What will you mostly use it for?
The URANUS K737 Pro wins in scenarios demanding premium build, acoustics, and desk presence, such as office use, gaming, and content creation, thanks to its aluminum case, extensive dampening, and PBT keycaps. The ELF PRO K649 is the clear choice for travel due to its substantially lower weight and more compact footprint. For programming and general use, both keyboards are competitive, with the choice boiling down to layout preference and the value placed on a transparent aesthetic versus a metallic one.

Redragon ELF PRO K649 vs URANUS K737 Pro: your questions
The core difference is the case material. The ELF PRO K649 has a plastic case with a full-transparent design, while the URANUS K737 Pro features a CNC aluminum case. This results in a significant weight difference (950g vs 2020g) and alters the typing acoustics and perceived build quality.
The URANUS K737 Pro is likely better for a quiet environment. Redragon's listing specifies a five-layer noise dampening system including PO foam, IXPE switch foam, and PET pads. The ELF PRO uses a double foam dampening system, which may not be as effective at reducing hollow noise.
Yes, both keyboards are hot-swappable. The ELF PRO K649 listing states its sockets are compatible with nearly all 3-pin and 5-pin switches. The URANUS K737 Pro also features hot-swap functionality, allowing for easy switch customization without soldering.
The URANUS K737 Pro has a larger 4000mAh battery, while the ELF PRO K649 has a 3000mAh battery. According to the vendor description, the URANUS also includes a battery level indicator activated by pressing FN + Menu.
The URANUS K737 Pro explicitly lists Mac/Win support in its extra features. The ELF PRO K649's specifications do not mention Mac compatibility, so its support may be limited or require manual key remapping.
The URANUS K737 Pro comes with side-printed PBT contour line keycaps. The ELF PRO K649 comes with transparent keycaps, but the material (likely ABS or polycarbonate) is not specified as PBT in the provided information.
The ELF PRO K649 is significantly more portable. It weighs 950g compared to the URANUS's 2020g and has a shorter length (335mm vs 367mm). Its 78% layout is also more compact than the 80% TKL form factor of the URANUS.
The ELF PRO K649 includes the keyboard, a USB-C cable, a user manual, and four spare translucent switches. The URANUS K737 Pro includes the keyboard, a USB-C cable, a keycap & switch puller, a nano receiver, four spare switches, a user manual, and a sticker.
South-facing RGB means the LEDs are mounted on the south side (bottom) of the switch. This orientation prevents the LED housing from interfering with the lower profile of certain aftermarket keycaps, like Cherry profile, and can provide a more uniform under-glow lighting effect.
The stabilizers on the URANUS K737 Pro are screw-in stabilizers, which are typically easier to remove, lube, and mod compared to clip-in stabilizers. The ELF PRO K649's listing does not specify the type of stabilizers used.
The 78% layout of the ELF PRO K649 is more compact. It maintains a 65% length but adds a top row of function keys, resulting in 82 keys. The 80% TKL layout of the URANUS K737 Pro is a traditional tenkeyless design with 87 keys, which is wider as it includes a full navigation cluster.
