The Cellularline Music Sound Fantasy are true wireless in-ear headphones designed for those who appreciate a touch of style in their audio gear. These earbuds utilize Bluetooth 5.1 to maintain a stable connection with your iPhone, Samsung, Huawei, or Xiaomi device, while the integrated microphone allows you to handle calls without reaching for your phone. On a single charge, you get 5 hours of playback, which extends to a total of 20 hours when using the included charging case. The case not only stores the earbuds but also adds a visual element to your accessories with its striking black and red grid decorative pattern. Recharging the system via the USB-C port takes between 1.5 and 2 hours, and the device can remain on standby for up to 30 hours.
