Yes, it is possible to stream directly from a smartphone or other Bluetooth-enabled source such as a TV to the WiiM Amp, but with some limitations.

- The WiiM Amp supports Bluetooth 5.1 and can act as a Bluetooth receiver to receive music from a Bluetooth-enabled device such as a smartphone, tablet or computer and play it through the connected speakers.
- However, it should be noted that the WiiM Amp does not act as a Bluetooth input for the direct transmission of audio from a device to the output of the amp, but rather as a receiver or transmitter for Bluetooth headsets and speakers.

You can therefore stream music from your smartphone or other Bluetooth-enabled source to the WiiM Amp, but this involves receiving the audio signals via the amp and not direct transmission to the output of the device.
