The meh: The piece does not slot absolutely perfectly into the headsets indentation for it, thus making a small little gap. I simply cut it off and “sealed” the end with a lighter. It tilts front and back, though not side-to-side. I bought the wonderboom 1 in the June from Amazon for $80 for a family member and wished I got one for myself, then the wonderboom 2 came out and has stayed at $130. Maybe the straps have loosened or the added foam has compressed. I bought two pairs and ended up returning both, unfortunately. super au touché! If the adhesion stops I will edit the review. Love the design and good quality. Mi consejo es que si vas a usarla con una MTB piénsalo porque vas a tener que cambiar la llanta o comprarte unos tapones para los oídos
