Review on Sharllen True Wireless Earbuds 5.0 Bluetooth | IPX7 Waterproof | Deep Bass Sports Earphones with Charging Case | Built-in Mic | iPhone/Android Compatible by Kathleen Melvin

Probably the most disappointing Revain purchase I've ever made. I bought these headphones for my daughter for Christmas. Pairing turned out to be impossible. I could only connect the right earbud to her phone. And when it did, the sound quality was absolutely pathetic. After many attempts to pair the left earbud with the right one, I had to give up as there are no actual instructions in the box. Most of the instructions were written in Chinese. And the English versions were clearly written by an inferior translator and were unintelligible. I do not recommend this product.
