So here I have a lot to say.
First of all, I have been using this particular brand for at least 7 years and these are the 3 headphones that I change (durable over time until the final fall).

Secondly, I thought I had ordered those with the plastic cover, but in the end, I received those with the 2 speakers, resulting in the inner part of the earpiece getting damaged after a while.

The sound is quite satisfactory, but not as good as the headphones with the plastic cover (I prefer those). Additionally, they give you the ability to hear what is happening around you.

Finally, if there is an accessory that you can wear on such a headphone to isolate the gaps between the ear and the headphone, they transform into high-quality headphones.
