Asus launches ROG Kithara open-back gaming headset with 100mm planar drivers and HIFIMAN tuning
Asus is stepping a little outside its usual gaming headset formula with the new ROG Kithara. Instead of focusing on RGB lighting or wireless features, this one leans heavily into sound quality, and it does so with help from HIFIMAN, a brand better known in audiophile circles than esports arenas.

The Kithara is an open-back headset built around large 100mm planar magnetic drivers. That alone makes it unusual in the gaming space, where dynamic drivers are far more common. At $299, the Kithara is clearly aimed at enthusiasts rather than casual players.
The headset uses a fully open-back design, which helps create a wider, more natural soundstage. That can be useful for competitive games where spatial awareness matters, but it also means there’s no isolation.
Asus claims a frequency response of 8Hz to 55kHz, which is wider than human hearing, but the real takeaway is likely the tuning. It’s expected to offer a fairly balanced sound signature with good separation between bass, mids, and treble. In theory, that should make footsteps and directional cues easier to pick out without muddying everything with exaggerated low-end.

Unlike many gaming headsets, the Kithara includes a 4.4mm balanced connector, alongside standard 3.5mm and 6.3mm options, plus a USB-C adapter. The detachable boom mic uses MEMS technology and covers a typical 20Hz to 20kHz range.
The frame uses metal in key areas, including hinges and headband supports, and extra earpads are included in the box. At around 420 grams, it’s not lightweight. That’s often the trade-off with planar designs. Whether it feels comfortable over longer sessions will depend on head shape and tolerance for weight.
Reportedly, there’s no wireless mode, no active noise cancellation, and no flashy lighting. That may disappoint some ROG fans, but it seems intentional. Asus seems to be prioritizing sound over features this time.
A Different Direction for ROG
The ROG Kithara feels less like a traditional gaming headset and more like a crossover product. It’s positioned somewhere between an audiophile headphone and a competitive gaming too
