• HIFIMAN Deva-Pro – biggest strength: A planar-magnetic driver with Stealth Magnet geometry and an ultra-thin NEO supernano diaphragm, aimed at low distortion and fast, detailed response.
• HIFIMAN Deva-Pro – biggest trade-off: At 93.5dB sensitivity and 18Ω, it rewards a decent source, and the wired version needs the separately sold Bluemini R2R module if you ever want wireless.
• Linsoul HarmonicDyne Romantic – biggest strength: A 60mm bamboo fiber dynamic driver with 107dB sensitivity, so it plays loudly and cleanly from phones, laptops and desktop amps alike.
• Linsoul HarmonicDyne Romantic – biggest trade-off: 64Ω and a dynamic driver mean a different presentation than planar, and its open-back design leaks sound both ways.
• Pick the HIFIMAN Deva-Pro if you want planar texture, a modular design and don't mind feeding it properly.
• Pick the Linsoul HarmonicDyne Romantic if you want plug-and-play versatility, a lighter frame (235g vs 360g) and a 4.4mm balanced cable included.
The Deva-Pro is built around HIFIMAN's planar-magnetic driver technology, and the headline here is the Stealth Magnet design. Instead of a conventional magnet array that the sound waves have to fight through, the shaped magnets are meant to let those waves pass with far less diffraction turbulence. In plain terms, that's a distortion-reduction story — the goal is a cleaner, more accurate, full-range output rather than a colored, "fun" tuning.
The second piece is the NEO supernano diaphragm, which HIFIMAN says is 80% thinner than earlier designs. A thinner, lighter diaphragm moves faster and settles quicker, which is what gives planar headphones their reputation for speed and image detail. The spec sheet backs the general profile: 20Hz–20kHz, 18Ω impedance and 93.5dB sensitivity. That 18Ω figure looks easy on paper, but the 93.5dB sensitivity tells you it still wants real current — a phone dongle will make sound, a proper amp will make it sing.
Physically, it's a 360g over-ear with a contoured earpiece shape and what HIFIMAN describes as a lightweight, ergonomically accurate headband for long sessions. The genuinely interesting design choice is the socket: the left cup accepts both a dual-sided unbalanced 3.5mm cable and a single-sided 3.5mm balanced cable, and that same left socket is where the Bluemini R2R module connects if you buy it separately.
Linsoul HarmonicDyne Romantic 60mm: Who It's For
The Romantic takes a completely different route. Its driver is a self-developed 60mm bamboo fiber composite unit. The natural damping of that material is designed to keep the diaphragm moving evenly, which is Linsoul's way of tackling distortion and the harsh ringing that can creep into lesser dynamic drivers. The claimed stiffness-to-weight ratio is what allows the fast response — the spec sheet describes it staying punchy during big orchestral swells rather than smearing under complex passages.
Then there's the sensitivity: 107dB. That's the number that matters most for everyday buyers. Combined with 64Ω impedance, it means this headphone is happy on a smartphone, a laptop headphone jack or a desktop amplifier. It's the opposite philosophy from the Deva-Pro — instead of demanding better gear, it's designed to perform across whatever you already own. Frequency response is listed as 10Hz–50kHz, a wider stated range than the HIFIMAN.
The open-back earcup structure widens the stage and helps with instrument and vocal positioning, at the cost of isolation in both directions — the sheet lists passive noise cancellation, which for an open-back really means it lets the room in and lets your music out. Comfort is clearly a priority: 235g total weight, an adjustable headband, and protein leather earpads with a "soccer net" fabric lining for breathability and even pressure distribution. The included cable is a hybrid braided design — silver-plated oxygen-free copper plus single-crystal copper, 4-strand, 924 cores total — terminating in a 4.4mm balanced connector, which helps channel separation. A one-year warranty is listed.
Buy it if you want an open-back that works from almost any source, value a light frame and plush pads, and want a balanced cable included from day one. Skip it if you specifically want planar-magnetic texture, or if you need any isolation at all.
Side-by-Side: Which Should You Choose?
• Best for source flexibility → Linsoul HarmonicDyne Romantic 60mm. 107dB sensitivity means it runs well from phones, laptops and amps alike.
• Best for long-session comfort on weight alone → Linsoul HarmonicDyne Romantic 60mm. 235g versus 360g is a real difference over hours.
• Best for a future wireless upgrade → HIFIMAN Deva-Pro Over-Ear Open-Back. The left socket takes the Bluemini R2R module (sold separately).
• Best for cable flexibility out of the box → Linsoul HarmonicDyne Romantic 60mm. It ships with a 4.4mm balanced hybrid braided cable.
• Best if you already own a headphone amp → HIFIMAN Deva-Pro Over-Ear Open-Back. 93.5dB sensitivity rewards proper amplification.
• Best for the widest stated frequency range → Linsoul HarmonicDyne Romantic 60mm. 10Hz–50kHz versus 20Hz–20kHz.
• Best for gaming and studio monitoring at a desk → either, but lean Linsoul for the lighter frame and breathable pads.
In my opinion, the Linsoul HarmonicDyne Romantic 60mm is the safer buy for most people. The 107dB sensitivity and 235g frame mean it works immediately with whatever you plug it into, and the included 4.4mm balanced cable is a nice touch you don't have to shop for. I'd pick the HIFIMAN Deva-Pro only if planar-magnetic sound is specifically what you're chasing, or if the idea of adding the Bluemini R2R module later for wireless appeals to you — and I'd only do that knowing I have a source with enough current to drive it. For a first open-back, the Romantic is the lower-friction choice.
Its 18Ω impedance looks friendly, but 93.5dB sensitivity means it wants current. It will play from a phone, but a dedicated amp is what gets the most out of the planar driver.
Yes. At 107dB sensitivity and 64Ω it's designed to run from smartphones, laptops and desktop amps without needing specialized gear.
Neither, really. Both are open-back designs. The Romantic lists passive noise cancellation, but open-back headphones inherently leak sound in and out — buy closed-back if isolation is the priority.
The Linsoul HarmonicDyne Romantic at 235g, with protein leather pads and a breathable fabric lining. The HIFIMAN Deva-Pro is listed at 360g.
