Reviews last updated: August 2026 · How we calculate this

What customers like about Ultimate Ears WONDERBOOM 2

  • Excellent, well-rounded 360-degree sound quality with improved bass performance
  • Highly portable, lightweight, and compact design featuring a convenient hanging loop
  • IP67 dustproof and waterproof rating, allowing it to survive submersion and float in water
  • Impressive battery life lasting up to 13 hours on a single charge
  • Useful 'Outdoor Boost' button that enhances treble and clarity for open-air listening
  • Stereo pairing capability to link two Wonderboom speakers together for bigger sound

What customers don't like about Ultimate Ears WONDERBOOM 2

  • Lacks smart features, including a total absence of built-in voice assistants like Alexa or Google Assistant
  • Does not feature a 3.5mm auxiliary port for wired audio connections
  • Relies on an outdated Micro-USB port for charging instead of modern USB-C
  • Maximum volume capability may feel slightly limited in very large or highly noisy outdoor environments
  • Cannot be integrated or managed via a dedicated smartphone companion app

Verdict

The Ultimate Ears WONDERBOOM 2 is an ultra-portable, cylindrical Bluetooth speaker measuring 95.3x104mm and weighing 420g, equipped with two 40mm active full-range drivers and two 46.1mm x 65.2mm passive radiators to deliver 360-degree sound across a 75 Hz – 20 kHz frequency range. Its standout features include a rugged, drop-tested body with an IP67 dustproof and waterproof rating that allows it to float, an Outdoor Boost mode that bumps maximum loudness from 86 dBC to 87 dBC, wireless stereo pairing, and a 13-hour battery life. However, it relies on an outdated Micro-USB charging port with a 2.6-hour charge time, completely lacks a companion app, equalizer customization, or physical auxiliary inputs, and distorts or loses low-bass punch at maximum volume levels.
