Disclosure: I’d like to thank Roseselsa for providing me with the Ceramics X for this review. All thoughts and opinions are my own, and Roseselsa had no say or input on the contents of this review.

The Roseselsa Ceramics X costs $45, which honestly made me skeptical before testing them. Rose Technics claims these budget TWS earbuds deliver performance that challenges much more expensive options, but I’ve heard similar promises before that didn’t quite pan out.

The spec sheet reads like something from a much pricier product. Hybrid ANC with 55dB noise reduction, four GoerTek silicon crystal microphones handling AI-powered noise cancellation, and a gaming mode dropping latency to 54ms. Add IPX5 water resistance for workouts and that V-shaped sound signature many listeners prefer, and you start wondering what compromises Rose Technics made to hit this price point.

That’s exactly what I set out to discover. Do these earbuds actually deliver on their ambitious promises, or do the budget constraints show up in ways that matter? Let’s find out if the Ceramics X truly deserves consideration as your next pair of TWS earbuds.

• Roseselsa Ceramics X
• Three sets of eartips (S, M, L)
• USB-C to USB-A charging cable
• Manual

The first thing you notice about the Ceramics X is how light they feel in your hand. At 4.5g per earbud, they’re among the lighter TWS options I’ve tested recently. The polycarbonate construction feels solid without being heavy, and that compact, rounded shape immediately sets them apart from the stem-heavy designs dominating the market.

Rose Technics claims they tested over 2000 ear canal profiles across 70 design iterations to nail the ergonomics. Whether that’s marketing speak or not, the results speak for themselves. I wore these for 4-hour listening sessions without the usual pressure points or fatigue that plague many IEMs.

The charging case has a glossy metallic finish that looks more expensive than the price suggests, though the hinge does feel a bit flimsy when opening and closing. It’s not a deal-breaker, but you’ll want to be gentle with it.

Here’s where Roseselsa made a smart choice: rounded nozzles instead of oval ones. I find these much easier to insert properly, and at roughly 3.5mm in length, they create a good seal without going too deep into your ear canal.

One quirky thing I noticed – the included ear tips run large. What they label as XS feels more like a standard small, and the small feels like medium.

For casual listening and walking around, these stay put remarkably well. The IPX5 rating means sweat and light rain won’t be issues, and I had no problems during gym sessions involving weights or treadmill work.

More intense activities like running might cause some shifting since there are no ear hooks or wings for extra security. Not a huge issue for most users, but worth noting if you’re primarily buying these for high-intensity workouts.

The circular touch panels are generously sized and respond consistently to different tap patterns:

• Single tap: Volume up (right) or down (left)
• Double-tap: Play/pause on either side
• Triple tap: Previous track (left) or next track (right)
• Quadruple tap: Game Mode (left) or Voice Assistant (right)
• 3-second press: Toggle noise cancellation modes

Each tap gives you subtle audio feedback without interrupting your music. The sensitivity feels well-calibrated – responsive enough to register intentional touches but not so sensitive that brushing against them accidentally triggers commands. After a few days of use, the control scheme becomes second nature.

Rose Technics didn’t stop at impressive hardware specs. The ROSELINK app and software features reveal whether Ceramics X can execute on its ambitious feature list.

ROSELINK App: Modes and Customization

The ROSELINK app works on both iOS and Android with a clean interface that gets the job done. You get three sound presets—HiFi, Pop, and Rock—which provide decent variety for different listening preferences. The app lacks a parametric equalizer, though, which feels like a missed opportunity at this price point, where users might want more control over their sound signature. Rose does seem committed to improving the experience, with frequent app updates showing up regularly.

ANC Performance and Modes

Here’s where things get interesting. The Hybrid ANC claims 55dB noise reduction across a 4000Hz range, supposedly eliminating 98.7% of daily noise. That’s marketing speak, but the ANC does work better than expected for budget earbuds. You get four modes to choose from: the main ANC mode, Wind Mode that targets outdoor interference, Transparency Mode for environmental awareness, and Normal Mode without processing.

The Wind Mode deserves special mention since it actually addresses a real problem with cheaper earbuds during outdoor use. Most budget options struggle with wind noise, so having a dedicated mode shows Rose Technics considered real-world usage scenarios.

Game Mode Reality Check

Game Mode supposedly drops latency to 54ms, but I found the improvement minimal for casual gaming. Competitive gaming still shows noticeable lag, so don’t expect these to replace dedicated gaming headsets. The feature works as advertised technically, but the practical benefits are limited.

Dual Device Connection Limitations

The dual device pairing actually proved useful when switching between my phone and laptop. There’s a catch, though—this feature doesn’t work with LDAC enabled, which means you have to choose between high-quality audio and convenience. That’s a reasonable compromise given the price, but worth knowing upfront.

Sound quality determines whether these earbuds justify their ambitious spec sheet, and thankfully, the Ceramics X delivers audio performance that genuinely surprised me during extended testing sessions.

HiFi Mode: Balanced and Natural Tuning

HiFi mode became my go-to preset after several days of testing. Despite maintaining a mild V-shaped signature, it offers the most coherent sound among the three options. The bass hits with punch without drowning out other frequencies, while the treble sparkles without becoming harsh. Female vocals particularly benefit from the brighter treble response, gaining energy and clarity in the upper mids. Some listeners might initially find this mode a touch bright, but it rewards detailed listening across most genres I threw at it.

Pop Mode: Vocal Emphasis and Mid Clarity

Pop mode confused me at first – the name suggests one thing, but the tuning does another. This preset actually pulls midrange frequencies forward while dialing back bass and treble. Vocals become the star of the show, which works well for acoustic tracks and podcasts. The naming feels off, though, since it boosts sub-bass while reducing upper mids and treble, creating a sound that doesn’t match what most people expect from “Pop” tuning.

Rock Mode: Bass and Treble Boost

Rock mode cranks up both bass and treble for a more aggressive, energetic presentation. Vocals get pushed back in the mix, which makes sense for genres where the rhythm section drives the music. I found this setting perfect for electronic music and hip-hop, where impact matters more than vocal nuance, though it can make some tracks feel overly dramatic.

Bass Performance: Sub-Bass and Slam

The low-end impressed me more than expected at this price point. Sub-bass digs deep with a satisfying rumble that really shows up in electronic music. Mid-bass stays controlled and doesn’t muddy the midrange, maintaining clear separation between frequency ranges. That said, the bass doesn’t quite have the aggression and texture you’d find in higher-end models – it’s clean and present, but not particularly exciting.

Mids and Vocals: Presence and Realism

Midrange performance varies depending on what you’re listening to. Male vocals sound warm and present, though the V-shaped tuning occasionally pushes them back slightly. Female vocals fare better overall, especially in HiFi mode, where they gain energy and clarity. Instrument separation caught my attention during complex tracks – individual elements remain distinct without sounding artificially isolated.

Treble and Soundstage: Detail and Airiness

The treble response brings good detail and extension up to around 13kHz. Cymbals and hi-hats cut through with crisp definition, though I noticed occasional harshness at higher volume levels. The soundstage feels relatively intimate – not particularly wide but with decent vertical space. Imaging handles most material well, though really complex passages can challenge its spatial presentation.

The Roseselsa Ceramics X spent several weeks as my daily earbuds, and I keep coming back to one thought: how did they pack this much performance into a $48 product? These earbuds challenge what we expect from budget TWS options in ways that genuinely surprised me.

That battery life alone justifies the price. Ten hours from the earbuds plus another 40 from the case means you’re not constantly hunting for charging cables. The 10-minute quick charge delivering 10 hours of playback has saved me more times than I can count when rushing out the door.

HiFi mode became my go-to setting, offering that balanced sound with enough sparkle to keep things interesting. Sure, the lack of a parametric EQ feels limiting, and yes, the treble can get a bit sharp at higher volumes. But these feel like minor complaints when the overall package delivers this well.

What impressed me most was how these earbuds never felt cheap during extended use. The 4.2g weight disappears after a few minutes, and I never worried about them falling out during workouts. That IPX5 rating actually works – I tested it.

The Ceramics X won’t satisfy audiophiles seeking reference-quality sound, but that’s not what these are for. If you want reliable daily drivers that sound good, last all day, and won’t break the bank, these deserve serious consideration. Rose Technics found that sweet spot where price meets performance, and the result is one of the better budget options I’ve tested lately.

At under $50, the Ceramics X makes it hard to recommend spending significantly more unless you have very specific needs they don’t address.
