The Final ZE300 use an in-ear fit and are fully true wireless, with no cables or neckband involved. Each earbud weighs just 8 grams, keeping the overall form light and unobtrusive during wear. The design carries an IPX4 rating, meaning it holds up against sweat and light moisture, though it does not claim full waterproofing. Stereo speakers are present, while wingtips, RGB lighting, a UV light, and an integrated display are all absent from the design.
The Final ZE300 include both active noise cancellation and passive noise reduction, offering two approaches to limiting unwanted ambient sound during playback. The frequency response spans the full range from 20 Hz to 20,000 Hz, covering the standard audible spectrum. The earbuds do not support spatial audio, and there is no Dolby Atmos, Dirac Virtuo, or neodymium magnet driver technology present.
The Final ZE300 offer 5.5 hours of battery life per charge, with the included charging case providing an additional 11 hours, bringing the combined total to 16.5 hours. A full recharge takes approximately one hour, and the earbuds support fast charging. A battery level indicator is built in to keep users informed of remaining power. The battery is rechargeable, though wireless charging and solar charging are not supported.
The Final ZE300 connect wirelessly with a maximum Bluetooth range of 10 meters, and support the AAC codec for audio transmission. Wired charging uses a USB Type-C connection, though the earbuds do not support NFC pairing or fast pairing. On the codec side, LDAC, LDHC, aptX and all its variants — including aptX Adaptive, aptX HD, aptX Low Latency, aptX Lossless, and aptX Voice — are absent, as are Bluetooth LE Audio and Auracast.
The Final ZE300 include an ambient sound mode that lets environmental audio through when needed, along with a mute function and voice prompts for basic interaction feedback. The earbuds can be used as a headset for calls and feature a control panel placed directly on the device, though there is no in-line control panel. Fast charging is supported, and a travel bag is included in the box. In-ear detection, a find device feature, notification reading, a built-in translator, a body temperature sensor, and a camera remote shutter function are all absent.
The Final ZE300 are equipped with a noise-canceling microphone, which works to reduce background noise during calls and voice input.
