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.

I bought a few models for comparison and had to decide on one to keep. The JBL Reflect Aero was #2. If I could keep both I would and if it was a dead tie I might have. These were the winner! Souncore Liberty 4 ANC had decent ANC but you can still faintly hear cancelled noises, it also doesn't do well with dynamic sound changes found in industrial environments, this leads to static instead of quiet. But it took #1 due to slightly better comfort, much easier seating in the ear (literally self aligning) and fully customizable touch controls. The hearing test with self programing EQ is really cool but you can get similar results with manual EQ and some practice. What did 2nd place have? Second place had superior ANC, it turned external noises off like a switch; not a trace left to hear. It was nearly an identical music experience (they sound the same) but when the music gets quiet your ears remain deaf to the outside world. The deal breaker for me: The touch controls have a few pre-set options but none of them seem to fit all my needs unless I use different settings for each ear. Fully programable touch controls and slightly better comfort would have made this so much better (Both are subjective).

Was looking for earbuds for awhile after I lost my Beats Studio Buds that I got back in 2022. I remember my grievance with those buds just being the microphone being atrociously bad but overall they were awesome. So I got these after I got the Soundcore Anker Q20 headset a couple months ago. I liked Anker enough to experiment to look at their earbuds. I love listening to loud music but I also love to play around with the settings and have transparent and noise canceling features. Needless to say, I've had these earbuds for a week now and they're absolutely phenomenal! Great sound, although at first I was a little disappointed because it was super basey and not what I wanted, but with the app they pair with it, you can change it to sound EXACTLY how you want it. Maybe not for mega enthusiasts (even thought i consider myself an enthusiast but I digress) but I think the versatility with the sound is super grand. Too muddy sounding? Change it in the equalizer. Too much treble? Lower it in the equalizer. Too loud? Well you can just lower the volume lmao. The comfort is great, even with someone like me who has big ears they manage to fit in my ears pretty good. Although I will say that in my training sessions, which are very hard and intense excercise/running bouts, they did fall out if i was really going hard or bouncing alot. But again, take this with an asterisk, because I do have humongous ears, AND my point is null since the buds DO come with extra eartips that can affect how they sit in your ear so keep that in mind. I also have to say that these are earbuds are INSANELY comfortable to wear. Im actually a person that hates headphones and stuff being in my ear because it literally puts me on the edge of hyperventilating since I feel "trapped". But these have always felt amazing to wear, especially with transparent mode. Which I'll get back to later. I will also say that I love the fact that the buds have stems like airpods that make them more easier to handle. It's also cool that if you were to lose them, them being kinda on the bigger side (at least compared to beats studio buds) makes them easier to find. I will say durability seems pretty good. I mean they are earbuds so you shouldn't have too much of a problem with them, but I HAVE dropped them twice, and I did notice minor scuffs on them after i did that. Mind you im pretty sure they landed on concrete too. So durability might not be the best? But again, we're talking about scuffs, minor ones at that. Battery life is...well...absolutely insane. At least for me. Since it gets about 4.5 or 5 hours with ANC on and it can charge fast AND the case has 40 hours of battery life, means that battery life should NEVER be a problem. In fact with me I haven't killed these buds at ALL even with ANC on. In truth, I haven't worn these longer than 3 hours, and only because I eventually do have to put the earbuds away during my training sessions so I can focus. But even then, I never had these buds go lower than 60% battery. Bluetooth is absolutely amazing. They connect fast and I have them connected to both my laptop and phone. And they both connect fast and work amazing. Going back to ANC and transparent mode, I think these buds really live up to their namesake, they LITERALLY block up to 80%-90% of sound around you! It's INSANE! I knew it was bad when I literally had a leaf blower next to my ear, LOUD ASF BTW, and I literally could not hear more than 5% of it. All I heard when I was using it was Otonke from DanDaDan lmao. So yeah ANC is excellent! Beautiful even! Transparent mode is awesome too, although I didn't hear too much of a difference, I still felt like the outside world was still pretty muted while I had it on but maybe more testing is required. But to me, transparent mode is whatever to me because I'll just take one earbud out or just take them both off. Even then like I said before, it is pretty comfortable to wear while it's on. Finally, the color. God the color. My favorite color is blue and I REALLY don't know what's going on with the color choices of laptops, headphones, earbuds, phones but they all SUCK nowadays. Literally little to no color options and it honestly sucks. What happened to the blues, greens, reds, yellows, oranges? Now it's all glossy boring stuff like black, white or, and this is gonna be a doosey...GLOSSY BLUE EHEHEHEHEHEHE. But no, color choices really suck nowadays, but these come in a very awesome blue color that I am in love with. I just wish these developers had more color options like this because it's actually one of the main reasons why I got these instead of the Liberty 4 Pros. On that note I was actually torn between these and the Pros. I ended up getting these because of the amazing price but also the color choice (because of course). But also I didn't hear there being too much of a difference with the ANC in comparison of the two, and they actually had a VERY SLIGHTLY worse battery. People are giving those praise but honestly? With the price, the color, the versatile sound options, and ANC, and the amazing look and feel? I couldn't ask for anything better. Only thing holding it back is the whatever transparent mode, and the questionable (?) durability. 9.5/10.

I've gone through several pairs of cheap and mid-price ear buds (< $100). Three I like are the earfun pro 3, 1more comfobuds pro, and now the Anker Liberty 4NC. Overall the Ankers win hands down. I think they have the best sound and by far the best wind resistance. After you load up their app and connect to the buds it gives you a hearing test to give a base level of response, then gives a bunch of A-B comparisons to a piece of music asking which one you prefer as it tweaks the response curve. I think the end result is great, but I'm no audiophile and am 65, so take that for what it is worth. The other two are good, too (I rate the 1more buds above the earfun's, but I like them all). I got the 1mores first, and if I were only going by sound quality I'd have stopped there (glad I didn't, but I didn't know that at the time!). I usually listen to them when I ride my bike on a local rails-to-trails path. The downfall of the 1mores is that there is a lot of wind noise that comes through. Noise cancelling overall is good, but not for wind. So I saw the earfuns on sale, so tried them. Much better wind noise reduction, but still more than I'd like. Finally I saw these and bought a pair on their launch. As I mentioned above the sound is great, and the wind noise reduction is very, very good. I hear a little from time to time, but most of the time I feel the wind on my face but can only hear it if I am really looking for it. They have a lot of modes you can set it too, but the one that works the best for me against wind is manual mode, maximum (level 5) noise cancelling with wind reduction on. They remember their settings no problem after you take them out of their case. The earfuns seemed to turn off sometimes (go back to non-cancelling mode). The worst thing about that in the earfun case is that in order to connect to the buds with their app you MUST have an internet connection. This was a problem on my last flight as you might imagine. The 1mores were great on the flight -- and no issues about connecting to the app in flight. It was a transatlantic flight and they ran out of juice so I switched to the earfuns for a while so they could get enough charge back into them. With the 1mores the engine noise and other extraneous airplane sounds were almost gone and I enjoyed my music. I have not flown with the Anker's yet. Hopefully they will do as well as the 1more's there (but I'll have the 1more's along just in case!). Supposedly the battery lasts longer in the Anker's, but only ride for about 3 hours at a time so I have not tested that. One final GREAT thing about the Ankers vs the others I've tried is that you can disable the on-bud controls. I always have my phone on my bike, so if I need to change modes I can do so. Since I found settings I like I don't need to anyway.... In the app you can select what every combination of taps does individually. And every combination has a do nothing setting. You'll still get a beep if you trigger the setting while inserting or wiggling the bud around, but it has no effect. Just what I want. If I want to skip a song my phone is right there, usually with the app up that is playing said songs. Sometimes I start hearing wind, and that just means the buds have slipped a bit. A quick twist or wiggle and the wind is gone. They've never fallen out, but I'm riding a recumbent so I'm just sitting in a lawn chair while I pedal. I use these only for listening to music. My wife called me when I was out while using the earfuns and she said I sounded fine. I have not used these so far to talk on the phone while I ride so I cannot speak to that.

These sound great. Noise cancellation is a big plus, although it does change the sound quality slightly. I use these while cutting the grass and it drowns out the lawnmower noise. They hold their charge and extraordinarily long time. The charging case is nice to keep them safe. For the money, they are well worth it. The app works great and has added features and functions that are great to have. I would HIGHLY recommend these as a very affordable option to other noise cancelling ear buds.

I've had these earbuds for around 5 months now and I think I can give them a pretty solid review. The earbuds have a great battery life, I only need to charge the case around once per week max and that's with hours of daily wear. I've even fallen asleep with them in (more often than not) and when I wake up, they still have a good amount of battery left. Now for those of us who are unfortunate enough to have small ears, these may not be for us. My ears are small, not crazy small but small enough for most earbuds to be too large and cause uncomfortable pressure. These earbuds stay in either really well or I'm having to adjust them constantly. I'm not sure why this is the case but it is. However, the number of times I've fallen asleep in them, I don't typically wake up with them missing. I do feel that these are a bit heavy because they really FEEL like they're there. My ears get fatigued from them after a few hours. In terms of the bluetooth and multipoint connectivity, this is where they lose some stars. At first, they were great and I was thrilled to finally have a pair of earbuds with multipoint, however this was short lived. Sometimes they connect flawlessly, other time not at all. They will take several times to connect to just my phone, or if they do connect to my phone without issue, they have problems connecting to my computer. If you own any bluetooth products by Bose, you'll know that their multipoint connection works pretty seamlessly (in my experience) and your phone audio isn't automatically prioritized over your computer. The same cannot be said for these earbuds. If I have a video actively playing on my computer, and I happen to open an app on my phone, they'll automatically start playing whatever is on my phone. Additionally, I've had issues with the sound cutting out on my computer when I send a text from my phone without any sound on. In general, the multipoint works as it should around 60% of the time. There's also the occasional issue where they will take several tries to connect to my phone which can be very aggravating. My final thoughts are as follows: these are really good for the price! The sound quality is great, they're pretty noise cancelling, and the app makes them customizable. Their shortcomings are not in the functionality as earbuds but in what they're advertising as multipoint connection. If you're like me and have small ears, these may not be the most comfortable for you. But if you only really want them to listen to things on your phone or computer (one at a time) and you have normal sized ears, I think you'd really like these!

When I got these, my expectations weren’t really high. Because I’m used to over the ear style headphones. These have more than exceeded what I have expected! I needed something that does dual device support for my laptop and iPhone/iPad, does clear calls that filter out background noise.. music/podcast sound great with crisp highs and lows. They are comfortable, seamlessly connect, battery last all day. I really like that I can mute calls, meetings, from my watch. They are inexpensive and well worth the costs!! They do everything I need since I WFH and on the go.. 10 out of 10, will recommend!!

These earbuds WOULD be awesome if they worked properly. The noise cancelling is really bad. When it does work, it sounds amazing. But that only lasts a few minutes. Then you start losing bass randomly in each earbud. The sound increases and decreases randomly. I turned off all the touch features, reset them. Nothing worked. I contacted Soundcore support, who is great, and they had me send the buds to them and they shipped me a new pair. These had the problem worse. I went online and saw many posts saying it's a known issue and people are waiting for Soundcore to fix it. Here is a direct quote from their support: "We greatly appreciate your continued patience and support. Regarding the product issue you encountered, we have received the latest confirmation from the technical team and therefore wish to have an open and honest discussion with you. First, we would like to update you on the latest situation: After thorough investigation, our technical team has basically determined that the abnormal sound issue you are having may be related to the hardware and software interaction mechanism under specific usage scenarios (such as the tightness of the earbud insertion, sudden changes in ambient noise, etc.). This is a relatively complex low-level interaction issue, and the team is currently working diligently to resolve it completely through a subsequent firmware update. Therefore, we are suggesting a refund for you, primarily based on two considerations for you: 1. Replacing the order may not fundamentally solve the problem: Since the root cause of the problem points to a specific interaction logic between the product firmware and hardware, even if we replace it with a brand new device, the new device is still highly likely to have similar issues under the same usage scenarios until the fixed firmware is officially released. We do not want you to have the same inconvenience and waiting again. 2. Uncertainty Regarding the Repair Timeline: While our technical team is working tirelessly, fixing, testing, and verifying such underlying issues requires a rigorous timeframe. We cannot currently guarantee a specific firmware release date. Therefore, we believe that offering you a return and refund is the clearest, most responsible, and best way to protect your rights. This is not an attempt to evade the issue—on the contrary, it's precisely because we have thoroughly investigated the complexity of the problem and are unsure how long you will have to wait that we should not burden you with this uncertain risk." So I'm returning them. Great support. Would have been a great product if it actually worked. I thought that just using the Normal setting, but it does it there too. I really liked the idea of these. Very disappointed. UPDATE: I did some more searching and found some reddit posts talking about how the proprietary tips weren't deep enough. Following their advice I bought the SpinFit NEO for IEM in Medium. They were not easy to get on, but got them on the third try. The Result? MAJOR DIFFERENCE! Noise cancelling is way more stable, but still a little buggy. Still much better! They don't move in my ears and make a perfect seal. I have zero issues in normal or transparent mode now. The sound on these buds was always amazing, just inconsistent. These tips took care of that. So on to the buds. They have a lot of great features. The battery life is insane. They charge pretty quick. You need the app to really get the sound out. Once you customize your EQ, you get some serious sound. The touch controls are cool too, but I'm not a touch person so sometimes it gets annoying. Their customer service is too notch too.
