The Ultimate Ears WONDERBOOM 2 is a colorful speaker with a carrying strap so that you can take it with you on-the-go. It's rated IP67 for dust and water resistance and has an outdoor EQ mode to help boost its bass performance, although we don't currently test for either feature. However, it doesn't get very loud and it really lacks low-bass out-of-the-box. It also has high latency on Android as well as iOS and it doesn't support voice assistants. Still, this sturdy and lightweight speaker is a suitable choice if you want to listen to audio outdoors.

Our Verdict

6.8 Music

The Ultimate Ears WONDERBOOM 2 is alright for music. While it lacks a lot of low-bass, the rest of its sound profile is fairly well-balanced, so vocals and lead instruments sound present and detailed. It also has an outdoor EQ mode to help boost its bass, though we don't currently test for it. Since it's a 360-degree speaker, it has an outstanding soundstage. However, it doesn't get very loud.

Pros
  • Outstanding soundstage.
  • One-hand carry.
  • Bluetooth compatible.
Cons
  • Doesn't get very loud.
  • Lacking low bass.
  • Not voice activated.
6.1 Videos/Movies

The Ultimate Ears WONDERBOOM 2 is mediocre for videos and movies. It lacks a lot of low bass, which can be disappointing if you like action-packed films, and it doesn't get very loud. It also has high audio latency on iOS and Android, although some apps and devices compensate for latency differently. On the upside, it has an outdoor EQ advertised to help boost its bass reproduction. It has an outstanding soundstage, too.

Pros
  • Outstanding soundstage.
  • One-hand carry.
  • Bluetooth compatible.
Cons
  • Doesn't get very loud.
  • Lacking low bass.
  • High Bluetooth latency.
8.0 Podcasts

The Ultimate Ears WONDERBOOM 2 is great for podcasts. Although it doesn't get very loud, it has a fairly neutral mid-range so it can reproduce accurate and clear vocals. It also has a wide and natural soundstage and supports multi-device pairing.

Pros
  • One-hand carry.
  • Bluetooth compatible.
Cons
  • Doesn't get very loud.
  • Not voice activated.
3.2 Voice Assistant

The Ultimate Ears WONDERBOOM 2 doesn't have voice assistant support.

7.8 Outdoors

The Ultimate Ears WONDERBOOM 2 is good for outdoor use. This portable speaker has a great build quality with an IP67 rating for dust and water resistance. Its battery lasts just under 13 hours continuously, and it has an outdoor EQ mode, which is advertised to help bass reproduction, even though we don't currently test for this. Unfortunately, it doesn't get very loud.

Pros
  • IP67 rating for dust and water resistance.
  • Outdoor mode EQ preset.
  • One-hand carry.
  • Bluetooth compatible.
Cons
  • Doesn't get very loud.
  • Lacking low bass.

The Ultimate Ears WONDERBOOM 2 has alright controls. It has physical buttons but unfortunately, they can be a bit hard to press and they don't offer a lot of feedback. However, the volume controls are easily accessible on its front side, and there are buttons on its top side for power, pairing, and music management. There's also a button on the bottom for an outdoor EQ mode that helps to add more bass to your audio, but we don't currently test for this.

This speaker has an acceptable frequency response accuracy. Like the JBL GO 3, it lacks a lot of low bass on its default setting and won't be suited for more thumpy genres like EDM or hip-hop. The rest of the range is fairly balanced, which helps to keep vocals and lead instruments present in your mixes. If you prefer a more bass-heavy sound, you can activate 'Outdoor Mode', which is advertised to help with bass reproduction, but we don't currently test for this. If you want a speaker with a full graphic EQ for sound customization, check out the Ultimate Ears BOOM 3.

This speaker has decent dynamics. While it doesn't get as loud as speakers like the Anker Soundcore Motion+, there are minimal compression artifacts present at max volume, which ensures a fairly clean and clear sound. On the downside, it struggles to reproduce low-bass frequencies, even at a higher volume.

The Ultimate Ears WONDERBOOM 2 has an outstanding battery performance. In our test, we measured just under 13 hours of continuous battery life, which is longer than the Bose SoundLink Micro and the OontZ Angle 3, making it well-suited for long listening sessions. The speaker automatically turns itself off after 15 minutes of inactivity to save battery life. However, battery life can vary according to usage, so your experience may differ.
