Top WLAN Speakers Ranked by Stiftung Warentest: Discover the New Leader

Stiftung Warentest’s recent review of 19 WLAN speakers highlights the Audio Pro C20 as the top performer, earning a ‘good’ rating (1.6) for sound quality and energy efficiency. While its handling is only ‘satisfactory,’ the speaker excels in audio output and connectivity options. Priced at 535 euros, it’s ideal for home use despite lacking water and dust protection. Additionally, a table of recommended Bluetooth speakers showcases various options available for different needs and budgets.

Overview of the Latest WLAN Speaker Test

Stiftung Warentest recently conducted an extensive comparison of 19 new speakers, revealing a mixed bag of results (issue 2/2025). Among the contenders, a standout WLAN box has emerged, outperforming previous models equipped with WLAN capabilities.

Introducing the Audio Pro C20: The New Test Champion

The Audio Pro C20 has been crowned the best WLAN speaker according to Stiftung Warentest. This versatile speaker can be effortlessly controlled via an app and supports music playback through WLAN, Bluetooth, or a traditional aux cable.

With an overall rating of ‘good’ (grade 1.6), the Audio Pro C20 excels in sound quality and energy efficiency. However, its handling received only a ‘satisfactory’ rating due to a lengthy startup time and subpar display quality. The user manual also leaves much to be desired. Priced at 535 euros, it offers good value considering its features.

While the Audio Pro C20 is suitable for parties, it’s important to note that the manufacturer has not specified any water or dust protection ratings. Alternatively, it serves as an excellent shelf speaker.

This speaker delivers rich audio with a maximum volume of 93 dB(A) measured at one meter. It operates solely on a power supply but boasts impressive energy efficiency. The device comes with two analog audio inputs but lacks aux or XLR connections. Although it’s not voice-controlled, the Audio Pro C20 can be managed through the manufacturer’s app or the buttons located on the speaker itself. It also supports Spotify Connect, Apple Airplay 2, and Google Guest.
