Don?t waste your money, replay the second one and you will feel a lot better about your decision. I really hate writing "bad" reviews but this product unfortunately did not meet my expectations. I will reorder. The result is a fatigue-free sound quality that you can listen to for an extended period of time. Personally I love this style of gydration vest with the full fabric sections around the sides as I find them much more comfortable compared to those with straps. Ive only put 100+ miles on it and it has held fast in the silicone webbing. Hermosaaa You can adjust the equalizer, but the former statement holds true regardless. Love it for my dance studio. I ended up getting a slightly used pair on Amazon so I dont want to return them as defective and have to purchase new ones at the full price and have it be the same problem with the new ones at the higher price.
