    • Very solid/compelling product in this space, may not fit your ear snuggly though.
Color: Black
Let me start out by saying that this is a very solid/compelling product in this price range. The Liberty 4 NC's do a lot of things well for it's price point. The Noise Cancelling for it's time was among the best(better than the Earfun Air Pro 4 in my experience) in class, the sound quality is decent out of the box(they offer EQ via the app if you want to tune it), battery life is superb(I can use it for hours in a single session), and the build quality is decent. I believe for it's price segment (varies throughout, but I'll pick the price point of say $60-70), it's a very strong contender and you can't go wrong with this product for the right price. However, I do have 2 qualms.. one of them is specific to me though so your mileage may vary: First, the fitting.. the shape of the earpiece does not fit my ear too well, I do not have large ears per-se, but I use the largest ear tips in order to get a better seal. Not only do I have issues with getting a proper seal in my ear canal, but they also don't seat well in my ear, as they tend to fall out more easily. I don't seem to have this issue with some other earbuds(like the Earfun Air Pro 4), but I do have this issue with the Liberty 4 NC's. I will say that it's not necessarily a deal breaker though, just an annoyance, something to watch out for as it depends on your ears. Second qualm is the mic performance is just mediocre, though it is adequate for it's price class. I don't use transparency mode very often, but they seem to work ok. I'm glad that these have a transparency mode at least. --- I also wanted to note, as I alluded to earlier, that I have both the Soundcore Liberty 4 NC and the Earfun Air Pro 4's. In my opinion, other than the fitting issue(these don't seat well in my ear, and the eartips struggle a bit to get a good seal.. perhaps due to the angle of the shape of the earbuds), the Liberty 4 NC's are a notch better as a product compared to the EAP4's, especially when it comes to Noise Cancelling. I have tested both of these in a noisy cafe, and the Liberty 4 NC's noise cancelling is noticeably superior to the Earfun Air Pro 4's. So depending on your priorities, I'd still say overall, I prefer the Liberty 4 NC's. ... show more

    • What a great earbud purchase!
Color: Navy Blue
These are the highest value for the price. I personally think they sound better than my much pricier AirPod Pro 2's. The noise cancellation is very good, maybe a notch below the Air Pods. They hold a charge well for this class, generally still going strong in the morning if I wake up with them still in. No complaints here, very happy with purchase. ... show more

    • Exceptional stereo sound - minimal noise reduction
Color: Navy Blue
Were it not for noise reduction I would have rated a solid 5 star for sound quality. Very impressive at all ranges with excellent base, mid-range and very good high end crisp treble. I've had other brands of earbuds and these exceed those in quality of sound. I've used and have several Anker brand electronic products and have ALWAYS found them to be of exceptional quality and these earbuds are no exception. They come with a nice charging case and 4 sets of ear bud tips covers which offer a good range of sizes so the buds will fit securely in your ear. And this is critical for not only optimum sound quality, but for what noise reduction they do provide - more on that later. Be sure to download the excellent Soundcore app to your phone so you can customize the features to your taste and to achieve max performance. There is even a cool test you can run with the app to test the fit of the earbuds so you can change the rubber tips to fit your ear. And it works great. I played with it a bit and every time I did not have the correct piece or I pulled the bud out slightly, the test came out negative. There are some other settings and features provided by the app including equalizer settings (I didn't end up using this feature since I didn't think it improved the sound over standard setting), and on the noise reduction, what type of noise you are trying to filter, etc. Really an excellent app so I suggest using it. The set up is minimal and the buds pair quickly with Bluetooth. I'm also quite impressed with the battery life as it is in line with that as advertised. And of course it charge with any USB C charger and comes with a USB C cable, which most of us have a zillion of by now lying around anyway. But with regard to noise reduction, I am disappointed. Perhaps this is a expectation issue but what I was expecting was when I placed the buds in my ear with NC activated, all sounds would be eliminated or at minimum reduced to virtually nothing. This is not the case or at least my experience. In various tests around the house and outside, I always heard about the same amount of noise as I would have with just earbuds in the ear muffling out sounds as they would since they are jammed in the ear canal like ear plugs. And of course I tested this with NC on and off to determine any difference and there was minimal. Driving in the car with no music playing, there was minimal difference but with music playing there for some reason seemed to be an improvement in sound with NC on vs off. So perhaps they work best when playing music and are really not intended to block out sounds with no sound other than the "white noise" the buds produce sans music?? Not sure. And I highly doubt these Anker's do a lesser job than any other earbud brand. Anyway, they do sound great playing music in the car. The real test will be in a month when I take a long international flight. If they can block out even half the engine noise I'll be a happy listener! I imagine headphone NC would work better for obvious reasons, but I simply don't have the room to carry yet another bulky item on board in my briefcase, so earbuds are my only option. For the money, I'm happy with them overall. ... show more
