2. Understanding IPX4 vs IP67 Waterproof Ratings

Never take an IPX4 speaker near deep water. **IPX4** only protects against light rain splashes. An **IP67 rating** guarantees that the speaker is 100% dust-tight and can survive being dropped into a swimming pool or lake up to 1 meter (3.3 feet) for 30 minutes without water entering the acoustic enclosure.

3. Multi-Speaker Pairing: Auracast vs Proprietary Protocols

Older wireless speakers used proprietary pairing systems (like JBL PartyBoost or Sony Party Connect) that only worked within the exact same brand. Modern 2026 speakers adopt **Bluetooth 5.4 Auracastβ„’**, allowing you to broadcast audio from one smartphone to multiple speakers across different brands simultaneously.
