BQEYZWinter Ultra (3.5mm4.4mm) Dynamic + Coil Bone Conduction Hybrid Wired Earphones Canal Type Blue

[Driver structure] ① Bone conduction unit Mainly compensates for loss in mid- and high-frequency ranges and transmits vibrations from the bone conduction bracket to the earphone cavity. ②Dynamic driver Responsible for air conduction, mainly controls the mid-low range, and expands the sound field with a dual cavity structure. [Dynamic + bone conduction hybrid type] Hybrid earphones consisting of a 12mm dynamic driver and 11.6mm PZT bone conduction driver. The bone conduction unit controls the frequency by adjusting the rigidity of the bracket and adjusts the brightness over a wide area. [Filter Adjustment] Based on Winter, the filter is adjusted to highlight the vocal rhythm while achieving rich low frequencies. [Switchable 3.5mm/4.4mm plug] 3.5mm/4.4mm plug is included and can be replaced at any time. You can enjoy the plug of your choice according to the equipment you are using. [High-frequency bone conduction technology] The high frequency (high range) of general earphones is transmitted to the eardrum through air vibrations, making it sharp and prone to burrs. Winter Ultra's high frequencies are transmitted through bone conduction, so they deliver clear, unburr-free high frequencies, and reproduce beautiful mid-high frequencies with a full volume that is difficult to express with typical dynamic or hybrid earphones.
