Although they may seem like an unknown Chinese brand, the company is from Poland. Quality construction and they are In Ear. They can be connected with a memory card, or with a cable (included and made of fabric fibers), or with Bluetooth, or to play from the built-in radio. Of course, I still haven't figured out how to change stations on the radio, but personally, the radio function is useless to me for the purpose I bought them for. Don't expect to hear perfect sound in music, not even in bass, they are more ideal for TV headphones or anything else that doesn't require high-quality music. A charging cable is also included (not the charger).
