We bought the HEDDON, but unfortunately it was very disappointing. Amazon Music is not supported, or rather, it works without volume control from the smartphone and the sound is very quiet. But what's even worse is that you can only control the overall volume with the Marshall app, but you can't adjust each speaker individually and save it as a profile. It is also not possible to set a right and left speaker for stereo sound. For the hefty price of almost €200, it is definitely not recommended. Hopefully there will be a major update so that you get what you pay for. It is also not possible to play via Bluetooth on the HEDDON where Wi-Fi streaming is not available.
