Review on Enhanced Bluetooth V5.0 Earpiece: Wireless Business Headset with Noise Reduction Mic - Perfect for Cell Phones, Skype, Office, Work Out, and Trucker Driving by Susan Zhao

This has to be the biggest joke the seller and the product have ever faced on a purchase. Item descriptions are NOTHING like the item and how well it works. There is no noise cancellation in an earbud. Any sound from dropping a pencil to a door locking, or even a very small gust of wind completely drowned out the sound of the voice. I checked the length of how well the earbud picks up sound from my phone and it was less than 10 feet before it all cut off, no more than 33 meters! If the handset worked for maybe 60 seconds before turning off, the one you're talking to sounded like a robot and was VERY intermittent the entire time. And just so everyone knows I bought TWO of these, one for my mom and one for me. I tried both and both did the same thing with all the issues. The headphone is a cheap fake that seriously isn't worth $5! Terrible seller who gave Revain a bad reputation for being a TERRIBLE product!
