The Musen AKZ-606 are wireless on-ear headphones designed for those who value long-term reliability and comfort. They utilize Bluetooth v5.4 to maintain a stable connection within a 10-meter range, while the 40 mm drivers deliver a frequency response from 20 Hz to 20 kHz. An integrated microphone allows you to handle calls without needing to reach for your phone. These headphones are built for endurance, offering up to 40 hours of active battery life and an impressive standby time of up to 180 days. When the power runs low, a full charge takes approximately 2 hours via the included charging port. The black finish is complemented by a foldable construction and an adjustable headband, which, along with the soft ear pads, makes them easy to pack and comfortable for extended listening sessions.
