Verdict

The Ultimate Ears EPICBOOM is a rugged, 1.97 kg portable Bluetooth 5.2 speaker featuring a 4.6-inch mid-woofer and two 45mm active mid-high frequency transducers that deliver a 94 dB maximum sound level with 360-degree audio coverage. Its primary advantages include an exceptionally durable IP67 dustproof and waterproof design that floats in water, a long-lasting 17-hour battery life, a 55-meter wireless range, one-touch NFC pairing, and a built-in magnetic carrying strap. However, its drawbacks include a premium $350 price tag, the omission of an auxiliary port or Wi-Fi connectivity, and a lack of smart features like voice assistants, multi-room support, or phone-charging power bank functionality.
