YUNZII B87 Wireless Mechanical Keyboard Review: Premium Sound at Budget Price

Looking for a wireless mechanical keyboard that sounds as good as it performs? The YUNZII B87 has been making waves in the budget keyboard community for delivering premium sound at an accessible price.

The YUNZII B87 is a wireless TKL mechanical keyboard featuring 87 keys, tri-mode connectivity (Bluetooth, 2.4GHz, and USB-C), and a 5-layer gasket mount structure. At $71.99 with a 4.8-star rating from 348 reviews on Amazon, it promises enthusiast-level features without the enthusiast-level price tag.

I put the B87 through its paces, testing the typing feel, wireless connectivity, and comparing it directly against other keyboards in my collection. The sound tests and switch swaps revealed a lot about what makes this keyboard stand out.

The short answer? It earns its reputation as one of the best sounding budget mechanical keyboards available. But there are a few things you should know before buying.

What I Liked

Premium Sound from 5-Layer Gasket Mount

The gasket mount structure is where the YUNZII B87 truly shines. Inside the keyboard, five distinct layers work together to create that sought-after creamy, thocky sound profile. The PE sandwich foam sits between the plate and PCB to soften the sound, while the IXPE switch pad evens out the acoustics across the entire board.

The PET sound foam prevents that hollow case resonance that plagues cheaper keyboards. Add in the extra switch foam for cushioned keypresses and a silicone bottom pad for vibration absorption, and you get surprisingly refined acoustics for under $80.

Smooth Cocoa Cream V2 Linear Switches

The pre-lubed Cocoa Cream V2 linear switches deliver exactly what the name promises: a smooth, creamy typing experience. These switches bottom out without any tactile bump, making them ideal for fast typists and gamers alike.

The factory lubrication means no scratch or ping out of the box. The 50-gram spring weight hits a comfortable middle ground that works well for extended typing sessions.

Versatile Tri-Mode Wireless Connectivity

Connecting to your devices is straightforward with three options. Bluetooth lets you pair up to five devices and switch between them on the fly. The 2.4GHz wireless dongle (cleverly stored under the keyboard’s height adjustment foot) provides low-latency gaming performance.

USB-C wired mode rounds out the options when you need a guaranteed connection or want to charge while using. The seamless switching between modes works exactly as advertised.

Hot-Swappable Switches for Customization

The hot-swap sockets accept both 3-pin and 5-pin mechanical switches without any soldering. This opens up the entire world of aftermarket switches for customization.

The included switch puller makes swapping straightforward. Whether you want tactile feedback for office work or lighter linears for gaming, you can change the feel of this keyboard in minutes.

Generous Included Accessories

Opening the box reveals more than just a keyboard. YUNZII includes a soft-touch wrist rest that matches the keyboard’s aesthetic, a cheat sheet for function key shortcuts, extra switches for spares, and decorative keycaps with hearts and flowers.

Having Mac Command keycaps included is a thoughtful touch for Apple users. Many keyboards in this price range skip these extras entirely.

Space-Saving TKL Layout

The 87-key TKL layout removes the number pad while keeping the function row and navigation cluster intact. This frees up substantial desk space for mouse movement without sacrificing essential keys.

For gaming and general productivity, this 80% layout hits the sweet spot between full-size functionality and compact convenience.

What Needs Improvement

RGB Brightness Could Be Better

The south-facing RGB backlighting looks good, but it’s noticeably dimmer than many competing keyboards. In a well-lit room, the lighting effect is subtle rather than bold. RGB enthusiasts who want their keyboard to pop in bright environments may find this limiting.

The various lighting modes and effects work well, and you can adjust brightness through the function keys. Just set expectations accordingly if vibrant RGB is high on your priority list.

Plastic Wrist Rest Material

The included wrist rest is a nice addition, but the plastic construction could be softer. It does the job and matches the keyboard aesthetically, but memory foam or silicone would provide better comfort during long sessions.

This is a minor issue since aftermarket wrist rests are readily available and inexpensive.

Bluetooth Wake Delay

When the keyboard enters sleep mode on Bluetooth, there’s a brief delay before it wakes up and registers your first keypress. This typically lasts about a second or two. For most typing scenarios, it’s barely noticeable.

Gamers or users who need instant response can avoid this entirely by using the 2.4GHz wireless or wired connection.

How It Compares

YUNZII B87 vs RK Royal Kludge

In a direct sound comparison, the YUNZII B87 outperformed the RK Royal Kludge despite similar pricing. The B87’s layout gives keys more breathing room, especially around the arrow cluster where the RK felt cramped.

The B87’s dedicated navigation keys sit comfortably separated from the main key area. This makes accidental key presses less likely during fast typing or gaming. The RK keyboard packed more keys into a similar footprint, which created a tighter layout that some users may find challenging.

YUNZII B87 vs Keychron V3 Max

The Keychron V3 Max is a common alternative in the budget gasket-mount category. Both offer QMK/VIA support and similar build quality. However, the V3 Max only provides Bluetooth connectivity for wireless use.

The B87’s 2.4GHz wireless mode gives it an edge for gaming, where the lower latency matters. If you exclusively need Bluetooth, the Keychron remains competitive. For mixed use including gaming, the B87’s tri-mode connectivity provides more flexibility.

Sound Test Results

Testing all three keyboards with linear switches revealed clear differences. The B87’s 5-layer dampening produced the smoothest, most refined sound. The thock was deeper and the overall typing acoustics felt more premium than both competitors.

For buyers prioritizing sound quality in this price range, the B87 delivers exceptional value.

Final Verdict

The YUNZII B87 earns a 4.6 out of 5 rating for delivering exceptional sound quality and comprehensive features at an accessible price point.

This keyboard proves you don’t need to spend hundreds of dollars for premium typing acoustics. The 5-layer gasket mount, pre-lubed switches, and thoughtful dampening create a typing experience that competes with keyboards costing twice as much.

The tri-mode wireless connectivity, hot-swap capability, and QMK/VIA support give you room to customize and grow. Minor limitations like dimmer RGB and a plastic wrist rest don’t detract from the core value proposition.

If you want a great-sounding mechanical keyboard with modern wireless features and customization options under $80, the YUNZII B87 delivers exactly that.
