When EQ is applied, the bass reportedly responds very well, becoming "boomy yet controlled," indicating that the underlying potential for strong bass is present but might require some adjustment to fully realize . Some users describe the bass as "solid with no boom," suggesting a well-defined low-end that avoids excessive resonance . On certain tracks, particularly those with significant low-frequency content, the bass has even been described as "seismic," highlighting its impactful nature . Conversely, a potential drawback mentioned is that the bass might occasionally "bottom out" on certain demanding tracks .
The midrange performance of the MDR-Z7M2 is an area where some criticisms have been raised. While the mids are often described as "resolving," a recurring observation is an "upper-mid recession" that can result in vocals and electric guitars lacking some weight and body . This can lead to a perception of the midrange sounding somewhat "distant" or "hollow," particularly affecting male vocals . In contrast, one review noted the mids as being "sweet and open," surprisingly rivaling the spaciousness found in some open-backed headphones . A potential contributor to the perceived character of the midrange is a noted 3kHz peak, which some believe can impart a "honky" quality to the sound .
The treble frequencies on the MDR-Z7M2 are generally described as "clear" and well-integrated with the bass emphasis, contributing to the slightly U-shaped tonal balance . The treble is often characterized as "airy" and free from sibilance, offering a pleasant high-frequency presentation . However, when compared to Sony's flagship MDR-Z1R, the Z7M2 is noted to have less treble detail and energy, feeling somewhat "rolled off" in the higher frequencies for some listeners . One review highlighted the treble as being "nuanced with good cymbal and trumpet timbral textures," suggesting a capability for detailed reproduction in this range . A potential issue identified is a dip around 10kHz, which could contribute to the treble sounding too smooth for individuals who prefer a more pronounced high-frequency presence .
A standout feature of the SONY MDR-Z7M2's sound quality is its soundstage, which is frequently described as "surprisingly large and expansive for a closed-back headphone" . This spaciousness contributes to a sense of good spatial depth and width between individual sonic elements . While the soundstage is considered wide and generally better than many other closed-back headphones, it is not as expansive as that of open-back models or the Sony MDR-Z1R . The headphone also excels in instrument separation, allowing listeners to easily distinguish individual instruments within a complex mix . However, the expansive presentation facilitated by the large 70mm drivers can sometimes lead to the imaging sounding somewhat diffuse .
