Jai retourné le premier casque croyant à un autre problème mais le résultat est le même avec le 2e. Esto aunado a que si ya posees los HD598, es difícil percibir una diferencia en el balance tonal entre estos dos pares. Will definitely order again. They are water resistant and say they can be used to workout. They fit great, are durable, and as far as I can tell, theyre actual Crocs. I can recommend the Mojo to have great synergy with this headphone. you can tell they are well made and dont tangle like normal headphones! these. Pairing was effortless. Theyll probably sit in my junk drawer for the rest of their days, should have listened to my son and put my money towards a proper pair.
