The UiiSii CX Heavy Bass Earphone uses a Type-C interface, plug-and-play, and lossless transmission to restore actual sound quality and to suit the demands of listening to music, movies, and gaming. Using a 12mm large dynamic coil unit, the bass is more powerful, the performance is shocking like a scene, and listening to music is more fun. The easy semi-in-ear wearing technique significantly lessens the strain on the ear canal while maintaining long-term comfort. The UiiSii CX earphone is lightweight, exquisitely curved, comfortable to wear, and stable when in use. You may change music with the intelligent controller that it offers. With MP3, MP4, tablets, phones, and other devices, you may adjust the volume and take or finish conversations. UiiSii CX headphones have extremely user-friendly TPE cable that is not skin-allergic and superior sound quality.
