Compact design, ideal for on-the-go use. 30mm driver unit for powerful sound. Frequency range from 10 to 24,000 Hz. Microphone and remote control. Headphones can be folded together at the ear cups. Connection options: wired. Detail color: white. Closed design. The completely closed design of these headphones is not very breathable, but it provides powerful sound and rich bass. Additionally, disruptive external noises are well dampened. Conversely, good insulation is also ensured: outsiders can hardly hear your music. On-ear headphones for high wearing comfort. On-ear headphones rest directly on the ear cup. Due to their design, they offer high wearing comfort, even if you want to listen to music for an extended period. They provide a free, spatial sound and only partially shield external noises. Therefore, they are ideal for quieter environments or if you want to be aware of some ambient sounds, such as the ringing of a phone or doorbell.
