Pro-Ject just launched a tiny box to turn any passive speakers wireless that attaches to the binding posts, and brings them into the Sonos-rivaling WiiM ecosystem — and there's a streamer box for hi-fi amps too… but Apple users should probably pass
Pro-Ject has launched two new audio devices, the Stream Box E and Wireless Box E, designed to add wireless streaming capabilities to existing hi-fi systems through the WiiM OS ecosystem. The Stream Box E adds streaming to amplifiers, while the Wireless Box E connects directly to passive speakers via binding posts. Both support services like Spotify Connect and Tidal Connect but lack AirPlay 2, limiting their appeal for Apple users. The products position WiiM as a Sonos alternative, though Apple integration remains a key drawback.
- ▪The Pro-Ject Stream Box E is a streaming adapter for amplifiers, offering Spotify Connect, Tidal Connect, and Qobuz support.
- ▪The Wireless Box E connects to passive speakers via binding posts, enabling wireless streaming without running audio cables.
- ▪Both devices run on WiiM OS, integrating into a growing Sonos-like multi-room ecosystem.
- ▪Neither device supports Apple AirPlay 2, making them poorly suited for Apple Music or AirPlay-dependent setups.
- ▪The Stream Box E costs £159 ($200), while the Wireless Box E is priced at £199 ($270), requiring one unit per speaker.
