These are excellent and for only $20?!?! I wear them at work where it was measured at 90 decibels loud and they muffle the sound really well. I am very happy with them and they sound great, look great (got the red ones) and overall a great product!!! Thanks Jlab
The sound quality is quite poor. There is a substantial dip in the lower midrange and also a lack of bass which leads to thin and tiny sound. Sadly, this can't be fixed with any of the 3 different EQ modes.
