Spezi is a home speaker developed together with the Yamaha Design Lab which interacts between multiple music-playing devices. Where normally disconnecting a device and connecting to another is a common issue with wireless sound systems, this speaker allows a connection with four channels simultaneously. The volume of each channel can be adjusted by lifting the corresponding antenna, which also gives visual feedback on its volume. By overlaying channels, transitions in between songs from different devices become possible and turn the speaker into a music mixer.
