Philips Fidelio AW5000/10 Wireless Speaker (Bog Gate TW10)

NB: This is not a Bluetooth speaker and it weighs 2-3 kilos.
Acclaimed as a piece of audio hardware, Philips were universally ridiculed for the rubbish control app, Airstudio+.
That's now withdrawn so you may have to search for the APK file online. Alternatives? you can use the Ethernet socket to connect to the web interface which offers the same functionality e.g. connect to Internet radio stations or Spotify (caveat: I haven't done this) Or you can connect an audio source to the 3.5mm input socket - I have done this but with mixed results, perhaps due to the quality of cable I used.
