Color: Velvet Black
Absolutely blown away by the quality and suite of features offered by Anker in these earbuds for this price. These earbuds punch way above their price-range and give competitors up to twice their price a run for their money. I've been a fan of their charging products for many years and own a battery bank and wall charger that are still kicking strong almost eight years later, so I can attest to their track record of quality. Their foray into the audio world with the Soundcore line has been incredibly fruitful and reflects Anker's dedication to quality products at reasonable prices! A fantastic example of a trustworthy Chinese company that is uncompromising and doesn't sell garbage to clueless consumers. Review: To start off I will list the few gripes I have with this product. The case is a little slippery and combined with the slanted design of the lid can make quickly opening the case a little bit finicky. There is a button to press to pop open the lid but it is small enough and also very low on the case so that if I press it with my thumb, my thumb blocks the lid from opening anyways; I have to hold it in my fingertips and awkwardly press the button with my nail, or just open it with both hands. There is also no place to attach a lanyard and the only protective case on the market for it is a crappy third-party silicone one that does not fit well. Please Anker release a protective case for these!! Secondly I am personally not a fan of capacitive-touch controls as I will hit them on accident a lot when adjusting the earbuds or taking them in and out; this can be mostly avoided by pinching on the sides of the stem when grabbing them. I prefer traditional buttons but this is ultimately not a huge issue. Pairing: Supports fast-pairing so these were utterly painless and simple to pair to my S21+ in seconds. I have had no issues with connectivity; I have left my phone on my desk and gone all the way outside to check my mail and experienced no drop in connection, even using the LDAC codec. No issues with one bud unpairing, and they automatically connect when you open the case! App: Anker once again keeping the experience sane and practical with an app that is very easy to navigate and lets you very easily control all the features of these earbuds. No fluff and doesn't try too hard. I have no issues navigating these menus to find the settings I want and the most important ones are already front and center when you open the app. The touch controls are fully customizable with short press, long press, double and triple tap options to assign almost any function to. Sound Quality: Wow! I don't consider myself an audiophile by any means, but I would still put myself somewhere in between audiophile and the average consumer, as I am an avid music listener and have experience with higher-end audio equipment I use at home with my turntable. These earbuds perform exceptionally well across a range of music genres, and have great coverage of bass, mids, and treble. Vocals are clear and full and are not tinny or hollow, bass is not muddy (unless you crank it too high on the EQ) and has satisfying kick, and treble is crisp with good detail. Are there earbuds that sound even better? Yeah, but they cost 2-3x as much and these are ~80-90% as good and will impress almost anyone. THAT BEING SAID: you are not going to get this performance straight out of the box. First, I highly recommend using the "HearID" feature in the app to calibrate the baseline EQ for your hearing, and then applying any presets you like on top of that. Secondly, these support Samsung's LDAC Bluetooth codec BUT it is not enabled by default; you will need to find this setting in the app and turn it on. I noticed a substantial improvement in audio quality and clarity using LDAC. Active Noise-Cancelling: Another impressively good feature Anker was able to cram into these for the price. Similar to the audio quality, these punch well above their class and are 80-90% as good as something like Bose, but for 1/3rd the price. There's various settings for the ANC but 99% of the time I just leave it on the "Adaptive" mode and it works exceptionally well. Even walking by a busy street these will dramatically reduce the sound of passing cars to a very quiet and distant sounding windy noise. In other situations like a cafe, classroom, or public transit, these are completely isolating even when playing music at a very low volume. Transparency mode is very nice and will allow you to hear your surroundings pretty clearly, although it is a bit hollow sounding but this is a common quality compromise for latency. One special setting I find useful is "Wind Noise Reduction" which is extremely effective at reducing the buffeting sound of wind during a windy day or while riding a bike, on top of the regular noise-cancelling. Battery Life: The battery life on these well exceed any practical limitations for uninhibited daily use. Even at max power draw with max noise cancelling on and using the LDAC codec, these will easily last 5 hours of continuous play at medium volume. The case can fully recharge both earbuds about 5 times as it takes ~20% battery to do so. It also does so exceptionally fast; fully charging them in as little as 15-20 minutes. Even with extended daily use I have NEVER found myself needing to return them to the case when I didn't want to; periodically taking them out and placing them in the case for as little as 1-2 minutes every hour or two is enough to basically keep them above 70% charge the entire day. So without charging the case these could last me three even four days of regular use with no issue. Fit: The earbuds come with 4 different sized flange-style tips with a good range of sizes. It is worth noting however that third party tips may not fit on these as the connector is not round and is more of a rounded rectangle shape. These fit decently snug in my ears but sometimes they can wiggle a bit loose if I am moving around a lot so I don't recommend these for the gym. I also have very waxy ears so that does contribute to them being a bit slippery. Build Quality: The upside to the slanted lid design is that the earbuds are extremely easy to remove and return to the case as there is a lot of surface area exposed to grab, and the magnets that hold them are very firm so you can loosely toss them in and they will "snap" securely into place. The lid is also secured with magnets so there is no latch that can break easily, but is still held pretty securely closed and has never opened on accident even when dropped. Overall the build quality feels very premium. The outside of the case has a classy matte finish that doesn't easily pick up prints or smudges, with a simple recessed logo. The button on the case has a bright LED and there are two LED lights behind diffusers inside the case that light up when the case is opened and the buds are inside; this not only looks very stylish but also provides clear feedback for when the buds are properly seated and charging (I haven't had any issues with the buds not making proper contact with the terminals anyways). The earbuds themselves are also solid and very sleek and modern looking.

I am not easy on my technology, especially anything handheld and that can be dropped or lost easily. I seriously cannot believe these buds are still functioning. The color is beautiful, they sit really comfortably in my ears. I will typically have one in my ear all day at work, and when it does start to get uncomfortable after 3-4 hours, I switch to the other ear. Connection is easy and usually works really well. The app is amazing. I never knew I needed an app for my headphones, but being able to customize the tapping actions is so incredibly nice. I’m getting used to the safe sound mode and think I actually really like that it has a setting for leveling out extra loud sounds. This is extra beneficial when listening to YouTube videos that are always at random volumes. One day, my case with headphones fell out of my pocket into my lawn. Stayed there all day and overnight on a very rainy day. Finally found them the next morning, gave it a few days or a week to dry out before trying to use them again. When I did finally put them in, THEY WORKED JUST FINE. I still can’t believe the water resistance and durability here. I’m not sure I can tell much difference between normal mode and noise cancel mode. I can when explicitly testing for it, but otherwise it seems minimal. Though they cancel noise well enough that I can easily ignore any minor background noises. They do fall out of my ears a bit when I run, but for lifting weights at the gym, they stay in pretty well. I think as much as any earbuds can be expected to anyway. I’ve always loved the Anker brand and regularly buy their cables, but I’m very very happy to see that their quality holds true for these buds. Phenomenal brand, great product, easy decision at such a low cost.

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.
