Soft Ears RSV Review – Mastering Versatility

Pros –

Flawless gloss finish, Comfortable and well-isolating design, Quality stock cable, Highly refined and versatile tuning, Excellent dynamics for a BA design, Jack of all trades master of many, Easy to drive

Cons –

Treble extension and sub-bass definition could be improved, Soundstage depth just above average in-class

Verdict –

The RSV is one of the most well-rounded and instantly likeable earphones I’ve tested, representing an excellent value proposition even at its elevated price tag.


Introduction –

Soft Ears are the luxury division of the now widely renowned Moondrop, seeking to offer a more refined experience at more premium price tiers. Their product portfolio is more focused and mostly high-end focused. This starts at their all-out co-flagships, the 10x BA driver RS10 reference monitor and their Tribrid Cerberus. Alternatively, the Turii offers a high-end single-DD configuration that has become more popularised in recent years. The RSV is their cheapest model if not a cheap earphone in isolation. The team spent 1 year honing it to perfection, aiming to offer a scaled back version of the RS10 experience with the same technologies and engineering on a simplified and easier to drive 5-BA platform. Compared to the flat out reference RS10, the RSV has been slightly reworked to provide a heavier emphasis on dynamics. Its engaging yet immaculately clean sound, ease of driving and more accessible price point makes it a great choice for audio enthusiasts.

The RSV comes in at $729.99 USD. You can read all about it and treat yourself to a unit here.

I would like to thank the team at Soft Ears very much for their quick communication and for providing me with the RSV, RS10 and Cerberus for the purpose of review. All words are my own and there is no monetary incentive for a positive review. I paid a slightly reduced cost for the earphones in return for honest evaluation and will attempt to be as objective as possible.

Behind the Design –

Tuned Acoustics & Crossovers

The combination of electronic crossover and passive filters has enabled Soft Ears to achieve their desired note presentation in addition to their ideal frequency response. Using a 3rd order LRC filter for bass, impedance + low-pass for the midrange and film capacitors for the high-end, the company was able to achieve both whilst maintaining almost linear phase. This is aided by the 3D-printed shell and internal acoustics, leading to maximised extension, resolution and sharper imaging.

VDSF Tuning

Moondrop pioneered the VDSF tuning curve which is a combination of the diffuse field neutral and Harman Curves which have become industry standards as of late. Every model lies on a spectrum between both. The Moondrop sound has become hugely popular with users and critics alike due to its combination of timbral accuracy, balance and improved listenability over time compared to the vanilla Harman and DF Neutral curves. The RSV represents one of the most refined takes on it yet.

Unboxing –

The RSV has the most exclusive unboxing of the Soft Ears line-up with a large magnetic box that folds open to reveal the leather carrying case and accessories within a separate box. The case contains the earphones and cable. Each earpiece comes protected within a fabric pouch that prevent scratches during shipping. The accessories include 3 pairs of silicone tips in addition to 3 pairs of memory foam tips that offer a warmer, softer sound. In addition, a cleaning tool is provided alongside a metal Soft Ears card. Of note, the tips have an especially large bore size which can limit aftermarket pairings. The stock tips also have a seat promoting a more homogenous fit depth, likely in order to provide a more consistent sound between listeners. As there was such a heavy emphasis on tonality on this earphone, I decided to stick with the stock ear tips, of course, experiment for your preference if this is not to your liking.

Design –

As a huge car fanatic, the RSV invoked some primal instinct in me. From the sleek, smooth yet symmetrical styling to the gold foil inlay atop carbon fibre faceplates, the RSV advertises its sporty, high-performance nature. I am a huge fan of the combination of texture and simple yet flawlessly finished 3D printed piano black that oozes quality even in the absence of metal and its associated density in the hand. With its solid 3D-printed design, the RSV feels far more substantial than your average acrylic monitor. If I had one complaint, perhaps the nozzle could have a small ridge to help tips stay attached as those with wet wax may find themselves having to clean them frequently.   

Up top are 2-pin 0.78mm recessed connectors compatible with a wide range of aftermarket options. The stock cable leaves little to be desired, with a smooth matte jacket and very sturdy yet minimally cumbersome construction. The wires are a little springy though it is supple enough to coil without issue and microphonic noise isn’t exacerbated either. The pre-moulded ear guides are comfortable and the connectors complete the aesthetic with their clean matte black finish. Altogether a well-considered package, perhaps a modular or balanced termination could have been employed. Arguably, their use of the widely adopted 3.5mm standard is in line with the company’s intentions that this monitor should be enjoyed from almost any source.

Fit & Isolation –

This is a medium-sized earphone and its fit will be reminiscent to anyone familiar with faux-custom style monitors. It sits comfortably in the outer ear and its rounded design is devoid of features that may cause hotspot formation over time. It protrudes slightly, meaning they won’t be suitable for sleeping on, but the RSV isn’t especially bulky either. For my ears, they were comfortable for hours on end and I achieved a strong, consistent seal. Due to its fully sealed design and well-shaped body, the RSV is very stable and forms a great seal with its slightly deeper fit. Those sensitive to wearing pressure will have a similar experience here to other sealed in-ears that said. In addition, wind noise isn’t an issue and isolation is strong, great for commute and even travel, especially with foam tips installed. This also means the earphones don’t require huge bass emphasis to sound great in louder listening environments.

Moondrop Blessing 2 Review – All The Boxes

Pros –

Very linear tuning, Outstanding detail retrieval, Excellent imaging and separation, Impressively source agnostic, Great design and cable

Cons –

Larger housings, Slightly strained upper-midrange, Slightly thin lower-treble

Verdict –

Few competitors create as well-rounded a package as the Blessing 2, this is a balanced and refined earphone that punches well above its asking price.


Introduction –

If you frequent any kind of audio for a, you will be well acquainted by now with Chinese cult-hit Moondrop. For the company has achieved huge renown in a very short time, no small feat, with their excellent VDSF tuning based on the coveted diffuse field neutral curve. The Starfield assumed such a tuning, that permit surprising refinement at a reasonable price. However, though tonality impressed, the quality of the driver did leave me wanting. The Blessing 2 looks like a fine solution, assuming a very similar tuning realised through an elaborate 5-driver hybrid setup. The Blessing 2 implements 3D printing for physical band and low-pass filtering used in conjunction with electronic RC filtering to deliver a phase-coherent 3-way setup and very specific control over the frequency response. That’s a load of engineering for a midrange IEM.

The Blessing 2 retails for $319 USD. You can read more about it and purchase one for yourself on HiFiGO and Apos Audio.

The Pitch –

Hybrid Acoustic and Electronic Filters

The Blessing 2 implement physical band-pass filtering that isolates one pair of the BA drivers to exclusively cover the midrange frequencies. The BA drivers are a custom 2 in one unit from Soft Ears Japan tuned to their specifications. Similarly, Moondrop use a physical low-pass filter to limit the DD to bass under 400Hz in addition to controlling pressurization. An electronic RC filter is also utilised to reinforce this. SFWK tweeters provide extended high-frequencies and special attention was given to unite the sensitivities of all drivers acoustically rather than electronically for a phase-coherent design.

VDSF Tuning

Neutral has become a more subjective term over the years as more minds contribute to different curves simulating different acoustic environments. Most famous are the Diffuse and newer Harman curve, both have their share of fans and critics. Moondrop’s first IEMs traced the Harman Curve incredibly well, a selling point for the company and sound foundation for developing their own curve called virtual diffuse sound field (VDSF). Similar to its name, this is Moondrop’s appropriation of the diffuse-field neutral curve, not the Harman Curve. Comparatively, they’ve toned down the highs and upped the bass which is, to my ear, a combination between the two aforementioned curves. Though both diffuse-field and Harman are considered by most critics not to showcase great balance, the VDSF curve is a refined and mostly natural-sounding tuning that is a very effective mashup.

Unboxing –

Moondrop always package their products professionally and the Blessing 2 is no exception. The outer sleeve houses specifications and Moondrop’s famous anime splash art. Inside is a clean grey box adorned with Moondrop’s logo. Opening the box reveals the carrying case and separate card box with additional accessories. The earphones are protected within a foam inlet inside the zippered case, it has a nice textured vinyl exterior in svelte grey and ample interior space for the earphones and a small DAP too.

The box contains the rest of the accessories, a 6n OFC Litz cable, airline adapter, papers and 6 pairs of silicone ear tips. The tips have an interesting design, the bore fits exactly onto the Blessing 2’s nozzles but the size of the sound output has been reduced likely to slightly attenuate high frequencies and create a more balanced sound.

Design –

The Blessing 2 is a very attractive earphone to my eye, an impression enhanced by a certain amount of customisability on the user’s end. The 3D printed shells are as you’d expect; perfectly smooth, seamless and unibody, they’re also resin-filled for a nice quality heft in the hand. Meanwhile, the transparent design showcases the acoustics inside and driver setup, you can study them for hours. This is topped with CNC machined faceplates with a brushed finish. Buyers are able to order wooden variants and custom artwork for an additional $30, or choose from 8 set options provided by Moondrop.

The cable too inspires confidence, I’ve personally had a great experience here. Up top, they utilise a standard 0.78mm 2-pin connector with wide aftermarket support. It’s a 4-core braided unit with soft, smooth jacket and very supple feel, the cable is slightly thin but feels well anchored at all terminations. There’s also zero memory so the cable isn’t too tangle-prone, and it conducts minimal microphonic noise. The well-relieved right angle plug and metal Moondrop y-split cover add a premium feel while the pre-moulded ear guides provide a comfortable and stable fit. I personally enjoy the contrast created between the copper cable and silver housings.

Fit & Isolation –

If there’s one thing that may polarise about the Blessing 2’s design, it’s likely the fit. They are ergonomic in their design for sure, but definitely also on the larger side. They aren’t ridiculously proportioned nor do any design decisions come at the cost of ergonomics. This is a rounded, smooth and generally comfortable design with well-angled nozzles that promote a deeper, more stable fit and strong seal. I didn’t experience any hotspot formation, albeit due to the size, they don’t disappear in the ear. Those with smaller than average ears may experience difficulties due to the height of the earphone as the tops lock-in somewhat to the anti-helix area.

With the right tips, they achieve a deep and comfortable fit. In turn, though reasonably large and quite wide, the fit is lower-profile, hugging the contours of the ear. You can’t sleep on them due to the width but wind noise is not too bad despite the presence of a faceplate vent. Similarly, isolation is well above average and easily suitable for commute and public transport. You would benefit from a fully-sealed design in especially noisy areas such as the metro or air travel, but the Blessing 2 is passable here too, especially with foam tips.
