For Sale: JBL PartyBox 310 Selling my JBL PartyBox 310 in excellent condition, it’s only been used a handful of times and has been kept safely in its original packaging when not in use. Includes the original charging cable plus a UK power adapter I purchased separately, so it’s ready to go. The sound on this speaker is incredible, powerful bass, crisp highs, and perfect for parties or events. I’m only selling because I don’t get much chance to use it anymore and I’m moving to a smaller place.
