crackling sound

Bought it just 3-4 days ago. First day of use is fine but it started to make crackling noises in the later use.

Tried the "pair and unpair, hold the middle for 5 sec and press twice until the red light " method, not fixing my issue.

I own a pair of x3 and it lasted for almost 3 years. It also started to crackle recently might be because it is old, so I decided to buy tarah pro. I loved my x3 but it is very disappointing to see this issue on a new pair of $100+ headphone. :< 

Can someone help please.
