### ⭐⭐⭐⭐ Review
*by A***A on 8 July 2025*

Why did you pick this product vs others?: Nice TWS earphones under ₹1000 . Nice audio, good battery life. However after 1 year of use there was some trouble in charging one of the earbuds in the case. I used to adjust using a piece of paper to make it sit in a position where it continued to charge. Also the case is not waterproof it is not working since I got drenched in rain with it in my pocket. So, decent product needs to be handled carefully.
