If you want comfortable, over-ear headphones for immersive listening and reduced outside sound, choose AUDIX A152; if you need compact, wired in-ear monitors with a four-driver design and detailed sound, choose HIFIXAUDIO SIMGOT SuperMix 4. For small ears, the key difference is the fit style: the A152 surrounds the ears, while the SuperMix 4 sits in the ears, though the available specifications do not establish which will fit a particular person better.
AUDIX A152 vs HIFIXAUDIO SIMGOT SuperMix 4 at a Glance
• AUDIX A152 strength: Over-ear, closed-back design with padded earcups, a padded headband, and 90-degree swiveling cups. Trade-off: It is a wired, over-ear headphone, not a small in-ear option.
• HIFIXAUDIO SIMGOT SuperMix 4 strength: Four driver types—a dynamic driver, balanced armature, planar driver, and PZT transducer—are combined in a wired in-ear monitor. Trade-off: Its in-ear shape may not suit listeners who prefer an over-ear fit.
• For listening and monitoring: The A152 includes two detachable cable lengths, a carry case, and a threaded adapter for a quarter-inch connection.
• For compact wired listening: The SuperMix 4 has a 3.5 mm connection and a 0.78 mm 2-pin cable connector.
• Who each suits: Choose the A152 for an over-ear listening setup; consider the SuperMix 4 if you prefer an in-ear monitor and want its hybrid driver arrangement.
The A152 is a dynamic, closed-back, circumaural headphone designed to cover the ears. Its 50 mm drivers are specified for a frequency range of 8 Hz to 28 kHz, and Audix describes its sound as balanced, spacious, and extended in the bass. That combination points toward listeners who want a full over-ear presentation for music, gaming, or critical listening rather than a tiny earbud-style fit.

The practical extras are useful if the headphones will move between rooms or workspaces: the cable detaches, two cable lengths are included, and a protective carry case comes with the set. I would skip the A152 if you specifically want an in-ear design, a wireless connection, or a compact set of earbuds for a pocket. It is an over-ear model, and its stated use is for adults.
The SuperMix 4 takes a more elaborate in-ear approach. Its hybrid system combines a 10 mm dynamic driver, a balanced armature driver, a micro planar driver, and a PZT transducer. The product information gives a frequency range of 8 Hz to 40 kHz and describes separate acoustic paths with a tuned four-way crossover. For someone comparing wired in-ear monitors, those specifications make it the more specialized choice of the two.
Its stated sound goals include textured bass, natural-sounding mids, smooth highs, and detailed treble. The design is presented for music listening, gaming, and professional monitoring. The in-ear placement may appeal to listeners who would rather not wear earcups around their ears, but the provided information does not give dimensions or confirm a small-ear fit. A small-ear shopper should not assume the shell will fit comfortably based on the product name or driver count alone.
The SuperMix 4 uses a 3.5 mm jack and a 0.78 mm 2-pin cable connector. Its shell combines 3D-printed resin with a CNC-machined metal faceplate, and the cable is described as silver-plated with a flexible jacket. It is still wired, so it is not a wireless kids headset for small ears, nor is it a solution for someone who needs fast charging. The available information also does not specify a microphone, so I would not choose it specifically for calls without confirming that requirement separately.
• Prefer headphones that sit around your ears → AUDIX A152. Its circumaural design, padded cups, and padded headband make the fit style clear.
• Prefer an in-ear monitor → HIFIXAUDIO SIMGOT SuperMix 4. It is explicitly an in-ear model, though fit for small ears is not established by the listed details.
• Want a 50 mm dynamic-driver headphone → AUDIX A152. The A152 uses a single dynamic-driver type and lists an 8 Hz–28 kHz frequency range.
• Want multiple driver types in one wired earphone → SuperMix 4. Its hybrid design combines dynamic, balanced armature, planar, and PZT drivers, with a listed range of 8 Hz–40 kHz.
• Need cable flexibility for a stationary setup → AUDIX A152. It includes detachable 3 m and 1.8 m cables, plus a 3.5 mm-to-quarter-inch threaded adapter.
• Want a compact cable connection format → SuperMix 4. It has a 3.5 mm jack and a 0.78 mm 2-pin connector.
• Want one-ear monitoring → AUDIX A152. Its earcups swivel 90 degrees, a specific feature relevant to monitoring with one ear.
• Looking for the best fast charging sports earbuds for small ears → Neither is a clear match. Both products are wired, and neither sheet describes charging or sports-specific features.
I would choose the AUDIX A152 if I wanted a comfortable over-ear headphone for longer listening, with detachable cable options and a carry case. Its fit and practical accessories are more clearly described, and the swiveling cups add a useful monitoring option.
For small ears, I would not declare either a guaranteed fit: the A152 goes over the ears, while the SuperMix 4 is an in-ear monitor with no stated shell dimensions. My recommendation is the A152 for a general over-ear setup; I would choose the SuperMix 4 instead only if I specifically wanted its wired, four-driver in-ear design.
The A152 is an over-ear headphone, while the SuperMix 4 is an in-ear monitor. Neither product information set provides fit measurements for small ears, so I would choose based on whether you prefer earcups or an in-ear fit rather than assuming either will fit perfectly.
No. Both are wired products. The A152 connects through a 3.5 mm jack and includes detachable cables; the SuperMix 4 uses a 3.5 mm jack with a 0.78 mm 2-pin cable connector.
The product details do not specify a microphone for either model. The A152 is described as reducing sound bleed into microphones, but that does not mean it includes one. I would not treat either as a confirmed call headset based on the listed information.
Not automatically. The SuperMix 4 offers four driver types in an in-ear design, while the A152 uses 50 mm dynamic drivers in a closed-back over-ear design. Those are different listening formats and feature sets; the right choice depends on whether you want an in-ear monitor or over-ear headphones.
