Ultimate Ears MEGABOOM 4 20‑hour Bluetooth speaker

This portable Bluetooth speaker delivers rounded 360-degree sound and deep, room-filling bass for outdoor gatherings and home listening alike. The Ultimate Ears MEGABOOM 4 combines a larger woofer and enhanced drivers with a robust design, making it suitable for poolside parties, beach days and all-day use thanks to a long-lasting battery.

Key Points

The speaker projects sound evenly in every direction, which helps when people are moving around a garden or living room. According to the manufacturer, the MEGABOOM 4 includes an improved woofer to reinforce low frequencies while keeping mid and high tones clear. It floats in water and carries an IP67 rating, so it resists dust and temporary submersion, and it also features a drop-resistant build for everyday knocks and bumps. The wireless range extends up to 45 metres, allowing freedom to move around without losing the connection. Two useful ecosystem features are PartyUp for pairing multiple compatible Ultimate Ears speakers and simple Bluetooth connectivity for most phones and tablets. 🎵

Technical Specifications

• Name: Ultimate Ears MEGABOOM 4
• Battery life: 20 hours (according to the manufacturer)
• Waterproof rating: IP67

Advantages

Battery life and portability combine to let you play music through a full day and into the evening. The floating capability adds versatility for water-based use, and the IP67 protection gives peace of mind against spills and sand. The PartyUp feature expands the soundstage by pairing several speakers, which is practical for larger spaces or outdoor events. The tactile fabric and rubberised housing make it easy to grip and move around. 🔊

Usage Recommendations

For best results place the speaker on a stable surface away from heavy obstructions so the 360-degree dispersion can work effectively. If using multiple units, set them up evenly around the listening area with PartyUp activated through the app to create a more immersive soundfield. Consider charging the speaker overnight before a long outing to ensure the full 20-hour runtime is available. Note that while the speaker is highly water resistant and floats, prolonged exposure to salt water may require rinsing with fresh water afterwards to maintain the finish and any metal parts. 🌊

Practical Tips

Use the companion Ultimate Ears app to manage firmware updates and adjust party settings, and test Bluetooth range in your typical environment since walls or interference may reduce the effective distance. The MEGABOOM 4 is powerful but relatively large compared with pocket speakers, so it is best when you prioritise louder output and bass over ultra-compact size.
