bass is great i would give it 5 out of 5 for bass and its pretty loud with some smartphones like realme or mi and not very loud with phone like oneplus 7t but sometimes there is distortion when its bluetooth is on and its battery i dont know why it goes from 90 to 70 percent and straight away from 70 percent to 30 percent and when it reaches 30 percent battery it beeps continuously after every 15 to 30 seconds when you listen music via aux there isnt much bass thats what i didnt like o
