I would actually rate it a 4.5 it's really good wireless earbuds really good value the only thing that can prove it is probably the app if they update it so they supported go air pops
Sound is like an old AM radio. Very high-pitched. No bass. I tried all 3 settings and hardly noticed a change. I tried every adjustment imaginable in my phone's equalizer settings and still not close to happy. Lowering the highs, or trembles, lowered the overall volume. My only experience is comparing the sound to the free corded ones I got from the airplane. I was more than satisfied with the sound from the free ones. Sound from my JLabs Go Air Pop isn't remotely close.
The first one was faulty, but the second one wonderful. It works perfectly. And the warranty process was great. The next time I need ear buds I’ll buy from you.
