FAQ

Redragon BLUESIREN K654 vs DEVARAJAS K556 SE: your questions

The core difference is the switch type. The BLUESIREN K654 comes with clicky Outemu Red switches, while the DEVARAJAS K556 SE features linear Dragon Chant switches. This results in a tactile, audible typing experience versus a smooth, quiet one, respectively.

Yes, both the Redragon BLUESIREN K654 and DEVARAJAS K556 SE feature hot-swappable sockets. This allows you to change the mechanical switches without soldering. The DEVARAJAS vendor page specifically mentions a socket designed for high switch compatibility and easier mounting.

The DEVARAJAS K556 SE is likely better for a quiet office. Its manufacturer describes the included Dragon Chant switches as linear, which are typically quieter than clicky switches. The BLUESIREN K654 uses clicky switches, which provide audible feedback that can be disruptive.

Yes, both keyboards support proprietary software, according to their vendor descriptions. This software allows for customizing RGB lighting effects, creating macros, and potentially remapping keys for more efficient work or gaming setups.

The BLUESIREN K654 uses a mix of PBT and ABS keycaps. The DEVARAJAS K556 SE uses all PBT keycaps, which the vendor describes as 'zero-faded' and round in profile. PBT is generally more resistant to shine and wear than ABS.

Yes, both keyboards include sound dampening features. The BLUESIREN K654 lists 3.5mm sound absorbing foams. The DEVARAJAS K556 SE listing mentions a 'noise dampening kit.' These foams help reduce case reverberation for a more muted typing sound.

Both keyboards come with a detachable USB Type-C cable, a keycap puller, a user manual, and 8 spare switches. The BLUESIREN K654 includes spare Outemu Red switches, while the DEVARAJAS K556 SE includes spare Dragon Chant switches.

The DEVARAJAS K556 SE listing explicitly states support for computer systems including Mac OS X. The BLUESIREN K654 description does not specifically mention Mac support, so the DEVARAJAS is the safer choice for Mac users based on available information.

Yes, both are substantial full-size keyboards. The BLUESIREN K654 weighs 1.39 kg (1390g), and the DEVARAJAS K556 SE weighs 1.35 kg (1350g). This weight comes from their aluminum frames, which provide stability but make them unsuitable for frequent travel.

The DEVARAJAS K556 SE vendor page explicitly states 'Win Keys Can Be Disabled When Gaming.' This feature is not mentioned in the provided description for the BLUESIREN K654, though it may be possible through its software.

The BLUESIREN K654 features a unique gradient blue and white keycap color scheme. The DEVARAJAS K556 SE (in the Sakura Pink variant) has a solid pink and white aesthetic with round-profile keycaps and includes extra interchangeable accent keys for WASD and arrows.
