BQEYZ[]Winter Ultra (3.5mm/4.4mm) Dynamic + coil bone conduction hybrid wired earphones Canal type blue

【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.

[Driver structure] ① Bone conduction unit Mainly compensates for loss in the mid-to-high range 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 rhythm of the vocals while achieving rich low frequencies. [Switchable 3.5mm/4.4mm plug] Comes with a 3.5mm/4.4mm plug that 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.
