Like its fellow Swedish brand QPAD QH-90, the bundle is completely filled with an accessory more than it (the airplane adapter). The big plus of this in relation to its competitors headphones are that it is a quality / price unparalleled extent. Its competitors have a price often much higher from 60 to 90 euros, they have them certent of 7.1, but you should know that it is only a spatial (7.1 fake poo all what) and that often the bass is too present which spoils the sound.
Often competitors helmets have a medium quality microphone while this one is very good, huge more on this one.
To top it all, the headset features a braided cable which is really great to compare QPAD who has only rubber cable.
