The Contenders: Design & Build
Melgeek O2 – The first thing you’ll notice is the stunning retro-futuristic design. The translucent polycarbonate case, paired with RGB lighting that diffuses like neon, makes it look like a prop from Blade Runner. It’s a 75% layout (compact but keeps function keys), and the weighty aluminum plate eliminates any hollow echoes. However, the glossy finish is a fingerprint magnet, and at $200+, it’s undeniably a luxury pick.
IQUNIX MG65 – Slightly more subdued but no less premium, the MG65 sports a sleek aluminum frame with a sandblasted finish. It’s also a 75% keyboard but opts for a lower profile, making it easier to toss in a bag. The stock keycaps (PBT dye-subbed) feel textured and durable. At ~$150, it’s more affordable, though the RGB lighting is less dramatic than the O2’s.
Winner for Portability: MG65 (lighter and thinner).
Winner for Aesthetics: O2 (if you love eye candy).
Typing Experience: Sound & Feel
Both keyboards support hot-swappable switches (a must for tweakers). I tested them with Gateron Pro Yellows (smooth linear) and Boba U4Ts (tactile).
- O2: The polycarbonate case creates a deeper, slightly muted sound profile—think thocky rather than clacky. The stabs are factory-lubed well, with minimal rattle. The gasket mount adds a bouncy feel, great for long coding sessions.
- MG65: The aluminum body gives a sharper, higher-pitched sound, though foam modding helps. Typing feels sturdier, with less flex than the O2. The Kailh Box switches I tried felt snappier for gaming.
For Writers/Programmers: O2 (softer acoustics, gentler on the wrists).
For Gamers/Typists Who Prefer Feedback: MG65 (more tactile response).
Mac Compatibility & Extras
- Both work flawlessly with Macs via Bluetooth or wired USB-C. The O2 includes a dedicated macOS keycap set, while the MG65 relies on secondary legends (annoying but workable).
- The O2’s knob controls volume/media, a killer feature for Mac users. The MG65 lacks a knob but has better shortcut integration (e.g., Mission Control via F3).
- Battery life: ~3 weeks on both (with RGB off).
The Verdict
If you’re after a showstopper keyboard that feels as good as it looks—and don’t mind the price—the Melgeek O2 is my top pick. It’s the keyboard I keep on my desk for writing and design work.
But if you want a more affordable, travel-friendly workhorse with sharper tactile feedback, the MG65 is the smarter choice. It’s the one I’d take to coffee shops or LAN parties.
Final Tip: If you’re coming from a Keychron, both will feel like massive upgrades in sound and build quality. Just don’t blame me when you fall down the custom-keyboard rabbit hole!
