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.

So Raycon advertises heavily on YouTube, which is why I bought a pair a couple of years ago. Maybe other models are better, but I got "The Work," which was comparably priced and reviewed to the others. They weren't bad for ≈$120 buds at first, but they...erm...clogged up easily, with a cheap little screen that I had to remove and clean with this tacky putty from an earbud cleaning kit. After a month or so, the mic stopped working on one, then the other, requiring an annoying delay to deactivate Bluetooth when answering a call, until I finally turned the feature off altogether. Then, after ≈6-8 months, the sweat began to cause corrosion in the contacts on the earbuds, making it difficult to nest in the box for charging, and being jostled in my pocket would make them break connection and connect, unbeknownst to me, so when I switched, it would already be dead. Finally (this was slowly occurring the entire time), the battery life, which started out good (I guess), began to diminish until I'd get an hour out of an earbud, then have to switch. I finally switched. I'd have been willing to pay $200+ for much better quality, but most had enough contrary reviews that I wasn't ready to drop so much. I saw that the Soundcore Anker Liberty 4 NC had consistently excellent reviews, with many comparing them to higher tier products. They were on sale for like $60 from ≈$100 on Amazon, so I gave them a shot. It's been about 6 months now, they fit perfectly, the tips lock on in a unique way that never left one in my ear canal, the screen is fixed and steel, so I can easily push the putty and be done, the mics both work, the app is great, they sound great, and they still last all day. My only complaint is probably that the box's charge only lasts like 2-3 days, but I have one in playing audio all day long at work, and I sleep with one playing (I know you shouldn't, but whatever).

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.
