Hyekit PBT 137-Key Melody of The Sea Keycap Set - Durable XDA Caps

In this review the Hyekit PBT Melody of The Sea 137-key set is judged as a budget-minded upgrade for mechanical keyboard owners who want a cohesive, comfortable typing surface. It is aimed at people rebuilding layouts across 61 to 108-key boards who value a durable, matte PBT feel and consistent legend longevity. The single biggest reason to buy is the combination of thick PBT walls and dye-sublimated legends, which together deliver a long-lasting, grease-resistant keyset that still feels pleasant under the fingers.

Key Features

• Wide compatibility: The 137-key kit includes enough keys and common sizes to fit most 61/64/68/75/84/87/96/104/108 layouts, making it useful for custom and prebuilt boards.
• Durable PBT material: High-quality PBT construction with an anti-grease coating reduces shine and grime buildup for longer daily use.
• Dye-sublimation printing: Legends are infused into the plastic for vivid, long-lasting color that resists fading and oil stains.
• XDA profile: The uniform, low-profile XDA shape increases contact area and delivers a comfortable, slightly rounded top that many describe as soft and marshmallow-like.
• Extra-thick key walls: Thicker walls provide a solid, satisfying feel and improved durability for heavy typists and frequent keypresses.

Who It's For

This set is a solid choice for hobbyists and everyday typists who want a complete, visually consistent replacement for stock ABS caps without spending heavily. It particularly suits owners of compact and full-size mechanical keyboards who need extra modifier and specialty keys to support multiple layouts.

People who want premium sculpted profiles like SA, or those requiring backlit legends for RGB through-lighting, should look elsewhere; the XDA profile and dye-sublimated legends prioritize feel and durability over translucent illumination.

Pros & Cons

Pros

• Pleasant matte feel and increased contact area from the XDA profile, which many customers call comfortable.
• Legend durability from the dye-sublimation process so characters stay vivid with regular use.
• Good value for a 137-key kit that covers most layouts and includes extra keys for customization.
• PBT construction and anti-grease coating reduce shine and grime over time.

Cons

• Uniform XDA profile may not satisfy users who prefer sculpted rows or backlight-friendly translucent legends.
