Pros and cons

According to our Bluetooth speaker expert

  • You hear music from every side of the speaker thanks to the 360-degree sound.
  • The speaker is dustproof and water-resistant with a design that floats, so you can easily take the speaker outside.
  • With the 15-hour battery life, you can listen to music all day long.
  • You can't charge your smartphone to the speaker, because it doesn't have a power bank.

Description

You can easily take the Ultimate Ears BOOM 4 Black with you to enjoy your favorite music anywhere. The speaker provides 360-degree sound, so you can hear sound on every side of the speaker. This way, it doesn't matter where you sit to clearly hear the music. You can also use the speaker outdoors thanks to its dustproof and water-resistance with IP67 certification. For example, on the beach or by the pool. The design of the speaker allows it to float if it accidentally falls into the water. The 15-hour battery life lets you listen to music all day. You can also hold your smartphone up to 45m away from the speaker. This gives you plenty of freedom of movement. With PartyUp, you can pair other Ultimate Ears speakers for a more powerful sound.

Good speaker if you don't need to use a hotspot.

  • Handy that it stands upright
  • Nice full sound
  • Battery can last a very long time
  • Very annoying with hotspot

After 11 years of the EU boom (1st generation) it was time for an upgrade. The new boom 4. First impression: it is a lot bigger and the build quality looks less solid. Cheaper finish. Sound is good. Fuller and more detailed than the 1st generation. But when you turn on the hotspot on your phone, the trouble starts. Then the boom 4 interferes like crazy. Very annoying. The 1st generation boom and all our other headphones and speakers do not do this. Very unfortunate. We are sending it back, because we use the speaker when we work outside the home.
