Boult Audio Z40 Gaming

Manufacturer: Boult Audio

The Boult Audio Z40 Gaming are true wireless earbuds designed for the wireless earbuds category, offering a cable-free in-ear fit alongside RGB lighting that gives them a gaming-oriented aesthetic. The earbuds support multipoint connectivity for up to two devices simultaneously, and come with a travel bag, voice prompts, and an on-device control panel for day-to-day convenience.

On the technical side, the Z40 Gaming uses a 10 mm driver unit covering a frequency range of 20 Hz to 20,000 Hz, paired with passive noise reduction and a four-microphone array featuring noise-canceling microphone technology. Connectivity runs on Bluetooth 5.4 with AAC codec support and a stated audio latency of 40 ms, while the charging case extends total playback to 50 hours, with fast charging via USB Type-C bringing the earbuds to full charge in around 1.5 hours.

Pros
  • The charging case extends total playback to 50 hours, making extended use between wall charges practical
  • Supports simultaneous connection to two devices via multipoint pairing
  • A four-microphone array with noise-canceling capability supports clearer voice communication
  • Fast charging is supported, reducing downtime when the battery runs low
  • Comes with a travel bag included in the box, adding convenience for portability
  • RGB lighting gives the earbuds a distinctly gaming-oriented look
Cons
  • No active noise cancellation, so audio isolation depends entirely on the passive seal of the ear tips
  • Wireless charging is not supported, requiring a wired connection every time the case needs charging
  • No ambient sound mode, making it difficult to hear surroundings without removing the earbuds
  • The find-device feature is absent, offering no way to locate misplaced earbuds through the product itself
  • No water resistance rating, limiting use in wet or high-sweat conditions
Who is this for?

The Z40 Gaming is a reasonable fit for casual gamers and everyday wireless listeners who want a true wireless earbud experience with a gaming aesthetic, particularly those who value long total battery life from the charging case and the convenience of connecting to two devices at once via multipoint pairing. The inclusion of a four-microphone noise-canceling array also makes it a practical choice for users who frequently take calls or participate in voice chat sessions, while fast charging support suits those who need a quick top-up without long waiting times.

Who is this NOT for?

Users who need active noise cancellation for focused listening in noisy environments will find this product lacking, as it relies solely on passive isolation. Those who exercise outdoors or in high-sweat conditions should look elsewhere given the absence of any water or sweat resistance. Audiophiles or users invested in higher-fidelity wireless audio ecosystems will also be underserved, as advanced codecs such as LDAC, aptX, and their variants are not supported, leaving AAC as the only enhanced codec option.

Final Verdict

Its 50-hour total battery life with fast charging support and dual-device multipoint pairing stand out as genuine strengths, and the four-microphone noise-canceling array adds real value for voice communication.

Overall, the Z40 Gaming is a straightforward option for users who prioritize battery endurance, gaming aesthetics, and hands-free calling convenience over audiophile-grade sound or environmental durability.
