If you want a lighter, planar-magnetic headphone with low 18Ω impedance that's easy to drive from whatever source you already carry, choose HIFIMAN Deva-Pro Over-Ear Open-Back; if you need a bigger 50 mm dynamic driver, a wider 10 Hz–28 kHz frequency range, a self-adjusting headband and a detachable 3 m cable with a zipper case, choose Behringer Omega Open-Back Hi-Fi. Both are open-back, over-ear, wired designs, so if you're shopping for warehouse work, read the isolation trade-off carefully before you commit either way.
• HIFIMAN Deva-Pro, biggest strength: a planar-magnetic driver with HIFIMAN's Stealth Magnet shape and the NEO "supernano" diaphragm, quoted at 80% thinner than earlier designs — paired with 18Ω impedance and 93.5 dB sensitivity, this is a headphone built to sound detailed without demanding a dedicated amp.
• HIFIMAN Deva-Pro, biggest trade-off: this is the wired version, and it ships as a bare headphone — no case, no adapter, and no noise control of any kind. The open-back grille also means everyone near you hears your audio.
• Behringer Omega, biggest strength: a genuinely wide spec sheet for the money-shape of the design — 50 mm neodymium dynamic drivers rated 10 Hz–28 kHz, a self-adjusting headband, a detachable two-sided cable that stretches to 3 m, a gold-plated 3.5 mm to 6.3 mm adapter and a zipper case.
• Behringer Omega, biggest trade-off: it's a dynamic driver at 32Ω with no sensitivity figure published, and at 370 g it's marginally heavier than the HIFIMAN. Like the Deva-Pro, it isolates nothing.
• Pick HIFIMAN Deva-Pro if you care most about fine detail, imaging and long-session comfort, and you're willing to supply your own pouch and adapter.
• Pick Behringer Omega if you want the accessories, a longer detachable cable and a self-adjusting fit handled for you out of the box.
The Deva-Pro's whole argument is driver technology. The Stealth Magnet design is shaped so sound waves pass through the magnet structure rather than being disturbed by it, which HIFIMAN says cuts the diffraction turbulence that smears a waveform. Whether or not you buy the physics pitch, the practical result of that plus the ultra-thin NsD diaphragm is a headphone aimed at speed and low distortion rather than thump. Add 18Ω impedance and 93.5 dB sensitivity and you get something a phone or a cheap desktop DAC can drive to real volume — a meaningful detail if your listening happens at a shared bench or in a locker room rather than at a proper desk rig.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Comfort is the other half of the pitch. At 360 g with contoured earcups that sit around the ear rather than pressing on it, the Deva-Pro is designed for hours rather than minutes, which matters if you're wearing them through a full shift. The ear-side socket arrangement is unusually flexible: the left socket takes a single-sided 3.5 mm balanced cable, while the jack accommodates a dual-sided unbalanced 3.5 mm cable too, and the same left socket accepts HIFIMAN's Bluemini R2R module if you later want to cut the cord.
Who should buy it: listeners who prioritize detail retrieval, imaging and a light-on-the-head feel, and who like the idea of upgrading to a balanced cable or a wireless module later. Who should skip it: anyone who wants a case and a quarter-inch adapter in the package, anyone who needs Bluetooth out of the box, and anyone shopping for the best open ear earbuds for warehouse work — this is a full-size over-ear headphone, not an earbud, and it blocks zero ambient noise.
Behringer positions the Omega as a studio and listening tool, and the spec sheet reads that way. The 50 mm neodymium dynamic drivers are rated from 10 Hz to 28 kHz, which is a wider window at both ends than the HIFIMAN's 20 Hz–20 kHz figure. A wider rating isn't automatically better sound — it's a number, not a review — but it does tell you Behringer designed these for sub-bass rumble and airy top-end extension, and the metal grille behind the driver is there to let that open, roomy presentation breathe.
The practical design choices are where the Omega earns its place. The self-adjusting headband takes the fit question off your plate entirely — you put them on and they settle. The ultra-soft ear cushions are spec'd for extended sessions. The detachable cable runs two-sided and stretches to about 3 m, which is a lot of slack if your source isn't right next to you, and it's replaceable if it fails. Behringer also throws in the small stuff people forget to buy: a gold-plated 3.5 mm to 6.3 mm threaded adapter for pro gear, and a zipper case.
Two honest caveats. First, it's a dynamic driver at 32Ω with no published sensitivity, so while Behringer says the design is optimized for a wide range of devices, I'd expect it to want a little more headroom than the 93.5 dB HIFIMAN from a weak source. Second, at 370 g and with no noise control listed, it's a stay-put headphone, not a walk-around one. Who should buy it: home-studio tinkerers, composers, musicians practicing along to a mix, and anyone who wants the accessories and a long detachable cable included. Who should skip it: buyers who want planar-magnetic detail above all, or who want an on ear headphones for warehouse work solution that swivels, folds, or travels small.
Side-by-Side: Which Should You Choose?
• Best frequency extension on paper → Behringer Omega. 10 Hz–28 kHz versus 20 Hz–20 kHz.
• Easiest to drive from a weak source → HIFIMAN Deva-Pro. 18Ω with 93.5 dB sensitivity is a deliberately undemanding load; the Omega's 32Ω has no sensitivity published.
• Best out-of-the-box kit → Behringer Omega. Detachable 3 m cable, 3.5 mm to 6.3 mm gold-plated adapter, zipper case, self-adjusting headband.
• Best for long sessions on your head → close call, slight edge HIFIMAN Deva-Pro. 360 g versus 370 g, plus contoured earcups designed to clear the ear.
• Best upgrade path → HIFIMAN Deva-Pro. The left socket accepts a single-sided balanced 3.5 mm cable and the Bluemini R2R module sold separately, so wired today can become wireless later.
• Best for shared or noisy spaces → neither. Both are open-back with no noise control, so both leak sound outward and let everything inward. If you need isolation, this whole category is the wrong category.
My Verdict
For most people reading this, I'd buy the HIFIMAN Deva-Pro Over-Ear Open-Back. In my opinion the planar-magnetic driver, the 18Ω/93.5 dB load and the 360 g contoured fit are the three things that actually change how a long listening session feels, and the socket flexibility means you're not locked into one setup. The missing case and adapter are annoyances you can solve for a few dollars; the driver architecture you can't upgrade later.
That said, if you want the cable, adapter and case in one box and you like a self-adjusting headband, the Behringer Omega is the more complete package — that's a legitimate reason to pick it, not a consolation prize. For warehouse work specifically, I'd go Deva-Pro if you value hearing a page or a forklift horn over blocking noise, and I'd avoid both if you need real isolation. Check the current price on Amazon before you decide, since that's the one variable that can flip this recommendation.
FAQ
Probably not. The Deva-Pro's 18Ω impedance and 93.5 dB sensitivity are easy loads for a phone or laptop. The Omega's 32Ω is still modest, though Behringer publishes no sensitivity figure, so a weak output may leave you turning the dial further.
The Behringer Omega is wired only. The Deva-Pro is also wired as sold, but its left socket accepts HIFIMAN's Bluemini R2R module, sold separately, which is the only route to cord-free use on this pair.
Neither is ideal, because both are open-back with no noise control — you'll hear the floor and the floor will hear you. If you want situational awareness and a light fit, the Deva-Pro is my pick; if you need to actually block machinery noise, buy a closed-back pair instead.
It's close. The Deva-Pro is 360 g with contoured cups that fit around the ear; the Omega is 370 g with ultra-soft cushions and a self-adjusting headband that removes fit fiddling. I'd give the edge to the Deva-Pro on weight, and to the Omega on set-and-forget fit.
