I love how you can change the attenuators to different situations. I took them to Lost Lands with me and I went everywhere from up front to the rail where the bass was literally shaking my body, to the back to just chill and take a breather. I took them out during both situations, and boy was the music loud from up close or from a distance. In functionality, they work great! They were pretty comfortable as well. My only issue is that the earbud itself had already been tearing, I’m guessing from the continuous use of me putting them in and out throughout the entire time I was there. I’ve only used these for 1 camping dubstep festival so far keep in mind. Luckily, they come with 2 pairs black and white in all 3 sizes so I wasn’t that much upset. I took them to the club with me last week. My only suggestion to these guys is that they should sell replacement earbuds.
