Vignesh Gawali –
After my airpods pro 1 died, i wanted a similar replacement within a budget and this is a great replacement. Have been using these for a few months now and I like them so much that i bought 2 more for family and friends.
Pros:
Great battery. I have music on for 2-3 hours a day and it lasts for more than a week with the case.
Decent sound quality
Decent noise cancellation
Good build quality
Bluetooth connection is pretty good. No drops or lag.
Con:
The only con i have found so far is sometimes the sound changes when surrounding noise changes when in adaptive mode. It just feels weird and i have to pause and replay the music to get it back to normal.
Overall I feel these are much better than Airpod pro 1s and a great value ANC headphone for less than $100.

After testing the product out for a couple of days, I am in love. These fit comfortably in the ear, although they may slip out when it gets a bit dirty or when you bend down. The earbuds however have very strong magnets and won’t fall out when falling. The case is a bit chunky, but I did not mind as it still fits in my pocket. I love the opening mechanism of the case, it’s fun to fidget with.
Moving on to the sound quality, I was surprised at how good it was. The hear ID equalizer makes a great difference, and the sound is very adjustable to your liking.
The call quality is definitely an improvement from my previous earbuds, and I can easily talk in windy weather and noisy environments for the recipient to understand me.
What was a deal breaker to me was the noise canceling function during wind, as I live in a pretty windy area. You have to turn on the wind canceling on, but only once. You can barely hear the wind. I’ve heard complaints about the transparency mode, which I agree is not so great but also not needed to be honest. Extra details include:
– audio automatically stops when you take off one ear, which takes a bit like 3 seconds
– battery is amazing, I used it for a day and it has only gone down by 10%
– noise canceling amazing, can’t hear surrounding conversations around me when audio turned on
– touch function is a bit sensitive, and double/triple tapping is a bit inconvenient as it often does not pick up as separate commands.
Overall, great quality for the price but some functionality is a minor inconvenience which i can get over for this price.

I think these sound great, they are comfortable, and the quality of the ANC and voice calls is good too. I like the case design as well. Worked well in the office and the gym alike. I’m impressed with the overall experience so far after only a couple days of ownership. Will update down the road once they’ve had some miles.
***update time***
It’s about a month after purchasing and I find myself reaching for these whenever I leave the house, go to work, hit to gym, and quite often when I am at home too! Push button to open case, pop em in my ears, and boom! Instantly connected and sound is flowing! Radical!
They sound really really good out of the box. I didn’t even need to eq them or do any adjustments, they are flat out fantastic.
I found the fitment good with the largest earpieces, thanks for sending 3 different sizes.
The companion app is nice and clean, all the features work well. I can’t believe the quality of the noise cancelling, it’s really good. I wear these nearly every night in the kitchen while cooking with the hood fan running, and I’m rocking out. They don’t feel overly pressurized like many overear cans do. Transparency mode is new to me, and I think it’s really cool. I’ll use this when walking about town or if in a place and I want to stay attentive to my surroundings. Great feature and it works well, with the exception of wind noise. When it’s windy is just use normal mode.
These are also great for hands free calling. Works as intended! No complaints from the other end of the line.
Also, battery life? Awesome! I’ve charged the case once since purchase. Holy moly batman.
If I had to complain about anything…. I have 2 notes:
1) Wind and transparency mode don’t mix well. The mode boosts the wind noise. But I just go normal and it’s fine, doesn’t bother me.
2) Not great fitment in the gym sometimes. Only when I am lifting heavy and exerting a lot of force or effort, I find these start to become loose and can fall out. Barbell goodmornings are a reoccuring culprit.
Otherwise, these have been such a joy to have in my life. I’m listening to so much more music now that I have a compact hassle-free solution , and that is a joy. If you enjoy music, clean hassle-free functional performance, and great battery life, these are top notch! Also the price is fantastic, compared to a market that is inflated with brand name price tags.

Great sound, very comfortable, buds straight out of case fit my ears nicely (mine tend to smaller-regular size), stay in ears well, nice looking and great price point. Other side silicone ear fittings come with set with standard size doesn’t fit purchaser.
Amazon Kunde –
Amazing in many aspects, would not surprise me if they were best in class (at least at the sales price point of 55€ I got them at), with a few small areas of improvement.
These earphones have long battery life – even with ANC on-, sit perfectly in my ears – fine for most sports and even to hear an podcast to sleep-, and they have a good audio profile for in ears, with lots of detail.
Areas of improvement:
* at least with mine, the battery level of the case behaves highly problematic. It stays at >= 40% for a long time, and then drastically drops. Since the in ears themselfes hold so much charge, and that level still is enough to charge them up this has not been problematic for me, but so far that issue has remained. I was hoping it’d fix itself after 1-2 cycles, but at best it’s gotten slightly better. Perhaps I’ll ask for support on that.
* the ANC is okay. Nothing to write a poem about, though in fairness, it also doesn’t have any of the pressure feeling that ANC sometimes has. It reduces most environment noise, but it’s still present. Wind noise suppression doesn’t always work, seemingly depending on the angle of the wind.
* the app takes long to load (or rather it takes some time until you can interact with the settings) when you open it, which makes it a bit annoying if you want to change settings you can’t with the built in controls.
* wear detection operates a bit slow
* the case is satisfying to play with, and fits well in my – male – pockets. However the button to open it is difficult to operatewithout blocking the lid from opening – since it’s right next to each other. You can open the case without the button, though it’s not designed for that, but that’s what I usually do instead of finangling my thumb to have the right angle
* I list this as a separate point, though it is connected to the previous. The upper lid is rather large, which makes it more annoying to work with that case when it’s open, compared with competitors. Although, this might also allow for the easy insertion of the in-ears into the case, so I guess it’s a trade off.
Dave in Lincolnshire –
These are really very good! I had the 40i’s before changing to these and there’s a massive improvement in the noise cancelling. I usually walk a few miles through traffic, and other town noises, and with these I can barely hear anything now! Far superior to the 40i’s and also they have a much riser sound as well, more bass but not too heavy, and as always with this brand battery life is excellent and the fit perfectly too 👍 highly recommended.
Verissimus –
I decided to buy these True Wireless earbuds as a replacement to my Airpods Pro that I accidentally left my in my home country before flying back to North America.
I absolutely love ANKER products, but coming from an Airpods Pro, I didn’t expect much from this product when I first bought it. so my review here will mostly be related to quality of life usage and not so much on the audio aspect
Battery Life: Absolutely fantastic, over 4-5 hours of straight use before you get that beeping low battery that indicates you only have 15-20 minutes left. Then you would only have to recharge them in a case for 15-20 minutes before you can use them again for another 1-2 hours. so the claim they’re making on this product is very legit
Charging case: I’ve never fully drained the battery of the charging case as I consistently charge them every night but it doesn’t take that long to fully charge the case either. maybe 1-2 hours max?
Case durability: i’ve dropped these bad boys a couple times before on multiple hard surfaces over the last 7 months and they seem to be holding up really well with no scratches or permanent damage
Case size: coming from an airpods pro, these look significantly bulkier (1.5 times bigger) but rest assured they are still very pocketable.
Touch control: the touch control on this thing is easy to use, very easy to get used to and very reliable even when you have wet hands. the tap and/or hold function on these earbuds can be tweaked on the app settings.
Eartips/Earbuds: the one thing i dont like about this product is the provided eartips adhesiveness to the earbuds. for reference, i use the smallest eartip in the box. they are standard eartips but they do get easily detached from the earbuds and sometimes they stick in your ears when you try to remove your earbuds. please keep in mind that i come from airpods pro where the eartips suction to the earbuds are very top notch when installed and is almost impossible to be accidentally detached from the earbud.
Noise canceling: let’s just say that if an Airpods Pro cancel out 99% of the noise from a very chatty and loud environment (like a gym during peak hours), then this product cancels out maybe 94-95%. it works really well to block out most of the noise in a loud environment, but you can still hear minor inaudible noise in the background whereas the sony WF1000XM5 or Airpods Pro completely shuts out the noise.
Ambient sound: this works pretty well most of the time for a $129 headphones for you to activate to speak to someone without taking off your earbuds.
Media/Audio pause when removing earbuds: this earbud has the same feature as most high end earbuds where if you remove one earbuds while watching or listening to something, it will automatically pause the media currently being playing before hit play again on the other earbuds. however, they are not as efficient as high end Sony or Apple NC earbuds.
what I mean by this is that an Airpods Pro would immediately detect that you’ve removed one earbud and would automatically pause the media, where as the Anker Liberty 4 NC would have a 3-4 second latency delay before it notices that you’ve removed one earbud.still an amazing feature for the price tag.
waterproof: I tried once or twice to shower with these on just to see if they would hold up and they did really well with no issue whatsoever. but i don’t recommend not to shower with these on all the time. your disgusting ears also needs to be cleaned on a daily basis
Audio Quality: I am just a regular peasant who enjoys listening to audiobook and music while working out, I am not going to pretend here to tell you the mids are good, the low and highs are good when i dont even know what that all really means in the first place. all i know is that the bass is decent and i’ve never had to complain about song i’ve listened to not being punchy enough because of these earbuds. you will never have that problem as long as you’re not audiophile (most of us aren’t)
Sound Core app: i dont know how to use an equalizer but the presets they have is good enough for me to tune up my earbuds based on what i’m currently listening to
Overall: giving this product an absolute 5 stars for the Price/Value for money. definitely get it if you’re looking a for an affordable noise canceling earbuds. if anything, ANKER also has 18 months of warranty
