As everyone writes. Battery for weeks. Sound: basically, everyone should activate the extra power on android, with applications like volume booster (+10-15% is enough). Excellent frequency response range. Bass exactly as I think it should be. Whether you listen to Pavarotti or Cardi B. NOISE REDUCTION: I want to hear more accurate brands, to see where the edifier falls behind. Simply serious isolation.

If you are looking for affordable value for money headphones, then it is a very honest choice. Good build quality, clear sound, and quite lightweight. For me, they are worth their money and more. P.S. The battery NEVER runs out!

Let's start with the basics.
Sound: It ranges from 27Hz to 15950Hz *Bluetooth*. The sound is very clear with good bass, but not bass that covers everything. If you are someone who listens to music that is purely bass-based, then don't choose it. It is quite tight (recovers quickly, providing very clear mids). If you are someone who likes to distinguish each instrument and clear voices without everything becoming a "boom-boom" in the music, it is a very honest choice at 115 euros for wireless headphones.

2. Battery: Honestly, I don't know what battery it uses, but someone has done their job correctly. I have them and they have been playing for 14 hours now, and they are at 70%.

3. Comfort: In my case (big head), after 4 hours of use, you feel them a little bit more, admittedly they are not the lightest headphones, but the ear cup is quite comfortable and large.

4. Overall, I give it 5 stars for what it offers at this price, and yes, I could recommend it to any audiophile as a value-for-money entry-level wireless headphone.

Edit 21/03/2021... The battery refuses to drop... it's at 50% with daily use

Coming from gaming headsets, this particular model has a much superior sound, especially when using the 3.5mm jack.

EDIT: After a year of use, the cushions have proven to be of low quality. The right one has deteriorated significantly, and the left one has been cut, exposing the inner sponge. For their price, they should have better build quality

The confirmation that when you pay, you get!!!.... the headphones are perfect for their price... the sound is loud and of good quality. Their battery seems to be a monster from the few days I've had them. They are also very comfortable and after using them continuously for 3 hours, they bothered me very little. Finally, they connect quickly to the laptop or mp3!... One negative thing, if I can say, but it doesn't bother me at all, is that when I connect them to the mp3 and turn on the noise cancellation, the songs sound somewhat interrupted... only when the ANC is on...

Very high-quality headphones, I bought them because I travel a lot in the city listening to music and I wanted to try how they are with Active Noise Cancelling headphones... The prices for most of this kind are prohibitive but the Edifier ones are affordable. The sound is exceptional, but as soon as you activate the ANC, the surrounding noise almost disappears. It's an incredible experience and I recommend those who travel in the city listening to music to try them!
