If you want a complete pair of closed-back studio monitor headphones built for DJ applications, mobile listening, and sound isolation in noisy environments, choose POLSEN HPC-A30-MK2; if you need durable replacement shells and inner components to repair your existing Beats Studio 3 Wireless Over-Ear Headphones, choose Adhiper Studio3. These two items sit on opposite sides of the audio equipment spectrum: one is a fully functional audio device ready for music production and performance, while the other is strictly a repair kit designed to restore the physical integrity of a specific, already-obsolete model.
• POLSEN HPC-A30-MK2: Delivers rich, detailed sound with active sound isolation and swiveling earcups for one-ear monitoring; the trade-off is that it is a wired-only device requiring a cable connection rather than offering wireless freedom.
• Adhiper Studio3: Provides a cost-effective solution to replace cracked or damaged outer and inner shells for Beats Studio 3 owners without buying a new pair; the trade-off is that this product contains no electronics, drivers, or audio capabilities whatsoever—it is just plastic parts.
• Who it's for: The POLSEN pick is for DJs, podcasters, and producers needing a dedicated tool for critical listening, whereas the Adhiper option is exclusively for someone trying to save money by fixing an older, broken headphone unit.
The POLSEN HPC-A30-MK2 is engineered as a serious piece of gear for professionals and enthusiasts who need to hear exactly what is happening in their mix or performance, even when chaos surrounds them. Its over-ear circumaural design creates a seal around the ears, which isolates external noise effectively. This makes it an excellent choice for open ear headphones for music production scenarios where you need to block out a busy street or a loud club environment to focus on the low-end clarity. The tuned bass response ensures that the sub-frequencies are punchy and clear, a critical requirement when mixing tracks or monitoring live sets.
For those working in broadcast, podcasting, or vlogging, the ability to monitor audio on a laptop or smartphone simultaneously is a major advantage. The package includes a substantial 10-foot cable and a 1/4" adapter, giving you the reach needed to move around a home studio or connect to professional mixing consoles. The pivoting earcups add a layer of versatility that few consumer headphones offer; you can rotate one earcup outward for handheld one-ear monitoring or swivel it to rest on your shoulder during breaks. This flexibility is why these are often cited as the best sports earbuds for music production in terms of durability and situational awareness, though they are technically over-ear headphones.

However, you should skip this product if you require wireless connectivity. If you need the freedom of Bluetooth to run across a gym or dance floor without cables, this closed-back design will feel restrictive. Additionally, the build utilizes plastic materials, which might not feel as premium as metal alternatives, but it keeps the weight manageable at 10.2 ounces for long sessions. It is a workhorse designed for function, not luxury.
The Adhiper Studio3 is a very specific component sold for a single purpose: repairing the physical housing of the Beats Studio 3 Wireless Over-Ear Headphone. If you have a pair of Beats Studio 3 that has cracked shells, broken hinges, or dirty inner casings, this kit allows you to replace the gray plastic exterior and the internal structure without paying for a full unit replacement. The description highlights that the materials are high-quality soft plastic designed to fit perfectly, mimicking the original equipment manufacturer (OEM) feel. It is a straightforward solution for anyone who loves the sound signature of their Beats but cannot use them because the casing has failed.
This product is ideal for DIY enthusiasts who are comfortable with basic disassembly. The instructions note that installing the inner shell requires disconnecting the internal wiring routes, so some technical know-how is necessary. If you are not willing to take apart your headphones and reconnect delicate wires, this purchase will likely result in frustration rather than a fix. However, for those willing to do the work, it saves significant money compared to buying a brand-new pair of headphones or visiting a repair shop. The package includes both left and right shells along with the corresponding inner shells, ensuring a symmetrical restoration of your device.
You must understand that this item is not a standalone audio experience. It does not contain speakers, batteries, or microphones. It is purely a cosmetic and structural repair kit. If your goal is to find lightweight head phones for music production that you can wear immediately, this is not the answer. It is only for people who already own the specific Beats Studio 3 model and have suffered physical damage to its enclosure. The warranty offers protection against manufacturing defects in the plastic parts themselves, but it does not cover any accidental damage you might cause during the installation process.
• Best for actual audio playback → POLSEN HPC-A30-MK2 (It is a working headphone with drivers).
• Best for saving money on repairs → Adhiper Studio3 (It replaces expensive casing parts cheaply).
• Best for DJ monitoring → POLSEN HPC-A30-MK2 (Features swiveling cups and one-ear monitoring).
• Best for restoring old Beats → Adhiper Studio3 (Specifically compatible with Studio 3 models).
• Best for wired studio work → POLSEN HPC-A30-MK2 (Includes 10' cable and 1/4" adapter).
• Best for aesthetic restoration → Adhiper Studio3 (Replaces cracked gray plastic shells).
• Best for sound isolation → POLSEN HPC-A30-MK2 (Over-ear design blocks ambient noise).

In my opinion, if your primary goal is music production or general listening, the POLSEN HPC-A30-MK2 is the only logical choice here. It is a complete, functional tool designed to deliver accurate audio with a tuned bass response and excellent isolation for noisy environments. The Adhiper Studio3, while useful for a niche repair scenario, is merely a bucket of plastic parts that cannot produce a single note on its own. Unless you are currently holding a broken Beats Studio 3 and looking to extend its life, the POLSEN offers real value as a standalone device for serious listening.
No, the POLSEN HPC-A30-MK2 uses wired connectivity with a 3.5 mm jack and includes a 10-foot cable, while the Adhiper product is just a replacement shell for a wireless headphone and does not contain any electronics itself.
No, the Adhiper Studio3 kit only replaces the outer and inner plastic shells; it does not change the drivers, battery, or internal circuitry, so your audio quality remains exactly the same as before the repair.
The product data sheet lists the included items as the headphones, a 10-foot cable, and a 1/4" TRS adapter, but it does not mention a carrying case or protective pouch in the packaging contents.
