I’ve been using and testing the Roseselsa Ceramics MK2 for the last couple of weeks. There’s been a quite a bit hype and talk on forums and YouTube lately. People are calling these a sub-$30 "Sound King."
TLDR: If you care about audio quality for the cash, they live up to the hype. But if you’re expecting a flawless, seamless lifestyle earbud for your daily commute, there are a few things to note.
Price: ~$32.99 USD
Pros:
Comfort, design and build quality:
You get a smooth, bean-shaped plastic body with a clean matte finish. It looks elegant and feels nice to touch although a bit slippery. The gold accent vents on the outer faceplates provide a touch of aesthetic personality. The housings are lightweight at just 4.3g. Sits comfortably in the ear concha without creating hot spots or pressure points.
For ergonomics, the elongated nozzle sits at a natural angle for a medium-to-deep insertion. Multiple users note that comfort is an easy 10/10 for long sessions, and I agree. I say it is not an ideal companion for the gym or heavy running though. Because of the stemless, smooth design, sweat or sudden movement can cause the buds to slowly slip out of place. It’s better used at a desk. It also works well for walks.
About the stock ear tips. I found them a bit thin, small, and flimsy to create a proper seal. Using the stock tips, I found that the sub-bass is lacking slightly. This causes the buds to sound thin, hollow, and sharp. I swapped them out for SpinFit ear tips, there is enough interior clearance in the casing. Doing so made a big improvement. They secure an instant acoustic seal. The buds still snap into the case to charge with no interference. Once you fix the seal, the driver wakes up.
The case handles daily pockets easily. The lid layout works great. It utilizes a rigid, dual-layered internal plastic shell. This holds the case open when placed flat on a table. Opening and closing the case, you can feel the magnetic force and of course, the satisfying snap of the case.

Pairing for the tests:
Sound signature:
The low end values control and speed. There is a roll-off below 50Hz in the deepest sub-bass. Bassheads looking for a heavy V-shape might find it a bit lean. Out of the box, the titanium driver benefits from some burn-in time to let the diaphragm stretch. However, the mid-bass features a clean 3dB to 5dB lift between 100Hz and 200Hz. This gives the music plenty of tight punch, texture and rhythm. It decays quickly. It avoids introducing bleed or muddy clouding into the midrange.
The tuning feels smooth, linear and organic. It avoids the thin or colored character typical of cheap budget buds. The mids stay clear. This allows instruments to separate cleanly with a natural note weight. Vocals are positioned slightly forward. Male voices carry an appropriate warmth without getting boxy. Female vocals sound fresh, smooth and velvety. They maintain air without becoming dry, nasal or shouty.
The treble is smooth and safe for long listening sessions. There is a deep, intentional drop right in the 4kHz to 5kHz range, which acts as a shield against sharp piercing or harshness from bad recordings. Right after that drop, the response climbs back up past 6kHz to bring back air and crisp sparkle. High-hats and cymbals sound lively and drop off naturally, but they never tire your ears out. It presents fine details gracefully instead of aggressively forcing a sharp, clinical sound into your ears.
The left-to-right soundstage width is the the standout feature. Vertical height and depth layering could be better, the horizontal stage is surprisingly wide for a closed wireless bud. It pushes sound cues well outside the borders of your head. The imaging is reliable too, allowing you to easily pinpoint exactly where an instrument or sound is placed without any messy or confusing overlap.
Gaming:
Make sure to enable the 47ms Game Mode.
Explosions, gunfire and impacts feel exciting. They do not turn into a fatiguing wall of muddy sound. Turning on Game Mode drops the latency.
Dialogues remain clear and natural. This keeps narrative easy to follow. It holds up when a busy orchestral soundtrack plays in the background. It excels in atmospheric immersion. Small background details play cleanly. Wind hums, distant echoes stay audible. This makes the virtual world feel much more believable. The soundstage provides plenty of breathing room.
Conclusion:
The Ceramics MK2 is a set that really grows on you. You just have to work around its daily quirks. I don’t think it compete as a flawless lifestyle accessory. The stock tips are not great. The ANC blocks out basic office hums but struggles against a loud public subway commute. Adjusting the volume via the touch panels is a slow, tedious process. A long press only alters the level by one single increment.
The RoseLink App requires you to choose your priority. You can have high-res LDAC playback or dual-device multi-point connectivity. They cannot run simultaneously.
Look at it strictly from a sound-first perspective. The pure fidelity you get for thirty bucks is crazy. It is an achievement to get Bluetooth 6.0 and an integrated 24-bit DAC at this tier. It easily rivals flagships that are still stuck on older Bluetooth protocols. It grooves past immediate, flashy tricks to prioritize a clean tuning. It offers tight transient agility and a beautifully wide horizontal soundstage. It serves as a highly reliable reminder for the community. You don't need to drop flagship money to find genuine, long-term joy in this hobby.

- Wide horizontal soundstage for a TWS bud.
- Mature, safe and musical tuning profile.
- Spacious charging case clearance allows for third-party tips
- Low latency with 47ms Game Mode.
- Included stock ear tips are not the best and compromise the acoustic seal.
- High-res LDAC playback and multi-point dual-device connectivity cannot run simultaneously.
- The active noise cancellation performance is average
- Steep volume curve and tedious touch stepping for volume adjustments.
- Two true wireless capsules.
- Charging and storage case.
- Three pairs of stock silicone ear tips (S, M, L) (including the tips already on the buds).
- USB-A to USB-C charging cable.
- User manual.

- 1DD configuration with a 10mm titanium-coated dome composite dynamic driver (HR+ Planck structure).
- Integrated 24-bit dedicated DAC chip (113dB SNR).
- Bluetooth 6.0 wireless infrastructure.
- Supported audio codecs: LDAC, AAC, SBC.
- 40dB hybrid active noise cancellation.
Pairing for the tests:
- Stable neutral and warm/neutral source outputs.
- Output volume set between 30% to 50% because the volume curve scales steeply.
- Companion configuration via the RoseLink App.
- Aftermarket wide-bore silicone ear tips.
