Timekettle W4 Pro AI Interpreter Earbuds,Bidirection Simultaneous Translation,Translator Device Supporting 40 Languages,Tanslator Earbuds for Video and Phone Calls, APP Work with IOS and Android

I have used these earbuds to translate conversations with Hungarians person to person and over Whatsapp. It's like when you see something on the news from the United Nations, the person speaks in their own language, and after a short delay you hear it in English, and what I say translate to Hungarian for them. You can even watch something on YouTube in a foreign language on your phone and it translates straight to English or whatever language you want. So much more accurate and easier than when I used to rely on google translate.

I set up the device for English–Thai translation. Setup was simple and the earphones started charging as soon as I removed the plastic cover. Unfortunately, that’s where the good news ends. The English speech recognition was awful. The AI misheard me almost every time, often completely. At times the AI seemed to hallucinate and invent sentences that had nothing to do with what I actually said. It felt like a bad joke - it reminded me of those clunky pre-iPod gadgets, or the old Apple Newton with its “handwriting recognition”. When I physically pressed the earphone against my head while speaking, the English transcription improved a bit, but that already tells you how fragile the system is. The Thai translation was just as unreliable. Even at its best, quality maybe reached 60%, and that was with an active high speed fiber internet connection. Offline translation was basically a write-off. Most of the offline packs appear to be geared toward Mandarin Chinese, with other languages poorly supported or simply missing. A lot of the “translations” contained made-up words, as if the AI was guessing instead of translating. The “tutor” function is more of the same: heavily focused on Mandarin, with most other languages either not available or barely usable. My strong impression is that this device may be optimised for Mandarin–English, but it clearly does not transfer to English-Thai in any acceptable way. Given this, I find the marketing highly misleading. The product is unusable in a professional setting, and for casual use you’d be better off buying a much cheaper translator that will perform just as “well” as this one. Another option is the good old plain vanilla ChatGPT with a high translation accuracy. Bottom line: I really wanted the Timekettle W4 Pro AI to work, but I cannot justify spending over £340 on a device with such weak speech recognition and inconsistent translation quality.

Really good one 2 one, has charging issue on one headset if not fully pushed into cradle (colleague has same issue).

These Timekettle W4 Pro headphones are excellent. The translation feature works exceptionally well, especially in situations where I don't understand the language at all. I am very satisfied with their performance.

We set up the earphones for English to Korean, the setup was easy. Earphone design is good but the translation was awful. It was so inaccurate. It was like a joke routine. And that was whilst it was connected to the Internet. We tried it off-line and it was even worse. It was no more than 60% accurate , the translation was totally erroneous with ridiculous words , so we gave up and returned the unit, It was a shame. We really wanted this product but there’s no way I’m going to spend over £340 for what turns out to be very very poor quality of speech translation

Good

This kit is superb. Takes some time to get to know how to use it and I recommend practice on friends first before using it properly. For example, taking calls needs some practice on use before talking to clients or suppliers. Once over the very small hump, this thing is amazing - allowing you to talk on phone or in meetings in your own language. Take your time with speach and it works really well. Used it to help me in France doing some technical negotiations and specifications - well beyond my vocabulary - so made sure everyone know what we were doing, saved me time and money.

This device is a game changer. Really easy to use and translation is pretty accurate. Sounds quality is amazing as well. Functionality wise - this offers quite a few options like 1–1 conversations, phone call as well as media. Loving it
