TL;DR
Hi-Res LDAC meets affordable Chi-Fi practicality. The Roseselsa Ceramics Ultra combines 50dB hybrid ANC, LDAC support, and a punchy 10mm dynamic driver into a light, anatomical shell. It delivers a warm, L-shaped sound signature with 10+ hours of battery life that punches well above its ~$35–$50 price tag.
Been messing around with the Roseselsa Ceramics Ultra for about three weeks now. Roseselsa has been pushing hard into the affordable Chi-Fi market lately, and at around $35 to $50 USD, this set is designed to compete with popular daily drivers like the Moondrop Space Travel and Tanchjim Mino.
What’s in the Box
Design, Build & Ergonomics
Charging case is a compact, rounded box finished in a low-shine, faux-ceramic Dove Gray. It’s easy to slip into a pocket and resists fingerprints well. One small design quirk bugged me slightly: USB-C charging port sits on the bottom of the case rather than the back (it has to lie flat while charging). There's a physical pairing button right next to the USB-C port, and a front LED indicator that shows battery status.
The earbuds look great though. Earbuds feature a stemless, semi-custom shape with a tiny gold-tone screw detail on the outer faceplate holding the housing together. Giving it a cool, camera-lens vibe rather than looking like cheap plastic.
At roughly 6g per earbud, they are very lightweight. Paired with the included NC200 eartips, it is very comfortable. The seal relies on a medium-to-deep insertion that distributes pressure evenly across the ear canal. I’ve worn these through four-hour listening sessions and even while lying on my side without any physical ear fatigue. An IPX4 water-resistance rating handles gym sweat without issue.
Connectivity, ANC & Features
Sound Performance
Roseselsa uses a single 10mm dynamic driver designed to move extra air. With the extra-flexible rubber rim, the driver cone can physically push out 18% farther than usual. Sonic tuning leans toward a warm "L-shaped" signature: big, thumpy bass leads the mix, backed by a smooth, full-bodied midrange that never gets harsh.
Bass
The low end has weight and authority. Driver moves a noticeable amount of air, delivering a deep, physical sub-bass rumble on modern synth, hip-hop, and EDM tracks. Mid-bass slam is punchy and warm. On heavy tracks, the bass can lean slightly boomy rather than lightning-fast, but it rarely bleeds over or smothers the midrange.
Midrange
The midrange is smooth and full-bodied. The crossover and DSP handle the lower-mid transition cleanly, male and female vocals sound rich, natural and intimate rather than thin or distant. There’s zero upper-midrange shoutiness, making acoustic guitars and string sections feel warm and pleasant.
Treble
The top end takes a safe, laid-back approach. Cymbals and high-frequency decay are present but they are smoothed out to avoid sibilance or piercing harshness. The trade-off is that it lacks the razor-sharp micro-detail and "sparkle" you get from multi-driver wired IEMs. However, it keeps the sound fatigue-free for hours.
Soundstage & Gaming
The soundstage offers decent width with a slightly intimate height. Spatial positioning and directional cues are surprisingly accurate. Flipping on the 50ms Game Mode locks lip-sync on YouTube videos and gives reliable positional audio for casual mobile gaming.
Considerations
Verdict
The Roseselsa Ceramics Ultra isn't trying to replace a high-end wired desktop rig, but as an affordable daily driver under $50 USD, it’s a great value proposition. It combines LDAC support, solid wind-resistant ANC, a warm, fatigue-free sound signature, and 10+ hours of single-charge battery life into a lightweight chassis that fits comfortably. It’s an easy recommendation for commutes, workouts, or casual listening on a budget.
If you made it this far, thank you for reading and catch you on the next drop.

Connectivity, ANC & Features
- Bluetooth 6.0 powered by a Tensilica HiFi 5 DSP chip and an independent DAC/amp stage. Beyond standard AAC/SBC, it supports LDAC and LHDC 5.0. Signal stability is solid across my home, work and during walks.
- Touch controls are located on a large circular faceplate on each earbud. It is responsive, and the earbuds emit a subtle, low "game-click" chime to confirm each tap. Multipoint connection lets you pair to two devices at once, though doing so forces the codec back down to standard AAC.
- The 50dB Hybrid ANC is very competent for under fifty bucks. On its "Extreme" preset, it kills low-frequency bus rumbles and air conditioner hum with ease. The Wind Noise Reduction mode is a highlight; it actually works to silence harsh gusts during outdoor walks or when sitting directly in front of a fan. The Transparency Mode amplifies ambient voice chatter cleanly without adding heavy background hiss.
- Battery life is a strong suit. I got around 10 hours per charge on AAC (dropping to ~7 hours on LDAC), with the case providing a total of ~40-45 hours. A 10-minute fast charge nets about 2 hours of juice. To switch ANC modes or turn on the 50ms Low-Latency Gaming Mode, you use the RoseLink app.

Considerations
- RoseLink companion app forces you to enable GPS location access on your phone just to change settings.
- Bottom USB-C port prevents charging it upright.
- Treble-heads looking for ultra-crisp top-end air and clinical resolution will find the top end a bit too smooth and polite.
- Multipoint works but it forces the audio stream down to standard AAC.
