Good

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.

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.

what a complete waste of £341. I had a business meeting in Germany and the client doesn't speak english so I needed something to help me in translation. I didn't care about the cost and went for this pro version expecting it to be pro in translation and it was an absolute disaster. The app is not very user friendly and the who unit is very bulky and looks odd when you are wearing it. You may think that if the translation is not good then I can use it for listening music and at least get something for my money but unfortunately it doesn't fit for a decent music listening. the music quality is of £20 earbuds. This is a complete fail product in all the aspects and costing fortune at the same time.

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.

I’ve spent the last few weeks putting this Timekettle W4 Pro AI Interpreter Earbuds kit through their paces, and it is genuinely impressive how far translation tech has come. This isn't just a "toy" for tourists; it’s a high-end tool designed for serious communication. • Design & Comfort: Unlike standard earbuds that plug your ear canal, these are a "proximity" open-ear design. They hook over the ear and sit just outside the canal. This is a massive win for two reasons: hygiene (crucial if you’re sharing a bud with a stranger for a 1-to-1 conversation) and situational awareness (you can still hear the room around you). They are comfortable enough to wear for hours during long meetings. • Translation Accuracy: I tested these with French, German, Spanish, and Italian. I’d estimate the accuracy is around 99%. While some have reported issues, I found that as long as your phone is positioned to hear clearly, the AI does a stellar job. For digital media (YouTube/Webinars), it’s effectively 100%. • The App & Interface: The app is the "brain" of the operation. It’s stable, intuitive, and offers several modes like "Listen & Play" for meetings and "Media Translation" for calls. The AI Memo feature is a standout, extracting key points from meetings so you don’t have to take notes while focusing on the translation. • Battery Life: The 6-hour continuous use (18 total with the case) is more than enough for a full day of international business or travel. Why Not 5 Stars? There are two main things to keep in mind before you hit "Buy": 1. The Learning Curve: This isn't exactly "plug and play." You need to practice with the different modes—especially for phone calls or technical negotiations—before using them in a high-stakes environment. 2. The Price Point: At roughly £450 (at the time of this review), this is a hefty investment. If you are a casual traveller, Google Translate might suffice. You really need to be someone who frequently handles multilingual business or lives in a multilingual environment to justify the cost. Performance Note: There is a slight delay in interpretation, but it’s very similar to working with a human interpreter. It’s natural and doesn't break the flow of a conversation once you get used to the rhythm. The Timekettle W4 Pro is a premium, well-built, and professional piece of kit. It feels like something out of science fiction. If you have the budget and a genuine need for frequent, high-accuracy translation, it’s worth every penny. However, the high price tag makes it a "specialist" tool rather than a casual accessory. Pros: • Excellent build quality and premium materials. • Hygienic open-ear design. • Highly accurate semantic segmentation and noise reduction. • Reliable offline mode for 8 major languages. Cons: • Expensive. • Requires the app to be active for most features.
