If you want a hard protective travel case for your Beats on-ear or over-ear headphones, choose co2CREA Beats Studio Pro/Studio3/Solo4/Solo3; if you need actual studio reference headphones for mixing, monitoring and critical listening, choose SAMSON SR850B. That is the whole comparison in one line — one product carries your headphones, the other is the headphone. Since I'm framing this around studio headphones, most readers land here with two very different jobs in mind: protecting a pair of Beats they already own, or buying a wired reference can for the desk. And yes, comfort matters for glasses wearers in both cases, so I'll keep coming back to that.
• co2CREA case — biggest strength: a hard EVA shell that is shockproof, dustproof and water resistant, built specifically around Beats Studio Pro, Studio3, Solo4, Solo3 and Solo Pro, with a soft anti-static lining and a mesh pocket for accessories.
• co2CREA case — biggest trade-off: it is a case only. No headphones included, no audio function at all, and it does nothing for sound quality.
• SAMSON SR850B — biggest strength: genuine studio intent — semi open back for a wide soundstage, 50 mm dynamic drivers with rare earth magnets, 10 Hz–30 kHz frequency range and 32 ohm impedance that plays nicely with interfaces, mixers, laptops and phones.
• SAMSON SR850B — biggest trade-off: it's wired, it's semi open (so it leaks sound and lets sound in), and it has no noise control or Bluetooth whatsoever.
• Who the co2CREA is for: anyone who already owns Beats Studio Pro, Studio3, Solo4, Solo3 or Solo Pro and wants to carry them without scratches, dents or dust.
• Who the SR850B is for: musicians, producers and audio engineers — plus everyday listeners who want an accurate, comfortable over-ear wired headphone for long sessions.
The co2CREA case is a storage and transport solution, not a listening device, and it's honest about that: the listing states plainly that you're buying the case only and the Beats headphones are not included. What you get is a molded hard EVA shell measuring roughly 7.24 x 5.91 x 3.62 inches, with a nylon exterior and a soft anti-static lining inside. The point of that lining is to keep the finish on your Beats from picking up bumps, dents and scratches while the hard shell absorbs drops and knocks.
Who should buy it? If you own any of those Beats models and you move them around — commute, gym bag, flights, studio-to-home — this is a sensible way to stop treating a several-hundred-dollar pair of headphones like a loose item in a backpack. Who should skip it? Anyone shopping for sound. If you don't own Beats in that list, or you're looking for an actual headphone to listen with, this isn't your product. And if you're a glasses wearer specifically hunting a wireless headband headphone for comfort, note that this case doesn't change how your Beats sit on your head — it only protects them when they're off.
SAMSON SR850B: Who It's For
The SR850B is the opposite kind of purchase: it's the thing you put on your head. Samson positions it as a professional studio reference headphone for musicians, producers and audio engineers, and the spec sheet backs that up — 50 mm dynamic drivers with rare earth magnets, a 10 Hz to 30 kHz frequency range, 98 dB sensitivity and 32 ohm impedance. Low impedance like that means it doesn't demand a dedicated headphone amp; it'll run from an audio interface, a mixer, a laptop or a mobile device, and it ships with a 3.5 mm plug plus a 1/4 inch gold plated adapter for the bigger jacks.
The headline design choice is the semi open back. Unlike a closed back headphone, it deliberately lets some sound leak out and in, and the payoff is stereo imaging — a wider, more natural, more speaker-like soundstage. That's exactly what you want when you're mixing or monitoring and need to hear where instruments sit in the space. It's also why it's a poor pick for a noisy train or a shared open office: semi open means your music escapes and the room comes in.
Comfort is clearly a priority here. It's an over-ear fit with soft velour ear cushions and a self-adjusting headband, and the design goal is a secure fit across long sessions without fatigue. For glasses wearers, that combination is genuinely relevant — velour is softer against the temple arms than stiff leatherette, and a self-adjusting headband spreads the clamp rather than pinching it in one spot. There's no active noise cancellation and no wireless mode at all; this is a wired, reference-first headphone. It carries a 2 year manufacturer warranty.
Side-by-Side: Which Should You Choose?
• Best for actual studio work (mixing, monitoring, recording) → SAMSON SR850B. Semi open back, 50 mm drivers, 10 Hz–30 kHz.
• Best for wide soundstage and stereo imaging → SAMSON SR850B. The semi open design is the whole reason it exists.
• Best for travel and transport → co2CREA case. Hand strap, strong zipper, mesh pocket, purpose-built cavity for Beats.
• Best for long listening sessions with glasses → SAMSON SR850B. Soft velour cushions plus a self-adjusting headband.
• Best for quiet, isolated listening environments → co2CREA case is irrelevant here — but the SR850B is the wrong tool. Semi open leaks; there's no noise control.
• Best for plug-and-play with phones, laptops and interfaces → SAMSON SR850B. 32 ohm impedance and a 3.5 mm jack with a 1/4 inch adapter included.
• Best if you want zero audio compromise and zero setup → neither, honestly. The case adds no sound; the SR850B is wired by design.
If I had to pick one, I'd pick the SAMSON SR850B — because you're here reading about studio headphones, and only one of these two products is a headphone. In my opinion, the semi open back, 50 mm drivers and velour over-ear comfort make it the more useful purchase for mixing, monitoring and long sessions, and the self-adjusting headband and soft cushions are the details I'd want as a glasses wearer. I'd buy the co2CREA case only as an accessory — specifically if I already owned Beats Studio Pro, Studio3, Solo4, Solo3 or Solo Pro and wanted to stop scratching them. Buy the case for the headphones you have; buy the SR850B for the sound you want.
FAQ
how to connect studio headphones
how to test studio headphones
A practical check is channel balance and imaging: play a track you know well and listen for whether instruments sit where you expect them across the stereo field. The SR850B's semi open design is built to make that stage feel wide, and its 10 Hz–30 kHz range means you can sweep low bass and high detail to hear what the drivers are doing. Also check fit — a self-adjusting headband and velour pads should sit securely without pressure points.
how to bluetooth studio headphones
You don't, on the SR850B — it has no Bluetooth and no wireless mode at all; connectivity is a 3.5 mm wired jack. If wireless is a hard requirement, you'd need a separate Bluetooth transmitter or a different headphone entirely. The co2CREA case, for the record, is not a headphone and has no connectivity of any kind.
how to pair beats studio headphones
Pairing is a Beats-side process, not something the co2CREA case does — the case is storage only and includes no electronics. You'd put your Beats Studio Pro, Studio3, Solo4 or Solo3 into pairing mode and connect from your phone or computer as usual. The case's job starts when you're done listening: it holds the folded headphones, cables and small accessories so they travel safely.
