Verdict

The Harman Kardon Aura Studio 4 is a visually striking home speaker featuring a 130W RMS total power output split between six 40mm mid-to-high range transducers (2 x 15W) and a 5.2-inch (130mm) downward-firing subwoofer (100W) to deliver a 360-degree soundstage across a 45 Hz to 20 kHz frequency response. Its defining pros include exceptional sonic clarity, rich bass, and a distinctive transparent dome design with 324 individual crystals providing five customizable diamond-effect animated ambient lighting themes that dance to the music. However, despite being categorized alongside portable gear, it is not truly portable as it lacks a built-in battery and requires constant wall power, while also suffering from outdated Bluetooth 4.2 connectivity, a lack of advanced audio codec support, and no official companion app for EQ adjustments.
