As its name is boss heads, I think it outputs good boss. I studied many reviews and finally bought this. But disappointingly I didn’t satisfy this product. Ear buds are little hard. Bass is like normal earphones. nothing special in this. Sound also coming low. This is not working at all in Moto G4 Plus. In remaining phones, it is working. I purchased it for 499 INR in a deal. But compared to the price it is not valuable. Its quality can get from any local market earphones worth 100 rupees. And there is no service center near to my location to check it. Earphones are not plastic. They are metal earphones. So they feel the little weight to our ears. after using more than half an hour we felt inconvenient. many times they are slipping down from ears. So I never suggest this earphones. better to try Skullcandy or JBL or some other.
