I bought the headphones 1.5 years ago.
Initially, I didn't like the fit, as they are bulkier than the classic ones, but over time I got used to them.
The sound is very good and in terms of durability, they worked perfectly for the first year.
Specifically, after 1 year of daily use, one of the headphones broke and after 1.5 years from the purchase, the microphone also broke.
I had bought them for about 23 euros, which I consider to be a normal price considering their durability. Unfortunately, today their price has increased by 50%.

The first experience is very positive. I chose them mainly because of the brand and the good reviews, and it seems that they are worth their money (purchased for €19.7). Very good sound quality. I was impressed by their construction material. The cable doesn't tangle easily and the headphones fit comfortably in my ear (subjective, obviously). Their material is anti-sweat and they can be worn comfortably and upside down (with the cable behind the ear, if you are looking for something for sports). As for their durability over time, I reserve judgment for now.

From the sound when I listen to music, I wouldn't say it's very good, but for conversation and comfort when I wear them, they are very good.
With the initial medium-sized ear cushion they had, they didn't suit me and I changed it to the small one which is very comfortable and doesn't fall off

Very good for sports activities, sweat resistant, they don't slip in the ear, if you fit them well the sound is very good with great bass, if you wear them more loosely you lose in intensity and quality, but you can also hear the cars next to you, if you exercise outside, they could be a bit cheaper...... and they work perfectly with the type c to jack adapter

I have bought countless pairs of headphones, both in-ear and over-ear, etc. I have had these since January. Firstly, they all have very good sound, bass, treble, midrange, overall balanced for my taste, but of course they need to be positioned well in the ears otherwise the bass doesn't sound good and they don't isolate the environment.
They stay in the ears securely.
The microphone is okay.
Disadvantages are the comfort after some hours of use, my ears start to hurt, and also the cable gets tangled quite often.
I would definitely buy them again.

The worst thing I have ever bought in headphones.

SOUND: Average to poor for their price. Bass 7/10. Mids and highs 4/10.

COMFORT: 1/10. The buds have an oval shape, not round, which means they don't fit inside the ear but rest on it, and the outer casing puts pressure on the ear to prevent them from falling out. It's frustrating to find the right position to put them in the ear, and even when you do, they don't stay securely, meaning they are not suitable for running at all. The worst part is that after a while, the ear starts to hurt, and you can't wear them anymore. I have never experienced anything like this with other headphones. Unacceptable.

I should have returned them. At least I learned not to trust reviews from Scrutz when it comes to headphones. It's the second time I've made this mistake.

Really excellent headphones for their price. Impressive noise isolation, very good in terms of volume and sound quality both in music playback and conversations, perfect and comfortable fit in the ear. Slightly lacking in bass, but that wasn't a problem for me. If they also had a flat cable, they would be flawless. I highly recommend them anyway

Very good headphones with durability over time, they are the only headphones I have bought and they lasted for a year and still continue, with daily use, only a little bass distortion after extended use which is understandable, I would buy them again without a second thought.

The sound is average compared to other headphones at this price... when I talk on the phone or send an audio to someone else, it sounds like I am next to a television and there is interference from my side... terrible microphone (it might have been a manufacturing mistake in the specific one I bought)

The sound they produce is high-quality and powerful. The bass is one of the most important assets. These are the second ones I buy after 4 years of almost daily use. The only drawback I find is that due to the cable, they tend to pull during use and reduce the fit, so you have to adjust them.

I got them as a gift for my husband and he is very satisfied. He doesn't wear them for sports, but he uses them for many hours a day. Compared to other similar hands-free devices, they are by far the best. They are very comfortable and have proven to be very durable

I have had them for about 5 months. The bass and treble are very good and overall the sound is very good without distortions. They fit exceptionally well when inserted upside down, but in this case the microphone goes below the ear and you need to speak louder to be heard. I use them for many hours a day for remote communication and they are reliable. However, with prolonged use (over 5-6 hours a day), they may cause slight discomfort in the ear.

Very good headphones, with good sound performance, they don't tangle, fit very well in the ear, and isolate external sounds very well.

I have had them for almost 3 months and they are worth their money for their sound. If you have a "brick" mobile phone, they are not suitable for running. They are good for gaming.

The headphones have lasted this long and the sound is still impeccable!!! Value for money headphones!! Buy without fear!!

Very good sound, as long as you apply them to your ears. I even mix with them. They are definitely not suitable for running. The claims that the headphones are supported by the cable around the ear are false. Not even for a second. It's just a simple cable. Wearing them upside down, like regular headphones, they are supported quite well. But only for walking.

It's nothing special in terms of both sound clarity and bass. Especially in the bass, they produce a dull deep sound. Of course, you get what you pay for. I don't know if there are better ones for 20 euros. However, coming from the SONY MDR-EX650AP, I was disappointed. They don't come close to the sound of Sony, which also has some issues. So one can understand what's happening with these JBLs. Now, for someone who just wants them to listen to music, having something in their ears that doesn't "kill the sound" and without even having any small expectations from them, they are fine.

Very good construction, they are comfortable and you can't feel anything while running. But their sound when I listen to music is poor, compared to the Panasonic ones I had. For a long time, I thought it was my phone settings, like I had set the equalizer to the default "fake cardboard sound". Such a shame.

Extremely resistant to water and overall, the sound they produce for their price is absolutely satisfactory. A big plus is how comfortably they sit in the ear, which is the best thing for long hours of use because you forget you're wearing them!

For music, it is a decent product, but if you want it for conversation, I would say it is not the best. It does not isolate the sounds from the environment, resulting in voices from behind and external noises being heard very loudly!

I got them for 30€. Very good sound, they fit in my ears incredibly well, they are very durable (this is important) and overall I am very satisfied.

They have very good sound quality, they have a magnet that helps them not to tangle and fit well in the ear :)

Extremely comfortable with a minimum experience of at least 20 headphones up to 50 euros without expressing an opinion on reliability since I have had them for a short time, I recommend them as the most balanced purchase

They are not suitable for running. There is no chance for any headphone without a hook to fit well in the ear. Otherwise, they are very comfortable in the ears.
Update: After 7 months and several thousand runs, I can say that they fit quite well. Without meaning that you can't adjust them on your ears every 5 minutes.
Also, they have been washed many times in the washing machine as I forget them inside my running shorts and they haven't suffered any damage at all.
