ASUS ProArt Keyboard KD300 - 26.8mm Ultra-Slim 65% Low-Profile

I always find myself paying attention whenever a new keyboard comes out, and this time the ProArt KD300 caught my eye with a spec sheet that includes a 26.8mm thickness and support for 5 simultaneous device connections. The fact that it's a low-profile mechanical keyboard with up to 16 months of battery life also stood out to me from a real-world usability perspective.

🔍 Why I'm Interested

Slimness at 26.8mm combined with a mechanical feel

When you hear "low-profile," membrane switches usually come to mind first, but what caught my attention here is that ASUS uses RX Red low-profile optical switches, so the board stays thin while still delivering a mechanical typing feel.

5-device connection + tri-mode

It supports 2.4GHz, Bluetooth, and wired USB all at once, and you can pair it with up to 5 devices — this seems like a great fit for the workflow of creative workers who bounce between a PC, tablet, and laptop. The dedicated PC/Mac switch is also a thoughtful touch.

Up to 16 months of battery life

Up to 16 months with RGB off, and 100 days even at full brightness — that kind of battery longevity really stands out among low-profile wireless keyboards. It looks like a meaningful boost to everyday usability by cutting down on charging stress.

Touch panel and magnetic dongle storage

A touch panel for controlling volume, media, and lighting, plus a slot where the dongle magnetically snaps into place for storage — these little details feel very much in line with the polish you'd expect from the ASUS ProArt lineup.

🤔 Points of Concern

Global retail price not yet confirmed

Right now the only confirmed figure is the China launch price (CNY 999), so we'll need to wait and see what the global and local retail price ends up being.

Getting used to the 65% layout

It does have arrow keys and navigation keys, but the layout is more compact than a full-size board, so if you frequently use a numpad, you may need some time to adjust.

🛒 Before You Buy

✅ Recommended for

• Creative workers who move between multiple devices
• Anyone who wants a slim desk setup without giving up a mechanical typing feel

❌ Not recommended for

• Anyone who needs a full-size numpad
• Buyers who only purchase products with confirmed local retail availability and after-sales support

🎯 Final Verdict

ASUS's ProArt lineup is aimed at creators, so it tends to be detail-oriented, and the KD300 shows clear signs of trying to have it all — slimness, battery life, and connectivity. In particular, that 16-month battery life is a genuinely impressive spec for a low-profile wireless keyboard.

That said, since the global retail price hasn't been finalized yet, it's worth keeping an eye on what the actual price looks like at launch. If you're on the hunt for a minimalist low-profile keyboard, this is one to keep watching for release updates.
