Verarbeitung und Qualität Top wie immer . Would def recommend! Only other issue is the bolts that show are now bronze M8 hex bolts, not black as pictured. Tenía grandes espectativas de estos audífonos, lamentablemente me decepcionaron y mucho, el sonido es muy bajo, tiene poco volumen, nada de potencia, no se aprecian los bajos, definitivamente no los recomiendo para nada Dont do that. Then what little charge it retains (maybe a half hour tops) is a big disappointment. But if you?re going to watch movies than expect a longer time before replacing it. We must have received a fault unit at first as we?ve had no issues with the 2nd unit. The antislip is amazing. I keep asking if it sounds OK and everyone says I sound fine.
