The Ultimate Ears HYPERBOOM has a decent build quality. The top and bottom are made of hard plastic, which feels solid, and the other sides are wrapped in a tight fabric that doesn't seem like it could rip easily. Also, the built-in carrying strap feels nice and thick. It has an IPX4 rating for water resistance, though we don't test for this. Unfortunately, the weatherproof door for the input ports doesn't have a very tight seal.
The controls are middling. On top of the speaker, some buttons let you power it on/off, adjust the volume, play/pause your audio, choose between different Bluetooth sources, and play audio over the AUX or Optical inputs. You can hit both volume buttons at the same time to get audible feedback on the battery level. Also, you can hit the play/pause button twice to skip to the next track and hold it to start playing the playlists you can set in the app. However, there isn't a way to skip to the previous track.
The Ultimate Ears HYPERBOOM has decent frequency response accuracy. With its Adaptive EQ feature turned on, it reproduces balanced mid and treble ranges, so vocals and lead instruments are clear and accurate. The Adaptive EQ feature analyzes the unique acoustic characteristics of your room and optimizes audio reproduction accordingly. However, it still struggles to reproduce low-bass, which can be disappointing if you like bass-heavy genres like EDM. You can also customize its sound profile using the graphic EQ and presets in its companion app.

However, battery life can vary according to usage, so your real-world experience may be different. That said, the speaker also has a power-saving feature that turns it off after fifteen minutes if it's not connected to a power source and it's not playing audio, which can help conserve battery life.
This speaker doesn't support voice assistants.
The Ultimate Ears app is very good. It offers a graphic EQ for sound customization, and there are also three different EQ presets you can choose from: 'Bass Boost', 'Game/Cinema', and 'Podcast'. You can pair it with another HYPERBOOM speaker to create a stereo pair, or to amplify your audio across a crowded party.
This speaker has several wired inputs. There's an AUX port that lets you plug your phone directly into the speaker, as well as an Optical port and an AC cable port. The USB-A port is for charging only, and the micro-USB port is just for servicing the speaker.
