ASUS ROG Kithara A702

The ASUS ROG Kithara A702 brings a 100mm planar magnetic driver and a shockingly good boom mic, landing in the top tier of our sound and microphone tests. It's wired-only and open-back, so isolation is nonexistent and comfort suffers under the 422g weight. But for under $400, the audio fidelity competes with setups costing much more, making it a stellar value for a stationary desktop rig.

ASUS teamed up with HIFIMAN to create something a little unusual: the ROG Kithara A702. It's an open-back, over-ear headset built around a massive 100mm planar magnetic driver, with a detachable boom mic that's suspiciously good. This isn't your typical gaming headset, and it definitely isn't a wireless travel companion. It's aimed squarely at people who want audiophile-grade detail at their desk, whether they're mixing tracks, diving into lossless music, or yelling at teammates in between rounds. The specs tell the story right away: 8Hz to 55kHz frequency response, 16 ohms impedance, and a whole bag of included cables. For $300 to $370, you're getting desktop audio that punches way above its price.

The open-back design is a declaration, not a compromise. It means you get a vast, airy soundstage that closed-back cans can't match, but you also get zero isolation from the world around you. The 422g weight and metal frame feel premium, but they also land this headphone in the bottom of our comfort rankings. This is a product for a quiet room, a good DAC, and someone who values sound above all else. Think of it as a personal listening station, not a grab-and-go accessory.

What makes the Kithara interesting isn't just the driver size, it's that ASUS actually tuned the planar magnetics with enough care that it competes against dedicated $500+ HIFIMAN or Audeze headphones. Then they strapped a studio-quality microphone on the cable and threw in both balanced and single-ended connectivity. The result is a strange, wonderful mutt that excels where most gaming headsets fail, and fails where most people spend their money: battery life, ANC, and portability.

Our sound analysis puts this headphone in the absolute top tier of everything we've tested. The 100mm planar driver reproduces sub-bass all the way down to 8Hz with zero audible distortion, so you feel the rumble in orchestral swells or cinematic explosions without any mud. Mids are natural and uncolored, letting vocals and acoustic instruments sit right where they should, and the treble extends cleanly past what most ears can hear. The open-back architecture gives everything space to breathe; imaging is precise, and instrument separation is a genuine standout. It's the kind of presentation that makes you rediscover your favorite recordings.

The on-cable MEMS boom mic is another high point. With a full 20Hz to 20kHz response and impressive signal-to-noise ratio, it captures voice with a clarity that borders on podcast-ready. In our database, the mic performance lands near the very top of the charts, meaning your voice will sound richer and more lifelike than through any traditional gaming headset mic. Whether you're on Discord, recording voiceovers, or streaming, it's easily among the best boom mics we've seen bundled with a headphone. The analog cable controls are straightforward and get the job done without any software fuss.

At $300 to $370, the Kithara is an absurdly good deal for the sound you're getting. A standalone planar magnetic headphone from HIFIMAN or Audeze with this level of performance often costs north of $500, and you'd still need to buy a separate microphone for gaming or calls. Here, you're getting the headphone, a detachable boom mic that's genuinely great, two sets of earpads, and a cable kit that covers everything from professional balanced outputs to your phone's USB-C port. For a desk-bound setup centered on critical listening, music production, or competitive gaming, the price-to-performance ratio is hard to beat.

Compared to the wireless ANC crowd that sits in the same price bracket (Sony WH-1000XM6, Sennheiser Momentum 4), the Kithara sacrifices every travel convenience in favor of pure sonic fidelity. But if you already have a quiet space and a good source, the money goes into driver quality and build instead of batteries and noise-cancelling algorithms. That makes it a specialist's purchase, but one that doesn't overcharge for its specialization.

The most obvious alternatives are the Sony WH-1000XM6, Sennheiser Momentum 4, and Bose QuietComfort Ultra. All three offer wireless connectivity, excellent active noise cancelling, and all-day comfort for a similar price. If you need a headphone for commuting, travel, or open offices, any of those will serve you far better. But they can't touch the Kithara's soundstage width, bass extension, or overall detail. You're trading the convenience of Bluetooth and ANC for a wired, open-back experience that's simply in a different league sonically. For mixed use, the Sony or Sennheiser make more sense; for a dedicated listening station, the Kithara is the clear winner.

Stacked against dedicated audiophile open-backs like the HIFIMAN Sundara or Edition XS, the Kithara holds its own while adding a killer mic and versatile cabling. The Sundara is lighter and more comfortable for long sessions, but it lacks the integrated microphone and the balanced accessory set. If your setup splits time between music production, critical listening, and voice chat, the Kithara eliminates the need for two separate devices. Just keep in mind it's not meant to leave your desk, most competing planars aren't either, but the added weight makes the Kithara less forgiving for marathon listening.

If you need a headphone that works on a plane, in a busy office, or even on a quick coffee run, the Kithara is not for you. Its open-back design leaks sound badly and offers no isolation, and there's no ANC to dull the roar of the outside world. The weight and comfort issues also mean long sessions can get tiring. For a portable all-rounder, the Sennheiser Momentum 4 or Sony WH-1000XM6 deliver wireless freedom, excellent noise cancelling, and all-day wearability at a similar price. You'll trade some audio purity, but the real-world usability is night and day.

Also skip this if you're looking for a bass-heavy, fun tuning. The Kithara goes for accuracy and extension, not boosted sub-bass that rattles your skull. If you crave thumpy, exaggerated low end for EDM or hip-hop, a closed-back dynamic headphone might be a better match.

For the person with a quiet room, a decent DAC, and a craving for audio detail, the ROG Kithara A702 is an easy recommendation. The sound quality is among the best we've tested, the microphone is a standout, and the whole package feels premium. It nails the use case it's designed for: stationary, critical listening coupled with high-quality voice communication. If that's your entire workflow, you'll be thrilled, and you'll spend less than you would piecing together a rival setup from separate components.

If your life involves even occasional on-the-go listening, or if you share your space with other people, this isn't the headphone for you. The open-back design means everyone hears your music, and the lack of ANC means you hear every conversation around you. Factor in the 422g weight that ranks near the bottom of our comfort tests, and it's clear the Kithara is a homebody. But for its niche, it's an incredible value and a genuine standout in a market full of wireless compromises.
