Kefine welcomes its first hybrid IEM for the audiophiles, introducing the Kefine Quatio. It’s a quad-driver hybrid set of in-ear monitors that houses a dual dynamic driver setup combined with a dual balanced armature driver setup to deliver a warm, lush, musical sound response. Kefine has equipped the pair with a three-way frequency crossover featuring physical and electronic crossover designs. It comes with three sets of replaceable nozzles, each having a unique sound profile. The pair features high-quality CNC-machined aluminium alloy ear cavities. Kefine bundles the Quatio with a variety of ear tips and a premium stock cable. The cable is a high-purity silver-plated copper cable with modular termination plugs featuring 3.5mm and 4.4mm plugs in the package. Enter into a new level of sonic excellence with Kefine’s latest creation!!

Quad-Driver Hybrid Architecture:-

Kefine Quatio is Kefine’s first foray into the world of Hybrid Driver IEMs. So far, Kefine has developed many successful single-driver IEMs like the Kefine Klean, Kefine Klanar, Kefine Delci, etc. The Quatio is a quad-driver hybrid IEM featuring a 2DD+2BA driver setup. The pair houses a 10mm and an 8mm dynamic driver unit, which are combined with a dual balanced armature driver setup to produce a true high-fidelity sonic experience for the users.

Precisely Designed Three-Way Hybrid Crossover:-

Kefine Quatio features a three-way crossover design. It’s a hybrid crossover design which comprises both physical acoustic tubes and an electronic crossover board. There are three acoustic channels, each goes directly from a 10mm, 8mm and dual BA setup to the ear nozzle. The 10mm DLC diaphragm DD unit produces a high-resolution response across the frequency band. The 8mm dynamic driver adopts a PU+LCP diaphragm, which has been placed to enhance the bass response. The dual BA setup is assigned with task to deliver an enhanced high-frequency band above the 5 kHz frequency range. Together, these four drivers, combined with the accurate crossover design, ensure top-quality sound presentation.

Three Tuning Profiles With Replaceable Nozzles:-

Kefine Quatio is a highly versatile pair of IEMs; the pair features three tuning options easily switchable using the interchangeable nozzle design. The pair comes with three sets of nozzles: Gold Nozzle for a transparent, neutral, more accurate sound, Silver Nozzle for a balanced sound profile, and Black Nozzle for a warm and smooth sound response.

Exclusive Craftsmanship, Proper Comfort:-

Kefine is known for treating its IEMs with superb build quality. The pair features exclusive CNC-machined aluminium alloy ear cavities. The processing time for each pair of housing is more than 30 minutes, and the dimension tolerance is within 0.01mm. Each pair has a well-textured finish as they are finished using advanced polishing and anodising processes. The thickness of Quatio’s metallic housing is just 0.06mm, which minimises the size of the shell and ensures a comfortable fit for most users out there.

High-Quality Stock Cable With Modular Termination Plug Design:-

Kefine Quatio comes with a high-purity silver-plated oxygen-free copper cable. It is a 4-strand cable with a braided structure. Each strand contains 98 wires, totaling to 392 wire cores in total. It ensures lossless sound signal transmission. This cable has swappable termination plug system with 3.5mm and 4.4mm plugs included in the package.

One of the best Bat stories that I've read.
Format: Paperback
Coming off from The Long Halloween, Jeff Loeb and Tim Sale give us the sequel to their popular story tale in which we see Batman go at it with another year long mystery, while also giving us an origin story for the first Robin, Dick Grayson. After reading this book, I have come away having with even more love of the Dark Knight's mythology, while coming to see this as my favorite Batman story that I have read, even if it doesn't stand as well on its own. ON the narrative side of things, Loeb delivers a story fairly similar to the one he gave in The Long Halloween, though I feel this one is a bit more polished than Halloween was. Some have said that the retreading of plot structure have limited the way Loeb's later works are read, but I myself have no problem with it (for the most part), Loeb manages to do enough differently that you don't feel like you're reading the exact same story. The real big negative I'd have to give this graphic novel is that it really doesn't stand as well by itself than if you had read The Long Halloween. While I myself read that story before coming in to this one, I did see many connections that I would assume would through off any newcomers who hadn't read the prior story. But I will say that this is the story that had me invested the most emotionally. Without giving away any spoilers, that last page in the novel gave me such a cathartic experience that I really came to appreciate certain aspects of the Dark Knight's mythology, and how themes of loneliness were touched upon in a very genuine way. Looking at the art for the novel, Sale's work has improved much from The Long Halloween. I always mention in reviews concerning Sale that I was originally not a fan of his art, but after going through his work, you can't help but admire the level skill he manages to put in his drawings. There is a very big noir feeling in this novel (a plus for ) that is just delivered so well that any preferences in art I may have against Sale are put away in admiring the way he plays with lighting in the story. My biggest complaint for the art, which is a more of a personal thing really, is that I do not like the "pixie" costume they gave Robin (which is his default costume that many would associate him with). I have never really liked this costume, probably never will, but again, this is just me. Overall, I would say I really enjoyed the novel and would have to recommend it to any fans of the Batman (although I'd make sure you have read The Long Halloween first). This has come to be one of my most favorited Batman stories I've read, and I hope others will receive the same level of satisfaction that I have.

Great Sequel to Long Halloween
Format: Paperback
This takes all of the great elements of the Long Halloween and keeps it going. The two of those books together is a great story telling. Ticks all the boxes of a great Batman book. If you like this and Long Halloween check out The Penguin show on HBO Max. and if you like The Penguin but haven't read these two books you should since the show pulls a lot of influence from them.
