The Baseus Bass 1 Plus adopts a standard earbud fit and operates as a fully true wireless design, meaning there are no cables or wires of any kind. The earbuds do not include wingtips or a neckband, keeping the form factor minimal. They feature stereo speakers for two-channel audio output, and a built-in display is present on the product. RGB lighting and UV light are not part of the design.
The Baseus Bass 1 Plus uses a 13 mm driver unit and covers a frequency range of 20 Hz to 20,000 Hz. It includes active noise cancellation (ANC) to reduce ambient sound, though passive noise reduction is not a listed feature. Spatial audio is supported, while Dolby Atmos, Dirac Virtuo, and a neodymium magnet are not part of the sound configuration.
The earbuds carry a 35 mAh battery delivering 6 hours of playback under standard conditions, while ANC mode actually extends that to 7 hours. The accompanying charging case holds a 700 mAh battery, bringing the total combined battery life to 44 hours. A full charge takes 1.5 hours, and a battery level indicator is present to keep track of remaining power. The battery is rechargeable, though wireless charging and solar charging are not supported.
The Baseus Bass 1 Plus connects wirelessly via Bluetooth 5.4 with a maximum range of 10 m and an audio latency of 60 ms. Among supported audio codecs, LDAC is available, while AAC, aptX, aptX HD, aptX Adaptive, aptX Low Latency, aptX Lossless, aptX Voice, and LDHC are all absent. Bluetooth LE Audio and Auracast are not supported, nor are fast pairing or NFC-based pairing. USB Type-C is present for wired charging, though the connection itself remains wireless only.
The Baseus Bass 1 Plus supports multipoint connectivity for up to 2 devices simultaneously and can function as a headset, with a mute function and voice prompts included for call and interaction convenience. A control panel is placed on the device itself, though there is no in-line control panel. Fast charging is supported, and a find-device feature is available to help locate the earbuds. A travel bag is included in the package. Ambient sound mode, in/on-ear detection, notification reading, a temperature sensor, and a built-in camera remote are not part of the feature set.
The Baseus Bass 1 Plus is equipped with a total of 4 microphones, and the setup includes noise-canceling microphone technology to help reduce unwanted background sound during calls or voice use.
