Best for

What will you mostly use it for?

The Dharma K556 wins for gaming and travel due to its wireless options and compact size. The Trundle K668 is better suited for office work and content creation where a numpad and extra macro keys are valuable. For programming and modding, the choice is less clear and depends on the user's preference for layout size versus the unique gasket mount and keycap style of the K668.

For gaming

FAQ

Redragon DHARMA K556 vs TRUNDLE K668: your questions

Yes. The Redragon Dharma K556 offers tri-mode connectivity, which includes USB-C wired, Bluetooth, and 2.4GHz wireless options according to its product listing. It has a built-in 1600mAh battery to power the wireless modes.

Yes. The Trundle K668 is a full-size keyboard with a 108-key layout. This includes a standard numpad and four additional dedicated hotkeys for functions like mute and calculator, as stated in the vendor description.

The Redragon Dharma K556 is better for a small desk. Its 80% TKL (tenkeyless) layout is significantly more compact than the full-size Trundle K668, freeing up valuable space for your mouse or other items.

Yes, both the Dharma K556 and Trundle K668 feature hot-swappable sockets. This allows you to easily remove and replace the mechanical switches without soldering. Both packages include a switch puller and spare switches.

The Redragon Trundle K668 comes with PBT round keycaps. The vendor description specifies the material as PBT, which is known for its durability, and the unique round shape offers a different typing experience compared to standard keycaps.

A gasket mount is a design where the keyboard's internal plate is suspended by rubber or silicone gaskets within the case. Redragon's description states the K668 uses this structure, which can reduce harsh vibrations and create a softer, more cushioned typing feel.

The Redragon Dharma K556 is more portable. Its smaller TKL size, lighter weight (870g vs 880g), and wireless Bluetooth capability make it much easier to move around and use with different devices compared to the wired, full-size Trundle K668.

The Redragon Dharma K556 listing explicitly states Win/Mac dual system support. The listing for the Trundle K668 does not specify Mac compatibility, so it is recommended to verify this with the manufacturer if it is a requirement.

The Redragon Dharma K556 comes pre-installed with linear Quiet Red switches. The vendor description notes these are quiet, basic linear switches designed for a soft key travel and are paired with sound-absorbing foam.

Yes. According to its product features, the Redragon Trundle K668 is software supported. This allows for advanced customization of RGB lighting effects and programming of macros or key bindings through Redragon's software.

Both keyboards incorporate sound-dampening features. The Dharma K556 uses 3.5mm sound absorbing foam with its Quiet Red switches. The Trundle K668 also has built-in noise-dampening foam. The actual sound level will depend on the specific switches used.

The Dharma K556 includes the keyboard, a USB Type-C cable, a keycap & switch puller, a sticker, four spare switches, and a user manual. The Trundle K668 includes the same items: the keyboard, a detachable USB Type-C cable, a puller, four spare switches, a manual, and a sticker.
