If you want closed-back isolation for tracking and critical listening in noisy rooms, choose beyerdynamic Box; if you need an open-back headphone-and-monitor bundle that lets you hear your room while you mix, choose Audiosavings Presonus Eris Studio.
• beyerdynamic Box — biggest strength: A closed-back, over-ear reference headphone with 250-ohm drivers and an enormous 5 Hz–35 kHz frequency range, built for accurate, isolated monitoring.
• beyerdynamic Box — biggest trade-off: At 250 ohms it wants a real headphone amplifier, and the closed-back design means no natural room bleed — you're sealed in.
• Audiosavings Presonus Eris Studio — biggest strength: A three-piece bundle pairing open-back AKG K701 reference headphones with a pair of Presonus Eris Studio 8 powered monitors, so you get both a headphone path and a speaker path.
• Audiosavings Presonus Eris Studio — biggest trade-off: Open-back headphones leak sound both ways, and the bundle commits you to a full monitoring setup rather than one piece of gear.
• Pick beyerdynamic Box if you record, track, or mix in a space where you need isolation and one dependable closed-back headphone.
• Pick Audiosavings Presonus Eris Studio if you want open-back listening plus a stereo monitor pair for a home or project studio.
The beyerdynamic Box is a closed-back, over-ear studio headphone built around 250-ohm dynamic drivers. That impedance figure matters more than most specs on the page. 250 ohms is high for a headphone, which is exactly why the design notes call it ideal for home stereos and studio equipment — it's meant to be driven by a headphone amplifier or a proper interface output, not by a phone dongle. Pair it with real amplification and you get the payoff: a frequency range of 5 Hz to 35,000 Hz, which is a genuinely wide window for a dynamic driver.
The closed-back enclosure is the defining choice here. Fabric earcups seal around your ears, so sound stays in and the outside world stays out. For tracking a vocalist while a backing track plays, or for mixing in a room with a fan, a fridge hum, or a roommate, that isolation is the whole point. The description leans on the low-mass coil and diaphragm assembly as the reason the sound stays clean and detailed, and on the build quality that has kept this model in studios for a long time.
Who should buy it: anyone who records, edits, or mixes in a less-than-silent space, and anyone who wants one closed-back reference headphone they can rely on for years. The cushioned packaging with cable management, the 3.5 mm jack plus 1/4-inch adapter, and the touch-based control set round out a practical, wired tool.
Audiosavings Presonus Eris Studio: Who It's For
This bundle is three items, not one, and that changes the entire question. You get a pair of Presonus Eris Studio 8 powered monitors and one AKG K701 open-back reference headphone. The K701 is the open-back piece the comparison angle hinges on: an over-ear, open design with 62-ohm impedance, 105 dB SPL/V sensitivity, a 10 Hz–39,800 Hz bandwidth, and a light 235 g net weight. Low impedance plus high sensitivity means it's far easier to drive than a 250-ohm headphone — it plays loud off modest gear.
Open-back means the rear of the driver is vented. You hear the room, the room hears you, and the soundstage tends to feel wider and less boxed-in. For long mixing sessions and hi-fi listening, that's the appeal, and the data sheet lists exactly those two applications: studio mixing and hi-fi listening. The trade-off is leakage — not the tool for tracking a live mic nearby or for blocking out a noisy household.
The Eris Studio 8 monitors carry the rest of the bundle. Each has an 8-inch woven composite low-frequency driver and a 1.25-inch silk-dome tweeter behind an EBM waveguide covering 100° horizontal by 60° vertical, with a front-firing acoustic port so you can place them closer to a wall. Power is 140W Class AB bi-amplification, response runs 35 Hz to 20 kHz, and peak output is rated 105 dB SPL at one meter. On the back you get balanced XLR and 1/4-inch inputs plus unbalanced RCA, and real tuning controls: high frequency ±6 dB, midrange ±6 dB, acoustic space in flat/-2/-4 dB, and a highpass filter at off/80 Hz/100 Hz. There's also protection circuitry for RF interference, over-current, over-temperature, transients, subsonics, and soft start.
Who should buy it: someone building a home or project studio who wants both a speaker path and an open-back headphone path in one purchase, and who has the desk space and acoustic freedom for monitors. Who should skip it: anyone who only needs a single isolated headphone, or who can't use speakers where they work.
• Best for isolation and tracking → beyerdynamic Box. The closed-back fabric enclosure seals sound in and out, which open-back designs can't do.
• Best for open-back, wide soundstage listening → Audiosavings Presonus Eris Studio. The AKG K701 is explicitly an open, over-ear reference headphone for mixing and hi-fi.
• Best for easy driveability → Audiosavings Presonus Eris Studio. At 62 ohms and 105 dB SPL/V, the K701 is far less demanding than the 250-ohm beyerdynamic.
• Best for a proper amplified setup → beyerdynamic Box. 250 ohms is designed for home stereos, interfaces, and studio equipment, where it rewards real amplification.
• Best for mixing on speakers as well as headphones → Audiosavings Presonus Eris Studio. You get two 8-inch powered monitors with XLR, 1/4-inch, and RCA inputs plus acoustic tuning controls.
• Best for wide frequency coverage → a near tie, slight edge to Audiosavings Presonus Eris Studio. The K701 spans 10 Hz–39,800 Hz; the beyerdynamic spans 5 Hz–35,000 Hz. Different shapes, both extremely wide.
• Best for room-correction flexibility → Audiosavings Presonus Eris Studio. HF, midrange, acoustic space, and highpass controls let you tune the monitors to the space.
• Best for one durable, single-purpose tool → beyerdynamic Box. One headphone, wired, with a 3.5 mm jack and 1/4-inch adapter, and a long-standing reputation for build quality.
If I had to pick one, I'd go with Audiosavings Presonus Eris Studio — but only because of what it is as a package. In my opinion, the bundle gives you more paths to work with: an open-back K701 for mixing and relaxed listening, plus a pair of 8-inch powered monitors with genuine tuning controls for the room. That's a studio starter kit in one box. I'd choose beyerdynamic Box instead if your priority is a single isolated closed-back headphone for tracking and noisy environments — its 250-ohm design and sealed enclosure do a job the open-back K701 simply can't. Match the pick to your room, not to the spec sheet.
how to open back headphones work
Open-back headphones leave the rear of each driver vented rather than sealed. That lets air move freely behind the driver, so you hear more of the room and the sound tends to feel wider — which is exactly how the AKG K701 in this bundle is built, with an open, over-ear design rated 62 ohms and 105 dB SPL/V.
what is open back studio headphones
They're reference headphones with a vented, unsealed rear cup, intended for mixing and critical listening rather than isolation. The K701 here is listed for studio mixing and hi-fi listening, weighs 235 g, and covers 10 Hz–39,800 Hz — but it leaks sound in both directions.
what are the best open back headphones
I won't crown a universal winner, because "best" depends on your amp and your room. In my opinion, the K701 in this bundle is a strong open-back pick for mixing and hi-fi, while the beyerdynamic Box is the better choice if you actually need a sealed, closed-back headphone instead.
are open back headphones better
Not universally — they're better for spacious, natural listening and long mixing sessions, and worse for isolation. Closed-back designs like the beyerdynamic Box keep sound in and noise out, which is why they suit tracking. Open-back like the K701 suits mixing where you want to hear the room.
