3/8/2017. UPDATED REVIEW:I now rate these 5 stars and here's why...After posting my original review (see below) I was contacted by Anker customer service apologizing for their mediocre sound quality and offering to send me a pair of NB10 headphones to try as well as promising to send me an updated pair of the soundbuds slim once they became available.Well, I tried the NB10's and they do have more bass and sound pretty good but really they are more workout specific in that you can't simply put them in as fast and not as comfortably at least...also the battery life is about half that of the soundbuds. One of the best things I like about the soundbuds slim is that they are so small and comfortable plus the battery life is about 7hours.Anker customer service is beyond amazing! Very very good! I thought these so called "new improved" version of the soundbuds slim would be many months away but no, they showed up last week and I've been using them ever since.Ok...I'm not sure how they did it but they most definitely did something to improve the sound because now there is SO much better sound in the midtones as well as the bass. I kept my original set and did side by side comparisons and the new ones are really great!The value you get with these for basically under $30 is unmatched. I pretty much keep them around my neck all day. Once you turn these on they pair with my iPhone 7 almost instantly every time. So far, I have been very impressed with these little things and for the inexpensive price they are totally worth it and everyone should have a set of these. They are really great, really! Time will tell how they hold up but they seem well made and I'm completely satisfied and completely recommend!My ORIGINAL REVIEW on the first pair is below:After having used these new earbuds for a few days now I would tend to agree with the general consensus I'm seeing here with these earbuds in that the build quality is quite nice and the price was certainly right. I received a $6 off coupon via email which brought my price down to $23.99. At that price I cannot complain. I will keep them and use them for watching youtube videos/ Netflix and Spotify at work etc. but as for using them as my "go to" pair for running (even though they are sweat proof) I'm afraid that's a big "no go" on that. The sound quality is just not good enough. Let me say that I have many Anker products and I am a big fan of their stuff which is why I bought these in the first place but really the Bass IS lacking. I've experimented with using larger earpieces and that helped somewhat but not really good enough in my opinion. If there was some way they could increase the bass and the volume levels a fair bit I think they could be an awesome choice. Perhaps these shortcomings are a limitation of the whole small size vs bluetooth vs. battery life vs sound compromise sort of thing? Who knows? But I will hold out hope that future versions get this right, heck I'd pay $50 bucks for these if they sounded better. As for now, they are just ok, not bad but not too good either but you have to weigh the pros and cons and realize they are a $25 option... so not bad. I will also say the battery life is excellent as is the magnets holding them together around your neck when not using them...that alone is probably the best feature. I just keep them around my neck at work and can slip them on quickly when I want to listen to something.Even though I realize I pretty much just painted a mediocre review here I would still recommend them based on price point and as long as you understand they are not going to be the greatest earbuds you ever used, so go ahead and get yourself a set.UPDATE 2: A couple of things have become apparent after my first review. 1. The beauty of these lies in the convenience factor. 2. They are a good choice for watching YouTube or Netflix on your phone. Since these can just hang around your neck they're always at the ready which is really pretty useful. I still stand by what I said above... I wouldn't use them for running (I've tried) . They are good but not great sound quality. I'm waiting on the next version of these because I will bet they get better! The size and battery life are really great as is the build quality! For a $29 set of earbuds they are pretty darn good just as long as you don't expect hi end sound quality. I would also like to say Anker customer service is really something else. They go over and above to make sure you are happy. That's one reason why I always try out their products. They are great and the price point is right on target. These guys really seem to care about bringing a modern and quality product to you for a fair price. Love Anker products. Thanks.
