The Sonos S5, also known as the ZonePlayer S5, is a compact wireless music system designed for streaming music and creating multi-room setups. It features five speakers: two tweeters, two 3-inch mid-range drivers, and a 3.5-inch woofer, all powered by dedicated Class-D amplifiers. With dimensions akin to an iPhone's depth and weight just over 9 pounds, it is both portable and capable of delivering sound quality that fills a small room. The S5 supports various streaming services like Pandora, SIRIUS, Last.fm, and Rhapsody, along with direct access to over 25,000 Internet radio stations. The system connects to your home network via Ethernet or Wi-Fi, and owners can easily control music playback using the Sonos app available for iOS and Android devices. Configuration involves a user-friendly setup wizard in the controller application, ensuring a smooth start. However, it is important to note that for a wireless setup, a ZoneBridge 100 may be needed if there are no existing Ethernet connections. While the S5 excels in connectivity and ease of use, it may not satisfy audiophiles seeking high-end sound fidelity. Its bass response may be perceived as lacking depth, especially in larger spaces, and the slight mono sound field can limit the overall audio experience. This device is positioned as an all-in-one solution for smaller environments while seamlessly integrating into a larger Sonos multi-room system.
