✅ Pros: Ridiculous price-to-performance, highly resolving sound, fantastic layering, unusually wide and tall staging, excellent instrument separation, tiny size, superb comfort, strong ANC for the price, LDAC and LHDC 5.0 support, Bluetooth 6.0, IP64 protection, useful ROSELINK app, responsive custom 10-band EQ, dual-device connection, Game Mode, Find Device, and strong battery specifications.

⛔ Cons: No wear-detection sensor, so removing an earbud does not automatically pause playback. Call quality is only average, with multiple people telling me my voice sounded distant. Stock tuning is decent, but it doesn’t reveal everything these earbuds are capable of until you dig into ROSELINK and EQ. ANC is very good for the money but does not reach premium Bose-level isolation.

🦖 Disclosure

ROSESELSA generously provided the CERAMICS ULTRA for this review.

A huge thank you to Jesse and the entire ROSESELSA team for your trust, support, and partnership with GearZilla Reviews.

That trust means a lot to me.

It also doesn’t buy a positive review.

Gear provided to GearZilla Reviews doesn’t guarantee favorable coverage, a particular score, protection from criticism, or any influence over my conclusions.

I want to understand what the product was designed to do.

I want to hear it before I start trying to change anything.

I want to live with it long enough that the specifications stop being the story.

And eventually, I want to answer the question that matters most to me:

Does this thing help me enjoy the music I already love in a new way?

With the CERAMICS ULTRA?

Absolutely.

---

🤯 Under $50? Seriously?

The first thing you need to understand about the CERAMICS ULTRA is the price.

ROSESELSA currently lists them at $46.99, with an even lower sale price shown at the time of this review.

And somehow you’re getting:

Bluetooth 6.0.

Hybrid ANC.

LDAC.

LHDC 5.0.

IP64.

Four microphones.

Independent DAC and amplifier architecture.

Cadence Tensilica HiFi 5 DSP.

Game Mode.

Dual-device connectivity.

Find Device.

Custom 10-band EQ.

And up to 11 hours per charge with 40 hours total from the case.

That sounds ridiculous.

But the feature list isn’t even the reason these impressed me.

The sound is.

---

📦 First Impression: Where Did the Rest of Them Go?

These things are tiny.

Like:

Where-is-the-rest-of-the-product tiny.

The entire charging case is smaller than some individually wrapped eyeglass cleaning wipes I’ve carried around.

I kept looking at it thinking:

Are there earbuds, batteries, charging hardware, and all that technology inside this?

It disappears into a pocket.

The earbuds disappear into my ears.

And somehow the soundstage does the exact opposite.

It gets huge.

---

🎧 Review Setup

Every GearZilla review starts with the same idea.

Listen first. Figure out the story later.

I used the CERAMICS ULTRA for roughly two weeks of daily listening.

My testing included:

• Stock tuning
• ROSELINK Super Master EQ presets
• Custom 10-band EQ
• ANC
• Ambient mode
• LDAC from my HiBy R4
• Dual-device connectivity
• Game Mode
• Find Device
• Phone calls
• Everyday use
• Lots of different genres and recording styles

Stock tuning?

Good.

Clean.

Pleasant.

Perfectly usable.

But nothing about it immediately screamed:

There is a monster hiding in here.

Then I opened ROSELINK.

Then I started listening more deeply to the recordings.

Then I paired them with the HiBy R4 over LDAC.

And suddenly:

Ohhhhh.

There you are.

---

🧬 KAIJU DNA SCAN

Every monster leaves behind a genetic signature.

Here’s what this one looks like.

K • Kill Shot

The CERAMICS ULTRA’s greatest weapon is:

Massive resolution and separation from something this tiny and inexpensive.

That’s the thing I couldn’t get over.

You can expect an inexpensive TWS to be convenient.

You can expect decent bass.

Maybe decent ANC.

Maybe a surprisingly usable app.

But this?

Layers.

Space.

Resolution.

Separation.

The CERAMICS ULTRA kept revealing information buried inside recordings.

And because the presentation is so spatial, those details aren’t simply dumped into one crowded blob.

They have somewhere to exist.

That’s the kill shot.

A • Anatomy

ROSESELSA packs an absurd amount of hardware into this tiny package.

You’re getting:

• HR+ Planck driver
• Dual-material composite diaphragm
• Carbon nano dome
• Independent DAC and amplifier architecture
• Cadence Tensilica HiFi 5 DSP
• Bluetooth 6.0
• LDAC
• LHDC 5.0
• Hybrid ANC
• Four MEMS microphones
• IP64 protection
• Dual-device connectivity
• Game Mode
• Find Device
• ROSELINK app support
• Custom 10-band EQ
• Up to 11 hours per charge
• Up to 40 hours total with the case

All inside one of the smallest ANC TWS packages I’ve personally encountered.

I • Impact

The impact comes from:

Resolution.

Not just treble.

Not fake detail.

Actual separation between layers.

Backing vocals remain identifiable.

Percussion stays distinct.

Reverb trails continue behind the main performance.

Guitars don’t disappear the moment vocals enter.

Little production elements remain suspended within the larger image.

The sound has structure.

And that structure gives complex music room to breathe.

J • Joy

The joy is discovering how much more these can do than the price suggests.

Put them in.

They’re comfortable.

Connect.

Listen.

Open ROSELINK.

Start tweaking.

Try another EQ.

Pair them with LDAC.

Hear a layer you hadn’t noticed.

Go back to another song.

Hear another one.

That became the fun.

The CERAMICS ULTRA invites exploration.

And for GearZilla?

That’s basically catnip.

U • Unleashed

ROSELINK is where the CERAMICS ULTRA gets unleashed.

The stock profile is fine.

But the app gives you Super Master EQ profiles, including:

• Classic Style
• Pop
• HiFi
• Rock

And then:

Custom 10-band EQ.

That’s where things get serious.

Want more bass?

Add it.

Want more vocal presence?

Adjust.

Want more air?

Go.

Want to soften something?

Do it.

The driver responds remarkably well.

That matters because this isn’t EQ rescuing a fundamentally bad product.

You’re reshaping a technically capable one.

That’s the CERAMICS ULTRA unleashed.

---

🎼 Sound

The easiest way I can describe the CERAMICS ULTRA is:

Resolving, spacious, layered, and shockingly organized.

What impressed me most wasn’t one particular frequency range.

It was how everything worked together.

The sound feels much larger than the earbuds.

There’s width.

There’s height.

There’s depth through layering.

And because instrument separation remains strong, that space doesn’t become vague.

It stays organized.

That is a huge accomplishment in a TWS this inexpensive.

---

🥁 Bass

The CERAMICS ULTRA can absolutely produce satisfying bass.

But bass isn’t the entire identity.

The stock tuning keeps things controlled enough that low frequencies don’t simply swallow all the detail above them.

And if you want more?

ROSELINK.

Add some.

The custom EQ gives you enough control to push weight and impact while preserving the separation that makes the CERAMICS ULTRA special.

That flexibility is a big deal.

Start clean.

Then season to taste.

---

🎤 Midrange & Vocals

Vocals benefit enormously from the separation.

Instead of being jammed into the rest of the mix, singers have room around them.

That space makes vocal textures easier to follow.

Backing harmonies stay clearer.

Multiple voices remain easier to distinguish.

And the CERAMICS ULTRA doesn’t need to sacrifice the surrounding instrumentation just to make the vocal intelligible.

The singer gets space.

The band keeps theirs.

That’s exactly how I like it.

---

🎯 Instrument Separation

This may be the strongest sonic achievement of the CERAMICS ULTRA.

The separation is fantastic.

Busy music?

No problem.

Multiple percussion layers?

Still identifiable.

Guitars.

Keys.

Bass.

Backing vocals.

Ambient effects.

Production details.

Everything gets its own little pocket.

That doesn’t mean the performance becomes disconnected.

It means you can follow individual pieces without losing the whole.

And that’s what kept producing those:

Wait… has that always been there?

moments.

I love that.

---

🏟️ Soundstage & Imaging

The stage is:

Wide.

But width alone isn’t what makes it special.

There’s also:

Height.

That gives the CERAMICS ULTRA a much more spatial character than I expected.

Vocals can occupy one layer.

Percussion another.

Additional information can stretch outward or appear above the center image.

And because the separation is excellent, all that space remains coherent.

Wide.

Tall.

Layered.

Spatial.

That’s the soundstage story.

---

✨ Treble & Air

There’s enough upper-frequency energy to keep the presentation open and resolving.

That clarity helps create the sense of air and separation.

But the great thing is:

You’re not trapped.

If the stock balance feels a little too energetic?

Open ROSELINK.

Adjust it.

Smooth it.

Warm it.

Change the presentation toward your preferences.

The technical foundation remains strong.

That makes tweaking much more rewarding.

---

📱 ROSELINK: The Secret Weapon

The app deserves its own section.

Because it changes this product.

ROSELINK gives you:

• Super Master EQ profiles
• Classic
• Pop
• HiFi
• Rock
• Custom 10-band EQ
• ANC controls
• Dual-device functionality
• Game Mode
• Find Device

And importantly:

The EQ actually works.

You hear the changes.

You feel the tonal balance move.

You’re not staring at sliders wondering whether you imagined the difference.

That makes the CERAMICS ULTRA incredibly fun to explore.

---

🔊 LDAC + HiBy R4

Then I paired the CERAMICS ULTRA with my HiBy R4 using LDAC.

Fantastic pairing.

That gave the resolution and separation even more opportunity to shine.

Again, Bluetooth is still Bluetooth.

I’m not pretending the cable disappeared from physics.

But with a capable source and LDAC?

The CERAMICS ULTRA gave me more than enough clarity and detail to make serious listening enjoyable.

And for something under $50?

That’s nuts.

---

🌊 ANC: Slip Into Your Own World

The ANC significantly exceeds what I expect from this price class.

Is it Bose QuietComfort Ultra II?

No.

Bose can still almost erase the outside world… but for $200+ more.

The CERAMICS ULTRA does something slightly different.

It pushes the world away.

Traffic.

HVAC.

General background noise.

Environmental clutter.

It gets reduced enough that music becomes the thing your brain wants to focus on.

That’s excellent everyday ANC.

I didn’t test them on an airplane, so I won’t pretend I did.

But based on their performance with continuous environmental noise?

I’d absolutely bring them on my next flight.

---

📞 Call Quality: The Monster Has a Weak Spot

Here’s where the price shows.

The CERAMICS ULTRA uses four microphones and plenty of processing.

But in my actual calls?

Voice quality was only average.

Everyone could understand me.

But I received essentially the same feedback repeatedly:

You sound distant.

Not garbled.

Not broken.

Not unusable.

Just farther away than I actually was.

For occasional calls?

Fine.

For someone who spends all day on Teams or conference calls?

I’d look elsewhere.

---

⏸️ My Other Gripe: No Wear Detection

This one annoyed me.

The CERAMICS ULTRA does not automatically pause when you remove an earbud.

Take one out?

Music keeps playing.

Put it back?

Nothing automatically resumes because nothing paused.

Once you’ve lived with automatic wear detection, it becomes one of those invisible convenience features.

Until it disappears.

And then suddenly:

You really notice it.

I would love to see it added.

Absolutely.

Does it ruin the CERAMICS ULTRA?

Not remotely.

But it does cost them points.

---

🎮 Game Mode

ROSESELSA also includes Game Mode, with a claimed full-link latency as low as 54ms when used with LHDC 5.0.

I didn’t perform instrumented latency testing.

But having a dedicated mode adds another layer of versatility.

Music.

Travel.

Work.

Gaming.

Again:

Under $50?

Come on.

---

🔄 Dual-Device Connection

Dual-device connection is another quiet win.

It makes everyday use easier.

And good wireless technology should disappear into your routine.

You shouldn’t have to perform a Bluetooth ritual every time you change devices.

The CERAMICS ULTRA gets that right.

---

📍 Find Device

ROSELINK includes a Find Device feature.

And considering how tiny these things are?

Excellent decision.

Because they’re absolutely small enough to fall between the couch cushions and form their own tiny civilization.

---

🔋 Battery & Daily Practicality

ROSESELSA rates them for:

Up to 11 hours per charge.

Up to 40 hours total with the case.

I didn’t run an 11-hour stopwatch test.

What matters more to me is that battery anxiety never became part of my two-week experience.

Grab them.

Listen.

Put them away.

Repeat.

That’s exactly how everyday wireless gear should work.

---

💰 Value

This is where things get silly.

You’re getting:

• Excellent resolution
• Fantastic instrument separation
• Wide and tall staging
• Strong layering
• Hybrid ANC
• Bluetooth 6.0
• LDAC
• LHDC 5.0
• IP64
• Custom 10-band EQ
• Dual-device connectivity
• Game Mode
• Find Device
• Strong battery specifications
• Incredible comfort
• Microscopic size

For under $50.

But value isn’t just a feature checklist.

The real value is:

I actually wanted to keep using them.

That’s always the test.

---

👹 Who Is This For?

The CERAMICS ULTRA makes enormous sense for listeners who want:

Resolution.

Space.

Layers.

Wireless convenience.

ANC.

EQ flexibility.

And ridiculous value.

It’s especially interesting for audiophiles who want an inexpensive wireless option without completely giving up the things they care about in serious audio.

Do new details in familiar recordings make you smile?

This one is for you.

---

🦖 GearZilla Score

☁️ Comfort: 5.0/5

Ridiculously easy to wear for extended periods. Tiny shells, virtually no fatigue during my testing and one of the smallest TWS packages I’ve encountered.

🔬 Resolution: 5.0/5

The biggest surprise. Layers remain easy to follow and small details survive busy mixes far better than I expected at this price.

🌌 Separation & Imaging: 5.0/5

Excellent organization, strong instrument distinction and a presentation that feels both wide and tall.

🎼 Sound Quality: 4.8/5

Technically excellent and highly enjoyable, especially once ROSELINK unlocks the tuning. Stock sound is good, but the app reveals the real potential.

📱 Tuning Flexibility: 5.0/5

The Super Master presets are useful, and the custom 10-band EQ is fantastic. This is one of the CERAMICS ULTRA’s biggest strengths.

🌊 ANC: 4.5/5

Way better than I expected for the price. It won’t replace Bose Ultra for maximum isolation, but it does an excellent job pushing everyday noise far enough away to let the music take over.

📞 Call Quality: 3.5/5

Usable, but multiple people described my voice as distant. Fine for occasional calls, not a standout.

⚡ Everyday Usability: 4.5/5

Dual-device connection, Game Mode, Find Device, great comfort and tiny size are fantastic. The missing wear-detection sensor is the one obvious convenience feature I kept wanting.

💰 Value: 5.0/5

This is where the CERAMICS ULTRA becomes ridiculous. The amount of sound quality, functionality and flexibility packed into this price is exceptional.

🦖 Overall GearZilla Rating: 4.5/5 • A-Class Kaiju

🦖 Final Roar

The ROSESELSA CERAMICS ULTRA surprised the hell out of me.

I expected:

Good value.

Lots of features.

Decent ANC.

A respectable, inexpensive TWS.

I did not expect this sound.

I didn’t expect this much resolution.

I didn’t expect layers behind layers.

I didn’t expect instrument separation this strong.

And I definitely didn’t expect a stage this:

Wide.

Tall.

Spatial.

from something small enough to disappear into my pocket.

Then ROSELINK opened the door even farther.

The 10-band EQ works.

LDAC from my HiBy R4 sounded fantastic.

ANC significantly exceeded expectations.

Comfort was basically effortless.

And after two weeks?

I kept reaching for them.

That tells me more than the specification sheet ever could.

Are they perfect?

No.

The lack of automatic wear detection is annoying.

Call quality is only average.

Those are real shortcomings.

And they’re exactly why this lands at 4.5 instead of 5.0.

But zoom out and look at what ROSESELSA accomplished.

Under $50 should not sound this resolving.

Under $50 should not feel this spacious.

Under $50 should not give you this much control.

And yet:

Here we are.

🏆 GearZilla Price-to-Performance Champion
