Incredible application in the ear, they connected directly to the phone, sound quality is unbelievable, the battery never runs out, lasts around 19 hours straight when I tried them at 50% volume without noise cancellation. Noise cancellation is among the best, you can't hear anything, and the microphone is also very good; they hear me crystal clear while I'm outside in the center of Thessaloniki with noise from everything around me without hearing what's happening around me. At the €40 I paid for them, they are worth every penny and more

I bought them for everyday use (mainly Spotify).
On the positive side:
Very good sound quality, especially for the price!
They fit perfectly in the ears and never give you the feeling that they will fall out.
The noise cancellation is incredible, as well as the adjustments for medium intensity and wind cancellation. The mode that allows external sounds to come through is quite good too.

Now let's move on to the negatives. Basically, there is just one...
If you are getting them for hands-free use, get something else...
For your conversation partner to hear you, you must be in an ABSOLUTELY quiet environment. In case, for example, you are taking public transport to get around, don’t expect that a call will go through... Every time my phone rings now and I’m with people or on a bus, I take out one earbud and send the call to my phone since no one can hear me.

That's it. I hope I helped!

High-quality construction and very good analog sound across the entire spectrum. The previous ones I had were QCY T13, so compared to those, these are much better. However, the price of Edifier is almost four times higher. I deduct one star for the price.

Good size - too much on the bass but generally good in music, however in phone calls the other person can't hear me at all... I'm sure there are much better options for this money

I got them as good headphones to replace some crystal audio ones that I had for 3 years... but...
Positives:
Connectivity is fast and very easy
The application is easy, simple, and user-friendly
The sound is nice (and I can also hear others well)
Decent noise cancellation
Negatives:
Others can't hear me unless I shout (at least twice as loud as with the old ones)
If the environment is not completely quiet, you just hear complaints all the time that others can't hear me, resulting in me practically rendering them useless since I never speak with them.

I have been using them daily for almost two weeks for phone calls and music. Nothing extreme. I consider the company to have quality products, I had several. I didn't like that the sound and basically the volume of the music when you put them on maximum was not loud, as if it was at 50% of the iPhone's wired ones. Also, in conversation, I had a little issue with the microphone volume (they couldn't hear me clearly), without having a problem with signal and network coverage.

The headphones are incredibly high quality, clear sound, enhanced bass, with support for dsd pcm, mp3.. dizzer, Spotify, calls. In difficult sound conditions like on a ship, construction site with On noice cancelation, they performed excellently! They are worth much more.. Good fit in the ears, they can also be used separately.
The settings through the edifier connect app worked harmoniously.. (and separately)!
The ability to find them if they are lost through the app with a search that triggers an alarm on the headphones is flawless (a bit low in volume)
10/10..!!!

Perfect sound quality for music and conversation. They fit very well in the ear. The application is very useful, it helps you see the battery and change the ANC. The ANC works very well at all stages, even the air function! For the 40 € I got them for, they are definitely worth it!

The bass is amazing as well as the volume. I switched from redmi Buds 3 and I have to say that the difference is huge both in sound quality and in the quality of the earphones. Another positive is that the package includes extra ear tips. I got it at 50€ value for money.

So far they have worked very well. The speaker is clear. The battery lasts long enough and they are comfortable in the ear. For this price of 40 euros, I think it is a very good choice.
