The Meizu Blus 3 adopt an in-ear fit and operate as true wireless earbuds, meaning there are no cables or wires involved in their use. They are not neckband-style earbuds and do not include wingtips. The earbuds feature stereo speakers, while water resistance is not provided.
The Meizu Blus 3 include both active noise cancellation (ANC) and passive noise reduction, addressing ambient sound through two complementary approaches. Audio is handled by a 12 mm driver unit covering a frequency range of 20 Hz to 20,000 Hz, with an impedance of 28 Ohms and a sound pressure level of 119 dB/mW. Spatial audio is supported, adding a positional dimension to the listening experience. The earbuds do not use a neodymium magnet in their driver construction.
Each earbud carries a 45 mAh rechargeable battery rated for 8.5 hours of playback under standard conditions, which drops to 5 hours when ANC is active. The 400 mAh charging case extends the total battery life to 23.5 hours, and a full charge takes 1.5 hours. A battery level indicator is included, keeping the user informed of remaining charge. Wireless charging is not supported, so the case relies solely on wired charging.
The Meizu Blus 3 connect wirelessly via Bluetooth 5.3, with a maximum range of 10 meters and an audio latency of 50 ms. Fast pairing and NFC-based pairing are not supported, and the earbuds do not include any aptX variants — including aptX, aptX HD, aptX Adaptive, aptX Low Latency, aptX Lossless, or aptX Voice — nor do they support LDAC, LDHC, or AAC codec transmission. USB Type-C is present for wired charging purposes.
The Meizu Blus 3 include an ambient sound mode for environmental awareness, a mute function, voice prompts, and headset capability for taking calls. Controls are handled through a panel placed on the device itself, while an in-line control panel is not available. Fast charging is supported, and a travel bag is included in the package. In/on-ear detection, a find device feature, and a body temperature sensor are all absent from this model.
The Meizu Blus 3 are equipped with four microphones and include noise-canceling microphone technology, which helps reduce unwanted background sound during calls and voice interactions.
