Designed for WONDERBOOM speakers

The Knox Gear protective case is built specifically for Ultimate Ears WONDERBOOM and WONDERBOOM 2 portable Bluetooth speakers. It provides a dedicated hard-shell enclosure that shields the speaker during transport. Two internal accessory compartments with elastic straps keep USB cables and chargers organised alongside the speaker. A steady hand strap adds a secure carry option for everyday use.

Semi-waterproof EVA construction

The case uses hard-quality EVA material rated as semi-waterproof and shockproof to defend against splashes and impacts. Its rigid shell maintains shape under pressure inside a bag or luggage, preventing the speaker from being crushed. The smooth zipper operates reliably for quick access while keeping the interior sealed from moisture and dust during travel.

Fits WONDERBOOM and WONDERBOOM 2 only

This case is dimensioned exclusively for the Ultimate Ears WONDERBOOM and WONDERBOOM 2 models; other speaker sizes will not fit the moulded interior. Buyers who own a different portable speaker or need space for additional accessories should look for a larger or universal case. The precise fit ensures the speaker, cable and charger stay immobile during movement.

Questions about this item

Does the hard EVA shell and zipper keep the speaker dry if the case sits in a damp bag all day?

The case is described as semi-waterproof and water-resistant, with a smooth strong zipper that helps protect the Wonderboom speaker from splashes and moisture inside a bag.

What must I already own for this case to be useful?

You need an Ultimate Ears Wonderboom or Wonderboom 2 speaker, plus any USB cable and charger you want to store in the two interior elastic-strap compartments.

Will the original Wonderboom fit as securely as the Wonderboom 2 in the moulded interior?

The case is designed for both Wonderboom and Wonderboom 2 models, so either speaker fits the same interior space and accessory compartments.
