Roseselsa Ceramics X review:

I am an audiophile from sunny South Africa and it is getting ready for winter here now. The Ceramics X was sent tome together with the Earfree i5 earbuds by Roseselsa in turn for my honest opinion. Henry at the company is a very cool guy to deal with and I am really glad I got to know this brand which flew under the radar with me for a very long time. Roseselsa is a sub brand of Rose Technics.

Unboxing:

The Ceramics X sells for $37.99 and my only gripe with the packaging is you have to tear the top part of the box open so you destroy the original packaging. I know this won’t be a problem for most people but I have OCD and like to keep my earphones in their original packaging once I am done reviewing them. You get a small white cardboard box and when you slide the inside box out you get the charging case with earphones inside that greets you first. When you lift that part out you find your pack of ear tips and charging cable. Pretty normal packaging for the price.

Look & Build:

Where the Earfree i5 has a metal charging case the Ceramics X has a hard plastic one. It is similar to the popular ones you get with your EarPods. The earphones themselves are made from hard plastic and has almost the same shape as an in-ear monitor, only difference is no cable with ear hooks. I love the gun metal color mine came in and it looks like beautiful. The Roseselsa logo and the Ceramics X name embossed in gold on the earpieces looks really classy to. The fit for me is a difficult one. Because there is no cable with ear hooks the Ceramics X tends to move around in your ears from time to time especially if you are actively doing something. Same as with Earfree i5 when you have touch controls activated on the app when you want to readjust them in your ears touch controls gets activated and they either turn off or deactivate your ANC. For this I use both the Earfree i5 and Ceramics X with touch disabled at all times. It is not really a problem as I prefer skipping songs and controlling volume from my phone or laptop or any device, I connect wireless earphones to. I just think it is important to note also for guys that like touch controls that they do work. For guys like me with big hands and fingers it is a no touch controls scenario.

Connectivity:

The Ceramics X with it’s impressive Bluetooth 5.3 and awesome codecs and low latency makes these an absolute steel at the price if wireless connectivity is your main point for buying TWS earphones. They are similar built to my Sennheiser Momentum wireless earphones, sound better and cost a lot less. I connected the Ceramics to all my Bluetooth devices like phone, Dap, laptop etc. Again, if I have to measure the connectivity to Earfree i5 I experienced over 20 meters connections with no cut outs but with Ceramics I did experience cut outs at not even 15 meters. Please also note I am measuring it against the Earfree i5 which costs a lot more. The app for me is such a gem that I would not buy the Ceramics X if there was no app. You get software updates for your earphones via the app and the software works without any glitches. As I am an audiophile that does not use an equalizer a lot the 4 settings equalizer is enough for me and I listen mostly on the HiFi setting with Full ANC on. I do prefer the Earfree i5 for making calls and tested the 4 mics on the Ceramics and they work really well. I just use the Earfree i5 more because I like the fit better.

Sound:

Roseselsa claims a first-generation Planck driver causes you to Experience HiFi grade sound quality on TWS earbuds. I will put that to the test. For a first impression I put on some EDM Dance music as I wanted to listen how the bass sounds and also how the driver preforms under high volume as that was negative for me on the Earfree i5. Straight to my TIDAL EDM folder and there is song called Drip (feat. Eliza Legzdina) and it starts with a nice deep bass line and the whole song has a really nice Ballance between Midbass slam and sub bass rumple. These Ceramics X are in your face man. They immediately announce to you that they are in the building with what sounds to me like a U-shape sound signature with great, fast bass slam and rumble with some bright highs. Another ten EDM songs later and I had my verdict and if you are an EDM Fan and you are also interested in the highs in EDM Music then this for you. We are very use to bass head earphones where the focus is solely on the bass and not much anything else that this approach is refreshing.

I wanted to explore the Planck driver further and opted for my Audiophile folder. To build on the nice bass I heard with the EDM Music I switched to Inertia Creep by Massive Attack which is my go-to song for bass and man did the Ceramics X impress me. That bass slam is something else.  I noticed something with the bass and I don’t know if it is something I have never listened for before or if I just picked it up with the Ceramics X but you can hear the hollowness inside and instrument like a Cello. I heard more sub-bass than mid-bass and I prefer sub over mid bass so for me it is win with the bass. It is fast like a planar bass but also goes deeper. There is a song I have that I mentioned in previous reviews which has very big Chinese drums called Poem of Chinese Drum- Hok Man Yim and boy did the sound become explosive. Those big drum hits sounded like cannon fire.

The mids sounded thin and recessed as I am very used to Sara K’s voice and it did not have so much authority as I have heard on other earphones. It is as if the mids is saying to the treble and bass “go ahead guys, its your time to shine”.  All my favorite male singers like Mark Knopfler, Chris Jones, David Gilmour and Ryan Adams all sounded a bit further back in the mix.

The highs are delivered with an in your face bright but not sibilant or ear fatiguing as I wore the Ceramics X for hours on end without any fatigue. Just be reasonable to yourself and don’t go blowing your ears out as these go hard volume wise. Where I complained about the low volume on the Earfree i5, the Ceramic X hits volume out the park and the amp chip has enough power to drive the driver to loud levels with authority and without distortion. All instruments in the higher ranges like flutes, high notes of the piano and guitar sounded phenomenal. Violens were another instrument that really stood out and together with the thick bass on Lindsey Stirling- Crystalize you are taken very high up in the audio spectrum.

The soundstage is more narrow than wide and I never experienced the sound stage expanding wider than the space between my ears. The driver is very fast and almost sound planar like and this helps the transients a lot. Nonmatter if it was fast classical transients or electrical transients like on Robots in Motion by Philter the Ceramics just kept keeping up and reproducing perfectly and with composure. Even though the soundstage was not that wide I do have to mention that the instrument separation is really good and each instrument is clearly distinguishable in time and space. If you are an audiophile, I am pretty sure the sound will appeal to you. No matter what genre I threw at the Ceramics X it just kept coming back with this in-your-face type of sound on all genres. Obviously, I won’t use these for Jazz, Classical and Blues but for everything else these can replace most in-ears if you are looking for just one pair of TWS to replace all your wired stuff. The sound is really that good.

Wit the nozzles being round and longer than the Earfree i5 it does make tip rolling easier on the Ceramics X. I however was so happy with the stock tips that I did not fiddle around a lot with tips. I do want to state that I found these little no-name wide bore gems which I will do a little mini feature on later that really smoothed the sound out a bit. With these tips I also do most of my listening on the Ceramics X. If you plan on using these for listening while doing chores and you are scared that they would fall out of your ears and into something like water at least you can feel comfortable knowing there is some waterproof in the Ceramics X.  

I use the Earfree i5 for all my calls when I am at home not because they are better for calls than the Ceramics X, but because I am move around better with the Earfree i5’s in my ears than the Ceramics X. The four GoerTek Crystal Silicone mics are crystal clear and if great calls functionality is one of your presets for buying a pair of TWS earphones then the Ceramics X won’t disappoint. In gaming mode, the Lighting Latency reductions worked pretty well and while playing Call of Duty mobile I did not experience any latency. On the contrary with the Planck driver being very fast the Ceramics X coped very well with incoming footsteps and gun shots. If you are a first-person gamer not using a headset then these will suit you very well as the battery life is phenomenal for long gaming sessions and the sound is also fatigue free. I hope I get a lot more to do with Roseselsa and their products.

Conclusion:

The Ceramics X set the bar pretty high for me in sound qualities for TWS Earphones and from here on all TWS Earphones sound I review, I will compare to the Ceramics X. I think more people should know about Roseselsa. The two products I have had so far from them is top notch and great quality vs price. The Ceramics X blows away the more expensive Earfree i5 with sound and a lot of other wired In-ear monitors in its price category for that matter. If sound quality is your main goal get the Ceramics X. If you are an audiophile new to TWS then get these. You won’t be disappointed with sound quality. If you are a music lover without a big budget and you want to get a decent pair of TWS Earphones, then get these. If you want to upgrade from the buds you got with your phone, then get these. They are worth it.
