Sound

Low

The Softears Studio 4 establishes its sonic foundation with nicely balanced low-frequency performance. The sub-bass frequencies are thoughtfully tuned to align with the Harman Target, with ever so slightly more control. This meticulous tuning imparts a dynamic energy to the lows, endowing them with a captivating sub-bass resonance that resonates with controlled authority while still being in control and not offending, definitely not a basshead IEM, would not satisfy the bassheads out there for sure. 

Despite the absence of a dynamic driver, Softears has ingeniously managed to craft a bass response that mirrors the characteristics of a true dynamic driver. The bass is punchy, remarkably controlled, and extends impressively into the sub-bass realm.

Mid

The midrange performance of the Softears Studio 4 is a testament to tonal accuracy and timbral authenticity. Its lower-midrange is neutral and precise, ensuring that vocals and instruments are rendered with striking clarity and definition. Stepping into the upper-midrange, the Studio 4 takes a step forward. 

This infusion of forwardness enhances vocals and instrumental solos, breathing life into performances with remarkable fidelity and emotional resonance. Overall, the midrange is strikingly well-balanced, with an exceptional presentation of vocals, and the pinna gain is thoughtfully calibrated to prevent any hint of shoutiness. In the realm of tuning, the Studio 4 stands out as one of the finest examples in its category.

Highs

The treble out of these is outstanding, it extends well without being too sibilance, and the technical performance is also up to the price bracket and throws impressive details at the listener, Although not overly detailed it is still spacious and barely ever feels congested, The tonal balance of the lows mids and highs are perfectly done here. 

The treble incisiveness is good as well, and provides a clean and fast image, although I would not consider it to be as smooth as higher-end offerings from Softears, the overall performance in the treble is noteworthy for this price point.

Lows:
The Studio 4’s bass is punchy, controlled, and extends well into the sub-bass region. It prioritises accuracy and balance in the low frequencies. Contrarily, the RSV excels in bass performance with a robust and impactful low end. It offers an engaging sub-bass rumble that resonates with authority, providing depth and power to the overall sound. The low end on RSV feels a bit more juicy and has more mid-bass authority and that oomph and authority.

Midrange:
Studio 4’s midrange is neutral and precise. It delivers vocals and instruments with clarity and definition, aiming for tonal accuracy. The RSV boasts a forward and captivating midrange. Its lower midrange is neutral, while the upper midrange embraces pinna gain ever so slightly greater than what Studio 4 aims for, adding a sense of forwardness to vocals and instrumental solos. This results in emotional resonance and remarkable fidelity. Mids on both of these IEMs are pretty accurate and well-balanced; one cannot go wrong in this department with either of these.

Treble:
The Studio 4’s treble is balanced, with a focus on accuracy. It offers natural transient attacks without venturing into sharpness. A mid-treble dip adds warmth to the sound, and the upper-treble maintains neutrality. RSV’s treble balances warmth and precision. It features a natural lower-treble and a mid-treble dip that is more than Softears Studio 4, which adds a warm, analog-like character to the sound. The upper-treble maintains neutrality and contributes to a balanced presentation. Although the quality of treble from RSV feels more tonally satisfying, the details and resolution however are on par on both the IEMS.

Soundstage:
The Softears Studio 4 is likely designed to provide a precise and focused soundstage, which is common in studio-oriented IEMs. The RSV is noted for its wider and deeper soundstage, which contributes to a more immersive listening experience, especially for audiophiles who value spaciousness.

af

Lows:
The Aful Performer 8 features a controlled bass response with good impact and rumble in the sub-bass region. However, it leans towards a leaner and drier sound profile compared to most hybrid IEMs. The dynamic driver in the P8 allows it to have a good punch and rumble. While it doesn’t have a pronounced mid-bass, the bass quality is praised for its tight texture and overall quality. 

Compared to the Softears Studio 4 the bass on Aful Performer 8 has more sub-bass than midbass, overall quality and quantity are similar, but the authority is more felt on P8 probably due to the usage of DD. Although Studio4 has some of the best BA bass and does not lag behind too much. Both of these IEM’s would easily satisfy anyone with their bass, just maybe not bassheads, but other than that the bass on both of these are as enjoyable as it can get.

Midrange:
The P8 boasts high resolution and clarity in the midrange. Vocals and instruments are well-defined and clean. However, the mid-range can sound somewhat dry due to a lack of fullness. This results in a spacious and airy presentation. While some may prefer a fuller mid-range on the Softears Studio 4 , the P8 impresses with its detail, dynamism, and transparency. P8 does not put the vocalist in the front like Softears Studio 4, however, it positions everything in a more balanced form. Nothing is outstanding on its own, however, it has a very soothing vocal experience, The vocalists are well separated here without being shouty, and the mids have good texture. P8 tonality goes well with most genres of music, throw anything at it and it handles beautifully. 

Not that S4 cannot do the same, but in some genres especially some that are vocal forward by default could make the sound not so enjoyable compared to P8, while comparatively in some genres Softears Studio 4 would sound much more vivid than P8 due to its vocal forwardness. The mids being the most different factors for both IEM, both of them excel at mids just take a different approach to their presentation, S4 following a more common Harman-oriented pinna gain signature, whilst P8 lining more closely with 64Audio U12T and Dunu SA6 signature (Check our review and comparison of the Aful Performer 8 with Dunu SA6 MK2). Overall both of these IEMs would handle every genre thrown at them, the ones looking for vocal forwardness would prefer the Softears Studio 4 more while someone would want everything to sound smooth and just lust and enjoyable, separated yet not forward would prefer the P8 here.

Treble:
The Aful Performer 8’s treble is crisp, dynamic, and detailed. It showcases excellent detail retrieval, allowing you to hear intricate nuances in music. While the treble is energetic and well-extended, it lacks the incisiveness and airiness that is produced by the Softears Studio 4. Aful Performer 8 sounds more comfortable for listening for a longer period of time, it never gets fatiguing, shouty, or sibilant, and it’s overall a more forgiving tonality. Softears Studio 4 in comparison has more airiness, and treble extension is on par however the details are more in the face with Softears Studio 4.

It’s not like Aful Performer 8 is not detailed but the details are not into the face, and opt for a smoother texture. Aful Performer 8 can be rounded off as an IEM that is a jack of all and master of none. It plays everything so beautifully that there is little to fault, yet it does not specialize in any specific region. In a gist, the Softears Studio 4 is more airy and incisive and Aful Performer 8 is more smooth and natural sounding.

Soundstage:
The soundstage on the P8 is not that wide, although the IEM could be a great gaming thing due to its ability to pinpoint the sounds exactly, the soundstage on S4 feels a tad bit wider, although not much of a difference here both IEMs have an average soundstage.
