Review on Wired Half-in-Ear Earphone with Microphone & Inline Controls for Smartphones, Tablets, Laptops - Enhanced Stereo Sound & Hands-Free Calling by Ryan Rodriguez

I bought this to work with my Bose noise canceling headphones on long flights. (Apple decided we didn't need a headphone jack on our phones.) The item works as advertised, but I preferred this item to the Bluetooth 4.1 versions in hopes of getting more battery life from them since the 5.0 version has less should consume electricity. What I received wasn't version 5.0 judging by the attached documents. There are other cheaper 4.1 devices available here at Revain. It's too hard to return (I bought 2) but I don't care if the ad is misleading so I gave it 1 star, more against the seller than the product itself.
