I believe they are worth it, for their price. The only downside is that when you wear them for a long time, your ears start to hurt.

For everyday use at home, they have been very convenient and work great. If they are moved a little further away from the connected device, there are interruptions (in a space of 50 square meters, for example, there is a problem if they are moved away). They are lightweight, with comfortable ear cushions, and have good sound quality... honest for their price. The only negative thing I have found is that when they are turned off, as soon as they reach 60% battery, they make a very loud and annoying sound in the ears every few seconds until you plug them in.

We only use them with a card. In some pieces, the sound is very low and does not decrease. Other than that, we are very satisfied. This is the 4th time we have purchased the same ones, and we have also bought them as gifts for others.

For the money, it is really super. I have them at the gym and they do their job as they should. I didn't expect it.

Purchased for use by a child. The accompanying instructions are not very detailed, resulting in a lot of struggle until they learn the functions of the buttons and can continue listening from where they left off the previous time, instead of starting from the beginning again. Once this issue was resolved, we are very satisfied.

The headphones are not over-ear, resulting in poor isolation and discomfort in the ears after a long time, at least for me.

Very good and with plenty of additional features (radio, microphone, USB) for an economical choice.

Nice little gadget and affordable, with the radio and memory card you don't need to drain your phone's battery for Bluetooth

Use child, 5 years old. Bought for €24.90 on 25/10/2021.
I am against these products for this age group, but I gave in.
Luckily, it is used without urging at low intensity and not very often.
As a technological product, it is excellent for its category.
The sound is very high quality, volume adjustment +/- is good as it should be, menu management is easy.
Wireless provides absolute freedom of movement.
I did not try the Bluetooth range, I did not try the FM radio.
It does not have its own memory, it requires a micro SD card, an additional cost of +€7.90 for a 32GB U1 A1 (120MB/s), its battery charges with a simple micro USB, slowly but not annoyingly, I did not try fast charging, the battery life is very good.
It does not play certain MP3 files, such as the one from

while it works perfectly with
