I’ll start with the negatives:

1. They only have LDAC and SBC codecs, not AAC or AptX. For those who don’t know what these are, they are codecs through which songs are transmitted from the phone to the headphones, and depending on the codec, the sound quality is affected. This does not mean they won’t sound good; you just need to check what your music streaming app supports (e.g. Apple Music supports AAC and ALAC) and also enable the LDAC function in the Bluetooth settings. I tested the sound with FLAC files and it was excellent.

2. It would be good if they came with replacement ear pads, since without a discount they cost around 150-200. Personally, I bought dust covers to reduce wear over the long term. The leatherette is nice, but it is not particularly durable over time, in the sun, and in humidity.

3. It does not come with a type-c to 3.5 jack adapter, so that’s one extra expense for those who want a wired connection, since most phone models have removed this port.

4. The ANC (active noise cancelling) is strong but also tiring if it isn’t adjusted. The good thing is that it can be easily adjusted from the app. There are various presets and modes, so play around with them to see what suits you.

Now the reasons why I comfortably give 4 stars:

1. They come with their own case. I don’t need to look for extra storage for them and the case is quite good.

2. The app has EQ with some presets and the ability to create your own preset. However, I would have preferred more customization options. I recommend downloading an extra app from the app store if you want more customization, e.g. Wavelet for those who use Android.

3. The sound is clear and loud. You just need to first enable the necessary settings I mentioned above. Tested on Spotify and Apple Music and I have no issues. The price-to-sound-quality ratio is what won me over (I got them on sale for around 100) compared to Sony.

4. Solid build quality and the drivers fold and rotate.

5. The battery seems good to me, although I prefer charging them every night. Since I got them recently, I can’t speak about long-term performance.

6. They have BUTTONS. Unnecessary emphasis here, but personally I prefer buttons over hand gestures.

7. Nice design as a product and I can’t say they are heavy, although I don’t have a comparison point with other models since I mainly use PC headsets.

In short, they are a legit good choice for those on a budget around 100.

First time buying wireless over-ear headphones, so I’m not comparing them to others in their category, just objectively as a headphone user. Keep in mind I’ve only used them wirelessly.

Firstly, their connectivity is excellent, both on PC (Windows 10) and on mobile. They also charge quickly. The build materials are quality, and they are attractive headphones, with many options for ANC, which even if you don’t use, the headphones seal well on you so noise is greatly reduced (be careful with ANC all the time, studies say it’s not good). There’s also a feature for pairing with two devices, which is convenient for phone and PC with seamless transition.

I find several negatives:

- Firstly, they are the most uncomfortable over-ear headphones I’ve used. Not that they’re terrible, but all the others I happened to have were more comfortable, less tight. Still, if you want them for the gym and do exercises lying down, they often come off.

- Also, it’s unacceptable that they only come with one set of leatherette pads and not a second set of another fabric. The leatherette, as expected, makes you sweat a lot, and I don’t know how durable it will be in a year.

- The battery seems small. With continuous connection to the PC, you get two days and then you have to stop to charge, as you can’t charge and use them at the same time.

- The sound isn’t bad but it’s not what I expected. Especially on PC, you definitely need to use the Fx sound program, which applies some equalizer settings automatically and you get a much better result, because out of the box they just have bad sound (always wirelessly). The problem is that this program has to always run in the background of your PC. And it’s detected as a sound device on the PC, so you don’t actually select the headphones as the device, but this program which is the headphones equalized. The really annoying part is that by default the program always considers a random mic I have connected as the sound device, so every time I connect the headphones, I have to change it. Another thing about the sound, I haven’t managed with the equalizers to make the vocals sound both loud and clear and have balanced sound in the other frequencies. And the bass, although not bad, seems somewhat fake to me.

There are very few reviews in Greek, so I feel that I should cover as many aspects as possible. Initially, along with the headphones, you receive a case for them, of decent quality, a jack cable for wired connection, a USB type C charging cable, and an airplane adapter. As for the sound, there are many aspects to cover. With the appropriate settings through the Edifier app, you can achieve excellent results. Initially, they have very good and clear sound. If you listen to songs with lyrics, you will hear the voices very clearly. I listen to music without lyrics and I am very satisfied. However, the app allows you to adjust the frequencies according to your preferences with noticeable results. Alternatively, you can choose between the classic mode (sound adjusted for calmer music) or dynamic mode (sound adjusted for louder music with a noticeable increase in bass). Personally, I prefer the dynamic mode because the sound in the classic mode seemed somewhat "thin" to me. One concern I had before purchasing them was the volume. I had heard from 2-3 reviews that the volume was quite low (many others did not mention the volume). In reality, the volume is satisfactory. Yes, they are indeed classified as headphones with lower volume, but it does not in any way ruin the listener's experience. If you are someone who wants to listen to music VERY loudly, they may not be suitable for you. As someone who enjoys listening to loud music, I was satisfied. As for the wired connection, the sound quality decreases as the headphones now rely on the device's sound card. A concern for many may be the sound delay (latency), meaning that the sound may not synchronize with a video due to the wireless connection. If you use the headphones wired on your mobile device for social media, you will be fine. There is a slight delay, but it is almost unnoticeable. However, if you play games on your mobile device, you will notice a noticeable delay compared to social media because, as far as I know, games do not recognize the headphones and therefore do not adjust the sound delay for them. In the Edifier app, there is a game mode that reduces the sound delay to 80 milliseconds, but the delay is still noticeable. Other than games, you will not have any issues. There is also a theater mode where the sound is adjusted for watching movies and series, which I never had to use. The noise isolation of the headphones without any additional feature is very good. Of course, active noise cancellation (ANC) provides even better noise isolation (very good in this model), but personally, I did not prefer it because when I paused or lowered the volume, I felt an annoying pressure in my ears similar to the one created on an airplane. However, ANC also provides deeper bass when activated. Due to the pressure it creates, I did not prefer it. However, there is a function that offers the bass like ANC without the annoying pressure in the ears. The ambient mode. In reality, this function is the opposite of ANC, meaning it allows you to hear the sounds around you more easily. Very useful and I preferred it. The sound insulation did not deteriorate at all as, as I mentioned before, the headphones themselves do a very good job in terms of sound insulation as well as in all areas. They are very convenient, of course, after many hours of use, there is some discomfort in the head with any model and it cannot be avoided. Their battery lasts quite a long time. It is stated that they last for 55 hours without any of the functions I mentioned, and 33 hours if you use ANC or ambient mode. Something that is not mentioned is the battery life when using LDAC. LDAC offers better sound quality with much better response and frequency range, but it reduces the battery life more (I believe about 18 hours). But trust me, it is not a problem as the headphones have fast charging capability where you get 7 hours of operation in just 10 minutes! If you are going to use them with a computer, I recommend using them wired to avoid any sound delay. However, if you are only considering getting them for a computer, I do not recommend it as you will not be able to enjoy their capabilities. There are some extra features such as dual device connection that allows you to connect them to 2 devices simultaneously (although LDAC needs to be deactivated) and safe sound where it limits the sound intensity to 85 decibels to ensure ear health. Also, something that is important for me, when I turn the volume to the maximum, there is no sound interrupting the music like in other headphones, very convenient. I hope I covered most people's questions and helped in your final decision. For me, as a mobile and computer user, they get a 5/5.

edit: Actually, regarding the wired connection, as long as you have plugged in the cable, you can open them and they will work with good quality with ANC, ambient mode, etc. without any sound delay. So, they are perfect for use with a computer as well if you don't mind the cable.
