If you want a replacement headband kit to repair a Studio Pro x Kim Kardashian Edition 2024 headphone, choose Knomix Studio Pro x; if you need a complete pair of wired studio headphones for mixing, monitoring or playing an instrument, choose NUBWO HD01. That is the honest split here, because these two products are not really competing for the same job. One is a repair part. The other is a finished pair of headphones.
• Knomix Studio Pro x — biggest strength: it is a purpose-built replacement headband for one specific headphone model, sold with the screwdriver and four screws needed to fit it.
• Knomix Studio Pro x — biggest trade-off: it is not a headphone. It makes no sound, and it only fits the Studio Pro x Kim Kardashian Edition 2024 over-ear headphone.
• NUBWO HD01 — biggest strength: a complete wired studio headphone with angled 45mm dynamic drivers, 50 ohm impedance, a 20Hz–40kHz range and dual twist-lock 3.5mm ports.
• NUBWO HD01 — biggest trade-off: it is wired only, so there is no wireless freedom, and it expects you to work at a desk, mixer or amp.
• Who the Knomix kit is for: someone who already owns the Studio Pro x headphone and has a snapped or worn top band.
• Who the NUBWO HD01 is for: someone who wants one pair of wired over-ear headphones for recording, mixing, DJ work or practice.
Let me be blunt about what this product is, because the listing title is long and easy to misread. The Knomix Studio Pro x item is a top headband replacement and repair kit, not a headphone. Knomix describes it as compatible with the Studio Pro x Kim Kardashian Edition 2024 wireless Bluetooth over-ear headphone, and the package contains one replacement headband, one screwdriver and four screws. That's the whole kit.
The headband measures 9.05 by 1.06 inches (roughly 23 x 2.7 cm), and Knomix flags that dimension in the listing for a good reason: if you don't check it against your broken band first, you can order the wrong repair part. The band itself is plastic, and Knomix states it isn't easy to break and invites you to press it a few times on arrival to check for a defect, contacting them if something is wrong. The color is pink, matching the Moon variant, and there's a six-month warranty on the part.
NUBWO HD01: Who It's For
The NUBWO HD01 is the opposite kind of product: a real, complete pair of wired over-ear studio headphones. The headline spec is a pair of angled 45mm dynamic drivers. NUBWO's reasoning is that angling the drivers toward your eardrums gives more accurate spatial imaging, and that the ergonomic structure also improves comfort, boosts passive isolation and reduces sound leakage. Whether or not you buy every word of the marketing, the design logic is sound — angled drivers are a familiar approach in monitoring headphones, and less leakage matters when you're tracking with a microphone open.
The numbers back up the studio intent. Impedance is 50 ohm, sensitivity is 101 dB, and the frequency range runs 20Hz to 40kHz, which is why NUBWO can put "Hi-Res" in the title. The 40kHz ceiling only matters if your source and files go that high, but it's a genuine spec, not a slogan. Weight is 241 grams, which is light for an over-ear closed-back design, and the enclosure is plastic with polyurethane (PU) ear pads in an oval, over-ear shape. NUBWO rates it for adults and backs it with a two-year warranty.
The connectivity is where the HD01 gets interesting. It's wired only, with a 3.5mm jack and a 6.35mm jack supported. You get two detachable cables in the box — a 1.5m 3.5mm-to-3.5mm and a 2.5m 3.5mm-to-3.5mm/6.35mm — plus a gold-plated screw-on 6.35mm adapter. The dual 3.5mm ports use a twist-lock design: plug, twist, lock. NUBWO says this eliminates accidental disconnections during mixing, DJ sets or live performance, and it also enables audio sharing between two listeners.
Who should buy it? In my opinion: anyone who needs one wired headphone for a mixer, amp, audio interface or DJ setup, and who values a locking connection over wireless convenience. The 2.5m cable and screw-on adapter suit a desk or a stage. Who should skip it? Anyone who wants Bluetooth, or who needs a replacement part for an existing headphone. This is a whole product, not a component.
• You need to repair a Studio Pro x Kim Kardashian Edition 2024 headband → Knomix Studio Pro x. It's the only one of the two built for that job, and it ships with the screwdriver and four screws.
• You need headphones that actually play audio → NUBWO HD01. The Knomix kit has no drivers, no cable and no sound.
• Best for studio and DJ use → NUBWO HD01. Dual twist-lock 3.5mm ports, a 2.5m cable and a 6.35mm screw-on adapter are aimed squarely at mixers, amps and live gear.
• Best for accurate monitoring → NUBWO HD01. Angled 45mm dynamic drivers, 50 ohm impedance, 101 dB sensitivity and a 20Hz–40kHz range.
• Best for long sessions → NUBWO HD01. 241 grams, oval over-ear PU pads and passive sound isolation.
• Best for wireless listening → neither. The HD01 is wired only, and the Knomix item isn't a headphone at all. If wireless is a must, look elsewhere.
• Best for a quick, low-risk fix → Knomix Studio Pro x. One band, one screwdriver, four screws, six-month warranty.
• Best for warranty cover on a complete headphone → NUBWO HD01. Two years versus six months on the Knomix part.
• Best for two people listening at once → NUBWO HD01. The dual ports allow audio sharing; the Knomix kit does nothing of the sort.
If I had to pick one of these two for myself, I'd buy the NUBWO HD01, because it's an actual pair of wired studio headphones I could use every day — angled 45mm drivers, dual locking ports, two detachable cables and a two-year warranty. The Knomix Studio Pro x is a good, specific fix for a specific broken headband, and if that's your situation it's the right purchase. But it can't replace a headphone, and the HD01 is the one that earns its place on a desk.
what are the best wired studio headphones
There's no single answer, because "best" depends on your setup. What I can say is that the NUBWO HD01 ticks the boxes that matter for studio use: angled 45mm dynamic drivers, 50 ohm impedance, 101 dB sensitivity, a 20Hz–40kHz range and a wired 3.5mm/6.35mm connection with locking ports. Judge any candidate against specs like those.
what are wired headphones
Wired headphones connect to your device with a physical cable instead of Bluetooth. The NUBWO HD01 is a wired over-ear model with a 3.5mm jack and a 6.35mm jack, and it includes a 1.5m and a 2.5m detachable cable plus a gold-plated screw-on 6.35mm adapter. No charging, no pairing, no latency.
what headphones do professional studios use
Studios tend to favour closed-back, wired, over-ear designs for tracking and monitoring, because a cable avoids wireless latency and closed cups reduce leakage into microphones. The NUBWO HD01 follows that formula: closed-back, over-ear, 45mm angled drivers, passive sound isolation and a locking 3.5mm connection. That said, no single model suits every studio.
are all studio headphones wired
No, but wired is still the norm for monitoring and mixing. The NUBWO HD01 is wired only — 3.5mm and 6.35mm — which is typical of the category. If you specifically want wireless, you're shopping outside the classic studio-headphone mould, and neither product here is the answer.
