Top 5 Things to Know Before Buying Mode Sonnet

Introduction – Why the Mode Sonnet Deserves Your Attention

Custom mechanical keyboards have become more than just tools — they’re now personal projects, collector pieces, and creative expressions. Whether you’re a gamer, developer, writer, or design enthusiast, the right keyboard can transform your daily typing experience. But not all keyboards are created equal, and that’s where the Mode Sonnet stands out.

Built by Mode Designs, a respected name in the mechanical keyboard community, the Mode Sonnet offers premium materials, customizable layouts, and a sound profile that many describe as “thocky” — that satisfying, deep keystroke sound enthusiasts chase. It’s a 75% mechanical keyboard kit, meaning it strikes the perfect balance between compactness and functionality, retaining keys like arrows and function row while cutting out the numpad.

If you’ve been eyeing a high-end board but aren’t sure if the Sonnet is the right fit, you’re not alone. Many users have questions:

• What’s in the box?

• How much does it actually cost to build one?

• Is it beginner-friendly or only for seasoned builders?

In this guide, we’ll cover the top 5 things you need to know before buying the Mode Sonnet. From build quality to customization options and real costs, this post will help you make an informed decision, whether you’re a first-time buyer or looking to upgrade from your current setup.

1. Mode Sonnet Is a High-End Customizable Keyboard Kit

The Mode Sonnet isn’t your average mechanical keyboard. It’s a premium 75% keyboard kit designed for users who want full control over how their board looks, sounds, and feels. Unlike prebuilt keyboards, the Sonnet arrives as a modular kit, giving you the freedom to build your ideal typing experience from the ground up.

What Comes in the Box?

When you order the Mode Sonnet, you’re getting a thoughtfully engineered base kit that includes:

• Top and bottom case (various materials and finishes)

• PCB (choose between hot-swap or soldered options)

• Plate (the surface where your switches mount)

• Mounting system (either isolated top mount or stack mount)

The essentials are all there, but Mode also offers a range of optional add-ons to fine-tune your build:

• Internal weights (stainless steel or brass) to add heft

• Dampening foam kits to modify sound and keystroke feel

• Magnetic accent bars to customize the look of your board

Everything comes neatly packaged and ready to assemble—just add your preferred switches, stabilizers, and keycaps.

Customization Options That Set It Apart

What makes the Mode Sonnet keyboard so appealing is its deep level of customization. You’re not just buying a keyboard—you’re designing one that fits your style and preferences.

Materials That Matter

The Sonnet’s case is available in multiple materials, each offering its own weight, texture, and acoustics:

• Aluminum – lightweight, durable, and classic

• Brass – solid and heavy, with a deeper sound profile

• Copper – rich in color, weighty, and uniquely stylish

• Polycarbonate – translucent, flexible, and softer-sounding

Plates That Define Typing Feel

The plate sits between your switches and PCB and affects both feel and sound. Options include:

• FR4 – balanced and slightly soft, great for everyday use

• Polycarbonate (PC) – very soft and quiet

• POM – smooth and flexible

• Brass – stiff and loud with a crisp keystroke

• Carbon Fiber – lightweight with a slightly hollow, resonant sound

Mounting Styles for Sound and Flex

The Sonnet supports two main mounting methods:

• Isolated Top Mount – more flexible, open sound; great for soft and bouncy typing

• Stack Mount – firmer and more muted; better for a solid, dampened feel

The beauty of the Mode Sonnet lies in how it lets you create something truly personal. Whether you’re after a deep, satisfying “thock,” a softer, cushioned feel, or a clean aesthetic with luxurious materials, this keyboard kit gives you the tools to make it happen.

2. Mode Sonnet Build Quality Is Premium — but Hefty

The Mode Sonnet isn’t just about looks — it’s built like a tank. From the materials used to the way each part fits together, this keyboard screams high-end. But with that premium build comes a noticeable heft, especially if you go for heavier options like brass or copper.

Material and Finish Impact Both Feel and Sound

The material you choose for your Sonnet affects more than just appearance — it plays a huge role in the overall typing experience.

• Brass and copper builds can weigh between 3 to 7 pounds, making the keyboard feel incredibly solid on your desk. These materials also give a deeper, more resonant sound when typing.

• Aluminum, by contrast, is lighter and offers a sharper, more neutral sound.

• Polycarbonate feels softer and more flexible, with a quieter, more muted typing profile.

Your choice of top and bottom case materials, plate, and internal foam will all influence how the board sounds and feels in use. Whether you’re aiming for a soft, “marbly” feel or a crisp, clicky response, the Sonnet gives you the building blocks to achieve it.

Attention to Detail in Craftsmanship

Mode Designs doesn’t cut corners, and it shows. Every part of the Sonnet is manufactured with tight tolerances, meaning the pieces fit together perfectly with no gaps, rattles, or rough edges. The machining is precise, and the anodized or polished finishes are clean and consistent.

One of the standout design touches is the magnetic accent bar. Instead of being glued or screwed in, it attaches securely with magnets. This not only makes it easy to swap out colors and materials (like brass, copper, or walnut) but also keeps the build sleek and screw-free from the outside.

Little things like this elevate the Mode Sonnet keyboard from a hobbyist kit to something that feels more like a designer product — one that’s built to last and look good doing it.

In short, the build quality of the Mode Sonnet matches its price. It’s solid, refined, and meticulously engineered — but expect some weight, especially if you lean into the heavier configurations.

3. It’s Not Prebuilt — You’ll Need to Assemble It

One of the most important things to know about the Mode Sonnet is that it’s not a prebuilt keyboard. It comes as a DIY kit, which means you’ll be putting it together yourself. For some, that’s the fun part. For others, it might be a dealbreaker.

A Fun Challenge for Hobbyists

If you enjoy building things or customizing gear to match your exact preferences, the Mode Sonnet is made for you. From choosing the plate material to selecting switches and dampening foam, every detail is in your hands.

The Sonnet supports both hot-swap and soldered PCBs:

• Hot-swap PCBs let you install switches without soldering, making them great for beginners or those who like to change switches often.

• Soldered PCBs require more skill and tools but allow for broader layout options, including ISO.

Building the Sonnet can be a rewarding experience, especially if you enjoy the process of fine-tuning your typing feel and sound.

Not Ideal for Plug-and-Play Seekers

If you’re looking for a keyboard you can pull out of the box and start using immediately, this isn’t it.

The Mode Sonnet keyboard kit does not include switches, stabilizers, or keycaps. You’ll need to purchase those separately, and possibly a few tools if you choose a soldered PCB. Here’s a basic list of what you’ll need to complete the build:

• Mechanical switches (your choice: linear, tactile, or clicky)

• Plate-mounted or screw-in stabilizers

• Keycaps (compatible with 75% layout)

• USB-C cable (not always included)

• Optional: lube, switch puller, soldering kit (if applicable)

While this might seem like a lot, it also means you get to tailor every part of the board to your liking — from the sound of each keystroke to the height and feel of the caps.

The bottom line? Mode Sonnet is best suited for those who enjoy the process of building and customizing. If you’re willing to put in the time (and a bit of extra budget), the result is a premium keyboard that feels completely your own.

4. Pricing Varies Based on Your Configuration

What’s the Starting Price of Mode Sonnet?

The Mode Sonnet starts at around $299 USD for the barebones kit. This includes the essentials—case, plate, PCB, and internal components—but leaves out key switches, stabilizers, and keycaps. This base price gives users the flexibility to build their perfect keyboard from the ground up, but it’s important to know that this is just the starting point.

Full Build Costs Can Add Up

Once you factor in high-quality switches, custom keycaps, upgraded weights, and accent bars, your Mode Sonnet build can easily climb into the $450 to $700+ range. For example, a brass or copper weight adds both aesthetics and cost, while GMK keycap sets alone can cost over $100.

Compared to other premium 75% custom keyboards, the Sonnet sits competitively. Similar boards like the GMMK Pro or Keychron Q1 may have lower entry points, but they often lack the same level of material customization, finish options, and build quality.

So, if you’re budget-conscious, plan your configuration carefully. But if you value flexibility, craftsmanship, and premium materials, the Mode Sonnet justifies its price tag.

5. Mode Sonnet Is Loved for Typing Feel and Acoustics

Excellent Sound Dampening and Custom Acoustics

One of the biggest reasons people choose the Mode Sonnet is for its outstanding typing sound and acoustic tuning. Whether you’re chasing a deep “thock” or a soft, muted sound, the Sonnet gives you room to dial it in your way.

You get several foam options (plate foam, case foam, and PE foam) right out of the box, helping reduce unwanted ping and hollow sounds. Combine that with gasket mount or stack mount choices, and you’ve got a highly tunable sound profile. Most users report a balanced, satisfying sound that’s neither too loud nor too dampened.

If you’re into custom keyboards for that buttery, clean sound signature, the Mode Sonnet delivers.

Comfortable Typing Experience

Sound aside, the typing experience on the Mode Sonnet is just as impressive. It features a 5.5° typing angle, which strikes a great balance between ergonomics and aesthetics. It doesn’t strain your wrists like steeper boards often do.

The low front height (~19mm) also makes it comfortable to type on for long sessions, even without a wrist rest. Whether you’re coding, writing, or gaming, the Sonnet feels natural under your fingers.

For those who care about both feel and sound, the Mode Sonnet is one of the top custom keyboards in the 75% layout category.

It’s a premium board, but you’re paying for top-tier materials and a personalized build.

The hot-swap option makes it much easier for beginners, and Mode’s online resources and community support can guide you through the build process.

Can I buy a prebuilt Mode Sonnet?

No, the Mode Sonnet is sold only as a kit. That means you’ll need to purchase and install your own switches, stabilizers, and keycaps. It’s designed for people who enjoy customizing and building their keyboard from scratch, not for those looking for an out-of-the-box solution.
