Si no cuentas con los espacios para atornillar el porta agua debe comprar el adaptador y el porta botella. The headset isnt the greatest at noise cancelling which for me is a bonus, I can still hear if someone needs me or wants my attention. Plus no sudden caffeine drop and amino acids?

Fonctionne très bien après une installation plutôt facile. Stores my headset
