If you want to refresh and extend the life of a pair of beyerdynamic DT 700 PRO X headphones you already own, choose beyerdynamic EDT 700; if you need a complete open-back studio headphone for mixing, mastering or tracking, choose OneOdio Monitor 80.
• beyerdynamic EDT 700 — biggest strength: a genuine beyerdynamic replacement ear pad set built specifically for the DT 700 PRO X, with soft memory foam and breathable velour.
• beyerdynamic EDT 700 — biggest trade-off: it is not a headphone. It is a spare part, so it only makes sense if you already own the DT 700 PRO X.
• OneOdio Monitor 80 — biggest strength: a complete open-back studio headphone aimed at mastering, mixing and tracking, with Hi-Res audio certification and a USB-C to 3.5 mm adapter in the box.
• OneOdio Monitor 80 — biggest trade-off: open-back designs leak sound and isolate poorly, so they are a poor fit for noisy rooms or commuting.
• Who the EDT 700 is for: existing DT 700 PRO X owners whose pads are worn and who want to restore comfort and airflow.
• Who the Monitor 80 is for: producers, engineers and home-studio users who need an open, spacious monitoring headphone and a wired USB-C option.
The EDT 700 is a replacement ear pad set, not a listening device. That single fact decides everything about who should buy it. It is made by beyerdynamic for the beyerdynamic DT 700 PRO X, in a grey velour finish, and the package includes two fleece pads plus a clamping ring. The pads use soft memory foam, and the velour surface is designed to stay supple while letting air circulate around your ears.
If you already own the DT 700 PRO X and the original pads have flattened, hardened or started flaking, this is the direct, brand-matched fix. Velour plus memory foam is a combination aimed squarely at long sessions — the kind of comfort you want when you are tracking for hours and do not want heat building up against your head. The air circulation point matters more than it sounds: closed-back headphones trap warmth, and a breathable pad material is one of the few things that genuinely reduces that.
Installation is a DIY job. beyerdynamic states the pads go on without additional tools, and the clamping ring is included to help you seat them. You do not need to send the headphone anywhere or pay for service — you swap the pads yourself.
OneOdio Monitor 80: Who It's For
The OneOdio Monitor 80 is the opposite kind of purchase: a complete headphone rather than a component. It is an open-back studio model, Hi-Res audio certified, and OneOdio positions it as a companion for mastering, mixing or tracking. The kit also includes a USB-C to 3.5 mm adapter, which is a small detail that solves a very modern problem — phones and laptops that have dropped the headphone jack.
The open-back design is the defining feature. Open-back headphones let air move behind the driver, which typically produces a wider, more natural sense of space than a closed cup. That is why they show up in mixing and mastering work: you hear more of the room and less of the cup. The trade-off is equally real. Open-back headphones leak audio outward and let outside noise in, so they are a bad choice for a noisy home, a shared office or public transport.
Who should buy it? Someone building a home studio who wants an open, airy monitoring headphone for critical listening, and who works in a reasonably quiet space. The included USB-C adapter also makes it flexible for laptop-based producers who may not have a 3.5 mm output free.
Who should skip it? Anyone who needs isolation — drummers tracking with loud click bleed, commuters, or people in a busy household. And anyone who already owns a good open-back pair and is only looking to replace worn parts, because this is not a spare-part product.
• Best for repairing an existing headphone → beyerdynamic EDT 700. It is a purpose-built replacement set for the DT 700 PRO X.
• Best for a complete listening solution → OneOdio Monitor 80. It is a finished headphone with a cable adapter included.
• Best for long, warm sessions → beyerdynamic EDT 700. Velour and memory foam are chosen for airflow and sustained comfort.
• Best for mixing and mastering → OneOdio Monitor 80. The open-back design and Hi-Res certification point at studio reference work.
• Best for noisy environments → beyerdynamic EDT 700 (indirectly). The pads suit a closed-back headphone; the Monitor 80's open-back build leaks sound both ways.
• Best for modern laptops and phones → OneOdio Monitor 80. The bundled USB-C to 3.5 mm adapter covers devices without a headphone jack.
• Best for low-effort ownership → OneOdio Monitor 80. No assembly decisions, no compatibility check — you plug in and listen.
• Best if you already love your DT 700 PRO X → beyerdynamic EDT 700. New foam and fresh velour can make an old favourite feel new again.
In my opinion, these two products do not really compete — they solve different problems, and the right answer depends on what is already on your desk. If you own a DT 700 PRO X and the pads are tired, I would buy the beyerdynamic EDT 700. It is the brand's own part, it installs without tools, and velour over memory foam is exactly what that headphone was designed around.
If you are starting from nothing and want an open-back studio headphone for mixing, I would buy the OneOdio Monitor 80 instead — it is a complete product with the adapter included. Just be honest about your room: if it is loud, open-back is the wrong tool.
Is the beyerdynamic EDT 700 a pair of headphones?
No. It is a replacement ear pad set for the beyerdynamic DT 700 PRO X. The box contains two fleece pads and one clamping ring, and it is designed to be fitted by the owner without extra tools.
Yes — OneOdio includes a USB-C to 3.5 mm adapter with the Monitor 80, which covers USB-C devices that lack a 3.5 mm output.
They are not interchangeable, so compare by need rather than by price. Buy the EDT 700 to restore an existing DT 700 PRO X; buy the Monitor 80 if you need a complete open-back studio headphone. Check the current price on Amazon for whichever one matches your situation before deciding.
