The ZEALOT S8 is a portable Bluetooth speaker designed for those who want to take their music with them. It delivers 10W of output power through a three-way audio crossover system, which helps balance the sound across its 80Hz to 20KHz frequency range. You can connect your devices wirelessly via Bluetooth 4.0 within a range of about 10 meters, or use an AUX cable for a wired connection. Housed in a durable metal cabinet, this speaker measures 170mm by 72mm and weighs 423g, making it easy to slip into a bag for travel. The internal 4000mAh battery provides up to 20 hours of playback or talk time on a single charge, so you won't have to worry about frequent recharging during long trips. It also includes a built-in microphone and phone function support, allowing you to handle calls hands-free. For those who prefer local files, the device supports memory cards for playing MP3s and other audio formats.
