If you want a wireless over-ear headphone with a huge 72-hour battery rating and a wired option for studio-style listening, choose OneOdio Over Ear Headphones; if you need a two-pack of hard travel cases to protect folding headphones you already own, choose DR·AMIU 2.
• OneOdio Over Ear Headphones — biggest strength: A genuine audio product with 40mm dynamic neodymium drivers, a 20Hz–20kHz frequency range, Hi-Res tuning from a professional audio team, and a 72-hour battery rating. It works both wired (3.5mm jack) and wireless (Bluetooth).
• OneOdio Over Ear Headphones — biggest trade-off: It is an actual headphone, not an accessory, so it solves a listening problem — not a storage problem. The 220g weight and over-ear fit are worth considering if you want something feather-light.
• DR·AMIU 2 — biggest strength: Two hard EVA-shell cases in one pack, oxford cloth on the outside and a mesh pocket inside for cables and small accessories. They're built for folding headphones from brands like Beats, JBL, Skullcandy and Soundcore.
• DR·AMIU 2 — biggest trade-off: It contains no headphones at all. If you don't already own a foldable pair, this purchase makes no sense on its own.
• Who each pick is for: OneOdio for someone who wants one do-everything wireless headphone for laptop, PC, tablet and casual studio use. DR·AMIU 2 for someone who already has folding headphones and wants to stop throwing them loose into a bag.
The OneOdio A70 is, first and foremost, a listening device. Its spec sheet reads like a proper headphone rather than a lifestyle gadget: 40mm neodymium dynamic drivers, a frequency range of 20Hz to 20kHz, 32-ohm impedance, and a custom aluminum fascia. That combination — big drivers, low-ish impedance, wide frequency range — is the classic recipe for punchy bass and an energetic stereo image that doesn't need a headphone amp to sound alive. The "Hi-Res" claim comes from OneOdio's in-house audio team, and while I treat any brand's own tuning language with a healthy dose of skepticism, the hardware underneath is legitimate.
The 72-hour battery figure is the headline number. OneOdio lists 72 hours for both charge time and average life, which is unusual phrasing, but the intent is clear: this is a long-endurance headphone. Even accounting for real-world variance, that's the kind of rating that means charging once every week or two rather than every night. Controls are touch-based for media, and noise control is handled through sound isolation — passive blocking from the over-ear cup seal, not active noise cancellation. So don't expect to silence a jet engine; do expect a decent seal that tames office chatter and keyboard clatter.
Who should buy it: Anyone who wants one headphone for the desk and the commute — laptop, PC, tablet, phone — and values long battery life plus the safety net of a wired connection. The gold finish is a look, so buy it if you like a bit of flash.
Who should skip it: If you need true active noise cancellation for flights, this isn't that product. If you want the lightest possible headphone, 220g is moderate, not ultralight. And if your actual problem is a cracked headband or a crushed earcup in your backpack, buying a headphone won't fix it — you want a case.
DR·AMIU 2: Who It's For
The DR·AMIU 2 is a completely different animal, and it's important to be honest about that: this is not a headphone. It's a two-pack of hard carrying cases built for folding headphones. The description is explicit — only the travel carrying case is included, headphones are not. If you're comparing these two products expecting two sets of headphones, stop here and re-read the listing.
Judged as what it is, though, it's a sensible product. The case uses a three-layer construction: oxford cloth on the surface, hard EVA material in the middle, and a soft interior. That's a real protective sandwich, and it's aimed at the things that actually kill headphones — scratches, dust, splashes and impacts. EVA is the same family of material used in a lot of molded gear cases, and it holds a shape well while staying light. The zipper is described as strong, which is the part that fails first on cheap cases, so that's the right thing to emphasize.
Inside, there's a mesh pocket for a charging cable and small accessories. That's a small detail that makes a real difference in daily use, because the cable is usually the thing that goes missing or gets tangled around everything else in your bag. The case is sized for folding headphones specifically — the listing names Beats, JBL, Skullcandy, Soundcore, Picun, BERIBES, TOZO and KVIDIO among compatible brands. Note the word "folding." A headphone that doesn't fold may not sit snugly, so check your model's fold before buying.
The two-pack is the interesting part of the value equation. One case lives in your travel backpack, one stays home or goes in a desk drawer. Or you split them with a family member. For anyone who owns multiple folding headphones — or who has already ruined one pair by tossing it loose into a bag — that's a practical, low-drama purchase.
Who should buy it: Owners of folding over-ear headphones from the brands listed, frequent travelers, students hauling gear between classes, and anyone who wants a spare case on hand.
Who should skip it: Anyone who doesn't already own foldable headphones. Anyone whose headphones don't fold. And anyone shopping for sound — this product makes no sound at all.
• Best for actually listening to music → OneOdio Over Ear Headphones. It's the only one of the two that produces audio.
• Best for battery life → OneOdio Over Ear Headphones. The 72-hour rating is the standout figure on either sheet.
• Best for wired plus wireless flexibility → OneOdio Over Ear Headphones. Bluetooth and a 3.5mm jack with a 1.2m cable covers desk and mobile use.
• Best for studio-style monitoring and mixing → OneOdio Over Ear Headphones. 40mm dynamic drivers, 32-ohm impedance and a 20Hz–20kHz range fit that role.
• Best for protecting headphones you already own → DR·AMIU 2. Hard EVA shell, oxford cloth exterior, mesh accessory pocket.
• Best for travelers and commuters with folding cans → DR·AMIU 2. Lightweight, compact, sized to slip into a backpack.
• Best for getting two units instead of one → DR·AMIU 2. It ships as a two-pack of cases.
• Best for a single all-round purchase → OneOdio Over Ear Headphones, in my opinion, because it does a job on its own rather than supporting something else.
My Verdict
No. It's a two-pack of hard carrying cases for folding headphones. The listing states clearly that headphones are not included. It only helps if you already own a foldable pair.
Not active noise cancelling. The spec sheet lists sound isolation, which means passive blocking from the over-ear cup seal. That reduces background noise but won't erase engine drone the way ANC does.
OneOdio rates it at 72 hours of average battery life. Treat that as the manufacturer's figure rather than a guaranteed result — real-world numbers vary with volume and connection type.
Then the DR·AMIU 2 is the logical add-on, especially if your current pair travels loose in a bag. If you want a second, wireless-capable headphone for desk and mobile use, OneOdio is the better fit.
