FAQs & alternatives

Does a higher wattage figure automatically mean better sound?

No. Manufacturer output figures do not establish sound quality, usable volume in your garden or distortion at a chosen level.

Can these speakers be left outside?

No recommendation here supports permanent outdoor storage. IP67 or IPX7 describes a test rating, not resistance to every condition or long-term exposure.

Are the battery-hour figures guaranteed?

No. They are manufacturer-stated maxima under stated conditions. Volume, lighting, bass modes and phone charging can reduce runtime.

Also consider

  • Choose WONDERBOOM 4 when compact size and straightforward portability dominate.
  • Choose BOOM 4 for a balanced one-hand speaker and compatible-speaker grouping.
  • Choose Boom 2 or Boom 2 Plus only when their extra output and bulk fit the event.
