### ⭐⭐ Basically a wonderboom 2.
*by S***E on 7 May 2025*

It's basically a wonderboom 2 the only difference is the podcast mode and outdoor mode. It's got the same sound quality and it says it lasts for up to 14 hours mine only lasted 4 hour's total rip off. Way Overpriced just to call it a wonderboom 4 it's definitely not.
