Review on 🔊 Libratone Zipp Wi-Fi Bluetooth Smart Speaker, 360° Immersive Stereo Sound with Dual Microphone Built-in, 15W Subwoofer for Enhanced Bass, 12-Hour Playtime, AirPlay 2 and Spotify Connect, Compatible with Alexa (Graphite Grey) by Prince Fratto

Libratone Zipp works great with Bluetooth, smartphones and Spotify. However, streaming internet radio over Wi-Fi is often disabled. There are also problems when two or more Bluetooth-paired smartphones are in range at the same time. Phones seem to be prioritized by the order they're paired in, not how you issue commands and streams to them. Luckily, it receives firmware updates from the internet over WiFi. I hope you read this post and the update fixes these issues. As of June 2017, this is still the best wireless speaker ever. September update: Libratone support contacted me about this review. I had a faulty router that caused internet radio streaming to drop out. Now streaming works fine. As with multiple paired smartphones; They recommend turning off Bluetooth for the smartphone that doesn't control the speaker.
