The 5 Models in Detail: Acoustics, Design & Everyday Suitability

Bang & Olufsen B&O Beosound A1 3. Generation in der Farbe Honey Tone an einem Sonnenschirm hängend

Beosound A1 (3rd Generation) – The Elegant All-Rounder for Travel & Desk

In its 3rd generation, the Beosound A1 represents the epitome of Scandinavian minimalism. Envisioned by Danish designer Cecilie Manz, its palm-sized, saucer-shaped cabinet crafted from pearl-blasted aluminum resembles an elegant sculpture.

Acoustic Architecture: A true two-way system comprising a 3.25-inch woofer and a 0.6-inch tweeter, driven by dual 30-watt Class D amplifiers. In its 3rd generation, the A1 achieves even greater low-end authority (64 dB SPL at 1 m) and reproduces bass down to 54 Hz with surprising precision.

Materials & Craftsmanship: Cabinet crafted from recycled polymer and solid aluminum, finished with a strap made of genuine vegetable-tanned lambskin leather.

Sustainability & Future-Proofing: The Beosound A1 (3rd Gen) is the world's first Cradle to Cradle Certified® (Bronze level) Bluetooth speaker. The battery can be easily replaced via B&O service if needed.

Ideal Applications: Suitcase, hotel room, beach, bathroom, or as a high-precision speakerphone on your conference table (thanks to 3 integrated far-field microphones).

Expert Assessment: Anyone seeking a compact solution that takes up virtually no space in a travel bag, yet acoustically emulates the volume of a small bookshelf speaker, should choose the A1. It offers by far the best size-to-sound ratio.

Beolit 20 – The Modern Icon with Deep Acoustic Foundations

The Beolit continues a design language that traces back to Bang & Olufsen's portable radios of the 1930s. The aesthetic of a refined picnic basket is deceptive: the Beolit 20 is an acoustic powerhouse.

Acoustic Architecture: A formidable configuration consisting of a 5.5-inch long-stroke woofer, three 1.5-inch full-range drivers, and two passive bass radiators. The result is an impressive frequency response reaching down to 37 Hz and volume headroom that effortlessly fills rooms up to 50 m².

Integrated Qi Wireless Charging Pad: The rubberized top surface serves simultaneously as a wireless charging station for Qi-enabled smartphones or earphones.

Craftsmanship: Robust polymer grille with an anodized aluminum tray and a supple full-grain leather carrying strap.

Ideal Applications: Living rooms, open kitchens, covered terraces, garden gatherings.

Important Practical Note: The Beolit 20 does not possess a certified IP water-resistance rating. If a summer party encounters an unexpected rain shower, the speaker should be brought indoors immediately.

Beosound Explore – The Indestructible Outdoor Companion

While the A1 exudes understated elegance, the Beosound Explore is built for demanding outdoor conditions. Its ribbed cabinet is crafted from Type II hard-anodized aluminum, hardened at the factory in Struer for scratch resistance.

Acoustic Architecture: Dual 1.8-inch full-range drivers delivering 360-degree sound projection, optimized for outdoor clarity. The bass is tuned lighter and punchier than on the A1, ensuring voices and midrange remain crisp even in windy conditions.

Operation & Durability: Rubberized base and tactile physical buttons designed for precise operation, even with thick gloves or wet fingers. A matte black aluminum carabiner is included in the box.

Battery Life: An impressive 27 hours of playtime at moderate listening levels.

Ideal Applications: Hiking, sailing trips, camping, workshop environments, or poolside relaxation.

Expert Assessment: The Explore is the rugged, uncompromising sibling of the A1. It withstands outdoor falls effortlessly; however, in a closed living room, its sound signature is slightly cooler than that of the A1.

Beosound Level – Architectural Sound Furniture with Position Sensing

Designed by renowned designer Torsten Valeur, the Beosound Level breaks away from traditional speaker forms. At just 5.6 cm thin, it resembles a fine book or a sleek art piece—yet carries the full DNA of a B&O home audio system.

Acoustic Architecture & 3-Position Versatility: Five drivers (2x 4" woofers, 1x 2" full-range, 2x 0.8" tweeters) powered by 105 watts of total amplification. Its defining feature is built-in position sensing:

Standing upright (on a sideboard): Creates a wide, direct stereo stage.

Lying flat (on a table): Automatically switches to 360-degree sound dispersion.

Wall-mounted (with optional bracket): Adjusts frequency response, utilizing the wall as an acoustic reflector.

Connectivity & Mozart Platform: The Level combines Wi-Fi (AirPlay 2, Google Chromecast, Spotify Connect) and Bluetooth. Its streaming module (Mozart) is modular, allowing for future hardware upgrades.

Ideal Applications: Elegant living areas, libraries, terraces (IP54 splash-resistant), seamless transition between wall and table.

Expert Assessment: The Level is the most versatile piece of Danish audio engineering for design purists. Those seeking heavy party bass should opt for the Beolit or A5; those desiring crystalline clarity, architectural integration, and understated luxury will choose the Level.

Frequently Asked Questions

Yes, longevity is at the heart of the B&O philosophy. For the Beosound Level, Beosound A5, and Beosound A1 (3rd Gen), the battery can be easily replaced through authorized specialist retailers.

Bluetooth-only devices (A1, Explore, Beolit 20) connect directly to your smartphone. Wi-Fi hybrids (Level, A5) stream at home in uncompromised quality via AirPlay 2 or Chromecast and can seamlessly switch to Bluetooth while on the move.

Mozart is a modular hardware platform. Because wireless connectivity standards evolve over time, the streaming module in the Beosound Level and Beosound A5 can be replaced in the future to keep your speaker current.

No. A true stereo setup (with dedicated left and right channels) requires identical acoustic hardware to prevent phase issues and timing discrepancies. Direct stereo pairing is therefore only possible between two identical models (e.g., two Beosound A1 or two Beosound A5 speakers).

However, Wi-Fi-enabled models (Beosound Level and Beosound A5) can easily be linked in a multiroom configuration using Apple AirPlay 2, Google Chromecast, or Beolink Multiroom. They will then play the same music in complete synchronization across different rooms or zones.

Yes, seamlessly. Thanks to Beolink Multiroom, the Beosound Level and Beosound A5 integrate flawlessly into the B&O ecosystem. Through interfaces such as the Beoconnect Core, even B&O heritage pieces from the 1990s or 2000s (like a Beosound 9000 or Beosound Overture) can be connected to your home network. This allows you to stream audio from your CD player or turntable wirelessly to the Beosound Level on your terrace.

A portable Bang & Olufsen speaker is not a fleeting purchase, but an investment in Danish design, exquisite craftsmanship, and decades of acoustic philosophy. With build and sound quality operating at the absolute pinnacle across all five models, the right decision simply comes down to your daily routine: Are you seeking ultimate portability for your travel bag, indestructible outdoor durability, or room-filling high-end sound for your home and garden?

My advice after more than 15 years of hands-on B&O experience: Don't let spec sheets alone guide your decision. What truly matters is where and in what scenario the speaker will be used 80% of the time.
