Verdict

The Ultimate Ears Boom 2 is a cylindrical, highly durable portable Bluetooth speaker featuring improved 10-watt drivers that pump out an immersive 360-degree sound with a maximum volume level of 90 dBA. Weighing 548 grams and measuring 180mm x 67mm, this rugged device boasts an IPX7 waterproof rating (surviving immersion up to 1 meter for 30 minutes), a 15-hour rechargeable battery life with a 2.5-hour charge time via micro-USB, an extended wireless Bluetooth range of up to 100 feet (30 meters) with NFC pairing, and an integrated accelerometer for tap gesture controls. Key pros include its exceptional volume output, drop-proof build, reliable outdoor performance, and app-enabled PartyUp feature that allows linking multiple speakers for stereo sound. However, notable cons include prominent audio distortion when pushed to its maximum volume capacity, a lack of deep sub-bass frequencies, inconsistent responsiveness from the tap controls, and the use of an outdated micro-USB port instead of USB-C.
