The Story Behind W4 Pro

A Bold Step with the Open-Ear Design

You may notice that the W4 Pro earbuds have a very different design from other Timekettle earbuds, and you might be curious about why we designed them this way. This can be traced back to 2021 when our team launched the world's first bidirectional simultaneous translation earbuds, the timekettle w3, which was loved by many users. 

As a result, when we initiated the W4 Pro project, our team felt immense pressure—because we wanted to make it even better. But how? 

After numerous discussions, we decided to completely discard the traditional music earbuds concepts and treat "Translation Earbuds" as an entirely new category, which should be a device "Specifically designed to solve communication problems." Our designers tried countless ways to express the concept of "Communication." You can imagine the piles of draft paper filling up the office table. But ultimately, we got it.

Communication should be natural and smooth, so simplicity and seamlessness are the most important things! That’s how the open-ear design was born. This design allows for larger speakers, better battery life, and the comfort to wear all day long, while the long stem houses 3 mics for enhanced translation accuracy.

This innovative open-ear design allows for:

• A comfortable, lightweight fit
• A long stem with 3 mics for enhanced translation accuracy
• Larger speaker for better sound clarity

The Inspiration Behind the Dual-Tray Charging Case

At Timekettle, the concept of "Sharing" is at the heart of everything we do. We believe that communication is more than just exchanging words; it's about creating connections and experiences that bring us closer together.

The Inspiration Behind the Dual-Tray Charging Case Imagine this: two friends, each wearing one earphone, effortlessly chatting in their native languages. That’s the beauty of the W4 Pro, designed for those moments of connection. However, in our conversations with users, we learned that sharing earphones can sometimes feel a bit challenging, particularly with those we don’t know well.

We wanted to elevate that experience into something truly special. Drawing inspiration from the intimate ritual of sharing a meal, we designed the Dual-Tray Charging Case to transform the act of sharing into a warm and respectful gesture, making every connection feel memorable.
