They come in packaging with different sizes for the ear pads for better fit in the ears. Personally, I am fine with the defaults. Quality construction of the headphones while the cable is an average headphone cable that wears out or not depending on the use. Regarding sound, it has been tested on a computer, laptop, and mobile, guitar amplifier, and via adapter on a turntable. The sound is very clear on all the audio sources I mentioned, and I would say that the mid-high frequencies are emphasized more, but overall it has a fairly uniform frequency response, while it is not that loud. If you use them on your computer, you can change the sound through equalizers to bring it to your own preferences. A very good choice for quality sound with a relatively small budget (20-30€).

For all those users that are not aware about IEM (In ear monitors).Buy a DAC(Digital to Audio Converter).You can buy a decent-ok one for just 15-25 euros. It's the one that we are using for 3.5mm if we don't have the port on our smartphones. USB-C to 3.5mm jack. This is basic knowledge in order to have at least some decent performance of them. After that,subscribe to itunes and turn on the Hi-res for a truly great experience.
Thank me later.

Lightweight construction, durable cable, rich sound and sufficient dB. Very good purchase, but I have to tell you a secret. If you connect them to a smartphone, there is a "cutter" in the volume. I put them in a Xiaomi Redmi Note 10S and the sound preferences are reset with every song change, while at maximum volume the sound is very low!!! However, when I connected them to a Yamaha amplifier and an old MP3 player, their volume was satisfactory and they perform at their best. I mention this because some form a wrong opinion when connecting to a smartphone that they have poor sound, but you should know that many smartphones have a sound limiter.

Today I received them. The first impression is that they fit well in the ear, but their sound is "weak", even though it sounds clear and with good resolution. I was swayed by the good reviews, but what I hear is not what I expected, especially when comparing them to the SOUND MAGIC ones that I had and consider to be among the best in this category, with strong, clear, and "full" sound.

Just put on the appropriate cover that fits your ears and their sound is very impressive. I have been using them for about a year now, three hours a day, and they have not disappointed me.

Simply wonderful. Balanced across the entire frequency range. None of the ear tips worked for me, thankfully I had some old ones that fit, but I won't cut off such an incredible value for money product!

I have had them for 3 months and so far they haven't had any issues. Very good sound and a comfortable fit in the ear even after hours. Their body, although plastic, seems to be of good quality for the price range, as well as the tips. The cable could be thicker or better wrapped, and it also tends to pick up some microphone noise, which is normal for this price range, but at least it ends in a G. Overall, very good value for money, but they come without a case and without a microphone with audio controls. For someone who cares about these features and has a little more money to spend, I would recommend the soundmagic e10c

By far the best headphones I have ever bought, with very high-quality sound and extremely comfortable and durable. However, they could be a little cheaper (not that they are not worth their money, but to be more affordable)

If you want headphones for music, they have very good sound.
Quality at a low price and so far quite durable.
I highly recommend them!

They are very good for their price. Although entry-level proposals from expensive companies often do not deserve the €1000, they are an exception. Initially, they are well-made, the cable tangles to an acceptable degree and less than other headphones, and they are very lightweight, which means they are recommended for running. The small 6.5mm drivers do not need to scare you. The volume levels are at least excellent, the bass is rich, the mids are quite good, and the sound overall is neutral. They definitely lose in quality in strong tremble and high-pitched frequencies, but it's something you expect. Also, the isolation from external noise is almost absent.
