The PSB iQ2 demonstrates how advanced software integration, particularly via the BluOS platform, elevates the user experience and positions it as a serious contender in the compact high-resolution audio market.
PSB’s iQ2 shows how much a good software layer matters in a modern powered speaker. The hardware may be the attraction, but the experience begins in BluOS, the multi-room platform shared across the same corporate family. That matters because, as Sonos has found to its cost, audio products can live or die by the quality of the app that controls them. In this case, the control software feels closely integrated rather than bolted on, which gives the iQ2 a more polished impression than many rivals in the same class.
Setup is straightforward. PSB says the speakers combine amplification, a high-resolution digital-to-analogue converter and streaming in one package, with support for sources such as HDMI eARC, USB-C, optical input, Bluetooth with aptX Adaptive and a phono stage for vinyl. In practice, the BluOS Controller app makes the process feel quick: connect the speakers, let the app find them and complete a few simple configuration steps. For a product pitched as a simplified stereo system, that speed is important.
BluOS is also where the iQ2’s flexibility becomes clear. PSB describes the platform as a multi-room system that can access streaming services, personal libraries and internet radio, while also supporting high-resolution playback up to 24-bit/192kHz and integration with home-control systems such as Control4 and Crestron. The app lets users change sources, manage playback and group multiple BluOS-compatible speakers for whole-home listening. It is generally easy to navigate, but it can take a little digging to find less-used inputs and their specific settings, especially if they do not appear immediately on the home screen.
That small annoyance aside, the software is a genuine strength. It helps the iQ2 look more like a complete audio system than a pair of active bookshelf speakers. The wider iQ range, which includes the iQ1 and iQ2, is aimed at listeners who want stereo sound without separate components, and UK pricing has placed the iQ2 at $1,499, putting it in competition with well-regarded compact systems from KEF. In that context, PSB’s biggest advantage is not only the sound engineering but the fact that the everyday experience appears to have been designed with unusual care.
