IKKO's OH7 in-ear earphones are a real gem in terms of their design and finesse, as well as the integrated components and the incredible sound quality they deliver. Each earphone conceals under its hand-carved Copper shell an all-new 10mm Nano-Carbon dynamic driver. A particularly complex design, resulting in an ultra-thin membrane capable of moving easily. As a result, the OH7 delivers rich, detailed, natural sound, while providing a vast sound stage for total immersion in the heart of your music. The new 90Ω 10mm deposited nano-carbon dynamic driver, the ultra-difficult deposition process makes nano-carbon better than the traditional coating process, so that the diaphragm is ultra-thin and maintains sufficient steel. Even at 90Ω in the case of impedance, it is still easy to push. Hand-carved pattern Each pair of headphones is unique, with a unique number on the cable, the shell was carefully carved by hand sculptors, as delicate as jewellery. And the interior of the acoustic cavity has also been polished to make it smooth to prevent the sound from changing due to imperfections in the acoustic cavity.
