Experience next-generation wireless audio sharing with the Astrum BT310D Dual-Link Bluetooth 6.0 Transceiver. Featuring an advanced integrated LED display, native TF/MicroSD card MP3 playback, and dual-link support, this premium 2-in-1 transceiver lets you connect two pairs of Bluetooth headphones or smartphones simultaneously via a standard 3.5mm AUX interface.
The Astrum BT310D Dual-Link Bluetooth 6.0 Transceiver is a flagship wireless audio solution engineered to deliver ultimate connectivity across home entertainment, vehicle, and mobile setups. Utilizing the latest Bluetooth 6.0 protocol, this standalone device features intuitive 2-in-1 architecture that toggles seamlessly between Transmit (TX) and Receive (RX) configurations to bridge old-school analogue hardware with modern wireless peripherals without needing external apps or software.
Standout hardware engineering introduces true Dual-Link wireless sharing. While operating in Transmit (TX) Mode, you can pair two independent sets of Bluetooth headphones or speakers to the same 3.5mm AUX source simultaneously, allowing two individuals to enjoy movies, late-night gaming, or travel entertainment together. Swapped into Receive (RX) Mode, it connects two smartphones at once to your vintage car dashboard or home amplifier, giving two users shared playback authority to alternate music and handle incoming calls on the fly.
The onboard high-visibility LED display screen completely eliminates pairing guesswork by rendering real-time notifications, active mode indicators, and the literal names of your currently connected devices. For complete untethered independence, the built-in TF/MicroSD card slot supports direct MP3 file playback (up to 32GB, cards sold separately), transforming the transceiver into a pocket-sized digital music player that requires no cellular signal or smartphone source. Recharging swiftly via a universal USB-C port, the BT310D provides cutting-edge, low-latency audio sharing for your daily digital layout.
