The Beats Solo Buds use an in-ear fit and are fully wireless, with no cables, neckband, or wingtips involved in the design. At just 11.4 grams, the earbuds are notably light, and they include stereo speakers for two-channel audio output. They carry an IPX4 ingress protection rating, making them sweat resistant and suitable for use during physical activity. The design omits RGB lighting, a UV light, and any built-in display, keeping the overall form straightforward and functional.
The Beats Solo Buds use an 8.2 mm driver unit and cover a frequency range of 20 Hz to 20,000 Hz, spanning the full standard audible spectrum. They rely on passive noise reduction to limit ambient sound rather than active noise cancellation, which is not supported. Dolby Atmos is available for compatible content, though spatial audio, Dirac Virtuo, and a neodymium magnet are not part of the specification for these earbuds.
The Beats Solo Buds offer 6 hours of battery life per charge, with the charging case contributing an additional 12 hours for a combined total of 18 hours. The rechargeable battery reaches a full charge in 1.5 hours, and a battery level indicator lets users keep track of remaining power. Wireless charging and solar power are not supported, so the earbuds rely solely on wired charging via the case.
The Beats Solo Buds connect wirelessly via Bluetooth 5.3 with a maximum range of 10 meters, and USB Type-C is present for wired charging. The earbuds do not support fast pairing, NFC pairing, AAC, LDAC, LDHC, or Bluetooth LE Audio, and none of the aptX codec variants — including aptX, aptX HD, aptX Adaptive, aptX Low Latency, aptX Lossless, or aptX Voice — are available. Auracast broadcast audio is also not supported, leaving standard Bluetooth as the sole wireless connection method.
The Beats Solo Buds include a practical set of features for daily use, with fast charging support, a mute function, voice prompts, and on-device controls that handle playback and call management directly from the earbuds. They can also function as a headset for calls and come with a travel bag included in the box. A find device feature helps locate misplaced earbuds, while ambient sound mode, in/on-ear detection, an in-line control panel, and a body temperature sensor are all absent from this model.
The Beats Solo Buds feature a dual-microphone setup with noise cancellation built in, helping to reduce background noise during calls and voice input.
