Review on 🎧 Wireless Headphones 2021: Best Earbuds for Workouts, Sports, and Running - Sweatproof, HD Stereo, Noise Cancelling, 9 Hours Battery with Mic by Tim Hodzic

update. I really liked them and even bought a pair for my brother. He liked her too. But recently mine just stopped working. No red or blue status indicator. So I switched to another brand. My brother continues to work normally. ---- Previous Review: I'm very happy with it, but there are a few things you need to know. The button on the left ear that looks like a PLAY button is completely nonfunctional. I was sure mine was defective when I couldn't get that button to do anything. But it turns out it's just for show. The only button that does anything is the "multifunction" button on the right ear. You press and hold it to connect. Press and hold again to disconnect. Click once to play. Press once to pause. After that, the complication begins. You can use the multifunction button to answer calls and even dial the last # in the call log, but be careful. I don't know why but one day after I pressed play it dialed my last # after a few seconds so I had to explain to the answering machine that the call was wrong. Although the sound was good and the person I spoke to said I sounded good. I have no idea where the microphone is. The phone was in my pocket. I suggest scanning and enlarging the multi-function button instruction manual and then printing a copy. Learn it. There will be an exam. As far as "noise canceling" goes, I do NOT notice any noise cancellation, so I guess it's just a buzzword added the heck.
