Call us sound snobs, but we think that if you want genuine ANC, the premium segment is your only choice, as most headphones below Rs 20,000 are ineffective at blocking external sound. In India,, you are likely to have two choices in the premium ANC zone - the Sony WH-1000XM series or the Bose Quiet Comfort (QC) series. The Bose QC45 was launched lastyear at Rs 32,900. At that price, they were impressive. At Rs 19,000 now on Amazon, they are awesome!
