Verdict

The Ultimate Ears MEGABOOM 4 is a rugged, cylindrical portable Bluetooth speaker featuring dual full-range drivers and two passive radiators designed to output immersive 360-degree sound with a maximum output power of 20 watts. Constructed with a minimum of 54% post-consumer recycled plastic, it boasts an IP67 dustproof and waterproof rating, floats in water, offers 1-meter (3.28 feet) drop resistance, and provides a wide wireless range of up to 45 meters (147 feet). Main pros include its exceptional 20-hour battery life utilizing modern cell technology, the integration of a long-awaited USB-C charging port, a customizable in-app graphic equalizer, and the PartyUp feature to pair with over 150 compatible Ultimate Ears speakers. However, notable cons include its inability to get exceptionally loud compared to bulkier rivals, minor low-end audio compression at maximum volume, the complete lack of a built-in microphone for voice assistants, and the absence of multi-device pairing or wired audio inputs.
