How to Store and Protect Open-Back Planar Headphones: Abyss Diana MRx and Beyond

Quick answer

Store open-back planar headphones on a padded stand or in a hard case, away from humidity and direct sunlight. Always handle them by the headband, keep the drivers free of debris, and use a desiccant in humid environments. For travel, a hard case with custom foam is the safest option.

Open-back planar headphones like the Abyss Diana MRx are precision instruments, with thin diaphragms and powerful magnets that need careful handling. Their open-back design lets air flow through, making them more exposed to dust, moisture, and accidental damage than closed-back models. Proper storage is not just about keeping them clean—it's about preserving the sound quality and longevity of the drivers.

In this guide, we'll walk you through the best practices for storing and protecting open-back planar headphones, from daily placement to long-term storage and travel. Whether you're a seasoned audiophile or new to planar magnetic technology, these steps will keep your investment safe and sounding its best.

Understand the fragile nature of planar drivers

Planar magnetic headphones use a thin, flat diaphragm suspended between magnets. This design offers exceptional detail and low distortion, but it also means the diaphragm is more sensitive to physical shock and high air pressure. A sudden drop or a hard knock can warp the diaphragm or cause it to hit the magnets, leading to audible distortion or even permanent damage.

Because of this, you should always handle your headphones by the headband, not the ear cups. When setting them down, place them gently on a soft surface. Avoid letting the ear cups slam together, and never apply direct pressure to the driver area. Even the act of putting them on should be done with care—use both hands to stretch the headband slightly, rather than forcing the cups over your ears.

• Always grip the headband, not the ear cups, when picking up or adjusting your headphones.

Choose the right resting place: stand vs. case

When you're not using your open-back planars, you have a choice: rest them on a stand or keep them in a case. A padded headphone stand is great for frequent use because it keeps the headphones accessible and lets them air out. However, a stand leaves them exposed to dust, spilled drinks, and curious pets. If you choose a stand, opt for one with a wide, non-slip base and a cushion that won't compress the headband permanently. Over time, a too-tight or hard stand can put stress on the headband and alter its clamping force.

A hard case offers the best protection, especially if you have multiple headphones or live in a dusty or high-traffic home. Cases with custom-cut foam prevent the ear cups from pressing against each other and absorb shocks from accidental drops. If you don't have a custom case, a generic hard case with soft padding works, provided the headphones fit snugly without forcing them into a shape. For daily use, consider a semi-hard pouch inside a drawer or shelf, but for long-term storage, a hard case is the safest bet.

• If using a stand, check the headband cushion for signs of compression every few months.

Manage humidity and temperature

Planar drivers are sensitive to extreme humidity and temperature changes. High humidity can cause corrosion on the magnetic traces and degrade the adhesive bond between the diaphragm and its support. Low humidity can cause static buildup, which attracts dust and may lead to discharge that damages the driver. The ideal environment is a cool, dry room with relative humidity between 40-60%.

If you live in a humid climate, place a silica gel desiccant pack in your headphone case, but make sure it doesn't touch the headphones directly. Avoid storing headphones in attics, basements, or near radiators. Also, let your headphones acclimate to room temperature after moving them between hot and cold environments, like from a car to a warm house, to prevent condensation from forming inside the driver housing.

• Consider a hygrometer in your listening room to monitor humidity levels.

Protect the drivers from dust and debris

The open-back design means dust, hair, and other small particles can enter the driver cavity and settle on the diaphragm. Over time, this can affect sound quality, creating tiny vibrations or rattles. To minimize this, always cover your headphones when not in use, either by storing them in a case or draping a microfiber cloth over them. But be sure the fabric is clean and lint-free, as loose fibers can make their way in.

When cleaning, never use canned air directly on the driver—it can blow debris deeper in or even damage the diaphragm. Instead, use a soft, dry brush with gentle strokes to remove surface dust from the ear pads and grille. For deeper cleaning, consult your headphone manual or a professional. If you notice a persistent rattle or dirty driver, it's safer to have it serviced than to risk disassembly yourself.

• Use a soft, dry brush or a microfiber cloth for surface cleaning; avoid vacuuming near the drivers.

Travel safely with a hard case

Traveling with open-back planar headphones requires extra caution. The thin diaphragm is vulnerable to pressure changes and impact. When flying, never check them in your luggage; always carry them on board. A hard case that fits under the seat is ideal, and it should have enough padding to prevent movement. If your case doesn't have custom foam, wrap the headphones in a soft cloth and position them so the ear cups face outward, not pressing against the case walls.

Also, be mindful of the headband yoke and any detachable cables. Use the included cable (if any) or a quality replacement cable, and coil it neatly away from the ear cups. This reduces stress on the connectors and prevents localized pressure. If your headphones have a removable cable, disconnect it before packing to avoid bent pins.

• For short trips, a hard-sided case with a handle is more protective than a soft pouch.

Consider upgrade cables and accessories

While not directly related to storage, having the right cables and accessories can indirectly protect your headphones. A quality cable with a secure, strain-relieved connector reduces the risk of accidental yanks that could cause the headphones to fall. When you're not using them, unplug the cable from the headphones and store it separately to avoid stress on the input jacks.

If you're using a balanced connection, ensure the cable mate is clean and free of corrosion. A small amount of contact cleaner on a cotton swab can keep the terminals in good shape. For headphones like the Abyss Diana MRx, which may have a proprietary connector, invest in a backup cable if you travel often, so a damaged cable doesn't leave you without music.

• Check cable connectors for signs of wear or corrosion before each use.

Step-by-Step Storage and Protection Routine

1. Choose a safe resting place: Decide between a padded stand for daily access or a hard case for maximum protection. Make sure the stand doesn't indent the headband and the case has a snug but not tight fit. A case is better if you have pets, kids, or a dusty room.
2. Control the environment: Keep your headphones at room temperature and maintain relative humidity between 40-60% using a hygrometer and desiccant packs if needed. Avoid attics, basements, and window sills to prevent temperature swings and moisture damage.
3. Keep drivers dust-free: Cover the headphones with a clean cloth or store them in a case when not in use. Clean surface dust with a soft brush or microfiber cloth, never canned air. If you hear a persistent rattle, have a professional service your drivers.
4. Pack safely for travel: Use a hard case, carry them on if flying, and disconnect any detachable cables before packing. Add desiccant if traveling in humid climates. Your headphones should be the first thing you pack and the last thing you unpack.
