Anker Soundcore 2 IPX7 Bluetooth Speaker

"We brought this back into the lineup because the rubberized chassis and physical button layout hold up better than almost any cheap portable speaker we have evaluated. The IPX7 seal around the side port flap is tight, and the overall casing feels solid enough to toss into a backpack without worrying about scuffs."

"At just under seven inches long, it sits easily on narrow window sills, shower shelves, or car cupholders. Bluetooth 5 pairs quickly with both iOS and Android devices, and you can wirelessly pair two units together for a wider stereo soundstage if you want broader coverage outdoors."

"Our endurance testing confirmed real-world runtime very close to the claimed 24 hours at moderate volume levels. BassUp processing pushes clean low frequencies through the twin drivers without clipping, and the IPX7 rating easily survived 30 minutes submerged under water without any seal leakage."

"For a compact speaker under fifty dollars, this unit delivers better battery life and water protection than major brand competitors costing twice as much. The refurbished unit offers identical functionality to new retail stock, making it an exceptional entry-level value."
