• OneOdio A71 — biggest strength: a dual-duty coiled cable with both 6.35mm and 3.5mm plugs, plus a 90° swiveling earcup for single-ear monitoring and a share-audio port so a second pair can plug straight in. No adapter hunting, no splitter.
• OneOdio A71 — biggest trade-off: the design leans toward comfort and versatility rather than maximum passive isolation, and at 290 g with a coiled cable it is clearly a home/studio tool rather than a travel-first pair.
• Superlux HD667 — biggest strength: a closed-back, metal-and-plastic build with 40mm neodymium drivers and a 2 m detachable cable that carries an in-line volume control — genuinely useful when your hands are on sticks.
• Superlux HD667 — biggest trade-off: it is a specialist. The 335 g weight and drummer-first tuning make it less of a general-purpose listening headphone, and the shorter feature list is aimed at one job.
• Who each pick is for: OneOdio A71 for DJs, home producers, podcasters and multi-device users who want one cable that fits everything. Superlux HD667 for drummers and performers who need isolation and on-the-fly level control.
The A71 is built around convenience, and the spec sheet shows it. The standout feature is the dual-duty cable: it terminates in gold-plated 3.5mm and 6.35mm plugs, so the same headphones move between a laptop, an amp, a mixer, a keyboard or an electric drum kit without you digging for an adapter. For anyone who works across several sources in a session, that is a real quality-of-life win rather than a marketing bullet.
The second thing that matters for monitor work is the 90° swiveling earcups. That lets you rotate one cup away for single-ear monitoring — the classic move when you are cueing a track, checking a mix against the room, or keeping one ear open for a conversation. The share-audio port is a nice touch too: a second pair of headphones plugs into the A71 and hears exactly what you hear, no splitter required.
Audio-wise, the A71 runs 32 ohm impedance, a 20Hz–20KHz range and 110 dB sensitivity, with a dynamic driver. In practical terms, that low impedance and high sensitivity mean it plays loudly from modest sources like a phone, laptop or interface headphone out. The description points to powerful bass, clear vocals and crisp highs. Physically it's 290 g with soft protein-leather cushions, an adjustable stretchable headband, and a foldable design with both earcups swiveling inward, plus a jack-lock system on the cable and a mic button for play/pause and calls.
Buy it if you are a DJ, home-studio producer, podcaster or multi-instrumentalist who wants one wired headphone that connects to everything and stays comfortable for long sessions. Skip it if you need maximum external-noise blocking in a loud room, or you want a headphone tuned specifically for acoustic drum monitoring.
The HD667 is a purpose-built tool, and the name says it: Drummer Isolation Headphones. Everything about the spec sheet points to one scenario — being surrounded by a lot of noise and needing to hear a clean reference anyway. The closed-back design with premium ear cushions is explicitly there to block external sound so you can focus on detail, which is exactly what you want when there's a kit, a bass amp and a guitarist in the same room.
The driver spec is the interesting part. Superlux fits 40mm neodymium dynamic drivers with 102 dB sensitivity and a 10Hz–20,000Hz frequency response, at 32 ohm impedance. That 10Hz low-end extension is the kind of figure a drummer or bassist notices — it suggests the headphone was voiced to keep low-frequency information present rather than trimmed. The company frames its whole approach around "natural sound reproduction" without a prestige markup, and the feature set matches that philosophy: functional, focused, no extras.
Where the HD667 earns its place is the cable. The 2 m detachable cable includes an in-line volume control, which is exactly the kind of feature that sounds minor until you're mid-take and need to drop your cue level without reaching for a mixer. The gold-plated stereo mini plug plus a 3.5mm-to-6.3mm adapter covers electronic drum kits, acoustic drum monitoring, bass, keyboards and guitar amps. It folds for transport and ships with a soft velvet pouch and a protective case, and it's covered by a 1-year manufacturer warranty.
The trade-off is weight and focus. At 335 g without the cable it's the heavier of the two, and its whole identity is built around isolation and percussion work. Buy it if you're a drummer or live performer who needs to hear a click and a mix through heavy ambient noise. Skip it if you want a single headphone for casual listening, gaming and general studio odd-jobs.
Side-by-Side: Which Should You Choose?
• Best for isolation in a loud rehearsal room → Superlux HD667. Closed-back design with premium cushions is the whole point of the model.
• Best for connecting to many different sources → OneOdio A71. Dual 3.5mm and 6.35mm plugs on one coiled cable, no adapter needed.
• Best for on-the-fly level control while playing → Superlux HD667. The in-line volume control on the detachable cable is a performer's feature.
• Best for low-end extension on paper → Superlux HD667. A 10Hz–20,000Hz rating versus 20Hz–20,000Hz on the OneOdio.
• Best for sharing what you hear → OneOdio A71. The share-audio port feeds a second pair directly.
• Best for lighter long-session wear → OneOdio A71. 290 g versus 335 g, plus protein-leather cushions and a stretchable headband.
• Best for a two-person jam or co-listening session → OneOdio A71. Wired music sharing is built in.
In my opinion, most people shopping "DJ monitor headphones" should buy the OneOdio A71. It covers more ground: dual plugs, a coiled cable, swiveling cups for single-ear monitoring, a share port, and a lighter build. That combination fits DJs, home producers and multi-device users better than a specialist can.
I'd pick the Superlux HD667 only if your job is loud, percussive and live — drumming, rehearsal rooms, stage monitoring — where closed-back isolation and an in-line volume control beat versatility. If that's your world, it's the more focused tool.
what is studio monitor headphones
Studio monitor headphones are wired over-ear headphones designed to reproduce audio accurately for recording, mixing and monitoring rather than to flatter music. Both the OneOdio A71 and Superlux HD667 are over-ear, wired, dynamic-driver designs with 32 ohm impedance and a 20,000Hz top end, built for exactly that kind of work.
why do djs wear headphones
DJs wear headphones to cue the next track privately while the main system plays to the crowd, and to monitor a mix without disturbing the room. That's why a swiveling earcup matters — the OneOdio A71 rotates 90° so you can keep one ear on the booth and one on the music.
why djs wear headphones
For the same practical reason: headphones let a DJ hear what the audience can't yet hear, and they keep monitoring contained. A closed-back design like the Superlux HD667 blocks outside sound, which is useful when the room itself is loud.
why do djs need headphones
A DJ needs headphones to beatmatch, cue and check levels before a track goes live — the mixer's output alone doesn't tell you what's coming next. Low impedance (32 ohm on both models here) and high sensitivity (110 dB on the A71, 102 dB on the HD667) mean either can be driven to usable volume from typical DJ and interface outputs.
