JBL GO4-BLACK vs — Comparison

GO4, the JBL GO4-BLACK at £39.99, is the ultra-portable entry point in this comparison, built for easy Bluetooth listening in a tiny black speaker. PBCLUB120, the JBL PBCLUB120UK at £329.00, sits much higher as a Partybox Club 120 Bluetooth Speaker designed for larger, louder social use.

The GO4 is listed as a GO 4 Ultra-Portable Pro Sound Bluetooth Speaker - Black, so its strength is compactness and low-cost wireless playback. The PBCLUB120UK is listed as a Partybox Club 120 Bluetooth Speaker - Black, positioning it for parties rather than everyday pocketable use. No wattage, battery capacity, waterproofing rating or input list is supplied in the data, but the practical capacity difference is obvious from the form factor: GO4 is for personal portability, while Partybox Club 120 is for room-filling event sound. The PBCLUB120 costs £289.01 more.

The GO4 suits buyers who want a simple Bluetooth speaker for bags, desks, kitchens, holidays or casual background listening. It is the sensible choice if budget and portability matter more than scale. The PBCLUB120UK is for gatherings, garden parties, larger rooms and users who want the visual and audio presence of a dedicated party speaker. It is over eight times the price, so it only makes sense if you will use the extra size and party-oriented design regularly.

Bottom line: choose GO4 if you want the £39.99 ultra-portable JBL Bluetooth speaker for everyday carry and casual listening / opt for PBCLUB120 if you want the £329.00 Partybox Club 120 Bluetooth speaker for bigger rooms and parties.
