Truke BTG Flex

Manufacturer: Truke

The Truke BTG Flex are true wireless earbuds designed for everyday use, offering a cable-free in-ear fit alongside a modest but practical feature set. They carry IPX5 water resistance, making them reasonably suited for workouts or light outdoor use, and include RGB lighting as a visual accent. A travel bag is included in the box, and voice prompts help guide basic interactions without needing to glance at a paired device.

On the technical side, the BTG Flex use a 13 mm driver with a frequency range of 20 Hz to 20,000 Hz and rely on passive noise reduction rather than active cancellation. Bluetooth 5.4 handles wireless connectivity with a stated range of 10 m and an audio latency of 40 ms. The earbuds deliver up to 8 hours of playback on a single charge, with the USB-C charging case extending total listening time to 52 hours; fast charging is supported, and a full charge takes around 2 hours. A four-microphone array with noise-canceling capability handles calls, and a mute function is accessible directly from the on-device control panel.

Pros
  • Bluetooth 5.4 provides a relatively current wireless standard with a 40 ms audio latency suitable for general media use
  • The charging case extends total playback to 52 hours, reducing how often the case itself needs to be recharged
  • Fast charging support means less downtime when the battery runs low
  • IPX5 water resistance offers meaningful protection against sweat and splashing during physical activity
  • A four-microphone array with noise cancellation helps maintain call clarity in noisy environments
  • A travel bag is included, adding a practical storage option out of the box
Cons
  • No active noise cancellation means background sound is only reduced passively through the earbud fit
  • Neither aptX nor AAC codecs are supported, limiting audio codec flexibility depending on the source device
  • Wireless charging is not available, requiring a wired USB-C connection every time
  • There is no ambient sound mode, so external awareness requires removing the earbuds entirely
  • Fast pairing and NFC pairing are absent, making the initial connection process more manual
  • No find device feature, which can be inconvenient if an earbud is misplaced
Who is this for?

The Truke BTG Flex are a reasonable fit for everyday listeners who want a straightforward wireless earbud experience without the complexity of advanced audio settings. The IPX5 water resistance makes them a practical option for gym sessions or outdoor activities where exposure to sweat and light rain is likely. Users who frequently take calls on the go will also benefit from the four-microphone noise-canceling setup, and those who travel or commute regularly will appreciate the 52-hour total battery life provided by the charging case, along with the included travel bag for easy carrying.

Who is this NOT for?

Users who prioritize high-fidelity audio reproduction will find the lack of advanced codec support — including AAC, LDAC, and all aptX variants — a notable limitation, as audio quality is constrained to standard Bluetooth transmission. The absence of active noise cancellation makes these earbuds a poor match for frequent travelers or commuters who need to block out loud environments such as aircraft cabins or busy public transit. Additionally, users who rely on smart convenience features like in-ear detection, ambient sound mode, or a find device function will find the feature set too limited for that kind of connected, hands-free lifestyle.

Final Verdict

The Truke BTG Flex are a no-frills set of true wireless earbuds that cover the essentials competently — IPX5 water resistance, a four-microphone noise-canceling setup for calls, and a 52-hour combined battery life that holds up well across extended daily use. Bluetooth 5.4 keeps the wireless connection current, and fast charging adds a layer of practical convenience. Where the earbuds fall short is in audio codec support and the absence of active noise cancellation, which places them outside the consideration set for audiophiles or users seeking a more feature-rich smart earbud experience. For listeners who want a durable, cable-free option suited to workouts and everyday listening without requiring advanced functionality, the BTG Flex deliver a coherent, focused package.
