If you want a pure wired planar-magnetic listening tool with a bass-forward, smooth-tuning character and pad-rolling flexibility for movies, choose Dekoni Audio Blue; if you need an open-back, wide-soundstage headset with an on-cable boom mic and broad plug compatibility for movies and gaming, choose ASUS ROG Kithara Gaming/Audiophile. Both are wired planar headphones, and neither is a wireless or Bluetooth design, so this is a comparison for listeners who care about the driver, the tuning and the cable rather than battery life and app features.
• Dekoni Audio Blue — biggest strength: a Fostex-sanctioned T50RP MK3 variant with 50 mm planar drivers, a semi-open cup, and two sets of ear pads in the box, so you can tune comfort and tone yourself.
• Dekoni Audio Blue — biggest trade-off: it ships with a 3 m cable and a 6.35 mm plug only, so phone and laptop use needs an adapter, and there is no microphone at all.
• ASUS ROG Kithara — biggest strength: ROG-tuned HIFIMAN 100 mm planar drivers in an open-back frame, an on-cable full-band MEMS boom mic, and a plug kit covering 3.5 mm, 6.3 mm, 4.4 mm balanced and USB-C.
• ASUS ROG Kithara — biggest trade-off: open-back headphones leak sound both ways, so they are a poor fit for shared rooms or noisy commutes, and nothing here is wireless.
• Who each pick is for: Dekoni Audio Blue for the audiophile who wants a warm, easy-going planar to listen to music and films in a quiet room; ASUS ROG Kithara for the gamer or movie watcher who wants one cable, one mic and one headset for PC, console and mobile.
Dekoni Audio Blue is a modified Fostex T50RP MK3 — the company describes it as the only Fostex-sanctioned mod of that headphone, built in partnership with Fostex itself. That matters if you already know the T50RP family and want a version that has been reworked rather than simply re-badged. The changes are specific: redesigned blue ear cups, a new inner baffle, and Dekoni's own hybrid ear pads fitted as standard. Dekoni is an American ear pad manufacturer based in New Jersey, so the pad work is the point of the project, not an afterthought.
The sound character is deliberately friendly rather than clinical. The driver is a 50 ohm planar magnetic unit with a 20 Hz – 20,000 Hz range, and the tuning is described as fun, with strong bass extension and a smooth top end. The fenestrated sheepskin on the inner face of the pads is there to bring back some of the midrange that the stock T50RP MK3 tends to lose, which is exactly the kind of detail that separates a thoughtful mod from a colour swap. The semi-open enclosure gives the driver room to breathe, so you get some of the openness of an open-back design without quite the same level of leakage.
Who should skip it? Anyone who needs a microphone for calls or co-op chat — there is no mic here. Anyone who wants to plug straight into a phone without an adapter. And anyone expecting a wireless or noise-cancelling experience: noise control is listed as none, and the connection is wired only. If your listening happens on a commute or in a noisy shared space, the semi-open cups will not isolate you.
ASUS ROG Kithara Gaming/Audiophile: Who It's For
The ASUS ROG Kithara is a co-development between ASUS and HIFIMAN, and that partnership is the whole pitch: HIFIMAN's planar magnetic know-how wrapped in ROG's gaming tuning. The drivers here are 100 mm ROG-tuned HIFIMAN planar magnetic units, and the frequency range is genuinely wide at 8 Hz – 55 kHz. ASUS tunes them for a balanced signature with crisp, detailed mid-highs and enhanced bass, which is a sensible target when you need to hear footsteps, dialogue and explosions in the same session.
The open-back architecture is the defining feature. It creates a spacious, natural soundstage with clear separation across bass, mids and treble, and planars are chosen precisely because the diaphragm moves uniformly rather than from a single point — the result is clean, resonance-free reproduction with fast transient response. That combination is why open-back planars get recommended for films and immersive games: the sense of space is the point, and dialogue stays intelligible even when the mix gets busy.
Then there is the practical side, and this is where the Kithara pulls ahead for mixed use. You get an on-cable full-band MEMS boom microphone with a 20 Hz – 20 kHz response and high signal-to-noise ratio for clean voice pickup. You get a 1.8 m dual 3.5 mm cable with a 3-in-1 plug system covering 3.5 mm single-ended, 6.3 mm single-ended and 4.4 mm balanced, plus a separate 1.8 m boom mic cable, a USB-C to dual 3.5 mm adapter, and two sets of ear cushions — one hybrid fabric, one leatherette. The headband adjusts across eight levels inside a metal frame with metal hinges, and the whole thing weighs 11.2 ounces.
Who should buy it? Anyone who wants a single wired headset that works with a DAC, an amp, a PC, a console and a mobile device without hunting for adapters, and who needs a mic that does not sound like a afterthought. It is also the better pick of the two if you watch films on a console or a laptop and want the mic for party chat at the same time. Who should skip it? People who need isolation, people who want wireless, and anyone who mostly listens in a room with other people — open-back means everyone hears your film.
• Best for movies at a desk with a long cable → Dekoni Audio Blue. The 3 m detachable cable and comfortable hybrid pads suit couch-and-desk viewing, and the semi-open cups keep some bass weight.
• Best for movies plus voice chat → ASUS ROG Kithara. The on-cable MEMS boom mic and dual-cable setup mean you can talk and listen without a separate microphone.
• Best for the widest soundstage → ASUS ROG Kithara. Open-back architecture with 100 mm planar drivers and an 8 Hz – 55 kHz range is built for space and separation.
• Best for pad-rolling and comfort tuning → Dekoni Audio Blue. Two full sets of pads in the box let you change the feel and the tone without buying anything extra.
• Best plug compatibility → ASUS ROG Kithara. 3.5 mm, 6.3 mm, 4.4 mm balanced and USB-C coverage beats a single 6.35 mm cable with an adapter.
• Best for phone or laptop listening out of the box → ASUS ROG Kithara. The USB-C adapter and 3.5 mm cable make it plug-and-play on modern devices.
• Best for quiet-room music listening → Dekoni Audio Blue. The warm, bass-rich, smooth tuning is aimed at enjoyment rather than analysis.
• Best for competitive gaming cues → ASUS ROG Kithara. ROG tuned these drivers with power gamers for detail and transient speed in busy mixes.
If I were buying one of these for a mix of films, games and general listening, I would take the ASUS ROG Kithara Gaming/Audiophile. The open-back 100 mm planar drivers, the plug kit that covers everything from a phone to a balanced amp, and the boom mic make it the more useful object in a real room where movies, chat and games all happen on the same machine. I would pick the Dekoni Audio Blue instead if my priority were pure music listening in a quiet space and I wanted to fine-tune comfort and tone with the two included pad sets. For movies specifically, the Kithara's soundstage and cable flexibility win it for me; the Dekoni wins on warmth and on how pleasant it is to wear for long stretches.
what are the best headphones for audiophiles
There is no single answer, but the two designs here show the split clearly. Dekoni Audio Blue is a 50 ohm planar magnetic headphone tuned for bass extension and a smooth top end, while the ASUS ROG Kithara uses 100 mm ROG-tuned HIFIMAN planar drivers with an 8 Hz – 55 kHz range in an open-back frame. In my opinion, audiophiles who value a wide, spacious presentation lean open-back; those who want a warmer, easier listen lean toward the Dekoni tuning.
what are the best wireless headphones for audiophiles
Neither of these is wireless, and that is worth stating plainly. Dekoni Audio Blue is a wired headphone with a 6.35 mm jack and a 3 m detachable cable, and the ASUS ROG Kithara is a wired headset using 3.5 mm, 6.3 mm, 4.4 mm balanced or a USB-C adapter. If wireless is a requirement, look elsewhere; if you want a planar driver fed by a proper cable, both of these are built for that.
what are the best bluetooth headphones for audiophiles
Again, Bluetooth is not part of either spec sheet. The Kithara lists a battery average life of 70 hours, but its connectivity is wired through USB-C and analogue plugs rather than Bluetooth, and the Dekoni Blue is wired only with no battery at all. For Bluetooth listening you would need a different product entirely.
what is the best headphones for audiophiles
It comes down to what you are plugging into and what you are doing. For a quiet room, music-first setup with swappable pads and a long cable, I recommend Dekoni Audio Blue. For a single wired headset that handles movies, gaming and voice chat across a PC, console, DAC or phone, I recommend the ASUS ROG Kithara. Check the current price on Amazon for both before you decide, since that is the one number this comparison deliberately leaves out.
