It?s a little wobbly, like barely, but it could be because where we have it setup is a little uneven. I purchased this to use with Jabra 85t earbuds. I love being wireless and I am very pleased with the sound quality. The bass is rich, the mids are pronounced and well defined, and the highs are great. Emailed Earbuddyz and the offered to send out a ?larger? set that may improve the fit. My son picked these out because he looooves dinosaurs and well. Piacevolezza di ascolto con ogni genere musicale ( le mie preferenze personali spaziano dal rock al jazzDalla lirica alla SinfonicaDal Rap al country ecc. Está fabricado en fibra de carbono, piel y acero, las almohadillas tienen un tacto nada sintético y los cosidos se notan de muy buena calidad. Sí funciona para ensayar la guitarra conectada a un amplificador que tenga salida para audífonos (el adaptador es bastante útil) tanto por el largo del cable como por el rango de frecuencias. I feel where I returned for this issue before it?s a continuing issue.
