The Bang & Olufsen Beosound A1 Gen 2 is a small, lightweight speaker that comes with Alexa built-in. It has a very sturdy build, and even comes with an IP67 rating for dust and water resistance that certifies it to be dust-tight and immersible in up to a meter of water for 30 minutes. It also has a carrying strap, letting you attach it to your bag so you can listen to music when you're on the go. It has a balanced mid-range, so vocals and lead instruments are reproduced accurately, but it struggles to produce low-bass, like many small speakers. Thankfully, its 'Beosonic' sound customization feature and EQ presets available in its companion app allow you to tweak its sound profile to your liking. Unfortunately, its battery life is very short, offering less than five hours of continuous playback on a single charge, but overall it's a suitable option if you want a portable speaker that has fantastic voice assistant support.
Our Verdict
The Bang & Olufsen Beosound A1 2nd Gen is okay for music. It has a balanced mid-range, so vocals and lead instruments sound clear and present in the mix. However, its treble range is underemphasized, so the higher frequencies of these instruments may sound dark and veiled. Also, it struggles to produce low-bass. Thankfully, there's a 'Beosonic' sound customization feature and five EQ presets in its companion app that let you customize its sound profile to your liking. Although it doesn't get very loud, it has amazing directivity thanks to its 360-degree design, resulting in an open and spacious soundstage.

- Wide and spacious soundstage.

- Has to downmix stereo content into mono.

The Bang & Olufsen Beosound A1 2nd Gen is sub-par for watching videos and movies. It has amazing directivity thanks to its 360-degree design, resulting in a wide and spacious soundstage. However, it doesn't get very loud, and it struggles to produce low bass, so you don't feel the deep thump and rumble in action-packed movie scenes. Thankfully, its mid-range is well-balanced, so dialogue sounds clear and present in the mix, though sibilants like S and T sounds may seem dark or veiled. It has low Bluetooth latency with iOS devices but high latency with Android devices, so it may not be suitable for watching videos over this connection. That said, some apps compensate for latency differently, so your results may vary.

The Bang & Olufsen A1 is a small, portable speaker with a sturdy build and removable carrying strap. Like many small speakers, it doesn't get very loud and struggles to reproduce low-bass. However, it has EQ presets and a 'Beosonic' sound customization feature, which let you adjust its sound profile to your liking.

The Bang & Olufsen Beosound A1 Gen 2 is a slightly better speaker than the Bose SoundLink Flex. The Bang & Olufsen offers a wider-sounding soundstage and comes with presets to tweak its sound to your liking. It also has fantastic voice assistant support with Alexa built-in, though it relies on your paired smartphone's Wi-Fi connection to work. That said, the Bose offers a better-balanced default sound profile and can get a bit louder. It also has a longer-lasting battery life, though this can vary depending on your usage.
Despite being different generations of the same speaker line, the Bang & Olufsen Beosound A1 3rd Gen and the Bang & Olufsen Beosound A1 Gen 2 have different strengths. In terms of sound, both speakers perform similarly. The 3rd Gen's main advantage is its superior battery life, while the 2nd Gen offers voice assistant support with built-in Alexa (though it depends on your phone's WiFi connection to work, since the speaker doesn't have WiFi support built in). Other than that, the main attraction of the 3rd Gen might be that it's the world's first Cradle to Cradle Certified® (Bronze) Bluetooth speaker, meaning it's designed to be serviced rather than replaced. If you're environmentally conscious, that's a big plus.
The Bang & Olufsen Beosound Explore and the Bang & Olufsen Beosound A1 Gen 2 are similar speakers, though they have different strengths. The Gen 2 has a better-balanced sound profile and offers outstanding voice assistant support. However, the Explore has a wider-sounding soundstage and can play stereo content without downmixing it to mono, which sounds more immersive. It also has a longer battery life, though this can depend on your usage habits, so your experience may vary.
The Ultimate Ears WONDERBOOM 2 is a better speaker than the Bang & Olufsen Beosound A1 Gen 2, though they have many different strengths. The Ultimate Ears has a more balanced sound profile out-of-the-box, and it can play stereo content without downmixing it into mono. It gets louder, with less compression present at max volume. Also, its battery lasts for close to thirteen hours on a single charge, while the Bang & Olufsen lasts less than five hours. However, the B&O has a companion app with a 'Beosonic' sound customization feature and five EQ presets, so you can tweak its sound to your liking.
Test Results
The Bang & Olufsen A1 is a small, circular speaker with a sleek design. It has a removable carrying strap, which lets you attach it to your bag. It also comes in several colors, so you can find a look that fits your style.
The Bang & Olufsen A1 is incredibly portable. It's very small and lightweight, so you can easily carry it with one hand. It also has a built-in carrying strap, letting you attach it to your bag. Since it's battery-powered, you can use it outside without worrying about plugging it into an outlet.
The Bang & Olufsen Beosound A1 2nd Gen has a great build quality. It's mostly aluminum, which feels solid, and it sits on a rubber base, so it doesn't slide around too much. It has an IP67 rating for dust and water resistance, meaning it's certified to be dust-tight and immersible in up to a meter of water for 30 minutes. Its carrying strap is also advertised as waterproof, but the speaker isn't advertised to be impact resistant, so the manufacturer suggests trying not to drop the speaker.
The Bang & Olufsen Beosound A1 has amazing controls. There are several buttons located on each side of the speaker. These let you turn the speaker on/off, adjust the volume, and connect a device over Bluetooth. You can also press the Bluetooth button for five seconds to enter TWS mode, which lets you connect two speakers over Bluetooth to form a stereo pair. There's a play/pause button that you can press twice to skip a track or three times to go back. Also, you can short-press it to accept a call or long-press it to reject a call. There's a mic mute button, which you can press quickly to activate the voice assistant or hold for five seconds to mute the microphone.
The Bang & Olufsen Beosound A1 2nd Gen also has two lights that indicate the current setting and the remaining battery life. The speaker makes a sound when it enters TWS mode and when a device connects over Bluetooth.
The Bang & Olufsen Beosound A1 2nd Gen has a passable frequency response accuracy. Using the 'Optimal' EQ preset, it has a well-balanced mid-range that can produce vocals and lead instruments accurately. However, it lacks low-bass, so you don't feel the deep thump and rumble in bass-heavy genres like EDM or hip-hop. Also, its treble range is underemphasized, so sibilants like cymbals and S and T sounds may seem dull or veiled. Thankfully, there's a 'Beosonic' sound customization feature and EQ presets featured on its companion app, so you can adjust its sound profile to your liking. For a Bang & Olufsen speaker that can produce a more extended low-bass, check out the Bang & Olufsen Beolit 20.
The Bang & Olufsen Beosound A1 2nd Gen has a decent soundstage. It has amazing directivity, so the soundstage is perceived as wide and spacious. However, unlike the Bang & Olufsen Beosound Explore and the Bang & Olufsen Beolit 20, it has to downmix stereo content into mono, which doesn't sound as immersive.
The Bang & Olufsen Beosound A1 2nd Gen has a middling dynamics performance. It doesn't get very loud, and there's quite a bit of compression present when you push it to max volume, especially in the bass range. As a result, it may not be very suitable for use in large, crowded rooms.
The Bang & Olufsen Beosound A1 2nd Gen has poor battery performance. Although it's advertised to last for eighteen hours on a charge, it lasted less than five hours in our tests. That said, battery performance can vary based on usage, so your real-world experience may vary. The Bang & Olufsen Beosound A1 3rd Gen has far superior battery performance, lasting over 24 hours in our testing.
The Bang & Olufsen Beosound A1 2nd Gen has outstanding voice assistant capabilities. It comes with Alexa built-in, which you can activate with your voice. However, since the speaker isn't Wi-Fi enabled, it relies on the Wi-Fi connection from your paired smartphone to work. That said, it has no trouble understanding your voice, even if you're far away or in a noisy environment. There's also a mic mute button if you want Alexa to stop listening to you.

Update 06/04/2021: We updated the results since the Bang & Olufsen Beosound A1 doesn't support Party Mode.

The app has five EQ presets you can choose from, which you can customize by moving a 'Sound Level Circle'. It also comes with a 'Beosonic' feature which is located next to the 'Favorite' preset, and you can use it to customize the speaker's sound to your liking, by moving around the feature's sound circle in order to make your audio sound brighter, warmer, more energetic, or more relaxed. Additionally, you can pair two Bang & Olufsen A1 2nd Gen speakers together to create a stereo pair. The app also lets you completely disable the voice assistant feature.
Update 01/20/2022: Thanks to user feedback, we identified that the Bang & Olufsen Beosound A1 does support USB Audio via its USB-C port. We've changed the test results for USB Audio from 'No' to 'Yes' and have updated the text.
The Bang & Olufsen Beosound A1 comes with a USB-C charging port which you can use to wire other devices like your laptop to the speaker, meaning you can listen to your favorite tunes via a wired connection instead of over Bluetooth when you need to.
The Bang & Olufsen A1 has impressive Bluetooth connectivity. It has supports multi-device pairing with up to two devices, and it has a remarkable Bluetooth range, so the speaker stays connected to your paired device even when it's far away. While its Bluetooth latency is low with iOS devices, it's high with Android devices, so it may not be suitable for watching videos over this connection. That said, some apps compensate for latency differently, so your experience may vary.
