Timekettle W4 Pro

Manufacturer: Timekettle

The Timekettle W4 Pro is a pair of true wireless earbuds designed around a distinctive open-ear fit, making them a practical choice for users who want to stay aware of their surroundings while still benefiting from a capable audio device. One of its most notable characteristics is its built-in translation feature, which sets it apart from typical earbuds in this category. The W4 Pro also comes with wingtips for a more secure fit, a travel bag for portability, and supports stereo audio playback without any RGB lighting or display elements on the earbuds themselves.

On the technical side, the Timekettle W4 Pro features a six-microphone array with noise-canceling microphone support, which contributes to clearer voice capture during calls or translation sessions. The earbuds carry an IPX4 rating for sweat resistance and connect wirelessly via Bluetooth with a maximum range of 10 meters. Battery life reaches 6 hours per charge, with the 800mAh charging case extending that total to 18 hours; a full charge takes approximately 1 hour, and fast charging is supported. Charging is handled through USB Type-C, and a battery level indicator is included. The frequency response spans 20 Hz to 20,000 Hz, and the earbuds can also function as a headset with mute control and a device-mounted control panel.

Pros
  • The open-ear fit keeps users aware of their surroundings without removing the earbuds
  • A built-in translator adds a practical layer of functionality beyond standard audio playback
  • Six microphones with noise-canceling support make for capable voice capture during calls
  • Wingtips are included to help keep the earbuds securely in place during activity
  • The charging case holds 800mAh and extends total battery availability to 18 hours
  • Fast charging support means less downtime when the battery runs low
Cons
  • No active noise cancellation or passive noise isolation, so sound from the environment is always audible
  • Bluetooth range is limited to 10 meters, which may restrict movement in larger spaces
  • Wireless charging is not supported, requiring a wired USB Type-C connection every time
  • None of the higher-quality audio codecs such as LDAC, aptX, or AAC are available
  • The earbuds lack an automatic in/on-ear detection feature, so music does not pause when removed
  • No find device feature is included, making it harder to locate misplaced earbuds
Who is this for?

The Timekettle W4 Pro is well suited to users who frequently communicate across language barriers, as the built-in translation feature makes it a practical tool for travel, international meetings, or multilingual conversations. The open-ear design is a natural fit for people who need to remain aware of their surroundings — such as commuters, office workers, or anyone who cannot afford to be acoustically isolated from their environment. Those who prioritize call clarity and voice communication will also benefit from the six-microphone array with noise-canceling support, which is well-equipped for hands-free use throughout the day. The inclusion of wingtips and a travel bag further supports an on-the-go lifestyle.

Who is this NOT for?

Users seeking an immersive listening experience will find this product limiting, as it lacks active noise cancellation, passive noise isolation, and any form of spatial or enhanced audio processing — making it a poor fit for focused music listening in noisy environments. Audiophiles or those who rely on high-fidelity wireless audio will be underserved, since none of the advanced codecs such as LDAC, aptX, or AAC are supported, which restricts audio transmission quality. The product is also not well suited to users who value smart convenience features like automatic ear detection, a find device function, or wireless charging, as none of these are available.

The Timekettle W4 Pro covers a frequency range of 20 Hz to 20,000 Hz, spanning the full extent of standard human hearing.

Final Verdict

The Timekettle W4 Pro occupies a well-defined niche within the wireless earbud category, built primarily around its built-in translation capability and open-ear design rather than conventional audio performance. Its six-microphone array with noise-canceling support and solid battery setup — including fast charging and an 18-hour total capacity with the case — make it a reliable companion for communication-heavy use throughout the day. That said, users should approach it with clear expectations: the absence of noise isolation, advanced audio codecs, and smart convenience features means it is not positioned as an all-purpose listening device. For those whose primary need is seamless voice interaction and language translation in real-world environments, the Timekettle W4 Pro delivers a focused and functional experience.
