• Dekoni Audio Blue — biggest strength: A semi-open, over-ear planar magnetic headphone built around the Fostex T50RP MK3 platform, with two sets of Dekoni ear pads in the box (one Hybrid, one Elite Velour) and a detachable 3m 1/4-inch cable.
• Dekoni Audio Blue — biggest trade-off: It's a wired, full-size, semi-open headphone with no noise control, so it's a stay-at-home listening tool, not a commute or travel companion.
• ARTTI T10 — biggest strength: A 14.2mm dual-magnetic-circuit planar driver in a stainless steel in-ear body, with interchangeable 3.5mm and 4.4mm plugs and a detachable OFC cable.
• ARTTI T10 — biggest trade-off: It's an in-ear, so fit and tip choice matter more, and the smaller driver simply can't move the same air as a full-size over-ear.
• Who each pick is for: Dekoni Audio Blue for the desk-bound listener who wants a comfortable, serviceable over-ear; ARTTI T10 for the mobile listener, gamer, or musician who wants planar sound in a pocket-sized package.
The Dekoni Audio Blue is, at heart, a Fostex T50RP MK3 with Dekoni's fingerprint all over it. The driver is Fostex's proprietary Regular Phase diaphragm — copper foil etched onto polyimide film, driven by a neodymium magnet — and it's a genuine planar magnetic design, not a dynamic driver dressed up to look like one. Impedance sits at 50 ohm and the rated frequency range runs 20 Hz to 20,000 Hz. Dekoni describes the tuning as fun, with strong bass extension and a smooth top end, which lines up with what the T50RP family is known for.
What makes this particular version interesting is the physical package. You get two pairs of Dekoni pads — one Hybrid and one Elite Velour — plus special-edition blue ear cups and a redesigned inner baffle. The Hybrid pad uses fenestrated sheepskin on its inner face, which Dekoni says helps bring back some of the midrange that the stock T50RP MK3 tends to lose. The frame is semi-open, so sound can breathe rather than sit trapped against your ears, and the 3m detachable cable terminates in a 1/4-inch plug, with a 1/4-inch-to-1/8-inch adapter included. It ships with a blue carrying case.
Who should buy it: someone who listens mostly at a desk or in a quiet room, wants an over-ear planar they can pad-roll and repair rather than replace, and values comfort over portability. The pad swapping is a real feature, not a gimmick — it lets you nudge the tuning and the feel of the headphone without buying anything else.
Who should skip it: anyone who needs isolation. There is no noise control here, and a semi-open over-ear leaks sound both ways. If you listen on trains, planes, in an open office, or while gaming with a mic, this is the wrong shape of product. It's also wired-only and bulky, so it isn't a pocketable option. And 50 ohm planar drivers generally reward a bit of clean amplification rather than a weak phone jack — worth keeping in mind if your main source is a laptop headphone out.
The ARTTI T10 (sold as the T10 Pro) takes the opposite approach: same driver technology, completely different form factor. Inside each earpiece is a 14.2mm planar magnetic driver with a dual magnetic circuit — a genuinely large driver for an in-ear. Impedance is a low 16.5 ohm, THD is rated at ≤1.5%, and the frequency range covers 20 Hz to 20 kHz. ARTTI's own description points to rich bass, smooth mids, and crisp highs with minimal distortion, which is the classic pitch for a well-implemented planar IEM.
The practical details are where the T10 earns its place. The housing is stainless steel in black, so it feels substantial rather than plasticky. The cable is detachable OFC, and — this is the standout — the plugs are interchangeable between standard 3.5mm and balanced 4.4mm. That means the same earphone can plug into a phone or laptop on one end of the day and a balanced output on a dedicated player or DAC/amp on the other. It's wired, with a 3.5mm jack as the base connection, and it includes a media control remote on the cable plus sound isolation from the in-ear seal. In the box: cable, ear tips, and a user manual, with a one-year warranty.
Who should buy it: gamers who want positional clarity and low distortion, musicians and singers who need a reliable wired monitor that can run off different outputs, and anyone who wants planar sound without committing to a full-size headphone and a desk setup. The sound isolation is a real advantage over the Dekoni Blue — a proper in-ear seal blocks a meaningful amount of outside noise.
Who should skip it: people who dislike things in their ears, or who find IEM fit fussy. Tip selection and insertion depth drive both comfort and bass response, and if you don't get the seal right, you won't hear what the driver can do. The smaller driver also can't match the physical scale of a full-size over-ear — planar or not, 14.2mm of diaphragm moves less air than a T50RP-style driver. And while the metal shell is durable, it's still an in-ear with a cable; it won't survive the same abuse as a cheap plastic beater pair.
Side-by-Side: Which Should You Choose?
• Best for portability and travel → ARTTI T10. A stainless steel in-ear with a detachable cable fits in a pocket; the Dekoni Blue does not.
• Best for blocking outside noise → ARTTI T10. It lists sound isolation; the Dekoni Blue has no noise control and is semi-open by design.
• Best for desk and home listening → Dekoni Audio Blue. The 3m detachable 1/4-inch cable and semi-open acoustic design are built for a stationary setup.
• Best for gamers and musicians → ARTTI T10. Low 16.5 ohm impedance, ≤1.5% THD, and 3.5mm/4.4mm swappable plugs make it easy to move between a controller, a phone, and a balanced rig.
• Best for tuning flexibility and serviceability → Dekoni Audio Blue. Two pad sets and a user-replaceable cable let you change the sound and fix wear over time.
• Best for low-impedance, easy-to-drive listening → ARTTI T10. At 16.5 ohm it's far easier to drive from modest sources than the 50 ohm Dekoni Blue.
• Best for large-scale, roomy presentation → Dekoni Audio Blue. A full-size semi-open planar over-ear simply presents music differently than any in-ear can.
If I had to pick one for myself, I'd take the ARTTI T10. In my opinion, it's the more versatile product: planar driver, low 16.5 ohm impedance that plays nicely with everyday sources, swappable 3.5mm and 4.4mm plugs, sound isolation, and a metal body that travels well. That covers gaming, music, and monitoring in one small package. I'd only steer toward the Dekoni Audio Blue if I were setting up a dedicated quiet-room listening station and wanted a full-size, semi-open over-ear I could pad-roll and keep running for years. Both are legitimate picks — they just answer different questions.
They solve different problems. The Dekoni Blue gives you a full-size semi-open over-ear with two pad sets and a 3m 1/4-inch cable. The T10 gives you a pocketable in-ear with swappable plugs. If you listen at a desk, the Dekoni wins; if you listen anywhere else, the T10 does. Check the current price on Amazon for both before deciding.
There's no single answer — they're different form factors. The Dekoni Blue uses a Fostex Regular Phase planar driver at 50 ohm with a semi-open, over-ear presentation. The T10 uses a 14.2mm dual-magnetic planar driver at 16.5 ohm with ≤1.5% THD in a sealed in-ear. Over-ears generally sound bigger and more open; in-ears generally sound more immediate and isolate better.
Yes. ARTTI positions it for gamers, and the low 16.5 ohm impedance, ≤1.5% THD, and included media control cable make it a sensible wired gaming option. You'll want a good seal for consistent bass and positional cues.
It's not mandatory, but at 50 ohm with a planar driver, the Dekoni Blue benefits from a source with some clean power behind it. The ARTTI T10, at 16.5 ohm, is much easier to drive straight from a phone or laptop.
