The Truke BTG Ultra are true wireless in-ear earbuds with no cables or neckband, fitting directly in the ear canal and delivering audio through stereo speakers. They carry an IPX5 rating, offering sweat resistance for use during physical activity. Wingtips are not included for additional ear stability.
The BTG Ultra use a 13 mm driver covering a frequency range of 20 Hz to 20,000 Hz, and support spatial audio for a more immersive listening experience. Passive noise isolation is present, helping to reduce ambient sound through the physical fit of the earbuds, though there is no active noise cancellation. The drivers do not use a neodymium magnet.
The BTG Ultra offer 10 hours of battery life per charge, with the charging case extending the total available playtime to 50 hours. A full charge takes 1.5 hours, and a battery level indicator is on hand to help track remaining power. The battery is rechargeable, though wireless charging is not supported.
The BTG Ultra connect wirelessly via Bluetooth 5.4 with a maximum range of 10 m and an audio latency of 40 ms. AAC codec is supported, while LDAC, LDHC, and the full range of aptX variants — including aptX, aptX HD, aptX Adaptive, aptX Low Latency, aptX Lossless, and aptX Voice — are not available. The case charges over USB Type-C, and neither fast pairing nor NFC pairing is supported.
The BTG Ultra support fast charging and can be used as a headset, with a mute function and an onboard control panel for managing calls and playback directly from the earbuds. Voice prompts provide audio feedback for device status, and a travel bag is included in the box. The earbuds do not feature ambient sound mode, in-ear detection for auto-pause, a find device function, notification reading, in-line controls, or a body temperature sensor. A one-year warranty is provided.
The BTG Ultra are equipped with four microphones and include noise cancellation on the microphone side, aimed at reducing background sound during calls and voice communication.
