Many people surely love hybrid headphones because they are emotional and melodic. Simgot took this a step further with the SuperMix 4. These wired in-ear headphones combine four different types of drivers: a 10 mm dynamic driver for bass, a balanced armature driver for midrange, a planar driver for treble, and a piezoelectric driver for the highest frequencies. This is a new era in the under $150 price segment.

Sound of Simgot SuperMix 4 in-ear headphones

Simgot SuperMix 4

  • Overall presentation: The headphones strive for a balance between musicality and technical performance, but they don’t achieve the desired result. The sound of these in-ear headphones is V-shaped, with a strong emphasis on sub-bass and bright treble, while the mids feel recessed and lack expressiveness. Personally, I found the balance lacking.
  • Low frequencies: The bass focuses on sub-bass but lacks punch and texture. The mid-bass is quite subdued and barely noticeable, making the sound simplified and lacking warmth. Despite good low-frequency extension, the bass is unimpressive and feels too neutral.
  • Mid frequencies: At times, the mids sound quiet and distant, especially on tracks with breathy vocals, where sibilance can occur. The mids are also non-linear, with male and lower female vocals sounding muffled, while the upper register of female vocals is too bright. The same goes for brass instruments: trumpets sound bright, while flutes are muted. Although detail is good, the vocals sometimes get lost in the mix.
  • High frequencies: The treble is energetic, but quickly becomes fatiguing. Cymbals and hi-hats sound too bright, and frequent “s” sounds can be harsh at high volumes. This could be an issue for listeners sensitive to high frequencies.
  • Detail retrieval: The detail in the Simgot SuperMix 4 is good, with no complaints.
  • Soundstage: The soundstage of the Simgot SuperMix 4 is wide, but there is sometimes a lack of focus, leading to blurred sound. Frequency separation is acceptable, but doesn’t always allow for precise localization of instruments.
  • Conclusion: The SuperMix 4 from Simgot is frankly disappointing. While the sound has some strong points, it suffers from a lack of body in the mids, harsh treble, and weak bass. The detail is on par with competitors, but the soundstage, while wide, is often blurred and unclear. These headphones do not meet their ambitions and are unlikely to satisfy discerning listeners.
  • Genres: Simgot SuperMix 4 might be suitable for genres where bright treble and a wide soundstage are important, such as electronic music and pop. However, due to the lack of body in the mids and weak bass, they are unlikely to be suitable for rock, hip-hop, or genres that require a warmer and richer sound.

Conclusion

  • Sound under $500 – 5.5/10.
  • Sound under $150 among hybrids – 7/10.

Comparison with Competitors

  • Among the headphones I’ve listened to, the only ones comparable in price and design to the Simgot SuperMix 4 are the Truthear Nova. Although the Nova doesn’t have a piezoelectric driver and shares similar issues with the mids, these problems are not as pronounced as in the SuperMix 4. The low and high frequencies of the Nova sound more natural and realistic compared to the Simgot, making the SuperMix 4 the clear underdog among its competitors.

Design, Package, and Comfort of Simgot SuperMix 4

The headphones come in a beautiful green box with an X-ray image of the headphones on the front. The back of the box contains technical information and an exact frequency response graph.
The unboxing of the SuperMix 4 did not leave much of an impression. Inside the box, there were few accessories, giving the feeling that something was missing from the package.

  • Headphones: The resin body with a metal faceplate is slightly larger and features a resin sound tube instead of a metal one. The sound tube lacks a rim to prevent the eartips from slipping off. The design with a black body and gray faceplate looks elegant, and the large copper ring on the faceplate is interrupted by a compensation hole with a fine silver mesh inside. This allegory resembles the trajectory of a planet and adds aesthetics to the headphones. The fit is comfortable thanks to the ergonomic shape and light weight. Passive noise isolation is decent.
  • Cable: The cable deserves the highest praise. It is noticeably improved compared to previous Simgot models. Two tightly braided silver strands end in black connector sleeves. The cable is better constructed and overall justifies the price.
  • Eartips: The package includes three standard silicone tips, which is somewhat modest for this price range. The package is clearly lacking.
  • Case: The case is standard and unbranded, but well-made and adds a touch of elegance with a gold zipper.
  • Quality of materials – 8/10
  • Design – 7.5/10
  • Comfort – 8/10

Final Verdict

Simgot has made a significant step forward in the hybrid sector by creating the SuperMix 4 in-ear headphones with four different types of drivers: dynamic, balanced armature, planar, and piezoelectric. While this first attempt is not without its flaws, I hope the company will continue to develop this concept and offer improved models in the SuperMix 4 lineup with enhanced performance and sound quality.

Simgot SuperMix 4 leaves mixed impressions. They offer a wide sound range and good detail, but their tuning, with an emphasis on sub-bass and bright treble, may not appeal to everyone. The mids seem thin and lack expressiveness, and the lows are unimpressive in texture and punch. The soundstage is wide but sometimes blurred, which worsens focus. Overall, the SuperMix 4 might appeal to fans of bright and detailed sound, but they are unlikely to satisfy discerning audiophiles looking for a more balanced and rich sound. The headphones don’t fully live up to high expectations, but they are a promising model with potential for further development.
