LEFOR·Z Speaker Case for JBL PartyBox 320 Cover

LEFOR·Z speaker case is a tailored, bottomless dust cover and storage bag made to protect and transport JBL PartyBox 320 (and fit the PartyBox 310 more loosely) while keeping ports and controls accessible.

This lightweight, foldable cover blends protective materials with thoughtful access points and pockets so you can carry accessories and use the speaker without removing the cover. It’s a fabric-only case (no wheels or pull rod included) that secures around the speaker base with Velcro straps and preserves sound and connectivity while shielding your PartyBox from dust, scratches, and light wear during travel and storage.

How does this cover protect my JBL PartyBox during travel?

The case uses a tear-resistant polyester outer shell, padded PE cotton interlayer, and a soft velvet lining to resist abrasion and prevent surface scratches. Its bottomless design secures with Velcro straps to accommodate the speaker’s existing wheels and base while keeping bulk to a minimum.

• Three-layer construction: polyester, PE cotton, velvet lining for scratch resistance.
• Velcro base straps let you use built-in wheels without removing the cover.
• Foldable and lightweight to save trunk or storage space.

Will I be able to use ports, buttons, and the pull rod with the cover on?

Yes — the LEFOR·Z design provides multiple access windows and zipper openings so controls, charging ports, and the top pull rod remain usable. Roller-blind front and back panels roll up and secure with Velcro so you can play, charge, or adjust settings without taking off the case.

• Front and rear roller-blind panels with Velcro fasteners for quick access.
• Separate top zipper for the pull rod and top-mounted controls.
• Openings preserve sound output and connectivity while the cover is in place.

What accessories and extras can this bag hold?

Multiple pockets in varied sizes organize smaller items so accessories travel with the speaker. The layout accommodates microphones, cables, tablets, bottles, and phones to keep everything in one place for gigs or outdoor events.

• Pockets sized for up to three microphones and cable storage.
• Side compartments for water bottles, umbrellas, and small tablets.
• Interior space for chargers, phones, and portable accessories.

Which JBL models fit this cover, and how precise is the fit?

This cover is specifically sized for the JBL PartyBox 320 (dimensions: 14.2 x 13.7 x 25.5 inches) and will also fit the PartyBox 310 with a slightly looser fit. Note that the product is a cover only and does not include speaker, wheels, or pull rod—those items shown in photos belong to the speaker itself.

• Designed for JBL PartyBox 320; compatible with JBL PartyBox 310 (looser fit).
• Bottom is open with Velcro straps—no fabric base included.
• Cover-only product; speaker and accessories are not included.

Who this is for: Musicians, mobile DJs, outdoor entertainers, and audio enthusiasts who own a JBL PartyBox 320 (or 310) and want a lightweight, durable cover that lets them protect the speaker while still accessing controls, charging, and transporting accessories. It’s ideal if you need a foldable storage solution that organizes mics, cables, and personal items while keeping the speaker ready for use without full removal of the cover.
