I bought these to replace a very similar set of earbuds that I was very happy with, except they where touch sensor buttons and I was not sure if it was one touch to pause or one touch to turn volume up but these ear buds have a volume buttons on each one so there are no accidental touches to interrupt your listening. If you want to skip to the next song you just do two definite clicks, there is no wondering about how the touch sensor will interpret your finger touches.I've worn them for a full eight hour at work and they are light and completely comfortable the entire time. They have a nice ergonomic design that fits nice in the ear. The batteries in the earbuds have lasted the entire time that I've wanted to use them (eight hours once but a minimum of four hours every other time). These are not sound canceling, which I find good because if I turn the volume very low I can still hear my little one running around. Not that I want to hear them so much, but I can hear them when I need to and that's important.There are also 3 different ear buds to fit you better. I worked out in the gym today and I never once felt at risk of one of them falling out. When I was at work I forgot it was still in my ear then the music stopped they are so light and feel great.I must have malformed ears because most earbuds fall out occasionally, usually when I am at the gym or walking across a busy street. But the ear straps on this pair are soft and comfortable and you don't know they are there when you are wearing them. I occasionally attain what I term 'earbud nirvana' where I absolutely can't feel anything but hear great music anywaySetup is ridiculously easy. Just take at least one of them out of the case and search for A12 in your phone's Bluetooth settings. Tap on it and you're done!The case has a built-in battery that can be charged either wirelessly or using a USB-C cord. Also when using the earbuds you can charge the case so you always have it ready I charged the case wirelessly when I first received it just to top it off -- it was delivered with a 98% charge already. That was quick and efficient. I'm charging it now using the cord (for the first time since the initial charge five days ago) and that is also working well. You don’t see the wireless charging on a lot of earbuds but it makes it so convenient knowing I can just drop the case down and its ready to go when. Also on the case there a nice big display showing battery life of the case and each ear bugSignal Strength - I connect to my phone, leave my phone in the other room and can go to a maximum Bluetooth distance to disconnect. It even works with a wall between. I can even walk up the drive way to my mail box and still not disconnect and that’s almost 50ft Now I can forget my phone somewhere while listening to audio and trying to find my phone again.When I got a call, it was easy to answer and was just as easy to hear.With other earbuds when it was as windy as it was yesterday, I had to stop and find a place out of the wind so that they didn’t pick up noise that make it hard for the other person to hear me. These did just fine, even outside on a pretty windy day, while walking, the person who called could hear me with no “wind noise” being picked up causing an issue. The other person could not tell I was using earbuds and hearing them was nice and clear.
