The Bang & Olufsen Beoplay Eleven use an in-ear fit and are fully true wireless, meaning there are no cables or cords involved. They weigh 12 g and do not include a neckband or wingtips, keeping the design minimal and self-contained. Durability is covered by an IP57 rating, classifying them as waterproof and protected against dust ingress. Each earbud houses a stereo speaker configuration, while features such as RGB lighting, UV light, and a display are not part of the design.
The Beoplay Eleven are equipped with a 9.2 mm driver unit and cover a frequency range of 20 Hz to 22,000 Hz. They support both active noise cancellation and passive noise reduction, giving listeners two layers of isolation from ambient sound. The earbuds do not include a neodymium magnet, and there is no support for spatial audio, Dolby Atmos, or Dirac Virtuo processing.
The Beoplay Eleven carry a rechargeable battery that delivers 8 hours of playback under standard conditions, which drops to 6 hours when active noise cancellation is enabled. The included charging case extends total availability to 20 hours, and a full charge takes 1.5 hours. Wireless charging is supported, and a battery level indicator lets users keep track of remaining power. There is no solar charging capability.
The Beoplay Eleven connect wirelessly via Bluetooth 5.2 with a maximum range of 10 m, and support aptX Adaptive and AAC as their audio codecs. USB Type-C is available for wired charging. On the codec side, LDAC, LDHC, aptX, aptX HD, aptX Low Latency, aptX Lossless, and aptX Voice are not supported, nor is Bluetooth LE Audio or Auracast. Pairing options do not include fast pairing or NFC, and the earbuds operate exclusively over a wireless connection.
The Beoplay Eleven include an ambient sound mode, a mute function, voice prompts, and a find device feature, covering a solid range of everyday usability options. They support fast charging and can connect to two devices simultaneously via multipoint pairing. The earbuds function as a headset for calls and are controlled through a panel placed on the device itself, though there is no in-line control panel. A travel bag is included in the box. In/on-ear detection, notification reading, a body temperature sensor, and a built-in camera remote are not part of the feature set.
The Beoplay Eleven feature a total of six microphones, and noise cancellation is applied to the microphone input to help reduce unwanted background sound during calls and voice use.
