ZEALOT B570 Wireless Bluetooth Headphones with 40mm Drivers and 8-Hour Battery for Mobile and Sport Use

The ZEALOT B570 is a wireless Bluetooth headset designed to deliver audio for mobile phones, hi-fi listening, and sport activities. It combines wireless convenience with practical features like a built-in microphone, FM radio, and a long-lasting rechargeable battery. Available in multiple colours, this headband-style headset uses hybrid vocalism technology and 40mm drive units to reproduce sound across a wide frequency range. Its wireless operation allows for movement up to 10 metres from your audio source, while the included 3.5mm connector provides a wired listening option when needed.

Features and Construction

The B570 headset is built around core audio and connectivity components that define its operation. Its construction focuses on delivering wireless audio with control and battery life suited to daily use and active scenarios.

Material and Build

The headset incorporates a 400mAh rechargeable lithium battery, which powers both the Bluetooth connectivity and the speaker drivers. This battery supports around 8 hours of continuous music playback and an extended standby time of approximately 20 days on a full charge. The headband style houses the internal electronics and the 40mm drive units, with onboard control buttons for managing volume, calls, and playback. The hybrid vocalism principle is employed in its audio reproduction system.

Size and Practical Fit

The key specified size is the 40mm drive unit used in each earcup. This driver size is designed to deliver sound across the stated 20-20000Hz frequency response range. The headband style suggests an over-ear or on-ear design intended to be worn during activities like sport or commuting. The wireless Bluetooth 4.0 connection provides an operating range of up to 10 metres, allowing practical movement away from your phone or audio source without losing connectivity.

Uses and Placement

This headset is specified for use with mobile phones, for hi-fi audio listening, and for sport. Its feature set supports these applications by combining wireless freedom, hands-free communication, and durable battery life.

Event or Professional Use

For professional or mobile scenarios, the integrated microphone enables clear hands-free calls, supported by Bluetooth profiles HSP and HFP. The wireless range allows you to move around a room or workspace while staying connected to calls or audio from your computer or phone. The control buttons provide quick management of volume and call functions without needing to handle your device directly. The A2DP and AVRCP profiles support high-quality stereo audio streaming and remote control of media playback from the headset itself.

Everyday Home Use

At home, the B570 serves as a versatile audio device for listening to music, podcasts, or the built-in FM radio (87.5-108MHz). The approximately 8-hour battery life covers extended listening sessions, and the standby time means the headset remains ready for use over multiple days with intermittent charging. The option to use the 3.5mm wired connection allows it to function with non-Bluetooth devices like older stereos, TVs, or gaming consoles, extending its usefulness in a household setting.

Benefits and Buying Value

The value of the ZEALOT B570 headset lies in its combination of wireless audio, hands-free functionality, and multi-use design. It provides a single audio solution for communication, entertainment, and active use without requiring multiple specialised devices.

Reuse and Low Maintenance

The rechargeable lithium battery is designed for repeated charging cycles, supporting daily use over time. The wireless design reduces wear and tear on physical connectors that can occur with frequent plugging and unplugging of wired headsets. Basic maintenance involves keeping the device charged and using the controls as intended; the source text does not specify complex care routines, suggesting straightforward, low-maintenance operation.
