TREBLAB X5 - High-End Bluetooth Earbuds w/Beryllium Speakers - True HD Sound, Deep Bass, Best Sports Running Truly Wireless Headphones, Noise Cancelling Mic Microphone, Waterproof IPX4

I have a mixed feeling about this product. What a great design with comfortable fitting, great sound (not much during phone calls) and excellent battery life. All these good things about this buds become pointless when you make a phone call and the left earbud instantly cut out and become silence. You ending up with a Mono earbud on all phone and video calls! They claimed, "This is completely normal and was made intentionally for your security while driving or running" (see attached pic) What a bogus claim is that??? Think about it... What about when I'm not driving or running?I do not recommend these earbuds because of this design failure.

Like many other customers complained about left earbud issue, I was not an exclusion. My left earbud would even disconnect sometimes completely. I've contacted Treblab Customer Service, and let me tell you, knowing that there is somebody out there thriving to help you, and will to replace defective unit at no cost was a deal breaker for me. I love these earbuds because they deliver OUTSTANDING SOUND QUALITY, and you can call me audiophile. I am also a professional musician, I know difference between good and bad sound. Here are the steps from Customer Service that you can try to solve your issue. Good luck!I am sorry to hear you’ve had these issues with your X5 earbuds and I am here to help.If you do not hear "Connected" during the pairing process, meaning the earbud is connected, please pair the earbuds with another device.

Read to the end to know why I chose that headline.I'll start with the reason I bought my X5s: my old X2s. Those earbuds were very reliable (always connected and STAYED connected to phones, computers, etc.), had great battery life close to advertised levels and was able to produce sound quality that was very good at the price point. Noise isolation was good even when there was a lot of fast-moving air because of foam ear plugs/ends (most just come with the hollow rubber cups). Comfort suffered a bit due to their design goals, but that was expected; they stayed in my ears without any problems even when I was running/biking. However, I did have a fair amount of trouble with the left earbud "losing sync" with the right one, dropping out, etc. I knew it was likely a limitation of bluetooth at the time.I bought the X5s because after a few years I lost one of my X2 earbuds getting out of my car (so sad). I expected a similar product.I have found the X5s to be everything the X2s were, but with the dropout/bluetooth issues resolved. There is a different charging case design I do not care for; I feel like the earbuds never quite fit "right" when the charging case lid is closed. However, charging works just fine. That said, the X5s are an incredible value and are impressively built earbuds.That leads me to the reason I was motivated to leave this review: the IMPRESSIVE build quality of these earbuds. The expected: these earbuds have been dropped on dirt and concrete multiple times, kicked across the floor, and generally abused as part of normal use by a human, and they've held up very well. The impressive: I'm currently listening to music on these earbuds after they dried out for two days. There are no negative effects that I can hear. This is the *second* time they've been accidentally put in the wash (in a pocket), gone through the clothes washer and dryer and come out fully functional after a drying spell. I'm utterly shocked; this is certainly more than the advertised durability and I am completely impressed with the build quality of these earbuds.In all, these earbuds are an excellent value and a solid product overall. I love them!
