What is it?

Our products are network music players where new electronics have been retrofitted into 20th century design items. The player connects to Bluetooth and it connects also to your home network via network cable or Wi-Fi. You can connect Bluetooth speaker systems or Bluetooth headphones and in addition also connect your wired passive Hi-Fi speakers. It is easy to switch between the different speakers. You stream audio from your devices using your apps. The devices you can use are smart phones, tablets and Windows, Mac and Linux computers. Besides your apps, you can attached a USB flash memory stick and do playback of stored music files on there. 

What are you able to do?

You can stream any audio app on your devices using Bluetooth or Airplay or UPnP.

With your Spotify premium account you can with the Spotify Connect feature use the ordinary Spotify app to stream music directly to the player without first passing through your phone.

Music files on the attached USB can be of the formats: MP3, FLAC, WAV, M4a, AAC, ALAC, DSD, MPC and some other less common digital audio formats are supported (as mentioned below the Player uses MPD – the Linux Music Player Daemon and hence supports all of MPD’s default applicable formats).

Airplay can be used for streaming from iPhones and iPads (or any device supporting Airplay) to the player. Works very well with iTunes on iOS and Windows.

This is an app free system - you don't have to download an keep track of yet another app... instead the settings like connections and the USB playback are managed through a web browser on your devices. Just enter http://player.local - if you have an Android device you must most likely use the actual IP address.

You can easily stream your music, favourite podcasts or listen to live web radio stations:

  • Stream from your favourite apps: media players, music streaming services, play downloaded music, listen to podcasts or live web radio . . .
  • Share the network music player with others - it is great to enjoy music together
  • Share the player by connecting via Bluetooth - easy streaming
  • Everyone that have a device connected to the same home network (Wi-Fi or cable) as the Network Music Player may manage the Player and do USB playback at anytime.
  • Stream the music to a Bluetooth speaker or a Bluetooth headphone. In addition you can also connect wired passive speakers and switch between all the connected speakers.
