My bluetooth speaker that i just bought makes a vibrating zzz noise along with the bass noises. I was wondering if this was normal? The mids and highs sound good its just the bass. Everything sounds good when song has not much bass. I am suspecting it is a defect as i dont beleive the audio can be that bad( considering the price i paid and the fact that the mid and highs sound so good) Its not necessarily the bass that sounds bad, but some distorted noise comes with it. It is really obvious when i am playing the song 'betrayed' by lil xan in the beginning and happens in other songs and films.
