Mera&x27;s sound is not partial, both quality and sense of hearing. The low frequency of Mera does not emphasize the quality as much as the traditional metal earplugs, but the sound is smooth and smooth. At the same time, the low frequency sense of Mera is moderate, the diving depth is in place, and the overall texture is full and strong. The listening feeling is not dull, but it is fist to flesh. Mera&x27;s most pleasant and pleasing part is its outstanding dynamic performance. Its voice is not thick and its drum beat is not disordered. Moreover, its slow dynamic response also makes the overall listening feeling more stable. The overtone and residual sound of Mera are rich and elastic after diving at low frequency. What I am satisfied with is that the sound is real and natural, and the rich atmosphere adds some flavor to the listening feeling.
intermediate frequency
Compared with the sound performance of most metal earplugs, the sound of Mera has a lot of temperature. The sound density of the medium frequency part of Mera is relatively loose, the thickness is relatively moderate, and the overall sound style is mild and moist. Although Mera&x27;s voice is neutral and balanced, her emotional expression is appropriate. Human voice is the most prominent part of Mera. It is not only close to the ear and forward, but also more suitable for sweet female voice in terms of male and female voice. The emotional expression is very delicate. Especially when listening to the songs of old-fashioned pop female singers, the deep and meaningful flavor is intriguing, and Mera can retain the true feelings. At the same time, Mera well separates the voice from the background music to ensure the orderly sound output, and the sense of hearing is not easy to be confused. Generally speaking, Mera pays more attention to the expression of emotional taste in the interpretation of sound, which is more suitable for listening to popular vocal music.
high frequency
Mera&x27;s voice does not belong to the passionate type, but follows a solid listening sense. The high frequency part of Mera doesn&x27;t pursue the ultimate sound performance, but it shows strong enough quality, which is rare for moving coil earplugs. Mera&x27;s high-frequency extension is spacious, and its voice extension ability is outstanding, and the extension is not rigid. The overall treble is exquisite and pleasant, but not abrupt and exciting. The stable and comfortable treble line feeling is very meticulous. The transparent sound sense is the embodiment of Mera&x27;s high frequency quality. At the same time, the style will not be too bright or dim when the brightness is properly controlled. In terms of instrumental music, Mera is more suitable for popular instruments, especially string instruments.
sound field
Mera&x27;s momentum is surging and atmospheric, the whole circle flavor is strong, the sound field is open and the emotion is unrestrained. Compared with the longitudinal sound field, the transverse sound field of Mera is wider and tends to be elliptical shape, and the sound is clear and regular. Combined with excellent dynamics, Mera is very good at controlling small organizations.
Tip diaphragm design
Keep audio undisturbed
Using advanced diaphragm and integrating two main different materials to avoid the interference source of audio distortion in the beginning, this new diaphragm greatly reduces the internal noise resonance. With precisely configured magnets, the Mera becomes an easy to drive dynamic headphone with no distortion of sound and keeping it free and smooth.
Copper alloy damping nozzle
Copper alloy acoustic damping (CAAD), using this kind of nozzle design, the Mera can achieve high frequency performance and high fidelity medium frequency hearing.
Hexagonal anti resonance cavity
Zero phase error
Mera uses patented hexagonal anti resonance cavity architecture (HBSC) to achieve zero phase error and improve transparency. The special internal structure design completely changes and adapts to the performance of various sound sources on headphones.
