If you want to add wireless freedom to a pair of Beats Studio 2 headphones you already own, choose Bolle & Raven Bolle&Raven; if you need to physically repair a broken Beats Studio Pro with a new headband and hinges, choose Adhiper Studio Pro Replacement.
That's the whole decision in one line. These two products look like they belong in the same conversation because both carry "studio" in the name, but they solve completely different problems. One is an electronics upgrade. The other is a mechanical repair kit. Buying the wrong one won't just disappoint you — it will be completely useless for your headphones. So let's sort out which one actually fits your situation.
• Bolle & Raven Bolle&Raven — biggest strength: turns a wired-only Beats Studio 2 into a Bluetooth headphone with built-in mic, on-board controls, and up to 12 hours of playback and talk time.
• Bolle & Raven Bolle&Raven — biggest trade-off: it is locked to the Beats Studio 2.0 model only. It will not work with Beats Solo 2 or any other headphone, so you must check your model first.
• Adhiper Studio Pro Replacement — biggest strength: a complete metal repair set — a pair of hinges, a headband, a screwdriver and four screws — built to match the original parts in size, color and construction, so you can fix a cracked or snapped Beats Studio Pro instead of replacing it.
• Adhiper Studio Pro Replacement — biggest trade-off: it is a parts kit, not an accessory. If your headphones aren't broken, or aren't genuine Beats Studio Pro, it does nothing for you.
• Who each pick is for: Bolle & Raven for the owner of a working but wired Beats Studio 2 who wants to cut the cord; Adhiper for the owner of a broken Beats Studio Pro who wants to keep the pair they already love.
This is a small grey adapter — roughly 1.5 by 2 by 3 inches — that plugs into a Beats Studio 2.0 and effectively converts it into a wireless headphone. The pitch is simple: you already own a good-sounding pair of Beats, they're just tethered to a cable, and this gadget unwires them. Once it's on, you get Bluetooth streaming from both Apple and Android devices, plus on-board controls for volume, song skipping and calls, so you're not reaching for your phone every time you want to change a track.
Who should buy it: someone with a working Beats Studio 2.0 who wants wireless convenience without buying a whole new set of headphones. Who should skip it: anyone with Beats Solo 2, Beats Studio Pro, or any other model. The compatibility note is unusually strict here — Studio 2.0 only — so check the model number on your headphones before you order. If you're not sure, this isn't the product to gamble on.
Adhiper Studio Pro Replacement: Who It's For
The Adhiper set is a repair kit, and it's aimed at a very specific kind of frustrated owner: someone whose Beats Studio Pro still sound fine but whose headband has cracked, whose hinge has snapped, or whose frame has otherwise given out. Instead of paying for a full repair or binning a pair that still works, you swap the broken mechanical parts yourself.
The kit includes a pair of replacement hinges, a replacement headband, a screwdriver and four screws — eight pieces in total. The color is Sandstone, and the enclosure material is a mix of faux leather and leather, which matters because the headband is the part that touches your head all day. Adhiper states the size, color and construction are almost identical to the OEM parts, so fit shouldn't be a guessing game. The brand also backs it with a 12-month warranty and a stated after-sales process: if something's wrong with the package, you contact them and they'll resend or refund.
Who should buy it: owners of genuine Beats Studio Pro headphones with a physical failure in the headband or hinge area, especially anyone comfortable with a small screwdriver. Who should skip it: anyone whose headphones aren't genuine Beats Studio Pro — the brand explicitly warns the set only suits the real thing — and anyone whose problem is electronic rather than structural. A new headband won't fix a dead driver.
Side-by-Side: Which Should You Choose?
• Best for cutting the cord → Bolle & Raven Bolle&Raven. It's the only one of the two that adds wireless playback at all.
• Best for long listening sessions → Bolle & Raven Bolle&Raven, with up to 12 hours of playback and talk time on a charge.
• Best for hands-on tinkerers → Adhiper Studio Pro Replacement. You'll need the included screwdriver and a bit of patience.
• Best for taking calls → Bolle & Raven Bolle&Raven, thanks to the built-in mic and controls that work with both Apple and Android.
• Best for keeping a favorite pair alive → Adhiper Studio Pro Replacement. If the sound is still good and only the frame failed, this is the cheaper path than replacing the headphones.
• Model compatibility check → Bolle & Raven fits Beats Studio 2.0 only; Adhiper fits Beats Studio Pro only. Neither crosses over.
• Best if you're unsure what's wrong → neither, honestly. Diagnose first. A wireless adapter won't fix a snapped hinge, and a headband won't fix a dead connection.
In my opinion, the right pick comes down to one question: is your headphone broken, or just tethered? If it's working and you simply want Bluetooth, I'd buy the Bolle & Raven Bolle&Raven — it's a clean, purpose-built upgrade with a real battery, a mic and controls, and it targets exactly one model so there's no fudging on fit. If your Beats Studio Pro has a cracked headband or a failed hinge, I'd buy the Adhiper Studio Pro Replacement and repair what you already own. Two different jobs, two different answers. Match the product to your actual problem and you won't regret it.
what are the best wired studio headphones
There's no single best pair, and both products here are accessories rather than headphones themselves. Bolle & Raven Bolle&Raven actually removes the wire from a Beats Studio 2, while Adhiper Studio Pro Replacement keeps a Beats Studio Pro in service by replacing its headband and hinges. If you want to stay wired, you're shopping for headphones, not for either of these.
what are wired headphones
Wired headphones connect to your device with a physical cable rather than Bluetooth. The Beats Studio 2 is a wired headphone by default — which is exactly the problem Bolle & Raven Bolle&Raven solves by adding Bluetooth, a mic and up to 12 hours of playback and talk time.
what headphones do professional studios use
Studios tend to favor closed-back, wired models for reliable, low-latency monitoring. What matters for this comparison is that the Adhiper Studio Pro Replacement kit is built for the Beats Studio Pro, and Bolle & Raven Bolle&Raven is built for the Beats Studio 2.0 — check your model before buying either.
are all studio headphones wired
No. Plenty of studio-style headphones run wireless, and that's the whole point of Bolle & Raven Bolle&Raven, which converts a wired Beats Studio 2 into a Bluetooth headphone with on-board controls and a built-in mic. Just remember it's model-specific, so it only works with the Studio 2.0.
