Verdict

The Bluesound Pulse Flex 2i is an ultra-compact, high-resolution wireless streaming speaker featuring a 102mm mid/bass driver and a 25mm tweeter driven by 25W of bi-amplified digital power. It delivers size-defying audio up to 24-bit/192kHz and supports dual-band Wi-Fi, Apple AirPlay 2, aptX Bluetooth 4.1, Toslink/3.5mm inputs, and full multi-room control via the BluOS app. Main advantages include exceptional audiophile-grade clarity, seamless streaming integration, and five convenient top-panel hardware preset buttons. However, major downsides include a mono-only design unless paired with a second unit, high Bluetooth audio latency, boomy lower frequencies, and the fact that true portable outdoor operation requires purchasing an expensive, optional battery pack.
