Our Verdict

JBL Boombox 2

Sony GTK-XB90

The JBL Boombox 2 and the Sony GTK-XB90 have different strengths. The JBL is smaller and more portable than the Sony. It also has a better-balanced sound profile out-of-the-box, and is better-built, with an IPX7 rating for water resistance, though we don't test for this. However, the Sony is a large party speaker with multiple party features like customizable RGB lights and a microphone input.
