Specifications are collected from official manufacturer websites. Please verify the specifications before proceeding with your final purchase. If you notice any problem you can report it here.
The store where I bought them is exemplary. Immediate response and shipping of goods! The headphones, because they are also for calls, have a microphone, but it is not sufficient. The microphone is terrible. The sound quality is mediocre, as well as the construction. You are afraid they will fall apart in your hands. Not recommended!
In the second time I used it, one earphone lost sound.... After a month, only one is working... It disconnects and the sound cuts off...
The service was good, they were replaced immediately with a new warranty receipt!
It is perfect for 9 to 20-year-olds, it puts you in a different world. I have had them for 2-3 years and they are still durable
Nice, perfect in sound and everything, the only problem is that they hurt your ears a lot after hours of use, personally it has caused bruises in my ear.
New and latest update.
Guys, headphones that are only two and a half months old and they have already broken on me.
In a moment, with a gentle movement to put them on, crack, the frame on the left side broke.
I tried using tape, but it doesn't hold and it also affected the right side of the speaker.
I am completely disappointed, I'm crying my money right now.
At first, it was good with satisfactory sound performance during music listening and phone calls, while the battery lasted for a few hours! After about a year of continuous use, the sound reproduction performance started to noticeably decline, the battery discharged quickly and lasted very little (not even 2 hours on standby), while the ear cushions began to deteriorate and dirty my ears with black particles (I had bought them in black color, you see). Final conclusion, a cheap Chinese-made product that initially appears sturdy and of good quality, but quickly you realize it's not worth it (maybe for only 10 to 15 euros you can get a year out of it and then buy something else), and it's not even durable since a single drop is enough to break them!...
Purchase at 16.87€
I usually evaluate after a certain period of time, but here things are clear.
In the positives:
The price of the product is very tempting. I say this because at this price, such sound quality is not easily found!!!
Crystal clear sound, beautiful bass, you enjoy listening to music!!! I played Pink Floyd's song (one of these days), which for me is a benchmark for bass, and I was amazed by the crystal clear sound, the bass, and the transition of sounds from speaker to speaker!!!
They are loud and don't distort at maximum volume.
Relatively lightweight, weighing 180 grams, and foldable for easy transportation.
During phone calls, they work perfectly, I can hear them perfectly without interruptions or strange noises. The tilt control is easily done through the buttons on the headphones.
The packaging includes a micro USB cable for charging and a 1.20cm cable with gold-plated 3.5mm jack ends.
It has a two-year warranty.
Good battery, 300 mAh. It's best to charge it with a low Ampere charger (500 mAh) and not with mobile fast chargers. It lasts for sure 2-3 days, depending on usage. The booklet says 18 hours.
Nice packaging with instructions in Greek.
Let's not forget that Crystal audio is a Greek company, and that's one of the reasons why I chose them!!! Designed in Greece and manufactured in China.
The positives end here... because something went wrong in the process of sending the designs to China!!!
Is it possible for these headphones to fit on a Greek head??? NO!!!
I read the reviews of others saying that they are tight and put pressure on the ears, and I thought... how bad can it be..!!! Unfortunately, it's true!!! The arms of the headphones sit on my ears with great difficulty, resulting in them not covering my ears properly, and when walking or running, I can hear the air whistling inside the headphones.
The pressure on the ears is significant, and after a short period of listening, it becomes uncomfortable.
The folding mechanism of the headphones, as well as the overall extension, does not inspire confidence in solid construction.
For cost-saving reasons, it probably does not include a charger in the packaging.
If someone thinks they have a small head (similar to the mannequins in clothing stores) or wants to give them as a gift to a child, they should buy them.
It's a shame... because I really liked them for their sound quality!!!
I had these headphones for 3 years and once I closed them for transportation and one earphone broke. However, the overall quality is quite good with just a sensitivity issue in folding the headphones, and the sound personally seems quite decent to me. The ear cushions have not suffered anything after daily use, and I particularly appreciate that they are wireless but also have a port for a cable if for some reason you want wired use. After the previous ones broke, I made a new order because I was very satisfied.
They have a very powerful sound. They satisfactorily isolate external noises. They lasted for about 2 years with frequent use. After a long time, they started to break down, but it is reasonable after continuous use. It is also convenient that they fold to fit in various small spaces.
The headband has broken in three consecutive points. You glue one, it breaks below.
The leather of the cushions crumbles after 8 months.
Frequent disconnections.
So far, I keep them because I don't have high expectations. Their time is approaching.
They lasted me for 1 year. Decent enough. I got them for 30€, and for 30€ you can get better headphones now. The sound is okay, the bass could be better, and they distort the sound a bit, but some Philips headphones I bought 8 years ago have better sound than these. And they have lasted me until today. These ones broke in the first year. They don't close/shut tightly, they break with great difficulty, and that's how they broke completely. Also, I have long hair and they would pull my hair on the headband and it would constantly hurt, so that's another design issue. My head is relatively small (relatively, I wear children's headphones and glasses) and they didn't tire me out and were approximately the right size for me. It would have been nice if they were a bit bigger.
I bought them a year ago for the price of €30 and they were the cheapest headphones I had found. Now I see that they have dropped to €15.90. For €15.90, they are amazing headphones, with strong sound and bass, and comfortable even though they make my head hurt a little after some time. For €30, I would expect a slightly better construction, more quality and not so fake plastic. Their battery lasts a long time. At this price now, I would say it's worth buying them. At the price of €30, I believe there are better headphones available
I have them for almost 3 years, playing every day non-stop, excellent quality bass and the JBLs are top-notch.
I was expecting them with so much joy and honestly their sound was very good. The problem is that they wouldn't charge... I had them charging for hours and they stayed at 20%, resulting in only 10 minutes of Bluetooth use... I said it's okay since they have a cable, I won't return them... within a week, the sound completely broke and I didn't use them anywhere else other than my phone... for me, spend money and get JBL or Beats instead
Kids, very good sound but two negatives: Firstly, they open and close very difficultly (terrible mechanism) and secondly, they broke on the first clumsy grip when I took them out abruptly. They lasted about two months, so 2 stars.
I have had them for 2.5 years and they still work as they did initially. Quite satisfactory sound and bass (for their price). The lifespan is a negative aspect because they do not last more than half -1 day of continuous use. The construction, although it is plastic and you can feel it, they have endured all these years. Of course, today they broke (cracked from opening to wear them). For their years and price, they were definitely worth it.
Everything is fine with the headphones in general, but whoever made them must have taken measurements from an 8-year-old's head. I do not recommend them for adults unless they have a small-sized head. For heads with an oval shape, forget about it!
The first headphones I bought were these, then I bought some JBL ones and the difference was huge, so don't waste your money on these. For 10€ more, you can get much better headphones
I have had them for three months now and they still work like the first day. Very good and definitely worth their money. The only negative thing is that after a while, they start to hurt your ears. Although the ear cushions probably soften over time because I have seen different things on this matter. The microphone works perfectly and I have no complaints. I recommend them to you and for 20 €, they are the best
I use them for several hours a day and I am very satisfied. After a while, my ears start to hurt, but it is normal to happen. The fact that they are wireless makes them very practical and the battery lasts quite a long time. For their price, they are amazing.
Very nice with amazing bass and very good sound and build quality, but the microphone is a lie, they don't have a microphone and someone who knows can understand it because on the iron that stays in the headphone jack there are two black lines on top which are buttons and sound, not three for a microphone. And I saw it when I did a sound record, it was recording from my iPad's microphone
A great value for their money. It won't leave you disappointed in terms of battery life. The sound and bass are excellent. Better than I expected. It has a few construction flaws, but they are hardly noticeable. It's a good case...
Children after 1 year of daily use. Flawless for their price, the only issue is the cable, which I expected to be included in the 20 euro price. Okay sound, okay construction, okay price. You know what? I recommend them.
For anyone who wants a decent headset for 20 euros that has Bluetooth and a cable at the same time, it's great. For those of you who commute and need a headset for work, this is for you, kids. Very good value.
I have had them for over a year and I am quite satisfied with the sound and bass, as I am picky about sound quality. The construction is relatively good, the only issue is that on one of my earphones, there seems to be a protruding cable at the bottom of the plastic, and I thought they would become useless, but I was proven wrong. I give them 4 stars only because after a certain amount of time, they start to hurt your head, mainly on the top and then on the sides. I wouldn't say they are too tight, but I agree that they are not suitable for larger heads, as I have given them to my husband at times and they do not fit his head at all. Apart from that, I have no complaints whatsoever, and the battery, although it has decreased somewhat, still lasts easily for 5-6 hours with the sound at about halfway. If I turn it up louder, then it starts to drain much faster.
They are very good headphones and for those looking for cheap and good headphones, they are just what you need!!!
They don't cover the whole ear, so there is simply no sound isolation. Good build quality and the sound is good for its price. They just don't work if you want them for serious work or exercise
I got it for my son, who of course uses it a little, I also use it. The sound is satisfactory and the battery life is good, the only downside is that it doesn't fit well on large heads, however it has good insulation
Bought it new for 25€. I can't understand where the other person found it for 12.
Pros: relatively good sound.
Cons: it would be even better if they fit properly in the ears. They press, they are small, and they don't isolate well, resulting in a loss of sound quality. After a few minutes, the ears hurt from the pressure. It's even worse if someone wears glasses. I wouldn't call it high quality. The Bluetooth is weak. It has gaps at 5 to 6 meters with very few obstacles.
A cheap solution for a short call.
Also, I own the CRIST AUD STUDIO 1, which is miles ahead and worth their money.
The headphones are fake, I tried them and they broke within three days. I left them on the bed from a distance of only 20 centimeters and the earpiece BROKE. They are fake, don't buy them, spend a little more and get JBL. I forgot to mention that I had the Bluetooth in my pocket and the connection was shaky. NOT WORTH IT
I bought them on sale for 12.90. Unfortunately, I received a defective piece - the sound was distorted when connected via Bluetooth, and after 2 days of use, they completely stopped playing sound through Bluetooth. Currently, I have sent them to the service center and I am waiting for a response regarding repair or replacement. However, I will review the other aspects of the headphones based on the time I used them.
Firstly, regarding the sound, which is the most important aspect, when connected through the cable, it played flawlessly. The sound quality was very good, especially considering their size. The bass was very satisfactory and powerful. They didn't reach the volume levels of more expensive headphones, but they definitely fully covered my needs for music and movies that I tested them with. There was no distortion when using them with a wired connection, no matter how high I turned up the volume. Hopefully, after the repair/replacement from the service center, they will have the same sound quality when connected via Bluetooth. They will be the best value for money wireless headphones.
As for the build quality, they generally feel cheap due to the plastic material used for most of their construction. They are also foldable to take up less space during storage/transportation, but when I closed them, I felt like they could break with a little more force, so I was very careful. Additionally, the on/off switch is very stiff, and combined with its small size, it is difficult to turn the headphones on/off with one hand. Personally, I had to take them off every time I wanted to open or close them because the switch was quite inconvenient to use.
In terms of comfort, their ear cushions were quite soft (and relatively good quality), but due to their small size, I couldn't wear them for more than an hour continuously without feeling discomfort (although I don't have the smallest head, of course). However, they are very lightweight, and you don't even feel them on your head as extra weight. Also, since they are on-ear headphones, they can get quite warm on the ears, especially in combination with the current summer season, so you will definitely start sweating within an hour.
Their sound, at moderate to high volume, adequately covers the surrounding noise in an outdoor environment, but in a crowded and noisy place, they don't have the best sound isolation.
Finally, the battery life seemed quite satisfactory. When I took them out of the box, they had 30% battery, and with considerable use for movies and music, it took 2 days before they needed to be charged.
In summary, I give them 4 stars due to the average build quality, average comfort for a medium-sized head and above, and the fact that they stopped working within the first 48 hours. However, they are definitely worth the price of 12.90, and if after the repair, their sound through Bluetooth is comparable to the wired connection, then I will definitely give them 5 stars.
Update 29/03/2021:
In the end, Crystal Audio's official service replaced my headphones with a new pair. It took about 20 days from the moment I contacted them until the package with the new headphones arrived at my house. The new pair was perfect and fully functional, with no issues regarding the sound, whether connected via Bluetooth or wired. Since then, and up until now, the headphones have been working normally without any problems, with careful use and handling. Therefore, the headphones deserve 5 stars considering the price I paid, as I don't believe there is anything more competitive at this price.
