Buy anker. Sonido: es cierto que estos auriculares (al igual que otros equipos Marshall como su altavoz activo ACTON) colorean el sonido; es decir, según indica el propio fabricante en la caja, resaltan ligeramente graves y agudos. I ordered a 6 and they were far too big. Smaller than i expected but worked for what i wanted. Had to order a size smaller than he wear in tennis shoes but they fit perfect! I don’t have a problem with the right but I don’t want to be a able to enjoy only one ear bud. Sadly, even though I dont feel those terrible drivers anymore, the headset is even more tight on my head. But I wanted a second bar for hand towels and so re-ordered what Id received several months ago. Es ist an sich nicht stark, aber wenn ich mir mal wieder ein Headset kaufen sollte, weiß ich worauf ich achten muss. I was getting low on my REAL Gucci Guilty perfume and decided Id give this a try so Id have a backup once mine was gone.
