EarFun UBOOM Bluetooth Speaker - 24W 360 Stereo Sound for Indoor

In this review of the EarFun UBOOM Bluetooth speaker, the bottom line is straightforward: it is a compact, portable option for listeners who want surprisingly full sound and strong bass without a heavy price tag. The speaker is best for people who move between indoor and outdoor use and value long battery life and waterproofing. Its combination of 24W output, DSP tuning and bass-enhancing passive radiators make it the single biggest reason to buy if you want big sound from a small package.

Key Features

• 360 Stereo Sound: Two high-sensitivity drivers plus DSP processing deliver immersive audio that spreads sound around a room rather than from a single point.
• 50% Bass Enhancement: Dual passive radiators increase low-end impact, producing fuller bass than most speakers of this size.
• Indoor & Outdoor Modes: Two selectable sound modes let you emphasize bass for enclosed spaces or increase clarity and projection for open-air listening.
• IPX7 Sweatshield Waterproofing: Fully waterproof construction means rain, splashes, or sweat are unlikely to damage the speaker, and it can be rinsed after outdoor use.
• Bluetooth 5.0 Connectivity: The updated chip offers a longer, more stable wireless range up to about 30m, with an auxiliary jack for non-Bluetooth sources.
• Long Playback: A built-in rechargeable battery supports extended listening sessions, lasting up to 16 hours on a single charge.

Who It's For

The EarFun UBOOM suits commuters, students and casual outdoor users who want a portable speaker that delivers punchy sound and reliable waterproofing for beach, poolside or campsite use. Its compact size makes it easy to fit in backpacks or carry to small gatherings while still offering a weighty low end.

Those seeking audiophile-grade fidelity, multiroom networking, or very long playtimes beyond a full day of heavy use may want to look at larger or more specialized options. If advanced Bluetooth codecs or ultra-high volumes for very large outdoor parties are essential, consider alternatives designed specifically for those needs.
