For outdoor gatherings, it's fantastic that you're considering a portable speaker with both quality and fun features! Within your budget, the JBL PartyBox On-The-Go is a well-regarded option. It provides strong audio performance, has Bluetooth connectivity, and includes LED lights that add a festive touch. Plus, its splash-proof feature can handle accidental splashes, although it might not withstand a heavy downpour.
Another model to consider is the Anker Soundcore Rave Neo. It delivers impressive bass, comes with customizable party lights, and offers a long-lasting battery. It's also rated IPX7, meaning it's fully waterproof, which can be quite useful if you're planning any poolside or beach events.
In terms of brands, JBL and Anker are both reliable for portable speakers and provide good value for money. You might also explore the Sony SRS-XB33, which is slightly above your price range but frequently discounted. It's known for its durability and exceptional sound quality.
Regarding waterproofing, it's generally a valuable feature for outdoor use, especially if you're in an area prone to sudden weather changes or if near pools and beaches. It can be a nice peace-of-mind feature but not strictly necessary unless you're worried about potential exposure to water.
Always check user reviews and product specifications to ensure it meets your needs before making a purchase. For further reading, sites like CNET or TechRadar often have comprehensive reviews and comparisons that can help guide your decision.
