Buy Headphones on EMI

Go for an easy EMI scheme which allows you to pay for your orders over a convenient period. A minimum purchase value of Rs. 500 is required to avail the EMI facility and the facility can be availed for tenures of 3, 6, 9 or 12 months.

After checking out, Select the "Credit Card / Debit Card / Net Banking / EMI" option, which will then direct you to the CashFree Payment gateway. Select your card and check the installment value and the overall interest charged on the transaction. 

The interest rate charged varies from bank to bank. Here is a summary of the interest rates:

Bank 3 Months 6 Months 9 Months 12 Months 18 Months 24 Months
AXIS 12% 12% 14% 14% 15% 15%
STANDARD CHARTERED 13% 13% 14% 14% - -
ICICI 13% 13% 13% 13% 15% 15%
YES BANK 12% 12% 13% 13% 14% 15%
HDFC 15% 15% 15% 15%

These are annualized interest rates charged on a monthly reducing balance, which means that the principal amount is reduced with every EMI and the interest is calculated on the outstanding balance.

No processing or convenience fees are charged on any EMI transactions.

PLEASE NOTE:

  1. Minimum Order value for EMI eligibility varies from Bank to bank. 
  2. EMI purchases need to be made on a single credit card and cannot be split across multiple cards.
  3. EMI monthly schedules begin from the next card billing statement post the transaction date as determined by your bank.
