The review pertains to this specific use. They were purchased as headphones for a language laboratory at a foreign language center. Average acoustic experience - expected for the cost. Hard and mediocre feeling construction materials. Unfortunately, the headphones have very poor assembly and fell apart within the first 1-2 days of use and essentially cannot be used further. I have been using headphones in this price category for many years and have truly found "dogs" in the difficult use of the laboratory...these particular ones I would not include among them.

Decent for their price. The cable is really huge and as it is rope-like, it tends to break. We will see how long they will last. The volume adjustment on the cable is useful. At first, it was quite tight on the head and it was bothersome, but after some time, it loosens up a bit. Not too much, but depending on your head, you may find them uncomfortably tight.

The negatives are that I can't have them in my ears for a long time. They become tiring. This 4-meter cable doesn't suit me at all. I have tied it in a bundle to reduce its length.

The rating is given considering their price always! They were bought as a gift for my niece but as a good uncle I had to check them out! They isolate the sound from the environment to a satisfactory degree (don't expect miracles) and have clear sound in all frequencies! They are a bit tight when using them for medium and larger head sizes! I cannot comment on their reliability! Typical plastic build quality at a price that others don't offer even "earbud" type headphones!

After quite a bit of use due to remote learning, I can confidently say that they are worth their money. Very good sound, very good noise isolation, the microphone is amazing, they always told me they could hear me loudly and clearly. The only "negative" for me personally, although it doesn't bother me much, is that the cable is around 4-5 meters long, yes you read that right, it's huge, I have it all coiled up. This may be a positive for someone, of course, but with such a long cable, I expected there to be maybe some loss, but nothing like that happens. They are quite big and will fit most ears, although they are foldable, they are very sturdy and of good quality, I have been using them for about 4 months for both music and they are just like the first day we got them. Bought them for 6€

Good bass, bad sound, they don't fit very well in the ears (maybe they are for smaller ears of course), the sponges are somewhat hard and uncomfortable, it doesn't give you the feeling of very good construction, the cable is detachable but excessively long (intended for listening to music on a mobile phone, so it won't bother much). I didn't try the microphone.
The bass, of course, surprised me, but the sound disappointed me again. I would prefer something more balanced possibly.
To be honest though, for €6 that they cost, I highly doubt if there is something that meets all the above as a whole.
It's okay as a cheap gift for a child.
