The first time I tried it took me a few seconds to get into it. But after a few days, it became my favorite music player to take to the gym or for running. Definitely, the best sports digital music player I’ve tested so far.
El problema con alternativas como el iPod Shuffle o el Nano es que, dado a que son reproductores independientes de los audÃfonos, el lidiar con el cable, cuando estamos corriendo, levantando pesas, o en la bicicleta, es un verdadero problema. The problem with alternatives such as the iPod Shuffle or Nano is that since they are independent from the players headphones, dealing with the cable deal when running, lifting weights, or on a bicycle, is a real problem.
The headphones remained firm in my ears no matter the level of exercise, either running quickly, jogging, or on a bike, never felt a discomfort with the headphones. Perhaps it is because the technology is advanced enough that a player can exist on the headset and not only weighs less but feels comfortable.
