The Cellularline Music Sound are on-ear headphones designed for versatile listening, offering both wireless connectivity via Bluetooth 5.3, which maintains a stable connection within a range of 10 meters, and a wired option. They deliver audio across a frequency range of 20 Hz to 20,000 Hz with a sensitivity of 118 dB SPL/mW and an impedance of 20 Ohm, ensuring clear sound reproduction for your daily playlists. A built-in microphone allows you to handle calls easily using the integrated buttons for answering, ending conversations, and managing volume or playback. Constructed from ABS plastic, these headphones weigh 160 g and measure 178 x 77 x 235 mm, making them light enough for extended wear. The 300 mAh battery provides up to 16 hours of playback on a single charge, which takes about 2.5 hours via the USB Type-C port. For those moments when you prefer the wired connection or need to connect to older devices, they include an RCA output jack and a 1.2 m cable.
