Bluetooth transmitter and receiver Mozos B3 APT-X HD — wireless audio adapter (Mozos B3)

Mozos B3 APT-X HD is a compact Bluetooth transmitter and receiver designed for wireless audio streaming between non-Bluetooth devices and Bluetooth headphones, speakers or sound systems. The adapter supports the aptX HD codec for higher-resolution stereo audio and can switch between TX (transmit) and RX (receive) modes. Its low-latency performance makes it suitable for watching video and listening to music with reduced audio delay, and its small form factor allows discreet placement near TVs, audio systems or in vehicles.

Advantages

The Mozos B3 APT-X HD supports aptX HD for improved audio fidelity over standard SBC streams and offers both transmit and receive functions in one unit, simplifying connections between legacy devices and modern Bluetooth peripherals. Its low-latency mode reduces lip-sync issues when used with video sources, and the compact design and straightforward pairing process make it easy to set up. The device is compatible with common audio outputs and inputs, enabling flexible use with TVs, headphones, soundbars and car stereos.

Suitable for

• Connecting non-Bluetooth TVs or soundbars to Bluetooth headphones or speakers
• Adding Bluetooth reception to wired speakers or car stereos
• Using with Bluetooth headphones for low-latency TV or media playback
• Switching between transmitter and receiver modes for home or mobile audio setups

Key specifications

• Bluetooth codecs supported: aptX HD (with fallback to aptX and SBC as available)
• Operational modes: Transmit (TX) and Receive (RX)
• Audio channels: Stereo (left/right)
• Latency: Low-latency mode optimized for media playback
• Connectivity: Standard analog and/or digital audio interfaces for input and output (dependent on host device ports)
• Form factor: Compact adapter suitable for close placement to source or sink devices

How to use

Set the Mozos B3 to the desired mode (TX to send audio from a source device, RX to receive audio to a sink device) using the mode switch. Connect the adapter to the source or destination using the appropriate audio cable or port. Put the adapter and the target Bluetooth device into pairing mode and complete pairing according to the indicator signals. For media streaming, enable low-latency mode if available on both the adapter and the paired device to minimize delay. After initial setup, the adapter will automatically reconnect to previously paired devices when powered on and in range.

Usage recommendations

Place the Mozos B3 close to the audio source or the Bluetooth receiver for the most reliable connection and keep line-of-sight where possible to reduce interference. Use aptX HD-compatible headphones or speakers to benefit from higher-resolution audio; otherwise the stream will fall back to supported codecs. For video content, ensure both devices support low-latency operation to avoid lip-sync discrepancies. Keep the adapter firmware up to date if updates are provided by the manufacturer.
