Roseselsa Ceramics Ultra Review: The Best Sound Under $50

THE SCORECARD

How the Roseselsa Ceramics Ultra scored

• Sound quality

  8/10

  The stock tuning is clear and dynamic, while the EQ helps me address its bloated mid-bass and forward upper mids.

• Comfort

  8/10

  The compact, light buds fit moderately deep, with a little suction but no strong contact point on my outer ear.

• Security of the fit

  8/10

  They stayed in place for my weight training and running, with surprisingly little body noise.

• Case and battery life

  8/10

  I measured 7 hours and 22 minutes with noise cancelling on, though the case plastic feels cheap.

• Controls

  7.75/10

  The touch controls are highly customizable, but there’s no wearing detection and the long hold takes about 3 seconds.

• Connectivity

  8.5/10

  There are multiple high-resolution codec options, mono single-bud use and multipoint with automatic audio takeover.

• Call quality

  7.5/10

  Calls are usable, but clarity isn’t the best and the earbuds struggle somewhat in my simulated windy-city test.

• App customization and extra features

  8/10

  The Rose Link app includes a useful 10-band EQ, noise-control options and a find-my-buds feature.

• Noise cancelling

  7.25/10

  It handles low-frequency plane noise well but struggles more with higher frequencies and picks up wind outdoors.

• Transparency mode

  7.5/10

  Voices come through clearly, but my own voice sounds somewhat muffled and outdoor wind pickup is worse than with noise cancelling.

The Pros and Cons

How good do the Ceramics Ultra sound?

Sound quality is the standout. The stock tuning is full, clear and direct, with strong sub-bass and mids that bring vocals and instruments forward. Rock and metal sound particularly good to me. The trade-offs are mid-bass that gets a bit bloated, vocals that can turn shouty and treble that’s a little harsh for my ears.

The 10-band EQ makes a real difference. My Picky EQ preset dials down the mid-bass, upper mids and treble while keeping the bass punchy and the instrument detail intact. There’s still a hint of treble harshness to me; reducing it further starts to take away too much. If you’re particularly sensitive to treble, these might not be your buds. Fit can affect what you hear, too.

The soundstage is nothing special, but the vocals and instrument separation are excellent for this price. My sound-quality score of 8 out of 10 reflects what I could get after EQ, not just the stock tuning.

Are they comfortable and secure for exercise?

The included silicone tips worked best for my comfort, sound and noise cancelling. The fit goes moderately deep and creates a little suction, but the buds are light and compact. I could easily wear them all day if needed.

That deeper fit also kept them secure while I was weight training and running, with very little impact noise reaching my ears. This is my experience, not a promise for every ear: if deeper-fitting buds usually bother you, these probably won’t be a great match. They have an IP64 dust- and water-resistance rating.

What battery life and controls do you get?

Roseselsa advertises 11 hours from the buds and 40 hours total with the case, both with noise cancelling off. I’d rather see an advertised figure with it on, so I tested that myself and got 7 hours and 22 minutes at around 40% volume. The case does its job, although it’s a little thick and the plastic feels cheap.

You can assign functions independently to taps and holds on either earbud, including volume, tracks, game mode and noise controls. That freedom is great. The long hold takes about 3 seconds to activate, though, and holding it won’t keep changing the volume. I wouldn’t assign volume to that gesture. There’s also no wearing detection.

How do calls, noise cancelling and transparency hold up?

Call quality is usable rather than a selling point. Clarity could be better, and the buds struggled a bit in my simulated windy-city test. If calls matter more to you, I found the CMF Buds 2 a better option at this price.

Noise cancelling is decent overall. It practically blocked out the low-frequency sound in my plane-noise test, but voices were more of a challenge and higher-frequency sounds got through more easily. Wind is the bigger issue: on a moderately windy day, the microphones can feed it into the earbuds loudly. Wind reduction helps with that pickup, but it provides only light noise cancelling.

Transparency picks up voices clearly, yet my own voice has a blocked-ear quality. Wind pickup is even louder here, to the point that I wouldn’t call transparency usable outdoors with light wind.

How do they compare with other budget earbuds?

The CMF Buds 2 and CMF Buds Pro 2 are better all-rounders for build quality, noise cancelling, transparency and calls. The Tozo NC20 also has stronger noise cancelling and transparency. I’d still choose the Ceramics Ultra for their sound: vocals and instrument separation are where they pull ahead for me.

The Moondrop Space Travel 2 scored just 0.25 lower in my sound-quality comparison and has a flatter stock tuning, so it may suit you better if you want more natural treble without making the same EQ adjustments. For the Ceramics Ultra, the other features are good enough; sound is the reason to pick them.
