The Musen Max 500 are black on-ear wireless headphones designed for versatile use with smartphones, tablets, and laptops. They utilize Bluetooth v5.4 to maintain a stable connection, while the integrated microphone allows you to handle calls and voice commands without reaching for your device. A digital LED display on the chassis keeps you informed about the current mode and remaining battery life at a glance. These headphones offer a frequency range of 20 Hz to 20 kHz and provide over 15 hours of continuous music playback or talk time on a single charge. If you prefer not to rely on a paired device, the built-in TF card slot lets you play audio files directly. A full recharge takes approximately 2 hours, supporting a standby period of over 200 hours for those who use them intermittently throughout the day.
