This is crucial in competitive gaming. Liked being able to lock the carrier to the rack, and the dual position of the unit. Edit: Just over a year after purchase, I experienced problems with the headphone speakers detaching from the headset. Lindos y cómodos EN CONCLUSIÓN: para el precio que tienen (poco más de 17 EUR pagué yo), te llevas unas chanclas de gran calidad que no puedo más que recomendar en base a mi experiencia. These are not going to impress people who want nothing but stanky bass, but for those of us who want GOOD SOUND OVERALL, the ZS10s deliver. What more could you want? Overall, happy with the purchase. I arrive much fresher. I typed this whole review out on the board and only made 1-2 typos.
