One Small Device, Two Ways to Go Wireless
The Astrum BT150 is a compact 2-in-1 Bluetooth transceiver. Use it in TX mode to send audio from a TV, PC or other compatible 3.5mm audio source to Bluetooth headphones, or switch to RX mode to receive music and calls from your phone through wired speakers or headphones.
2-in-1 Transmit & Receive
A simple 3-position slider switches between TX (Transmit) and RX (Receive) modes, with a shared indicator light showing pairing and connection status in either mode.
Built-In Mic for Hands-Free Calls
In RX mode, pair the BT150 with your phone to answer, reject and take calls hands-free through your connected speakers or headphones using the built-in microphone. Calling is supported in RX mode only.
Works With Almost Anything
No computer, app or operating system requirement. TX mode connects to compatible 3.5mm audio sources, while RX mode pairs with Bluetooth-enabled phones and tablets.
Small, Light, Rechargeable
At just 11g, the BT150 is easy to carry, clip on or leave connected. The built-in 150mAh battery delivers up to 5 hours in TX mode, up to 7 hours of RX music playback or up to 6 hours of RX call time. Recharge via USB-C in approximately 2 hours.
