W4 Translation Earbuds,for Global Business & Relationships,Bone-Voiceprint Sensor for Clear Voice in Noise, AI Auto-Correction,Protected Privacy with GDPR,Instant Setup via iOS/Android APP

I recently picked up the new W4 earbuds with the updated Babel AI, and they completely transformed my travel experience in Colombia. We had a personal driver who spoke very little English, and my Spanish is just as limited. We could get by with basic phrases, but it always felt like there was a wall between us. Handing a phone back and forth for translations worked in a pinch, but it wasn’t personal — and it kept our conversations short and surface-level. The moment we switched to Simu mode on the W4 earbuds, everything changed. Suddenly, we could talk naturally without breaking eye contact or passing a device around. I watched his personality come alive — we shared stories, laughed, and connected on a much deeper level. It turned a simple driver-passenger interaction into a genuine friendship. Yes, there’s a slight delay and the translation isn’t 100% perfect every time, but the accuracy is impressive, especially with Colombian dialects and local slang. Even he was surprised at how accurate. For one-on-one conversations, these earbuds are simply outstanding. They don’t just translate words — they open doors to real human connection. Highly recommend for travelers, expats, or anyone who wants to go beyond “hello” and “thank you” in another language. *Update - I got the chance to test the noise isolation tech these at a later date in a noisy outdoor cafe (other people talking and music). Unlike other translators on the market, the new Bone-Voiceprint sensors work surprisingly well. Despite the external noises, the earbuds did not turn start translation until you actually speak, blocking out unwanted noise and speech. This is huge as my previous earbuds would start translating even when I didn't say a word. This dual pickup between the bone conduction and noise canceling mic is a game-changer. In addition, the context-aware AI with Babel 2.0 also cleans up what you actually said vs what you meant to say so if you fumble your words, it does a decent job of auto-correcting. I'd buy these again in a heartbeat.

The translation is quite lagging. The buds do pick up voices well, even when there is a lot of background noise. The buds themselves, though do not stay in your ear well at all. Yet fell out a number of times. Also, the inability to translate media on the same device is just a BS way of getting you to sirens more money for the pro version. The bud caring case and charger is also very bulky and awkward on the way it splits into 2 pieces. Not sure why they wanted to change the design of earbuds and charging cases outside of unoriginal the ability to hear both the user and the other party well. Seems like this could be done well without the earbuds falling out of year ears every couple of minutes, especially if you're moving around. Otherwise, I did find the translation to be very accurate. I used then for tourism. I can speak and understand a good bit if mandarin, but because I was touring and I don't know a lot of historical terminology, I decided to get these buds to be able to understand tour guides better, rather than paying an English tour guide in China. They were good for that, for sure.

The time Kettle W-4 exceeded my expectations, by speaking clearly the AI interpreter earbuds Translate very well ,I am a happy customer, thank you.

these do not fit ears!!! not sure who's ears these fit, but they are way to big. I am a man and I know they won't fit any woman!!! It's impossible, unless you have ears canals that are the size of a middle finger! I had tried to get them to fit for over 20 minutes, and I had 2 other people try to put them in my ears. Nobody could get them in and stay. simply speaking and they'd fall out! moving or taking a step and good luck because you're probably gonna lose them! finally the over the hear holders killed my ears after 10 mins. My ears were throbbing. I tried to get them more comfortable but the over the ear just made them too tight...and the one on one feature needs you to put the ear piece on the other person so then you have to kill their ear. How they even have 4 or 5 stars blows me away. Yes they translate. Quicker than google. I've used with my family who speaks Vietnamese and they say it's about 80-85% correct. definitely quick translation but not any where near 90% accuracy. Love the magnetic box and the way it holds them and the design and the app that records and transcribes, those work great(when it picks up the voice correctly. I tried for one hour with family before traveling to Vietnam but they're so uncomfortable I won't even have a chance to check out battery life. Returning them now!

The product of its technology is very good, I have nothing to say. But the quality of the case in general leaves much to be desired, since they are grated very easily. I took them with me in the bag of my pants and my keys made some terrible scratches that even the aluminum of which the case is made is noticeable, I think for the price it costs. should be of better quality

It has the best translation but very uncomfortable to wear, plus noise cancellation is poor.

Son malísimos, no funcionan, traducen mal y tienen mal sonido, no los compren, no gasten su dinero
