Verdict

The Polk Audio Boom Swimmer is an ultra-portable, rugged Bluetooth speaker featuring a 1-inch (25.4mm) driver paired with a 45mm passive radiator, a 2.5-watt power output, and a frequency response of 240Hz to 16kHz. Weighing just 0.4 lbs and measuring 9.71 inches in height by 2.62 inches in width, its primary advantages include an IPX7-rated waterproof, shockproof, and dirtproof construction that allows submersion in up to 3 feet of water for 30 minutes, an 8-hour battery life with a 2-hour recharge cycle, and highly versatile mounting options via its signature flexible wrap-around tail and interchangeable suction cup base. However, its main disadvantages are that it tends to distort easily at high volume levels, lacks low-end bass power due to its small form factor, and can roll across flat surfaces if not properly secured with its attachments.
