Very good Bluetooth headphones for all uses, music, computer, DJ.. They have very good sound, you can also talk through them, although of course they don't have the best quality in their microphone..

I have had these headphones for 1 year now. At first, everything was great. Nice sound, good isolation, and good connection. After some time, the Bluetooth started acting up. It would glitch and if you had them on loud, it would cause pain. Also, when I turn them off now, the recorded lady who welcomes you with on/off does it at random times. So, many times at night, I hear them turning on and off by themselves. The sound still remains very good. The ear cushions have also been almost destroyed. I don't use the headphones excessively, neither at the gym nor for rough transportation. Nevertheless, the cushions have opened from all sides and the fabric is coming off. I would not recommend someone to choose them because of the above reasons.

Good evening everyone. Firstly, I would like to say that I do not want to refer exactly to how the headphones are because this has been written by many other users. I want to give a different tip for the common problem that almost everyone experiences, where after a while they do not charge or turn on.
1st: You must have the headphones off.
2nd: Press the + button together with the pause/play button simultaneously for at least 10 seconds and then WITHOUT releasing the buttons, connect the charging cable and hold it for another 5 seconds. This way, you will reset the headphones and they should start charging normally again. Generally, I would not recommend these specific headphones as there are many others that are better and at the same price. I hope I helped!

They have very good sound. However, they have an issue that occasionally occurs where you notice that when you open them, they do not work or charge. In this case, you open the ANC button and leave them until the battery runs out, and then they charge and function normally. Other methods are suggested in the comments of Skroutz, by doing a reset. The ANC function is probably basic.

In about one year, the ear cushions of mine started to wear out, although they are still functional.

Definitely one of the best in terms of "Budget" price that I have purchased, 10/10, they truly have "Crystal Audio". As for the mic, 6/10.

A friend through the reviews for the headphones put a correct way to reconnect the headphones with the charging and the reactivation of their blue by resetting by pressing the +- together with the power button for 10 seconds and having the switch set to off. Thank you very much to the guy because I would throw them away

I bought these headphones about three years ago and I was very satisfied, especially with the build quality. One day, one of the headphones stopped working after being poorly transported in a bag. The official representative of Crystal Audio informed me that the company does not provide spare parts and simply urged me to throw them away. Of course, I have no intention of buying products from this company again. It's a shame because these headphones were very good for their price and I had gotten used to them. Unacceptable attitude from Crystal Audio... after all, I wanted to buy spare parts, not have them given to me for free.

After 1 year and something, they stopped charging correctly/sufficiently, but I thought I didn't place the cable correctly. Eventually, they stopped charging completely, so they no longer work via Bluetooth, even though the Noise Cancelling light turns on normally. Additionally, the "pads" that cover the speakers tore apart from both ears, even though when I wasn't using them, I stored them in their case.

The service told me that there are no spare parts, and since the 2-year warranty has passed, nothing can be done.

They are not worth their money. I have wireless headphones of the same brand that have lasted much longer and in harsher use during workouts.

I have them for 10 months now, using them 3-4 days per week, they work very well.
The only negative thing is that the ear cushions have worn out quickly, but they don't bother me.

The fourth pair of headphones they have given me. They literally charge whenever they want.. not one, not two, not three.. four and these have broken again.. tiring to keep returning them

Away from these headphones, they broke within 1 month. They are not even worth 10 euros, the bluetooth doesn't work, the on/off doesn't work, they are garbage

It discharges excessively quickly in Bluetooth mode, specifically within 5 days from its purchase, and I am fully disappointed so far. I basically bought it for Bluetooth functionality

After less than 1 year of use, the material that comes into contact with the ears has worn out and does not charge. Sometimes it can charge, but most of the time it cannot. I don't know if it's the headphones or the charger's fault. The result is that I don't have headphones and I have to buy new ones. If it wasn't for this problem and the wear of the material, I would have been quite satisfied.

I bought the aforementioned headphones on sale for 59 euros, believing they were of good quality. Alas! I have returned them twice and I'm going for a third time. Despite the fact that they should have been replaced, they continue to return them to me, as after one cycle of charging, they stop charging each time. The headphones remain on and off and do not charge until they are completely discharged, as shown in the photos... I hope they will replace them with the third one...

I received them on time, the packaging was very good. The product seemed very good and promising. I charged them and expected a full cycle as stated in the manual.
For a day, I used them for ZOOM, Skype, Calls, and Radio. In the evening, I put them on to charge.
They never turned on again. Neither with On - off nor with a charger, nothing. I returned them and got another pair.
Beautiful construction but a bad product.

Being a owner for already 4 months... the product is disappointing. In the two-month period, I went to the dealership for repair since they wouldn't open or close. They replaced them with new ones (since there is not even a minimal service) with a new warranty. Before the month was even completed... they broke down again. I have to take them back for a new replacement. By far the most wasted 60€ I have ever spent. Disappointing also is Crystal audio... in which I had trust, since I have been buying their products for years... Stay away...

Guys, as good as their features may be, the headphones are NOT worth it. They are defective, see the user comments. I bought them and they broke within a week... Stay away, guys!

I bought them on Black Friday and until today they have stopped working three times. The ACN and jack work fine, but the bluetooth is faulty, the on/off does nothing, and they don't charge. I have to wait until the battery completely drains and then charge them again to get them working. By reading the reviews and comments/questions of others, one can see that the problem is universal and not just with my headphones. They have nice sound, but what good is that if they only work when and if they want to.

It stops working while the ON/OFF switch doesn't work either and you have to wait for the battery to run out in order for it to work again

Brand new, they don't close or open, they don't connect to Bluetooth, they are useless, stay away!
They have bugs when the microphone is activated, the sound gets distorted, you can only hear games in mono and not stereo, which is prohibitive for me. Thankfully, I have the 15 euro headset for 4 years now and it's still going strong.

SOLUTION IF YOUR WIFI+ CHARGING DOESN'T WORK: leave the ANC headphones open until the battery is completely drained and they will disconnect very strangely, but it worked for me.

Update 21/1/21
The headphones work perfectly, I haven't had any problems with charging or wifi. The sound quality is very good and they are very comfortable. The battery life is exactly 20 hours without ANC technology, they are worth it, especially if you use them with cables, that's when you see their true abilities because their lows are even better, especially the mids. Another big positive is that even with full use, your ears don't sweat! Final opinion: 9/10.

Within 4 days, the Bluetooth mode stopped working and they no longer charge. This happened after I tested them on Discord and realized that the headphones don't have a microphone. This is the ANC technology for sound isolation.

Unfortunately, from the next day of purchase, it stopped working. It wouldn't open or close, connect via Bluetooth, or show any indication on the lights. Luckily, it only works with the cable and hasn't become completely useless. Purchased from Public with nonexistent after-sales service.

tl;dr; Stay away. Disappointing microphone. Disappointing ANC.

In the spectrum, the headphones are relatively flat.
Disappointing first impression with the active noise cancellation. Not worth it because it doesn't work properly. I hear more noise when I activate it.

The headphones are definitely worth their money, they have very good build quality with many metal parts, very comfortable in the ears and do not tire at all in use. The sound is of the Monitor type, meaning what the mobile phone - computer gives, you hear without extra bass and the like.
In use for calls, they were very satisfactory, they heard me clearly and loudly. The ANC impressed me and although it didn't play any music, it does a pretty good job, but I don't have enough experience on the subject to say for sure if it's better than others in its category. Purchased on sale from Media Markt for 60 euros. I bought these specifically for use in the office, which are great with the Monitor sound and the ANC easily isolates you to work more focused.
