Ultimate Ears EPICBOOM Portable Waterproof Bluetooth Speaker - Big

Our review of the Ultimate Ears EPICBOOM finds it best suited for listeners who want loud, bass-forward sound in a durable, portable package. The single biggest reason to buy is its combination of true 360-degree booming bass and long battery life, which makes it a reliable choice for outdoor gatherings, pool days, and multi-speaker setups. The speaker balances portability with punchy low end, and the included BOOM app adds useful customization without demanding technical know-how.

Key Features

• 360-Degree Booming Bass: A built-in woofer delivers a bass-forward stereo presentation that fills a room or backyard with rich low frequencies.
• 17 Hours of Playtime: Long battery life lets the speaker run through an entire day of events without frequent charging interruptions.
• IP67 Waterproofing: Dustproof construction and the ability to submerge the speaker in 1 m of water for up to 30 minutes make it suitable for pool, beach, or shower use.
• Customizable EQ: The BOOM app lets you tweak the sound with presets like Podcast Mode or Gaming Mode and create a custom EQ to suit different listening situations.
• PartyUp and Outdoor Boost: PartyUp pairs the EPICBOOM with other compatible models for larger sound, while Outdoor Boost optimizes playback for open-air environments.

Who It's For

The EPICBOOM is ideal for people who want a rugged, portable Bluetooth speaker with a strong low end and easy app-based tuning; it is especially good for outdoor hosts, poolside listeners, and gamers who value immersive bass. Its 180 ft range and NFC one-touch pairing make it convenient for parties where multiple devices may connect.

Those who prioritize ultra-compact size or near-perfect neutral studio sound should look elsewhere; the EPICBOOM favors punch and presence over a flat reference response, and some users may find the weight and functionality trade-offs noticeable if they need a very lightweight travel speaker.
