Leobog Hi75 Keyboard Review: Aluminum 75% Beauty

The Leobog Hi75 pairs a stunning CNC aluminum case with gasket mount and hotswap PCB at ¥299 (~$41.53). ✅ Worth Buying — it delivers one of the best stock typing experiences under ¥400 with premium build quality that rivals keyboards twice its price.

Introduction

Leobog (a sub-brand of MCHOSE/VGN) has become known for delivering premium materials at competitive prices. The Hi75 is a 75% layout keyboard in a solid CNC aluminum case that weighs in at over 1.8kg — a true desk anchor. It’s designed for typing enthusiasts who prioritize sound and feel above all else.

The Hi75 has become something of a legend in the Chinese keyboard community, frequently selling out and spawning a vibrant modding scene. Its stock sound profile — a deep, resonant thock with minimal pinging — rivals custom keyboards many times its price. At ¥299, it sits between the budget plastic boards and the premium ¥600+ options, offering a compelling middle ground.

Design and Build Quality

The Hi75’s aluminum case is the star attraction. It’s made from a single piece of CNC-machined aluminum with a sandblasted anodized finish available in several colors (white, black, blue, pink, purple). The case walls are thick, contributing to the 1.8kg weight that makes the keyboard feel immovable on the desk.

The gasket mount implementation is well-executed with silicone gaskets that provide a satisfying bounce to every keystroke. The PC plate flexes noticeably under typing, and the combination of aluminum case, gasket mount, and internal foam layers produces a genuinely premium sound profile. The spacebar is particularly impressive — deep, solid, and rattle-free.

The Hi75 comes with PBT double-shot keycaps in a choice of colorways. The stock keycaps are OEM profile with good thickness and crisp legends. The stabilizers are screw-in and factory-lubed — among the best stock stabilizers in this price range with minimal rattle.

One important note: the Hi75 is a wired-only keyboard. There is no Bluetooth or 2.4GHz wireless option. The USB-C port is on the back and accommodates most aftermarket cables.

“I have keyboards that cost ¥1,000+ and the Hi75 holds its own against all of them. The stock sound is incredible — deep, thocky, with zero case ping. The aluminum case is stunning. Best ¥299 I’ve ever spent.” — JD Verified Buyer, rated 5/5

Performance

As a wired-only keyboard, latency is effectively zero. The 1000Hz polling rate ensures responsive input for competitive gaming. The hotswap PCB supports both 3-pin and 5-pin switches.

The stock switches on the Hi75 vary by version. The most common configuration uses Leobog’s Nimbus linear switches, which are factory-lubed and feel smooth with minimal scratch. The sound profile is defined more by the case construction than the switches — even budget switches sound good in the Hi75’s aluminum chassis.

For gamers, the 75% layout is nearly ideal — compact enough for ample mouse room while retaining the function row. The south-facing RGB LEDs provide under-key lighting, though the aluminum case means there’s no under-glow or side lighting.

“I primarily play Valorant and CS2. The Hi75 feels great for gaming — responsive, no lag, and the compact layout gives me plenty of mouse space. The weight keeps it planted during intense flicks. Highly recommend for FPS players.” — JD Gaming Buyer, rated 4.7/5

What Chinese Users Say

Build Quality and Sound (做工与声音): “The aluminum case is beautiful and the typing sound is the best I’ve heard on any stock keyboard under ¥500. Deep, satisfying thock with every stroke. Worth every yuan.” — JD review, 5/5

Weight and Premium Feel (重量/质感): “This keyboard weighs 1.8kg — it’s not going anywhere. The anodized finish feels premium and the CNC machining is clean with no sharp edges. Desktop jewelry.” — JD review, 4.9/5

Value Discussion (性价比): “¥299 for an aluminum gasket keyboard with this sound profile is incredible value. You’d pay ¥599+ for equivalent quality from Keychron or NuPhy.” — JD review, 5/5

Wired Limitation (有线限制): “The only downside is no wireless. I wish there was a wireless version. The wire is a minor inconvenience on my clean desk setup. Wired purists won’t mind.” — JD review, 4.3/5

Purchase Recommendations

• ✅ Worth Buying — If you want the best typing sound and build quality under ¥400, the Hi75 is unmatched. The aluminum case and gasket mount deliver a premium experience.
• 💰 Premium Pick — For those who need wireless, the VGN N75 Pro offers similar features in a plastic case with tri-mode connectivity at ¥199. You can’t get both wireless and aluminum at this price.
• ⚠️ Budget Warning — If ¥299 is too much, the Ajazz AK820 Pro at ¥169 offers a screen and tri-mode in a plastic case — less premium but more features.
