Dear @Daksha_R_Nair
Since your Nirvana Crystal Black headset’s right side stopped working within 4 months of purchase and is under a 1-year warranty, you’re eligible for a replacement. Please visit https://support.boat-lifestyle.com and submit a new service request with your invoice and clearly mention the earlier confusion. If the issue isn’t resolved, escalate to their support team with your ticket and invoice details.
If still need help, reply to us.
