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.
