If you want a crush-resistant hard shell to carry and protect a pair of Beyerdynamic DT 770/880/990 PRO studio headphones, choose Aenllosi Hard Carrying Case; if you need a replacement headband and hinge set to repair a broken Studio Pro 2023 wireless headphone, choose HQB-STAR Studio Pro 2023.
• Aenllosi's biggest strength: a molded EVA hard shell (grey) that's crush resistant, anti-shock and water resistant, with an internal mesh pocket for small accessories.
• Aenllosi's biggest trade-off: it's storage only — the case protects your headphones, it doesn't fix or replace any part of them, and the headphones themselves aren't included.
• HQB-STAR's biggest strength: a full repair kit — one headband, a pair of hinges, a screwdriver and eight screws, sized at 9.05 x 1.06 inches to match the original Studio Pro 2023 parts.
• HQB-STAR's biggest trade-off: it's plastic replacement hardware, not a protective case, and it only fits Studio Pro 2023 headphones — not Beyerdynamic models.
• Pick Aenllosi if your headphones work fine and you want to keep them that way on the move.
• Pick HQB-STAR if your Studio Pro 2023 headband or hinge is cracked, snapped or worn out and you want to rebuild it instead of replacing the whole headphone.
The Aenllosi case is a purpose-built home for Beyerdynamic DT 770, DT 880 and DT 990 PRO headphones in the 32, 80 and 250 Ohm versions. That compatibility list is the whole point: this isn't a generic pouch that "sort of" fits. It's shaped around that family of over-ear studio headphones, and the grey EVA shell is the reason it exists. EVA is the same foamed material used in a lot of semi-rigid gear cases, and Aenllosi leans on it here for three specific jobs — resisting crushing, absorbing bumps and shocks, and shrugging off splashes.
In everyday terms, that means the case is built for the person who moves their headphones around. Tossing a pair of DT 770s loose into a backpack next to a laptop, a water bottle and a tangle of cables is how headbands get twisted and earcups get scratched. A hard shell with a water-resistant exterior removes most of that risk. The internal mesh pocket is a small but genuinely useful detail: it gives you somewhere to put a spare cable, a 3.5 mm-to-6.35 mm adapter or an extra pair of earpads so they're not rattling around loose against the drivers.
Who should skip it? If your headphones are broken, this won't help — it's a case only, and the device and accessories are not included. If you own a different brand or a non-PRO model that isn't on the compatibility list, don't assume it fits. And if your headphones never leave your desk, a hard travel shell is solving a problem you don't have.
HQB-STAR Studio Pro 2023: Who It's For
The HQB-STAR kit is a completely different kind of product, and it's worth being clear about that up front. This is a replacement headband and hinge set for the Studio Pro 2023 wireless Bluetooth over-ear headphone. It's repair hardware, not protection. The headband measures 9.05 x 1.06 inches (23 x 2.7 cm), and HQB-STAR states it matches the original Studio Pro 2023 parts in both color and size, so once it's installed it's designed to blend in as if nothing was ever swapped.
The package is what makes this practical rather than frustrating: one headband, a pair of hinges, one screwdriver and eight screws. That's the difference between "a part arrived" and "I can actually do this job today." If you've ever ordered a replacement piece and then realized you don't own the right driver or the original screws are stripped, you know why the included tooling matters. The hinges are the other half of the story — on a lot of folding over-ear headphones, the hinge is the first thing to go, and a headband replacement without matching hinges would only fix half the problem.
Who should buy it? Someone whose Studio Pro 2023 headphones still sound fine but have a cracked headband, a snapped hinge or a joint that's gone floppy from years of folding and unfolding. If the electronics work and the plastic frame is the failure point, this kit is aimed squarely at you. It's also for the person who'd rather spend an afternoon with a screwdriver than send a functional pair of headphones to landfill.
Who should skip it? Anyone hoping to protect their headphones from damage in the first place — this does nothing for that. Anyone who owns a different headphone model, because the fit is specific to the Studio Pro 2023. And anyone who isn't comfortable with basic disassembly: the kit gives you the parts and the screwdriver, but it doesn't install itself.
Side-by-Side: Which Should You Choose?
• Best for fixing broken headphones → HQB-STAR Studio Pro 2023. Headband, hinges, screwdriver and eight screws in one box.
• Best for travel and commuting → Aenllosi. A 200 g hard case with a mesh pocket for cables and adapters.
• Best for a DIY repair afternoon → HQB-STAR. Everything you need to swap the headband and hinges is included.
• Best for Beyerdynamic DT 770/880/990 PRO owners → Aenllosi. That's exactly the compatibility list.
• Best for Studio Pro 2023 owners → HQB-STAR. The parts are sized and matched to that specific headphone.
• Best for storage at home → Aenllosi. A defined, padded spot beats a drawer full of loose gear.
• Best for extending the life of an existing pair → HQB-STAR. It rebuilds the frame instead of replacing the whole unit.
These two products barely compete — they solve opposite problems, and the right answer depends entirely on whether your headphones are intact or broken. If I had to pick one for the most people, I'd take the Aenllosi Hard Carrying Case. Most headphone owners have a working pair and a bad storage habit, and a crush-resistant, water-resistant EVA shell fixes that every single day rather than once. That said, if your Studio Pro 2023 has a cracked headband or a failed hinge, no case on earth will help you — the HQB-STAR repair kit is the only one of the two that puts a working headphone back on your head. In my opinion, buy the case to prevent the problem, and buy the kit only when the problem has already happened.
They do different jobs. Aenllosi is a hard EVA carrying case that protects Beyerdynamic DT 770/880/990 PRO headphones. HQB-STAR is a replacement headband and hinge kit for Studio Pro 2023 headphones. One protects, the other repairs.
Yes — the case is listed as compatible with the DT 770, DT 880 and DT 990 PRO in 32, 80 and 250 Ohm versions. It's a replacement case only, so the headphones and accessories are not included.
No. It's built specifically for the Studio Pro 2023 wireless Bluetooth over-ear headphone, with the headband sized at 9.05 x 1.06 inches to match the original. Don't expect it to fit other brands.
