Timekettle launched its W4 Pro earbuds at CES 2025, featuring real-time two-way translation for phone and video calls in 40 languages. The earbuds translate automatically with a latency of three to five seconds, enhancing cross-lingual communication without compromising voice quality. Powered by the new Babel OS, they also summarize conversations and can be used for face-to-face translations. The W4 Pro is priced at $449 and will be available for purchase soon.
