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 $4.99 subscription beats a $300 gadget you have to carry, charge and remember. Try Tingdong’s 100 free credits first; no signup needed.
No. Tingdong is pure software: a Mac and, for phone calls, 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 captions.
Tingdong is $49.99/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 60-language auto-detection and simultaneous pacing. Timekettle’s offline packs are the better fit for no-signal travel.
