Hi @Aravindhan_Vadivel1, sorry to hear your having issues with your SoundCore 2. Couple of questions;
- does the buzzing occur when no music is played?
- does it occur when playing via aux connection?
- have you tried unpairing and pairing your BT device again and/or tried another BT device?
If you’ve tried the above already and the issue is still present I would reach out to email@example.com with your serial number, purchase date and location for a warranty support claim.
