Can't believe how much details I am missing out with other gaming headphones and even my daily driver earbud. Everything sounds so intense yet clear now!

Sheryl Lee | Singapore | Switch, PC

Used to get terrible headaches from ear fatigue, these seem to have solved that. Bringing it to work for meetings and casual gaming everyday!

Aiyln Toh | Singapore | Switch, Mobile, PC

High quality sound for gaming and music, even comparing it to my other high-end earpieces which was already crystal clear... or so I thought.

Howard Tan | Singapore | Playstation, PC

Love how good they sound in a game like Dark Souls 3 where sound design plays such a big role in setting the tone and ambience of the experience.

Mister Young | Power 98FM | Playstation, PC

Now I can game longer without ear fatigue, but the 3D audio is so intensely good that I can't last more than 10 minutes in horror games.

Wireless For Audiophiles

Greater transfer rates preserve more data. The simpler aptX codec supports 48kHz/16-bit LCPM audio data (352kbps), while aptX HD on the Vulcan BT supports 48kHz/24-bit LCPM audio data (576kbps). Some might call us excessive, but no mainstream solution even comes close.
