UNBOXING:

PHYSICAL ASPECTS:

Construction: For those who followed my review of the Ceramics, you will have noticed that not much has changed since then. The Ceramics X is exactly the same… the only difference is that now, in the X version, some small aesthetic details have been modified in the product design. Both the charging case and the earbuds are made of plastic, and both are very light and compact.

The Ceramics X is very similar to the Earfree i5 in terms of features and technical specifications. Almost everything that the flagship model has is also available in the Ceramics X. In fact, this saved me a lot of time because I will be able to use the basis of the i5 review here for the Ceramics X.

Eartips: These are basic eartips, in sizes XS/S/M/L. I did the review using size M. Here I noticed a difference in relation to the more expensive model – the i5 – the i5’s eartips are better for me, softer, although the Ceramics X’s are also good, I think it’s possible to find the sound of the earphones with the stock eartips.

One difference that makes a lot of sense to me is that the Ceramics X’s nozzle is not oval, that is, it’s rounded. I think that a rounded nozzle is the best shape for inserting the earphones into the ear. For example, the i5 has an oval nozzle, and I thought that the insertion would be better if it had a rounded nozzle (like the i3).

Bluetooth signal connectivity: The pairing is very fast (after the first manual pairing). Just open the case lid and the pairing is done. The signal range was very good, reaching the 10 meters indicated by the company without any interruptions in the music. The signal stability is also very good, I didn’t experience any signal failures or interruptions during use.

Latency test: The Ceramics X has what is called “Game Mode”, which is a low latency feature. I tested the earphone with Game Mode activated and Game Mode deactivated, and in my opinion, in both situations I found the synchronization perfect, with no delays between the image and sound.

Touch controls: This is a very positive point of the Ceramics X (and also of the Ceramics). The Touch area is a very large circle, ideal for you to place your fingertip, so in this regard I think the Ceramics X even surpasses the i5 (and the i3 too). The controls are very responsive, and with each touch you make, the earphone emits a sound to confirm that you made the command (it’s a low and discreet sound, it doesn’t interfere at all).

Multipoint connection: The Ceramics X, like the i5, can connect to two devices simultaneously. You need to enable the function in the App in “Dual Device Connection”. The function does its job very well, I was able to pair it with two smartphones at the same time.

Unfortunately, the Ceramics X doesn’t have the “Auto Pause and Resume” or “In-Ear Detection” function that the Earfree i5 has.

ROSELINK App: The app is available for Android and iOS. The screenshots below are pretty self-explanatory, so I will only comment on what is necessary.

I found the company’s app to be a good app, with a good level of customization of commands and features. However, unlike the i5, the app for the Ceramics X doesn’t have all the same functions available, for example, it doesn’t show the remaining battery time of the charging case, it doesn’t have the “Light” preset (which in my opinion made no difference), and it also doesn’t have the “Auto Pause and Resume” or “In-Ear Detection” function that the Earfree i5 has.

Another observation I have about the app is that I missed a parametric equalizer and also more EQ presets. Another detail is the constant updates of the app by the company… On the one hand this is good, they are always improving, but on the other hand, you need to keep updating it, it gives the feeling that you are using a product that is still a prototype.

ANC and Ambient sound: The Ceramics X has 4 modes: Active Noise Cancellation (ANC), Wind Mode, Transparent Mode, and Normal Mode (which is the off mode).

• Transparent mode is the same as what some companies call “ambient sound”, which consists of opening the microphones to capture sounds from around you. I have to say that this function works well on the Ceramics X.

• I found the ANC to be very good, it can significantly reduce sounds from lower frequencies as well as mid and treble frequencies. Unfortunately, even with the ANC turned on, the earphones pick up a lot of wind noise, the same thing happens with the i5.

• I really liked the Wind Mode, which works to reduce wind noise. I thought the function worked very well when I had a fan pointing at my face. It was the only mode that didn’t pick up wind noise; all the other modes picked up a lot of wind noise. Of course, Wind Mode doesn’t made miracles either.

• Normal mode is the sound from the earphones without any features activated.

Fit and comfort: This is perhaps one of the Ceramics X’s greatest assets. Its fit is different from other TWS that have those stems on the side… this makes the earphones fit well in my ear cups, and I also think they are more comfortable (it’s subjective). Since I consider my ears to be medium/large, I had no problems at all. The stability is very good, the earphones stay well fixed in my ears, and I even think they can be a good alternative for those who want to practice some sport (something that doesn’t require much body movement, like weight training or walking). I found the insertion to be medium to deep, and I found the isolation to be good.

Microphone: In the Mic test, in a quiet environment, I found the quality of the Mic to be very good, although with the addition of a slight background noise. I was able to hear my voice clearly. However, when I tested it with a fan directed at my face, the audio quality was poor, with a lot of added noise.

Accessories: The product comes with a USB-A to USB-C cable.

SOUND ASPECTS:

I understood the sound of the Rosselsa Ceramics X as a Mild V-Shape. It is very similar to the Earfree i5 in terms of tuning, but not so similar when we put the technicalities side by side. Regarding the first Ceramics, I really can’t make a direct comparison, because I didn’t like the sound of that earphone as much. For me, the Ceramics X is much closer to the way I like to hear sound, that is, something more balanced. Now, having the i5 to compare side by side, it is clear that the i5 can indeed be a earphone with better sound performance (in my opinion).

>>I evaluated the Ceramics X with Normal Mode (i.e., turned off) and the HiFi preset.<<

Bass:

Quantitative: As I said above, the tonality of the earphone is well balanced, and the bass level is moderate. These aren’t really earphones for bassheads. I think the i5 even manages to provide a bit more presence and warmth in the bass than the Ceramics X. On the other hand, as I said, the presentation is quite uniform. Sub-bass and mid-bass are in line, that is, I didn’t notice one region standing out more than the other, so both are presented in a homogeneous way. This is a difference I felt from the first Ceramics, where I thought the earphones had a more discreet sub-bass. I didn’t feel any roll-off, the extension is good (in the Ceramics X).

Qualitative: The bass is balanced, linear, natural… it doesn’t stand out in texture and physicality, and this ends up making the earphones not give warmth to the presentation. The impact is quite normal, it doesn’t have much force, but it doesn’t become anemic bass either. The bass is hard to describe, it’s as if they were very good in tonality, but leave a little to be desired in technique. For example, you can listen to electronic music, but anyone who has listened to the genre with earphones that delivered more physicality will certainly feel that “it could have just a little more texture here”. On the other hand, if you enjoy genres that don’t require a lot of bass, the Ceramics X will be a good all-rounder. The bass isn’t boomy, isn’t bloated, and doesn’t invade the mids.

Mids:

Quantitative and qualitative: The mids are very natural, neither recessed nor frontal. I found this to be a very good level, because it fits perfectly with anything you listen to. Vocals, guitars, drums, everything sounds very “correct”, without the sensation of being distant or aggressive. Of course, isn’t the best earphone in terms of airy and details in the mids, I think the i5 itself is superior, however, the Ceramics X is a earphone in a lower price range, and I can say that it has well-defined mids and great balance.

Voices: I think the Ceramics X is a good earphone for both types of voices, whether high or low voices, however, it won’t be excellent with either type. When I say this, it may confuse the mind of a beginner, but it’s like this: if you listen to more sounds with male/low-pitched vocalists, it’s always better to have earphones that deliver more texture and more warmth, because then you’ll have excellent performance for that type of voice… and the same applies to female/high-pitched voices, earphones with more detailing and airy in the upper-mids and treble regions will be able to make this type of vocal deliver the best performance. So, the Ceramics X is that, it’s good for both types, but it’s not excellent for either of them.

Treble:

Quantitative: The Ceramics X’s treble is at a moderate level. With the earphones as a whole, you don’t feel that one frequency is standing out more than the other (of course, this can be directly influenced by the insert and eartip that the person will use). I can say that the earphones don’t cause hearing fatigue because of the treble, so you can rest assured about that. In fact, the i5, which I think has better treble, doesn’t have a problem with this, and the Ceramics X even less so. I didn’t feel any roll-off, and the extension is good.

Qualitative: The treble is balanced, natural, without sibilance, coloration, stridency, or harshness. They have nice definition, and the sparkle is just right. In fact, the Ceramics X’s strengths aren’t airy and detailing. If we compare the i5 and the Ceramics X, for example, I think the i5 would be better suited for listening to Jazz or a genre that needs a touch more quality in the treble… although the Ceramics X isn’t bad, but I agree that the i5 is better. The good thing about the Ceramics X’s treble is that it brings more balance than other TWS on the market… For example, the Buds FE or the Space Travel, I think have less interesting treble (tonally and technically).

Soundstage and Imaging: One of the differences between the Ceramics X and the i5 is precisely the spatiality. In my opinion, the Ceramics X’s soundstage feels smaller than the i5’s. The i5’s presentation has more spatiality, while the Ceramics X only has the basics (which is a good/ok soundstage). So, nothing gets congested on the Ceramics X, the point is that the i5’s soundstage has a greater sense of space. The Galaxy Buds FE itself also has a larger soundstage than the Ceramics X. Tonally, I think the Ceramics X is more balanced than the Buds FE, although the Buds FE manages to have this spatiality a little greater. Imaging also goes the same way, it’s just average, that is, good but not a standout factor.

Super Master EQ: The Ceramics X only has 3 equalization presets, so I’ll briefly comment on what I thought of each one. They are: HiFi, Rock, POP. The HiFi preset is how I described the sound of the earphones in the review and I honestly think it’s the best. I felt that the POP preset basically increased the treble region, but it was very subtle. I felt that the Rock preset changed the mids, the sound became more boxy.

Driver flex test: I didn’t hear any driver flex sound when inserting the earphones into my ears.

Amplification: This is different from wired earphones, this is just to talk about the volume level of the product. I thought that the Ceramics X has a good volume level, I listened here with 80% of the Windows volume scale, more than that for me the sound was already at a level that I consider loud. It’s possible that the issue of better insertion and isolation may have contributed to this volume level being pleasant.
