ROSE TECHNICS QuietSea Single Dynamic Earphones with 10mm Topological Black In-Ear Diaphragm, Wired,

We offer a wide variety of products, and the following precautions apply to some of them. Please note that they are listed for all products. 【Voltage Compatibility】Designed for Japanese voltage (90-110V). Using with a different voltage may cause malfunction. 【Plug Type】Japanese plugs (A or B type). Use a conversion adapter if needed. 【Transformers & Adapters】Transformers adjust voltage; adapters only change plug shape. Using an adapter without a transformer may damage the product. 【Liability】We are not responsible for damages caused by improper use, such as using the product without a transformer. The proprietary φ10mm topological diaphragm expands the frequency response range, delivering deeper bass and more melodic treble. Vapor deposition of nanomaterials significantly reduces split vibrations compared to conventional diaphragms, reducing total harmonic distortion to an extremely low 0.1% or less, resulting in exceptional audio performance with crystal clear detail. QuietSea is an in-ear type earphone equipped with a proprietary φ10mm topological diaphragm.
