Bush GB-5000
The Bush GB-5000 was a Bluetooth speaker sold in England in 2015. It is nearly identical to the iSound BT-5000 and the TEAC Freestyler. I'm pretty sure both of them were manufactured by SDigital in China. Their specifications include:
- SD card slot
- USB port
- Bluetooth
- FM stereo tuner
- 3.5mm Aux input
- Mic input
- Class-D amplifier (2x5 watts RMS @10% THD)
- Separate bass and treble
- Echo control
- Dimensions: 328 x 244 x 91 mm
- Mains or battery operated (6 C cells)
