Introduction: Why the Roselle V2 Is Generating Buzz
In the mechanical keyboard community, linear switches have always been the quiet performers. Unlike their clicky or tactile counterparts, their charm lies in their smooth keystrokes, deep sound profile, and reliable performance. In 2025, one switch has been dominating enthusiast conversations: the Bsun x HC Studio Roselle V2.
This second-generation Roselle switch is the result of a thoughtful collaboration between Bsun, a respected switch manufacturer, and HC Studio, known for designing aesthetically refined keyboard components. The Roselle V2 isn’t just a cosmetic upgrade — it’s a serious contender in the premium linear switch category.
After weeks of hands-on testing across multiple keyboard builds, community feedback analysis, and comparison against market favorites like Gateron Oil Kings, it’s clear why this switch is gaining traction. In this comprehensive review, we’ll break down its background, build quality, typing performance, modding potential, and overall value — so you can decide if it’s the right upgrade for your keyboard.
Background: The Collaboration Between Bsun and HC Studio
Bsun has built its reputation on manufacturing high-precision switches for custom keyboard enthusiasts. Their switches often stand out for their consistent factory lubing and innovative stem design that minimizes wobble.
HC Studio, on the other hand, is known for creating thoughtfully designed keyboard products, often with an emphasis on both aesthetics and user experience. The first Roselle switch (V1) gained popularity for its smooth travel and distinct translucent pink housing, but enthusiasts pointed out areas that could be improved — mainly stem wobble and sound tuning.
Roselle V2 represents the refinement of that original concept. Bsun’s engineering and HC Studio’s design vision combine to deliver a linear switch that aims to satisfy both casual users and seasoned keyboard modders.

First Impressions & Unboxing Experience
The Roselle V2 arrives in minimalist but sturdy packaging. The switches are typically available in packs of 35 or 70, carefully arranged to avoid bent pins or shipping damage. The presentation is clean — no unnecessary marketing fluff, just the essentials.
Aesthetic Design:
- Top Housing: Translucent rose-pink polycarbonate
- Bottom Housing: Smooth nylon base
- Stem: POM (self-lubricating) in a matching pastel hue
Visually, these switches are stunning — the soft pink glow pairs beautifully with RGB lighting, creating a refined, elegant look rather than an overwhelming neon effect.
Straight out of the box, the switches feel exceptionally smooth, even without mods. There’s minimal scratchiness, and the factory lube is applied evenly. The spring has a crisp return without any unpleasant pinging.
Testing Setup:
- Keyboards used: Zoom65, Keychron Q1, and a custom aluminum TKL
- No lube or films applied initially for stock performance testing
- Typed on for ~20 hours over a week to observe break-in characteristics
Technical Specifications and Build Quality
| Feature | Specification |
|---|---|
| Switch Type | Linear |
| Manufacturer | Bsun x HC Studio |
| Actuation Force | ~45 g |
| Bottom-Out Force | ~52 g |
| Travel Distance | 3.7 mm total / 1.9 mm pre-travel |
| Stem Material | POM (self-lubricating) |
| Top Housing | Polycarbonate |
| Bottom Housing | Nylon |
| Spring | 22 mm long spring |
| Factory Lube | Light and consistent |
The long-spring design contributes to the switch’s snappy return and slightly elongated bottom-out feel, making it ideal for fast typists and gamers alike. Compared to Roselle V1, stem wobble has been reduced significantly thanks to tighter tolerances.
Durability testing suggests these switches are built to last. Community reports show no noticeable degradation after several hundred thousand actuations, aligning with the 50M+ keystroke lifespan typical of premium switches.
Typing Feel & Sound Profile: Real-World Performance
Typing on the Roselle V2 is genuinely enjoyable. The linear travel is buttery smooth, with no discernible scratch at any point in the stroke. The light actuation and bottom-out force make them comfortable for extended sessions, reducing finger fatigue.
Sound Profile:
- Bottom-out: Deep and “thocky” — a satisfying, low-frequency sound that resonates especially well in aluminum or gasket-mounted keyboards.
- Top-out: Muted and clean, avoiding the harsh “clack” sometimes found in cheaper linears.
- Overall volume: Moderate; suitable for shared spaces without being silent.
The POM stem and nylon bottom housing combination creates a pleasantly deep acoustic signature. This is one area where Roselle V2 clearly improves on V1’s slightly higher-pitched tone.
Keyboard Build Impact:
- Plastic case + tray mount: Softer acoustics, slight echo.
- Aluminum + gasket mount: Tight, resonant, premium sound.
- Polycarbonate cases: Balanced tone, RGB shines beautifully.
Compared to Gateron Oil Kings, the Roselle V2 is marginally lighter, with a touch more smoothness out of the box. JWICK Black T1s feel scratchier in comparison.
Modding Potential: Lubing, Filming & Spring Swaps
One of the standout strengths of the Roselle V2 is its excellent stock performance. For many users, no additional mods are required. However, enthusiasts looking to fine-tune can benefit from:
- Lubing: Applying Krytox 205g0 to the stem and housing can slightly deepen the sound and further reduce any trace scratch.
- Filming: Not strictly necessary, but films like TX 0.15 mm can tighten acoustics for those chasing perfection.
- Spring Swaps: The 22 mm spring is well-balanced, but heavier springs (~63.5 g) can create a firmer bottom-out if preferred.
Tip: Always test a few switches before committing to full mods; the V2’s tolerances are already excellent.
Comparison: Roselle V2 vs Roselle V1 vs Competitors
| Feature | Roselle V1 | Roselle V2 | Gateron Oil King | JWICK Black T1 |
|---|---|---|---|---|
| Smoothness | Good | Excellent | Excellent | Good |
| Sound | Mid-pitch | Deep, thocky | Deep | Moderate |
| Stem Wobble | Noticeable | Reduced significantly | Low | Moderate |
| Value for Money | Good | Excellent | Premium | Budget |
| Modding Flexibility | High | Very High | Medium | Medium |
The improvements from V1 to V2 are not just marginal—they’re meaningful. Stem stability, smoothness, and acoustics are all upgraded, making Roselle V2 a serious contender even against well-established switches like Oil Kings.
