The Gizmore Gizbud 870 uses an in-ear fit and operates as a fully true wireless design with no cables or neckband. It carries an IPX4 ingress protection rating, meaning it is sweat resistant and can handle light moisture during use. The earbuds feature stereo speakers for two-channel audio output, while wingtips, RGB lighting, a UV light, and a display are not included in this model.
The Gizmore Gizbud 870 covers a frequency range of 20 Hz to 20,000 Hz and relies on passive noise reduction to limit ambient sound, as active noise cancellation is not supported. The earbuds do not include a neodymium magnet, and there is no support for spatial audio, Dolby Atmos, or Dirac Virtuo audio processing.
The Gizmore Gizbud 870 offers 7 hours of battery life per charge, with the included charging case extending total playback to 23 hours. The rechargeable battery fully charges in 1.5 hours, and a battery level indicator is present to help users keep track of remaining power. Wireless charging and solar power are not supported on this model.
The Gizmore Gizbud 870 connects wirelessly via Bluetooth 5.4 with a maximum range of 10 meters, and supports the AAC codec for audio transmission. It charges through a USB Type-C port, though wireless charging is not available. Fast pairing and NFC pairing are not supported, and the earbuds do not include any aptX variants, LDAC, LDHC, LE Audio, or Auracast functionality.
The Gizmore Gizbud 870 supports fast charging and can function as a headset, making it usable for calls in addition to audio playback. Controls are placed on the device itself rather than an in-line panel, and voice prompts are included to assist with navigation. A mute function is also available, and a travel bag comes in the box. The earbuds do not offer ambient sound mode, in-ear detection for auto-pause, a find device feature, notification reading, a temperature sensor, or a camera remote shutter function.
