Epomaker Split70 vs TH99Ergonomic Split vs Compact Numpad

The Epomaker Split70 is specifically designed for this purpose. Its split layout allows you to position each half to align with your shoulders, reducing inward rotation of the wrists and forearms. The TH99 has a standard layout with an adjustable kickstand, which helps with tilt, but does not address shoulder width alignment like a split keyboard can.

No, according to a manufacturer response to a customer review, both halves of the Split70 need to be connected for the keyboard to function, even in wireless mode. They are linked together with an included USB C-to-C cable to form a single system that then communicates wirelessly with your computer.

No. The technical specifications for the Epomaker TH99 explicitly state it is not compatible with PS4, PS5, or Nintendo Switch. It is compatible with Mac, Windows, and Android devices.

Based on manufacturer claims, the TH99 has a significantly longer estimated battery life. The TH99 is listed for up to 800 hours with backlight off, while the Split70 is listed for 260 hours with backlight off. The TH99 also has a larger 4000mAh battery compared to the Split70's 3000mAh.

Yes. The Epomaker Split70 supports VIA and QMK, which are open-source firmware tools that allow you to remap every key, create complex macros, and adjust lighting layers in real time without flashing firmware. The TH99 uses proprietary driver software for customization.

The TH99 offers a choice between two pre-lubed switch options. You can get it with the Creamy Jade switch, which is a linear switch, or the Sea Salt Silent switch, which is a silent linear switch designed for quieter operation.

Yes, both the Split70 and the TH99 feature hot-swappable sockets. The Split70's listing confirms it supports both 3-pin and 5-pin mechanical switches. The TH99 also supports 3-pin and 5-pin switches.

The Epomaker Split70 is more portable. It weighs 890g, which is less than half the weight of the 2000g TH99. Furthermore, its split design can sometimes allow for more flexible packing, though it is two separate pieces to manage.

Yes, both keyboards feature per-key RGB backlighting with south-facing LEDs. South-facing LEDs are often preferred as they provide better compatibility with Cherry-profile and other sculpted keycap sets without interference.

The Split70 comes with the keyboard, a USB A-to-C cable, a USB C-to-C cable to connect the halves, three Mac modifier keycaps, three extra switches, a 2-in-1 switch and keycap puller, a multilingual manual, and a quick start card.

The Split70 uses a 70% split ergonomic layout, meaning it has 71 keys and a knob, and the board is physically divided into two separate halves. The TH99 uses a 96% layout, which condenses a full-size keyboard with numpad into a more compact form by removing some of the spacing between key clusters.

Both keyboards have a 1000Hz polling rate in wired and 2.4GHz modes. The manufacturer lists a 3ms latency for the Split70 in wired mode and a 2ms latency for the TH99 in wired mode. In practice, both are sufficiently low for competitive gaming, with the difference being negligible for most users.
