“70 keyboard” is an ambiguous label, not a reliable way to identify one standard layout. The two models covered here are both specified as 75% keyboards: Keychron lists the K2 Pro as an 84-key, 75% wireless keyboard, while NuPhy describes the Halo75 V2 as an ANSI 75% keyboard. If you are shopping by size, check the stated layout and key count rather than relying on “70” alone.
Neither model is established here as a tested winner. The useful choice depends on the features you need: connectivity, firmware customization, and support for changing switches.

What does “70 keyboard” mean?
The phrase does not identify a consistent layout in these product listings. Keychron uses “70 Layout Keyboards” as a category label, but its K2 Pro product page specifies 84 keys and a 75% layout. NuPhy calls the Halo75 V2 an ANSI 75% keyboard. Those model-specific descriptions are more useful than treating either board as a 70% model.

How to choose the right compact keyboard
- Confirm the layout. Look for the stated percentage, key count, and ANSI or other layout designation. Do not assume “70” means the same arrangement across brands.
- Decide how you will connect. If you need wireless, verify that it is explicitly supported for the exact model and revision. If you need a particular wired or wireless mode, confirm that mode on the manufacturer’s current specifications.
- Check customization needs. QMK/VIA support is listed for the Halo75 V2. The cited K2 Pro details establish wireless capability and hot-swap support, but do not specify firmware support.
- Match switches to the board. Hot-swap support is not universal switch compatibility. Check pin count and MX-style compatibility for the exact keyboard and switches; Keychron says the K2 Pro accepts most, not necessarily all, 3-pin and 5-pin MX-style switches.
- Consider your use together. A community post describes wanting a 75% wireless keyboard for gaming and productivity, with a stated budget of €100. That is one buyer’s example—not a survey or a current price recommendation. For gaming and work, list your required layout, connection, and customization features first, then verify each against the model’s specifications.
- Check keycap fit before buying accessories. Layouts and key sizes can vary. Confirm compatibility with the particular board before purchasing replacement keycaps or switches.
What to verify before ordering
- Current model revision, layout, and key count.
- Supported connection modes for the exact version you plan to buy.
- Whether the firmware features you want are supported.
- Switch pin and socket compatibility, plus any limits on which switches are hot-swappable.
- Keycap compatibility with the board’s layout and key sizes.
- Live price, availability, seller, and return terms; the cited product specifications do not establish current marketplace stock or pricing.
