How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a tough, travel-ready hard case that keeps a pair of folding headphones protected in a backpack or gym bag, choose DR·AMIU 2; if you need wired over-ear headphones built for studio monitoring, mixing and instrument work, choose syndesmos Headphones. That is the entire comparison in one line, and it matters most for running, because these two products solve two completely different problems for the same person: DR·AMIU 2 protects the gear you already own, while syndesmos Headphones is the gear itself.
• DR·AMIU 2 — biggest strength: a two-pack of hard EVA cases with a molded interior that fits folding headphones from Beats, JBL, Skullcandy, Soundcore, Picun and similar brands, plus a mesh pocket for cables. It is protection you can toss in a bag without thinking about it.
• DR·AMIU 2 — biggest trade-off: it is not audio gear at all. There are no drivers, no battery, no Bluetooth. If you want to hear something, this product does nothing for you.
• syndesmos Headphones — biggest strength: a wired over-ear design with 50mm dynamic drivers, a 20Hz–20kHz range, 32-ohm impedance, 90° swiveling ear cups for single-side monitoring, and both 3.5mm and 6.35mm detachable plugs — no adapter hunting.
• syndesmos Headphones — biggest trade-off: it is wired only, so there is no multipoint pairing, no wireless freedom, and nothing "sporty" about the design. It is a studio tool, not a running companion.
• Who each pick is for: DR·AMIU 2 is for the person who already owns folding headphones and wants them to survive daily life. syndesmos Headphones is for the person recording, mixing, DJing or monitoring who needs a reliable wired connection.
DR·AMIU 2 does one job and does it with a specific kind of care. Each case is built in three layers: an oxford cloth surface, a hard EVA middle shell, and a soft interior. That combination is what stands between your headphones and the scratches, dust, splashes and impacts that come with living in a backpack. The molded interior is sized for folding headsets, so the earcups sit snugly instead of sliding around, and the mesh pocket holds the charging cable and small accessories so they do not end up loose at the bottom of your bag.
In my opinion, you should buy DR·AMIU 2 if you already own folding headphones from one of the compatible brands and you are tired of replacing them. It is also a sensible pick if you carry two headsets — one for workouts, one for everything else — and want both protected. You should skip it if you are shopping for sound. There is no audio here, no battery, no wireless anything. The listing is explicit that only the carrying case is included, not headphones, so if you were hoping for a two-for-one, this is not that.
syndesmos Headphones: Who It's For
syndesmos Headphones is a wired over-ear monitor built around a 50mm dynamic driver. That large driver size, paired with a 20Hz–20kHz frequency range and 32-ohm impedance, is the classic recipe for a headphone that can run straight off a phone or laptop without a dedicated amp while still handling a mixer or interface. The tuning is described as dynamic bass, balanced mids and precise treble — a profile aimed at people who need to hear what is actually in a track rather than a heavily colored version of it.
The practical details are where this headphone earns its place. The ear cups swivel 90 degrees so you can slide one off for single-ear monitoring while tracking. The headband is self-adjustable and flexible, and the whole thing weighs 260g with memory cotton cushions and protein-leather padding, which is the difference between a session that lasts hours and one that ends early. It folds too, which matters if you are moving between a desk, a booth and a stage.
Then there is the cable. A 5.7–6 ft coiled cord reaches from a TV or stereo to your chair, and both the 6.35mm and 3.5mm plugs are detachable, so you can switch between a mixer and a phone without an adapter. There is also a sharing feature: plug the 6.35mm jack into the main headphones and a 3.5mm jack into a second pair, and two people can listen at once. You should buy syndesmos Headphones if you record, mix, DJ, play guitar through an amp, or work on a keyboard and computer setup. You should skip it if you want wireless freedom or a headphone for running — a wired coiled cable is not what you want on a treadmill.
• Best for protecting folding headphones → DR·AMIU 2. Hard EVA shell, molded fit, mesh accessory pocket, two cases in the box.
• Best for actual listening → syndesmos Headphones. 50mm drivers, 20Hz–20kHz, 32 ohm.
• Best for recording and mixing → syndesmos Headphones. 90° swiveling cups for single-ear monitoring and a flat-leaning studio tuning.
• Best for connecting to a mixer without adapters → syndesmos Headphones. Detachable 6.35mm and 3.5mm plugs and a coiled 5.7–6 ft cord.
• Best for two people listening together → syndesmos Headphones. The 6.35mm-to-3.5mm sharing setup lets a second pair join in.
• Best for travel and bag life → DR·AMIU 2. Lightweight, compact, quick zipper, built to take impacts so your headphones do not.
• Best for long sessions → syndesmos Headphones. 260g, memory cotton, protein leather, foldable headband.
• Best if you want wireless, multipoint, spatial audio or long battery life in-ear earbuds → neither. DR·AMIU 2 has no electronics and syndesmos Headphones is wired, so if those features are your priority you are looking at the wrong two products.
If I had to pick one, I would buy syndesmos Headphones, because it is the product that actually does something — it produces sound, and it does so with a spec sheet that holds up for studio and instrument work. DR·AMIU 2 is a genuinely good accessory, and I recommend it without hesitation if your goal is keeping a folding headset alive through commutes and trips. But it is a case, not a headphone, and no amount of protection substitutes for a driver. For running specifically, I would skip both and look elsewhere: a wired coiled cable and a hard case are the wrong tools for a workout, and neither product is designed around movement.
FAQ
No adapter required. The headphone ships with both a 6.35mm and a 3.5mm plug, and both are detachable, so you can move between a mixer, an interface, a phone, a tablet or a computer directly.
Neither is built for it. syndesmos Headphones is wired with a coiled cord, which is awkward in motion, and DR·AMIU 2 is a storage case. If you want multipoint Bluetooth or long battery life in-ear earbuds for running, that is a different category of product.
