OC Studio 2020 flagship series' new masterpiece, Caelus, represents hope and future, and is named after the Greek primordial god of the sky! The goal is to create high-performance copper wire that rivals silver wire in sound quality, carefully selecting different approved materials and using Litz Structure T2 construction, combined with top-of-the-line audio-grade solder to achieve the ideal sound! This time, two colors are available: Elephant Gray and Earth Brown! Matching with OC original accessories highlights the high-quality texture!
When we connect Caelus to headphones, we immediately feel a large amount of detail and a broad soundstage that is like the sky. The level of detail is not inferior to silver wire, and the soundstage is wide with high separation. The instruments and vocals each play their role without entangling each other, instead, they perfectly blend together, making the sound full and complete! The sound of the instruments is dense and with excellent shape, which is amazing! The vocals are more present and closer, making it easier to listen to. The performance of the low frequencies is also admirable, with appropriate volume that can deeply immerse you and bring a pleasant impact! The overall sound is more moderate and not as bright, but it presents the details and layers with deep and complete skill. In terms of quality, it is definitely on par with silver wire! In terms of sound, it is definitely a great value and a cable that is worth collecting!

ACTUAL Customer feedback
FINAL E4000: I've been buying from OC since the first UE generation UE+. Since the appearance of MK4, I have liked OC's pure copper wire. MK5 is also very good. This time, I directly aimed for the OC Caelus within my budget. The level of information in the sound is that of high-end wires. I personally like the sound of dynamic drivers. This wire interprets the low frequency of dynamic drivers beautifully. The energetic feeling spreads out like ripples. The low frequency is very textured, and there are rich details in a comfortable atmosphere. It is easy to listen to for a long time. Good copper wire is really "plain and boring" like this (mistaken) (Used with FINAL E4000, so you can experience its strength without expensive headphones. (February 9, 2020) SONY IER-M9: Compared to the original, the low frequency is much fuller and elastic in the current RUN line. The high frequency is bright and no longer piercing. Looking forward to the performance after RUN IN~ (February 20, 2020) SONY MDR-Z1R (earmuffs): Compared with the original, the human voice is more three-dimensional and less rough. The high frequency is well extended and not harsh. This wire interprets the unique low frequency of Z1R better and makes it more immersive. (March 10, 2020) SENNHEISER-HD800: When I put it on and listened, I was surprised by the open sound field performance. The separation and hierarchy have been further improved, clear and distinct, without losing the precision of instrument positioning. The mid-range performance is not too rich and full-bodied, but rather restrained and neutral, with a hint of warmth. The low frequency performance is full of energy, the sound is clear and the rebound is powerful. The performance on drums is very good, and the air feeling of the drum skin vibration and dive is impressive. If you want better low frequency and sound field performance, this wire would be a good choice. (March 9, 2020) Westone UM Pro 50 New: Good seller with good service and fast delivery! The product is really good, worth coming back to this seller! When I first tried it, the high, medium, and low frequency sounds were independent and clear, and the vocals and instruments were distinct yet integrated. It is a good wire that you will fall in love with at first use! (March 27, 2020) FiiO FH7: It's not bad. It makes the annoying high frequency spikes smoother, the sound field bigger, and the instrument positioning more accurate. I hope there will be other new headphone wires in the future for me to try! (October 12, 2020) iBasso SR2: I just opened it and the low frequency is moderate and excellent in diving. The mid-range is full and the vocals are slightly forward. Although it is a copper wire, it has a silver wire-like high frequency. Compared with the original headphone wire, the instrument separation, detail, and overall sound field are significantly better, and it is more durable. (October 22, 2020) Audio-Technica IM03: As an old user (from Zeus SC, UE+ to UEX), I feel that the manufacturing quality and detail processing have greatly improved with Caelus. Sound performance: The low frequency texture is very good, moderate in diving, and the quantity is also moderate. It brings back the slightly less low frequency of UEX. The mid-range: The sweetness of the vocals is very good, although it is not as close to the ear, but when a male and female singer sings, their voices can be easily distinguished, and there is almost no sibilance. The high frequency is completely comparable to UEX, with excellent extension and less harshness. The performance of the sound field: The horizontal extension is quite good, and you can hear instrument details that were not noticed before, especially the restoration of stringed instruments. It is also very clear with vocals and will not be mixed together! The overall dynamic of the music is very good! (December 15, 2020) 2.5 Balanced Conversion Cable: The human voice of this wire is very beautiful, and the high frequency performance is also very clear. Overall, it performs very balanced in my system. I really like this wire!
