Sennheiser HD 206 Headphones Closed-Back

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 closed-back design provides noise isolation, preventing sound leakage from being absorbed by nearby recording devices. Lightweight and comfortable, these headphones are designed for extended listening sessions, studio work, and DJ sessions. The 24-ohm impedance is compatible with mobile phones, tablet computers, portable music players, and studio recorders. Includes 1/8-inch (3.5mm) and 1/4-inch (6.3mm) plug adapters.
