What each one can and cannot do, checked against the vendor’s own documentation. Short answer: Timekettle earbuds ($150–450 hardware) are built for face-to-face conversations while you’re out walking — that’s where they shine. Tingdong ($5.99/month software) is built for everything that happens on or through your Mac: phone calls, Zoom meetings, Netflix, YouTube, podcasts and lectures. No hardware to carry, charge or pair.

Where a row says on-device or offline: Tingdong runs recognition and translation on a dedicated streaming engine, not on your Mac. Why that is the trade we chose — model size, 60+ auto-detected languages, simultaneous pacing — is on one page: why not on-device, and why it costs money.
If your life is markets, taxis and street conversations in another country, earbuds you can wear are the right tool — buy the Timekettle. If your cross-language life happens at a desk — overseas calls, international standups, shows without subtitles — a $5.99 subscription beats a $300 gadget you have to carry, charge and remember. Try Tingdong’s free trial first: about 100 minutes of subtitles, no signup needed.
No. Tingdong is pure software: a Mac or a Windows PC, and for phone calls a Mac plus any iPhone that pairs over Bluetooth. There’s nothing to buy, charge or carry.
Timekettle earbuds are conversation devices; they’re not designed to caption media playing on your computer. Tingdong captures system audio, so any video, podcast or course on the Mac gets live translated subtitles.
Tingdong is $59.99/year (yearly plan). Timekettle hardware runs $150–450 up front, and some AI features require their own subscriptions. If you don’t need in-ear translation outdoors, the app is the smaller spend.
No — recognition and translation run in real time over the network, which is how it keeps auto-detection across 60+ languages and simultaneous pacing. Timekettle’s offline packs are the better fit for no-signal travel.
