A little backstory - I had purchased a couple cheap sets or wireless earbuds from Walmart and Target. Both about $20. The Walmart ones had a longer battery life (about 4 hours listening time), the Target ones were more comfortable (once i realized I had been wearing them upside-down - oops), but only lasted about 2 hours and kept falling out of my ears. Neither set were noise cancelling. I work 12 hours shifts and have be around people that are constantly talking or just otherwise making very annoying sounds, so I needed a set to block out surrounding noise, but I also needed a long battery life so I didn't constantly have to recharge them.After a lengthy Amazon search, I settled on these little babies. (add heavenly angelic music) THESE EARBUDS ARE AMAZING!!I've been using them at work for the last week, off and on, not really paying attention to how long they have been playing, but I wasn't getting a 'low battery' message. I would just put them in the case at the end of the day to charge. After a few days, the case still said it had over 80% charge.So last night, I wanted to see how long they would last. I put the earbuds in just before 7pm. I would make short little stops for a minute, to answer the phone or because they cut out a little when I go down to the break room, and I stopped for about 30 minutes to take lunch, (and give my ears a little break). I didn't get a low battery notification until almost 6am!! And that was only on the left one (seems like that one is always a little more run down than the right one, charge wise). That's over 10 hours of use!I put them in the case right away, and about an hour later they were already about half way charged.Details - The sound quality is superb! Much better than the Walmart ones.They are super comfortable for long periods of time - you just have to make sure that you have them in well. There is a little notch at the top that could irritate that little flap in the front of your ear if it isn't in properly. I would take a star away for the noise cancelling. In order to really block out surrounding noise (people talking) you have to make sure they are in really tightly. The only problem with that is, when you are walking, you can actually hear your footsteps thudding in your ears, and if you are chewing something - all i can say is wow. Echo city. For the most part I just do what I did before, and just turn the volume up :) But its nice to know that as long as I'm just sitting quietly, I can jam them in if I need to.As others have stated, the lid on the case seems kinda flimsy, like if you are not careful it might break off. But I LOVE LOVE LOVE the individual charge bar per earbud. Then the case itself has the percentage of charge left before you have to plug the whole thing in. If you don't have a bud seated properly, the blue light on the earbud will blink, until you have it seated properly. (bonus!) It's kind of hard at a glance to know which is the top or bottom, front or back, I was always trying to open it on the wrong side. So i just a little dab of white out on the top where it opens, just to make my life a little easier.The 'tap' feature seems more intuitive to me than the other buds I've tried too. Tap either bud once to stop/pause playback. Double tap the left to lower the volume, double tap the right to raise the volume. Hold the left to go back a track, hold the right to go to the next track. I haven't used the earbuds for phone calls yet, so I don't know how they work for that, or how they sound to the person on the other end of the call.Other than that, these are fantastic earbuds for the $30 I paid.Highly recommended.You have to try these!!* Update - I've run the battery on the earbuds down to the 'low battery' alert about 4 times (which is pretty much 10 continuous hours each time) since I first charged the case, over a week ago... plus using them for shorter times in between. The case is currently at 48% from its original charge! I have yet to recharge the case. That's amazing!!
