Carrying Case Compatible with Sennheiser HD 650 HD 660S HD 600

In this review the SPARTAN carrying case is evaluated as a travel and home storage solution for owners of multiple Sennheiser models. The bottom line: it is aimed at listeners who want reliable physical protection and tidy storage for high-end open-back headphones, and the single biggest reason to buy is its hardened EVA shell combined with a plush interior that keeps headphones safe from crushing and abrasion. The review focuses on build, fit, and practical features rather than promotional claims.

Key Features

• Great Compatibility: The case is sized and shaped to accommodate HD 650, HD 660S, HD 660S2, HD 600, Massdrop X HD 6XX, HD 58X and similar models for a snug, secure fit.
• Ultimate Protection: Hardened EVA shell and reinforced molded structure resist impacts and distribute pressure so headphones survive rough handling and storage.
• Rugged Exterior: 1800D Twill nylon on the outside provides water resistance and extra cut and scratch protection for transport in bags.
• Plush Interior: Velvet lining and an internal strap prevent friction and keep the cups and headband from shifting during travel.
• Accessory Organization: A center compartment plus included carabiner, nylon bag, and Velcro cable tie let users store cables and small accessories without tangles.
• Durable Hardware: Hardened metal alloy zipper tabs, water-resistant zipper liner, and a rubberized grip on the handle improve longevity and carrying comfort.

Who It's For

The SPARTAN case is for audiophiles and commuters who own Sennheiser HD 600 series and related headphones and need a rugged, compact solution to protect those open-back models during travel or storage. It suits anyone who values a rigid shell and plush interior to prevent crushing and cosmetic wear.

Those who require a waterproof hard case for extended outdoor exposure or need storage for larger headphone setups with big aftermarket cables may want to consider a larger or fully watertight case instead. This model is optimized for portable protection and neat organization rather than aggressive all-weather submersion.

Frequently Asked Questions

Will my HD 600 fit with the cable attached?
For best fit and space you should unplug and tuck cables into the center compartment; the case fits headphones more securely if cables are removed.

Is the exterior fully waterproof?
The 1800D Twill nylon and water-resistant zipper liner resist splashes and light rain but the case is not designed for full submersion.

Does it protect against crushing in a packed bag?
Yes, the hardened EVA shell and reinforced molding are intended to distribute pressure and prevent headphones from being crushed during normal transport.
