At 80 euros, they may have no rivals. From speech to music, they are incredible. ANC is shockingly good for buds. Ambient could perhaps be better, although I have no comparison measure for buds; I feel that these particular ones amplify the noise of the wind a bit more than they should and some loud noises (like the sound of cash being held in cash registers when it closes with the spring and hits plastic with plastic inside the register) pierce your ear. But even when there is some noise from machines, it amplifies that too, and if someone talks to you, you still can't understand what they're saying unless you take the earbuds out.

Warning about the high risk regarding whether they will work properly or if they will be defective. In this model from Edifier, my neobuds pro were replaced 2 times until we found one that wasn't defective. That is, they worked correctly 1 out of 3 times. Also, in the TWS330 NB model, I have 0 out of 3 and I decided to completely abandon this model. Edifier is amazing, and with the earbuds, if you finally get a product in your hands that isn't defective, it personally shows me that the rule is for them to be defective.

So I give 5/5, but if you don't have the patience and time for a few back and forths, then Edifier is not for you.

Edit 03/09/24: The only one that worked correctly broke within a week. Stay away from this company!!!

I'm very sorry to say this, but the headphones are disappointing. In my ears and in my opinion, they are not suitable for any kind of workout. I had high hopes and a lot of enthusiasm because I thought the cost would automatically provide me with something quality, and indeed at first, THEY WERE! Beyond the fantastic active noise cancelling and the good call quality, I now conclude 1.5 years later that they are disappointing, and I say this because one of the two headphones started to "squeak," I don't know how else to describe it. The even sadder part is that I didn't use them enough to enjoy them, only during walks or while walking to the gym (there I used and still use the incredible W820NB from the same company, which have endless battery life and very good sound). I don't know if it's covered by any warranty, but in any case, fortunately, it was a gift and their value was €99. In conclusion, at today's price, I wouldn't recommend them. After 2 months from the review, the left headphone stopped charging while the right one stopped the annoying sound I mentioned earlier and works normally. Whatever, I'm sorry

I bought them about 4 days ago. The headphones are amazing, the active noise cancellation and ambient sound work perfectly, better than the airpods pro gen 2, they just have a little more volume, in bass the airpods don't reach the specific headphones for any reason, extremely good sound and strong and clear bass, very clear sound in the highs but the truth is I would like a little more sound but I believe they are complete especially with the open anc. Now about the battery I won't say much because I haven't tested them so much in the battery part but it seems they have a decent battery and charge quite quickly. Now on the few downsides of the headphones... Due to the design they have, the piece right before the ear-tip is very thick and doesn't fit perfectly in the ear, the problem for me is that the left ear has a small difference resulting in the left earpiece never feeling well-fitted, while the right one is fully complete and doesn't move at all, and I have tried all the ear-tips so precisely don't take it as a bad thing about the headphones just this design may not fit many ears, the airpods pro gen 2 I tried I can say they sit more comfortably in my ear compared to these. I am in a dilemma whether to return them if I can or just sell them a little cheaper. But if I didn't have this issue with how they fit in my ear I wouldn't change them at all.... so be aware of this with the design and how it fits in the ear
-(edit) It is the second pair I get because the first one suddenly the sound went bad in the right earpiece so randomly, just now the 2nd pair had the same issue but in both earpieces and it's much worse, I don't recommend them for any reason you will waste your money, the right thing is to get a proper brand (Sony, Samsung, Apple and some others) and not these Chinese ones

So, here we go!! The packaging is impeccable, as if you bought an expensive watch :) The sound is pretty good, but it doesn't have a high volume, so it's not fully utilized! Many songs are not recorded at -0 db, they have a -1 db difference to avoid clipping on streaming services! In my right ear, it keeps falling out after a while, I tried the other ear tips and it's the same! The problem is the spherical shape that prevents the earphone from going deeper into the ear! I won't buy earphones with a bullet shape before the earphone again! If you want to use ear tips from another brand, they might fit, but they won't fit in the charging case! Come on, Edifier, give a little more depth to the case, it doesn't cost much! Sometimes it disconnects, but very rarely, okay, it happens! The noise cancellation is pretty good, I have it on medium and it's okay! But if something brushes against the earphones, it blows inside your ear! That's bad! They charge very quickly, both the earphones and the case! I don't know why, but one earphone discharges 10% faster, maybe it's the battery? In the end, they are decent earphones with good sound for music and calls, but not perfect! That's all :) The phone I'm using is a Sony XZ-2 and XZ-3! And don't forget... be careful not to drop any earphone because you might search for half an hour and not be able to find it! I dropped it in an open space and I panicked, I couldn't find it, I thought it couldn't have gone more than 4 meters away because of its spherical shape, it rolls like balls, hahaha, and it's dark! It requires a thorough search! Update: Many people say that the right or left earphone doesn't sound good, and I had an issue that they played very low! You should remove the small filter at the input with a pin, it's very small, and leave the earphones with the metal filter! These filters muffle and cut the sound! They don't get cleaned if the filter is on top, the dirt stays behind! Now you'll see how clean and powerful they play! Just take a dry cotton swab every week and clean them, and everything will be perfect :)

--UPDATE AFTER CHANGING DEVICE--
While the application is still poorly designed compared to others, after changing mobile devices (from Xiaomi mi 10t pro to Google pixel 7 pro), the connection with the headphones is now much easier and faster. Additionally, it no longer requires an open location for the initial connection as mentioned below. It seems that the intermittent disconnections I observed with the previous phone have disappeared. I don't know if this is a general issue with Xiaomi or this specific model, but the experience with Pixel is completely different.

On the positive side,
the sound quality is amazing, as well as the proper noise cancellation. They fit very well in my ear and don't fall out. The microphone is quite good, and my conversation partner doesn't seem to have any issues with clarity. The packaging they come in is flawless, and the extra membranes that attach to the headphones to support different ear sizes are a nice addition.

On the negative side, the extremely poorly designed application they have to connect to the mobile device definitely stands out. It even requires an open location to detect them for some reason. This is done so you can change modes (ambient sound, normal, low noise cancellation, and max) and check the battery level of each earbud. Otherwise, they can be connected via Bluetooth without even opening the application (but you can't adjust the mode). Coming from Samsung's buds+, I definitely miss the single tap and long tap features (in these, you can only do double and triple taps, but each earbud can be individually customized with its own functions). Additionally, the battery life is somewhat short (they last around 3.5 to 4 hours, even less with noise cancellation), but they charge quickly in the case.

Overall, the negatives are completely overshadowed by the positives, mainly because they are related to the app and not so much the headphones themselves.

Update 24/1/2023

Unfortunately, we are down to 2 stars, even though they still remain top-notch in terms of sound quality. 5 stars for sound.

----------------------------------------------------------------------------

I know that some of you will be disappointed, but this is my final conclusion. The reason why I am now giving them only 2 stars after 7 months is that using them with a Garmin watch (and maybe with smartwatches in general) for sports activities has literally drained their battery. Connection issues (delay, sometimes connecting to only one of the two earbuds, requiring a pairing process from the beginning, etc.), as well as the short battery life even at 80% volume, lead me to the conclusion that they are not worth their price and that Edifier ultimately did not pay enough attention to sports usage and connection with smartwatches. They work perfectly with the phone, which is what surprised me.

Also, a week ago, I returned the second pair because the right earbud stopped working. I do not recommend them for sports, despite having IP56 certification.

--------------------------------------------------------------------------------

Initial assessment - June 2022

As a previous owner of many brands (Aftershokz, JBL, Creative, Optoma, etc.), I have to say that I was amazed by the sound quality. However, this means less battery life because the audio transmission data (bitrate, kHz, etc.) and processing from the device to the earbuds are significantly higher. Nevertheless, the company has a mobile application that allows you to change the quality (they sound great even in the lowest setting), and there you get the bonus of battery life with several options.

Ideal for running and exercise, premium construction. They also have an option to give you a sense of the surrounding sound despite being closed-back earbuds. Essentially, they use the external microphone to transmit the outside sound to the earbuds, simulating what bone-conduction headphones do.

4 stars for one very IMPORTANT reason. If you take the earbuds with you without the case for any reason and you haven't connected them to the desired device, they will shut down and become useless because they don't have an on/off switch like many other similar products. It's a shame...

Owner for about a month.

Purely, their biggest advantage is the sound, incredible across the spectrum. The package includes 7 sizes for the ear tips, the larger you choose, the more isolated the bass becomes in your ear and the treble becomes slightly more closed, the opposite if you go in the other direction, so you try and find the best balance of fit and sound. In any case, the bass is excellent anyway, the best I have encountered in Bluetooth earbuds that I have tried from time to time.

The noise cancellation does a very good job, the more general and lower frequency the sound is (e.g. traffic noise), the more it isolates it (e.g. if a single motorbike with a modified exhaust passes through the general traffic noise, it will be heard).

I haven't made many calls, but the few I made while inside the house, people could hear me clearly, just a bit distant. Now, I don't have an opinion on calls while on the street.

The battery is not something exceptional compared to, for example, the Creative Outlier V3, but in general, it lasts around 4-5 hours. However, with full noise cancellation, it can drop to 2.5-3 hours. The good thing is that they charge very quickly.

Their mobile app has many settings for connectivity and shows the battery percentage of each earbud (as well as the case when the earbuds are placed in it). You can also customize the touch controls, which generally work better than other earbuds but will never have the immediacy of a hardware button.

For those who decide to give them as a gift, their packaging is incredibly premium and impressive, as if it was made specifically for unboxing.

I will finish with the only truly negative thing I found, which I recognize is something subjective and circumstantial. While the earbuds fit well in the ear and do not fall out, for some reason, I constantly feel a slight pressure that I don't feel with other earbuds I have tried from time to time (e.g. I can wear the Creative Outliers all day). I believe it is because their main body is relatively bulky and slightly more angular in some areas compared to others, and the tip of the earbuds that goes on top of the ear tip is larger in diameter than usual, resulting in the ear tip being slightly harder. The result is that I feel fatigue after a while, and I don't know if it will improve over time. I REPEAT, it is purely subjective, they may fit perfectly in other ears.

Overall, these are earbuds that are aimed at someone who primarily wants quality music sound. If you mainly listen to podcasts and YouTube, there are cheaper options with better battery life.

I reserve judgment on their durability and reliability, if something goes wrong, I will update the review.

In the positives, if someone wants to have a pair of earbuds exclusively for sound, it is the ideal choice. I have it connected to a Samsung S20+ with LDAC Bluetooth Codec and we are talking about exceptional performance. Unbelievable ANC, you don't hear any interference.
Excellent for sports as well, as they fit perfectly and don't come off at all.
For music, they are highly recommended.
And I have no complaints about the battery either. They definitely need to be put in the case once a day (with "heavy" use), but OK, they charge very quickly.
As for the eye-candy, they come in an amazing packaging.

Now, in the negatives... Conversations on platforms like Teams are somewhat problematic. They tell me that I sound with interruptions or "robotic", so for business use, I wouldn't say it's the best. It could also be the receiver on the laptop, of course... In conversation through mobile network, I think it's fine. I can hear and be heard very clearly.
The connectivity sometimes presents some issues, specifically there are several cases where you only hear sound from the left bud. You have to put them back in the case, make sure that both the right and left bud are properly "connected," and similarly, when you take them out, the LED on the case should "show" that both have been taken out (a red LED flashes when you take them out of the case). So, this is a bit annoying.

In conclusion, since I listen to a lot of music throughout the day, I consider that I made a good choice. If you want it for your work, you might have to look elsewhere.

EDIT: It turned out that the receiver on the laptop is indeed the issue. My conversations on Teams and similar platforms through my mobile are perfectly fine.

As a predecessor of the Edifier Nb2 (and as a musician), I have to say that the sound quality is close to perfection for this price. The High Noise Cancelation function is significantly enhanced, and overall there is greater ease in adjusting the settings through the Edifier app.

The negatives are as follows:
-Smaller than the Nb2/Nb2 pro, so they may not fit perfectly for some people.
-Smaller size also means a smaller battery compared to the previous models. They last approximately 4-5 hours with Noise Cancelation (at maximum volume) and a few more hours with Ambient mode. The case (with the Tron LED) can charge them 2-3 times.
-The microphone could be better, but it gets the job done (compared to the previous models which were much worse).
-The in-ear detection feature is not available, but it didn't work properly anyway.

Some tips:
-For a louder sound, don't use the equalizer and keep the Classic EQ on.
-Lhdc is supported by only a few Xiaomi phones.
-Ldac (with the new update) is available on several phones, but you will be prompted to download it when you enter the app. It makes a difference in audio quality
