Review on Top-Rated True Wireless Earbuds for iPhone Android: Bluetooth 5.0, 55H Playtime, Waterproof, Touch Control, Stereo Headphones with Mic by Barbara Ortega

***Update: I noticed that these headphones come with a one year manufacturer warranty. Although Revain didn't have a short return window, I contacted Enklen directly and they sent me a brand new pair. Very accommodating and very helpful. I taped the wire to both ends of the ANC to hopefully prevent it from twisting in the future. *** I really liked these headphones. It was very nice to have them on the plane to block out noisy people. Unfortunately, after 6 months of use, the left earphone stopped transmitting sound. Clearly a faulty cable, because if you wiggle the cable near the noise-cancellation box (which is really annoying as it smacks your chest when you're exercising), the sound intermittently returns to the left ear. I tried opening them but couldn't find a broken wire. The return time has expired. You would expect $40 headphones to last more than half a year. I do not recommend.
