How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want studio-grade, wired reference sound for mixing, monitoring and long listening sessions, choose SAMSON SR850; if you need a wireless, sweat-and-swim-proof training companion with built-in music storage, choose DEMICEA Open Ear Sport. These two have almost nothing in common except that they both go on your head — one is a semi-open studio headphone, the other is an open-ear bone conduction sport model. Picking the wrong one for your use case will frustrate you fast, so let's break down exactly where each one wins.
• SAMSON SR850 — biggest strength: semi-open, over-ear design with 50mm dynamic drivers and a 10Hz–30kHz frequency range, built for accurate, fatigue-free critical listening.
• SAMSON SR850 — biggest trade-off: it's fully wired with a 3.5mm jack and no Bluetooth, so you're tethered to your interface, mixer or phone.
• DEMICEA Open Ear Sport — biggest strength: 32g open-ear bone conduction build with IP68 waterproofing, 32GB of built-in storage and Bluetooth 5.3 — no wires, no phone required.
• DEMICEA Open Ear Sport — biggest trade-off: bone conduction sound leaks and can't match the isolation or tonal accuracy of an over-ear studio headphone, and it has no jack at all.
• Buy the SAMSON SR850 if you mix, record, podcast or just want a wired, accurate reference headphone for home and studio.
• Buy the DEMICEA Open Ear Sport if you run, swim, cycle or train and want music without blocking your ears.
The SR850 is a purpose-built studio tool. Samson specs it with 50mm dynamic drivers, a 32-ohm impedance and a frequency response stretching from 10Hz to 30kHz, which tells you the intent: reproduce the whole audible range as evenly as possible rather than hype one part of it. The semi-open, circumaural design is the key detail here. Because the cups aren't fully sealed, air moves through them, which typically translates to a wider, more "open" presentation and less of that pressurized feeling you get from closed-back headphones during a long session. If you've ever pulled off closed headphones after three hours with hot, tired ears, you know why that matters.
Who should buy it? Musicians, podcasters, home-studio producers and anyone who wants a wired reference headphone for critical listening — mixing a track, editing audio, or just sitting back with an album and hearing it the way it was recorded. Who should skip it? Anyone who wants wireless freedom, needs water resistance, or plans to wear headphones while running or swimming. The SR850 is tethered by design, with no Bluetooth and no IP rating, so it's the wrong tool for the gym or the pool.

DEMICEA Open Ear Sport: Who It's For
The DEMICEA Open Ear Sport is the opposite philosophy: built to disappear on your head and survive the outdoors. At just 32g it's remarkably light, and the construction tells the story — a soft liquid silicone casing over a flexible titanium alloy frame that adapts to different head shapes, reinforced with nylon to resist wear and spring back into shape under stress. That's a design aimed squarely at movement: run, jump, sweat, repeat, and the frame forgives you. The matte red finish over ABS, metal and silicone keeps it looking like sport gear rather than office gear.
The headline feature for athletes is IP68 waterproofing. That rating means it's built to handle splashes, sweat and rain, and Demicea explicitly frames it as safe to wear while swimming, with a simple water rinse enough to clean off sweat and grime. If you swim laps or train in wet conditions, that's a genuinely different capability from almost any over-ear headphone, which you'd never submerge. Sound-wise, it uses a bone conduction driver with a 16mm oversized diaphragm and "BassBoost" low-frequency enhancement, with a 20Hz–20,000Hz range and 8-ohm impedance. Bone conduction sits outside your ear canal, so your ears stay open to traffic, training partners and surroundings — a safety and awareness advantage, at the cost of bass depth and isolation compared to a sealed headphone.
Side-by-Side: Which Should You Choose?
• Best for studio mixing and critical listening → SAMSON SR850. The semi-open over-ear design and 50mm drivers are built for accuracy, not workouts.
• Best for swimming and wet training → DEMICEA Open Ear Sport. IP68 waterproofing with a rinse-clean silicone body is the whole point.
• Best for wired, latency-free monitoring → SAMSON SR850. A 3.5mm jack plus the included 1/4-inch adapter plugs straight into interfaces and mixers.
• Best for phone-free playback → DEMICEA Open Ear Sport. 32GB of built-in storage means thousands of tracks with no device attached.
• Best for long, fatigue-free listening sessions → SAMSON SR850. Velour cushions, a self-adjusting headband and a semi-open design reduce ear fatigue over hours.
• Best for awareness of your surroundings → DEMICEA Open Ear Sport. Open-ear bone conduction leaves your ear canal unobstructed.
• Best for wireless convenience → DEMICEA Open Ear Sport. Bluetooth 5.3 with multipoint switching beats being tethered.
• Best for durability under physical stress → DEMICEA Open Ear Sport. The flexible titanium frame and nylon reinforcement are made to flex and recover.
In my opinion, these two don't compete — they solve different problems, so the right call depends entirely on your routine. If your priority is faithful, accurate sound for mixing, recording or serious listening, I'd buy the SAMSON SR850; its semi-open design, 50mm drivers, velour comfort and two-year warranty make it the better reference headphone. If your priority is training — especially swimming — I'd buy the DEMICEA Open Ear Sport for its IP68 build, 32GB offline storage and open-ear awareness. For most casual listeners who just want one pair, I lean SR850 for sound quality and DEMICEA for active, wireless life.
Wired. It connects via a 3.5mm jack and includes a 1/8-inch to 1/4-inch gold-plated adapter for pro gear. There's no Bluetooth, so you're always tethered to your source.
Yes — Demicea rates it IP68 waterproof and states it's safe to wear while swimming, with a simple water rinse to clean off sweat and dirt. That's a capability the SR850 does not have.
For accuracy and mixing, the SAMSON SR850 is the stronger choice thanks to its semi-open over-ear design, 50mm drivers and wide 10Hz–30kHz range. The DEMICEA is tuned for bass impact and open-ear awareness rather than reference accuracy.
Demicea lists up to 8 hours of playback from a 2-hour fast charge using its 4-pin magnetic charging port. The SR850, being wired, doesn't rely on a battery for listening.
No. It has 32GB of built-in storage for offline playback, so you can load thousands of tracks and leave your phone behind — handy for swimming or running.
