears. I primarily use them for taking calls while driving, and even if there is no call for over an hour, I don't feel a thing. plus as against 'over the ears' headphones these are far more comfortable to wear and are very compact to carry in your pocket along with your phone itself. All in all, I have only good things to report on this product (wish I had purchased it online though :( )
