Easy to use
I bought this for a trip to Brazil. They work great. Only downsides is the delay in the actual translation and needing to have an Internet connection. Very few languages are available offline

Great translation headphones!
These headphones are great. They work exactly as described. The translations are very accurate. It is a really cool new technology. And they are very comfortable and easy to set up.

Does not work anywhere near what they advertise.
Honestly, I was surprised by how bad these are, After all the Great reviews by Amazon influencers. I am upgrading from an earlier version of Time kettle, the price was steep, but what they were promising seemed to be everything I needed. These fail Hard! Advertised as seamless, it takes 5 To 10 seconds for it to translate, getting that with my old version, no improvement with the W4 Pro. The translations are wrong over 50 percent of the time. I had it translate a Sentence 3 times, speaking the EXACT same way all 3 times, it gave me 3 different answers. I cannot trust this on my travels, one mistake like this could cost me too much. Customer Assistance with Timekettle is non existent. Will be returning these. Done with Timekettle.

Disappointing translation earbuds, not worth the hype.
The Timekettle translation earbuds were disappointing. They arrived with no real instructions, and although I eventually figured them out, the setup was frustrating. The one‑on‑one translation delay was unexpected, especially after watching the demo video, which felt misleading.

Accurate, comfortable, and helps resolve so many communication barriers!
A friend introduced us to this device after he met a polish lady. He asked my wife and I to test it and let us know what we think. My wife is from Venezuela and speaks primarily spanish. We know enough of each others languages to communicate about our daily routines. However when we try to have a deeper discussion it is hard. My wife absolutely loved them so we bought one of our own. The quality is so much better than Google Translate or cheap devices. It helps with our deeper conversations between us, conversations with her family, they are comfortable to wear, phone conversations where the other side doesn’t have to wear them, etc. She wore them to church to listen to the sermon and I followed along on screen to make sure it was accurate and it was spot on. Great device!

Mas allá de lo esperado!!
Superó ampliamente mis expectativas!! Muy fácil de usar y hace todo!! Tiene muchas opciones de cada idioma. Por ejemplo de Inglés, esta el de USA, Inglaterra, Australia, y muchos mas. Lo mismo con el español, argentino, mexicano, y 10 mas. Y asi todos los idiomas. El portugués, de Portugal y de Brasil. Increíble.Además se escucha perfecto, tiene un pequeño delay, normal, pero traduce muy bien. Hay que intentar no hablar muy rápido para que no se equivoque. Pero lo mejor es que queda todo grabado y la IA hace un resumen de las conversaciones. Y lo que me falta por descubrir!! Impresionada!!!

It is useful but not 100% accurate
I purchased two of these. In doing the translation, for instance, German to English, instead of saying something is terrible, it came back and said something is fun. This completely changes the meaning and understanding. I find the same in Spanish to English and French to English. I would say it’s achieving 90% accuracy I would expect to achieve minimally, 99% accuracy.

Muy bueno hasta el momento
Por lo que pude ver hasta el momento muy útil, cuando lo pueda poner más en marcha. Tendré una idea más firme. Por ahora excelente

I bought this to give my T1 Mini translator some protection. It does have a flaw: the vinyl material has a little dome over the T1’s activation button, but the vinyl is thick enough that it makes it hard to press the button. I actually cut out this dome to make it easier to press the button.Also, I find the price to be quite excessive for what is essentially a small single piece of transparent vinyl. It strikes me as the sort of thing that should be included with the T1 as a free item, much like the charging cable.
