Every product from Rose Technics has consistently impressed me; I particularly enjoy their iems such as the Starcity 5 Pro, QT9 MK3. They've also produced many others, like tws, the Rose Technics Earfree-i3 suits my taste. Now, they've rebranded under a new name, Roseselsa.
Let's dive into what these TWS buds offer.
This Ceramics X comes in a minimalist. Inside, you'll find:
- Charging case with the earbuds
- Ear tips
- USB charging cable
- Some warranty and instructional papers
While the box looks sleek and minimalist, I preferred unboxing the Eafree I3, which had a protective solid black case for the charging case. However, what truly matters is the sound quality, which we'll discuss next after–The design, build quality, and fit first:
The design of this tws is reminiscent of Samsung Buds, etc, featuring a bean-shaped design that I personally like. The build quality feels solid; despite the name "Ceramics" it's actually made of high-quality plastic that looks quite attractive.
Regarding fit, you need to rotate the buds in your ears from front to back until they fit snugly. This adjustment is crucial for optimal sound quality and isolation. There's also an independent app called Roselink available for further customization on The Appstore.
Now, let's delve into the features and sound of these TWS.
The Ceramics X is equipped with a 1st generation Planck driver unit and features a flagship-grade carbon nanotube diaphragm and a 1.5T dual Tesla magnetic circuit system. These elements work together to reduce distortion and enhance sound density, dynamics, and transient response, delivering HiFi-grade sound quality.
It also includes independent decoding and headphone amplifier modules, paired with the Cadence Tensilica HiFi 5 DSP chip, ensuring authentic audio reproduction with detailed clarity.
This TWS has many features for noise cancelling, including normal, transparent, ANC, and also an independent "Anti-Wind noise" physical structure design that significantly reduces wind noise interference. Unlike regular ANC, the anti-wind feature doesn’t produce a whistling sound when cycling or running in windy environments.
It support LDAC for superior sound quality, perfect for enjoying both passionate pop music and serene classical melodies with high fidelity sound wise like CD quality might.
To optimize this, adjust your device's settings under System > Developer Options > find Bluetooth Audio section > and choose LDAC. and then enable it on Roselink app.
First time i noticed the sound quality, the Ceramics X emphasizes good neutral bright-ish signature with open midrange, crisp trebles, and good clarity, making it less suitable for basshead thack seeks tumpy bass but ideal for vocal clarity and people who like well controlled bass. However, it may be too sharp for those sensitive to treble and sibilance.
There are three sound EQ options on the RoseLink app: Pop, HiFi, and Rock.
Pop is my preferred sound profile. While it lacks the clarity of the other two options, it hits a safe spot. The vocals are good pretty smooth, and the upper and treble are not as bright, since the treble and upper not as push makes the bass feel deeper and puncier than the hifi option. although other instruments such as guitar, violin may not shine as much. This one will suit vocal lovers, especially if your playlist includes a lot of J-pop and K-pop like mine, where sibilance kicks in if the upper midrange is pushed too high.
Hi-fi offers the most clarity, and while I enjoy treble, pushing the upper midrange 'too much' is just not for me. This hi-fi model definitely boosts the upper range a bit too much for my taste. Although reducing the volume helps to tame it somewhat, I still feel the harshness. However, I believe this could be a favorite for some people.
Rock also pushes on the upper frequencies, but not as aggressively as Hifi. It strikes a balance with more noticeable bass than Pop too, and the treble and upper frequencies are less pronounced than in the Hifi mode.
As per teknicalites, all of three has same quality, the stage doesn't narrow and i feel it wider than some of my iems in the same price even, good resolution, and for imaging it is solid. even though its not most dynamic set out there, find they still deliver impressive quality for such an TWS.
Additional info of the Ceramics X
As for battery life, it's pretty solid. It can last up to 10 hours on a single charge and up to 50 hours with the case, which is really efficient.
It's also got an IPX5 rating, so while it's not fully waterproof like IPX7 or IPX8–that you even can use it for swimming, it still can handle low pressure water stream from any angles and rain easily. Great for activities like jogging, cycling, and hitting the gym, both indoors and out.
Plus, it supports dual-device connectivity, so you can switch between devices without any hassle. And with 4 GoerTek silicon crystal microphones and AI-powered noise cancellation, your calls will come through crystal clear.
