Earlier I bought a lower model of Samsung buds Core that was awesome, I thought FE is a higher that core so I bought it from Carrefour Application but just after use it I found its sound quality is good, noise Cancellation is good but the main issue is its Mic which is poor quality also the ear fitting is not comfortable you can't keep it in your ear I just remove after use. When I was trying to return it Carrefour is not allowed to return it. So I suggest you if you want to buy this type of product avoide Carrefour, buy from other app like Amazone or Noon etc so they will allow you to easy return.
