I bought three sets of earbuds back in October 2020 to test and these were the winners. Last night I bought a second pair as my backup pair, just in case I misplace this set.After 5 months daily use of being plugged in and out of my laptop and cell phone, they are still working great.Very good sound, love listening to music with these earbuds. They work great on my work laptop (Lenovo Thinkpad) and my Android phone.I find that the flat cord is much more durable (than the skinny round cord) so that was one of my criteria when I bought this set.Works great for Zoom and Teams, and talking on the phone.The earbuds are a little long so for me it's not comfortable lying my head on my pillow. I have to move my pillow aside to make a little gap for the earbud.I like that the earbuds magnetize to each other, between the flat cord and them snapping together when I set them down I never have had to deal with the cord getting all tangled up. That's a great perk.I forgot this set came with an extension cord until my purchase last night which would have come in handy, I'll have to figure out what I did with the extension cord and check it out.Would definitely recommend.UPDATE July 3, 2021. I've been using the first pair I bought back in October 2020 for 9 months now and still working great!This is very impressive as other earbuds I've used tend to start crackling or buzzing after a couple months, but these are still working great.I transfer the cord/jack from my laptop to cell phone 8-10 times every weekday and no issues at all.I'm so pleased with these that I bought each of my work team a pair on PRIME day when they were under $16.One more feature I've started using, the cord has a volume control and also a button you can press which will stop what you're listening to, e.g. if you're listening to an Audible book you can press the button to pause instead of having to fiddle with the app.In a day and age when things are so cheaply made, it is satisfying to find a quality product. I think some businesses think they will lose out on sales if the item keeps working too long but they need to remember more people will buy your product when it's good quality and tell their friends. I bought the one set back in October and have bought 5 more sets as gifts/backup in case I misplace this one.Great product, don't hesitate to put one into your cart today!
