- •The speaker automatically powers off after 15 minutes of inactivity, which can be annoying for use with continuous notifications.

Bottom Line
If you want a *durable, portable speaker* that’s built to withstand water, dust, and drops while delivering loud, clear sound outdoors, the Ultimate Ears WONDERBOOM 4 is an excellent pick. Its 360-degree soundstage and solid battery life make it a top contender for travel and poolside parties. However, if you’re a bass fanatic or need a seamless stereo pairing experience with advanced sound controls, this might not fully satisfy those needs — and some buyers find the pricing a touch on the high side. Overall, it’s a tough, big-sounding Bluetooth speaker made for an active lifestyle.
