Rolling Force Cosmos Review: Into the Mystique Euphoria

Cosmos Paired with AME Raven (Review coming soon)

Raven is famous for excellent bass performance despite using a full BA+EST setup for the drivers, yet there are always better possibilities – especially if we’re introducing Cosmos to them. Once paired, Cosmos simply brings me to the next chapter of Raven. It’s surprisingly considering the O&W cable is already a flagship-tier cable. Cosmos brings out significantly deeper-diving bass with darker, deeper nuance, all while keeping the clean bass resolution which is one of Raven’s specialties.

 

The overall improvement of the bass portion is significant, bringing a satisfying upgrade for the ultra-low extension. The cleaner bass reverbs, ringing, and vibrations just do a big favor for Raven to gain even better depth.  Cosmos refuses to do the same as other cables that simply boost the bass as the bass quantity barely increases, all while bringing these improvements. Fuller body without giving up agility. If we say the strength of Raven’s bass presence was 3/10 (just to relatively compare), Cosmos brings up to something like 7/10. Not the quantity! But the quality and depth.

 

The lengthy deeper, fuller, nuance I’ve been mentioning for the bass also applies to Raven. Though Rolling Force sure did care about precise tuning. If the effects I’ve mentioned for the bass portion were to be applied to the mid-range as well, the vocals would obviously get recessed or lose transparency. Mids and highs don’t deliberately boost the intensity but gain stronger dynamics and energy. The density is also more packed with glittery-lush texture. Mids show a natural boost in resolution and slightly get closer in position. The atmospheric improvement is why Rolling Force gave this cable its name “Cosmos”, as the staging becomes vast and grand, significantly upsizing the headroom.       

 

Cosmos Paired with Noble Sultan

The first difference I feel is the wider, grandeur staging. The playground for the bass to play gets a major upgrade in size and scale, not only giving wider room for the bass but also giving depth. This also means better unveiling the ultra-low extensions. Don’t worry about making your bass to be overdone or blurred up in resolution. Cosmos doesn’t simply stop from boosting the bass performance but also serves as your IEM’s “house cleaner” for the low range, all while offering the benefits I’ve mentioned before. Sultan’s bass gets tighter in reverbs and reverbs the glimpse of muddiness that were present with the stock cable. Cosmos also gives a seamless yet distinctive separation between the sub-bass and lower vocals, further preventing the sub-bass from bleeding into the mid-range.   

 

Another thing I’d like to highlight is that the background ambiance that was hidden is now heard once switching from the stock Noble cable to Cosmos. Those small breaths, micro reverbs, the soft decay…. these kinds of ambiance. This may seem like a minor difference, yet looking at the wider picture (or should I say listening to music overall), this gives a significant sense of liveliness. It just gives life to the music. Alongside, while the natural sub-bass distinction that Cosmos brings benefits the vocals’ clarity, Cosmos still mildly pulls the vocals and highs closer to the ears, accompanied by a creamier tone and gold-glittering lushness of texture. It doesn’t alter the original timbre, yet the maturity of nuance can be heard instantly. The crispiness and transparency of the upper frequencies also get mildly stronger, yet not majorly.  

    

The last improvement is more towards the overall musicality of Sultan. Cosmos seamlessly improves Sultan by making the sound more universal – while the stock cable did a fine job creating a harmonic sound through different types of drivers, Cosmos noticeably does a better job at this. While retaining all the benefits of using different drivers for different purposes (as intended for Sultan), the tone and texture become more consistent throughout the spectrum.
