I downloaded voice meter banana to use as and equalizer and the app also has a gate(which blocks background noises) these two products together sound great. although I have to give a 4 star only because I was a little shocked at how the shoe discolored under my foot. This is very strong and well made. I got this for my teenage son and he loves it! The sound is excellent, really rich clean bass . The hole the stem goes in doesn?t fit. When his birthday came around, I was just about to order the JBL Charge but then saw the BOOM 2. There is no skipping, lagging, or other errant behavior?it just points where I intend it to go immediately. They fit at first but seemed to stretch out and now keep falling off as I walk. Only issue I ran into was the size, it runs a bit large.
