The Baseus M2s Pro follow a true wireless, in-ear design with no cables or neckband connecting the two earbuds. They carry a sweat-resistant rating, making them reasonably suited for light physical activity. Each earbud houses a stereo speaker, and no wingtips are included for additional ear stability.
The Baseus M2s Pro support both active noise cancellation and passive noise reduction, addressing unwanted ambient sound through two complementary approaches. The frequency response spans the full standard audible range of 20 Hz to 20,000 Hz. The drivers do not use a neodymium magnet.
The Baseus M2s Pro are equipped with a rechargeable battery offering 7 hours of playback per charge, with the charging case extending total usage to 28 hours. A full charge takes 1.5 hours, and the earbuds include a battery level indicator so remaining power is easy to check at a glance. Wireless charging is not supported, so the case relies on a wired connection for recharging.
The Baseus M2s Pro connect wirelessly via Bluetooth 5.4, covering a maximum range of 10 meters, and use USB Type-C for wired charging. Among audio codecs, LDHC is supported, while LDAC, AAC, and the full aptX family — including aptX, aptX HD, aptX Adaptive, aptX Low Latency, aptX Lossless, and aptX Voice — are not available. Fast pairing and NFC-based pairing are likewise absent.
The Baseus M2s Pro include an ambient sound mode for passing through environmental audio, along with a mute function and voice prompts for everyday usability. They can function as a headset for calls, and controls are handled through a panel placed directly on the earbuds rather than an in-line remote. Fast charging is supported, and a travel bag is included in the box. In-ear detection, a find-device feature, and a body temperature sensor are not part of the feature set.
The Baseus M2s Pro feature a four-microphone array with noise-canceling capability, designed to reduce unwanted background sound during calls and voice use.
