La calidad del sonido es buena, sobre todo los bajos, para el tema de medios y agudos también, lo que se puede disfrutar de un buen sonido para el precio de los mismos que es muy accesible. Auf der Quittung steht jedoch "Seagate ST2000DMZ08 BarraCuda 2 TB". We have these to him as a Christmas present and he loved them; he didn’t even know something like this existed. Now it looks complete! User manual some what hard to understand but seem to be great headphones. And sadly, there is no return option. It just makes for a better experience without issues. The quality is there and i recommend getting one size smaller then what your normal shoe size is Im normally a 13 and I got a 12 and they fit perfectly. These have been the best shoes for me while teaching not only ZUMBA, but every class I teach. It does one thing only but does it really well.
