 Sophisticated processing 4-Way Crossover technology
DM7 adopts the industry standard 4-Way crossover technology, the drivers transmits sound waves through 4 separate channels equipped with 3 Knowles filters and 1 patented acoustic damper, which divide the extremely high, high, medium and low frequencies. It makes the overall curve smooth and coherent and the sound real and vivid, removing any fatigue even when listening for a long time.

High quality MMCX interface
DM7 use the MMCX standard to connect the cable, as it can effectively solve the problem of earphones becoming useless because the cable breaks, and it also allows to change the tuning through the cable and provides more options to upgrade the cable.
 Pluggable MMXC interface
 
 Audiophile Cable
 Stock cable is an 8-core mixed single crystal copper + single crystal copper silver foil wire: not only does it allow for lossless signal transmission with improvements to sound quality, it also is good enough to no longer make you worry about upgrading.
 Customized wearable experience
The ergonomic design allows the earpiece to fit the ear canal, avoiding discomfort even after a long time, also dispersing ear pressure, so as to let you enjoy the fun of music. We partnered with Siemens to access their ear canal database: we analysed and compared data on tens of millions of ear canals to obtain earpieces that fit the human ear perfectly.
 
Hi-res high quality audio certification
DM7 has been certified by Japanese Audio Association as "Hi-Res Audio", bringing you a listening experience beyond CD level.
