Fanatic B570 Bluetooth wireless headset with hybrid drivers and memory card support for mobile use

The Zealot Fanatic B570 represents a versatile wireless audio solution designed for both music enthusiasts and mobile phone users seeking flexible connectivity options. This headband-style headset employs a hybrid vocalism principle working with 40mm drive unit speakers to deliver stereo audio across a wide frequency range. With dual connectivity through Bluetooth 4.0 wireless technology or traditional 3.5mm wired connection, it adapts to various usage scenarios while providing up to 8 hours of continuous music playback. The inclusion of memory card support for MP3 files and built-in FM radio functionality adds further media options beyond standard Bluetooth streaming.

Features and Construction

Built around practical audio technology, the B570 incorporates several specific features that define its operation and performance characteristics. The headset's construction focuses on delivering clear audio reproduction while maintaining wireless convenience through rechargeable battery power.

Material and Build

The headset utilises plastic construction for its headband design, housing 40mm drive unit speakers that deliver audio across a 20-20000Hz frequency response range. This speaker size provides balanced audio output suitable for various music genres and voice communication. The hybrid vocalism principle combines technologies to optimise sound reproduction for both music playback and phone call clarity. With 32Ω resistance and sensitivity measuring 110±5dB ±5dB, the headset maintains consistent audio performance whether used wirelessly or via wired connection.

Size and Practical Fit

Featuring a headband style design, the B570 offers adjustable fitting for different head sizes and shapes. The 40mm speaker size provides adequate audio coverage while maintaining a balanced weight distribution across the ear cups. This construction allows for extended listening sessions during the headset's 8-hour music playback capability. The wireless operation up to 10 metres provides movement flexibility within typical indoor environments, while the 3.5mm wired option ensures connectivity when Bluetooth isn't preferred or available.

Uses and Placement

The Fanatic B570 serves multiple audio purposes through its combination of wireless technology, memory card compatibility, and phone functionality. Its hybrid approach makes it suitable for both entertainment and communication applications in various settings.

Event or Professional Use

With Bluetooth 4.0 supporting A2DP, AVRCP, HSP and HFP profiles, the headset accommodates professional scenarios requiring hands-free communication. The integrated microphone and volume control facilitate clear phone conversations while the 10-metre wireless range allows movement during calls. The memory card support enables playback of stored audio files without requiring a connected device, useful for presentations or background music in work environments. The FM radio function (87.5-108MHz) provides access to broadcast content where internet connectivity may be limited.

Everyday Home Use

For domestic listening, the B570 offers flexible connectivity options including wireless Bluetooth pairing with smartphones and tablets or traditional wired connection via 3.5mm jack. The 8-hour battery life supports extended music sessions while the approximately 20-day standby time ensures the headset remains ready for use between charges. Five colour options (black, blue, brown, red, white) allow matching with personal style preferences. The headband design provides comfortable positioning for activities like computer work, television viewing, or casual music listening throughout the home.

Benefits and Buying Value

The B570 delivers practical advantages through its multiple connectivity methods and media playback options. These features combine to create a versatile audio device that adapts to different user requirements and preferences.

Reuse and Low Maintenance

The rechargeable 400mAh lithium battery supports repeated charging cycles for extended product lifespan. The memory card functionality allows reuse of existing MP3 collections without requiring streaming services or internet access. The FM radio provides ongoing access to broadcast content without data usage or subscription costs. Both wireless and wired connection options ensure the headset remains functional even if Bluetooth technology evolves or isn't available on future devices.
