The Realme Buds Wireless 3 Neo adopt a neckband design with an in-ear fit and stereo speakers, but do not follow a true wireless configuration — a cable connects the two earbuds. They carry an IP55 ingress protection rating, meaning they are resistant to sweat and water splashes, making them reasonably suited for physical activity. Wingtips are not included, and the overall build keeps things straightforward without additional ear stabilizers.
The Realme Buds Wireless 3 Neo use a 13.4 mm driver unit and cover a frequency range of 20 Hz to 20,000 Hz, spanning the standard audible spectrum. They rely on passive noise reduction to limit ambient sound rather than active noise cancellation, which is not supported. The drivers do not use a neodymium magnet in their construction.
The Realme Buds Wireless 3 Neo are equipped with a rechargeable battery rated at 32 hours of use, and a battery level indicator is included to keep track of remaining charge. Wireless charging is not supported, so the earbuds must be charged through a wired connection.
The Realme Buds Wireless 3 Neo connect wirelessly via Bluetooth 5.4, offering a maximum range of 10 meters and an audio latency of 45 ms, with fast pairing support for quicker device connections. NFC pairing is not available, and the earbuds do not support 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 codecs. USB Type-C is used for wired connectivity on the charging side.
The Realme Buds Wireless 3 Neo support multipoint connectivity for up to two devices simultaneously and can function as a headset for calls, backed by a mute function and voice prompts for audio feedback. Controls are handled through an in-line panel as well as a control panel placed on the device itself, keeping interaction straightforward. Fast charging is supported, which helps reduce downtime between uses. Ambient sound mode, in/on-ear detection, and a find device feature are not available, and no travel bag or temperature sensor is included.
The Realme Buds Wireless 3 Neo include a noise-canceling microphone, which helps reduce unwanted background sounds during calls or voice recordings.
