  1. Customer

    I have been interested in this product for a long time, and the product logistics is fast. When I opened it, I found that the quality was very good. After I received it, it was used to listen to music very well. It was comfortable to listen to music, and the appearance was also very beautiful, very perfect.

  2. g***c

    Everything seems to indicate that they are original, well packed

  3. Customer

    Great Bluetooth headphones! Great quality! Great service!

  4. H***r

    A lot more than I expected

  5. A***R

    Very fast shipping, and excellent product

  6. E***n

    Excellent I really liked the fidelity of the spectacular audio

  7. Customer

    They are helmets that I have been wearing for a short time but I think they are very good. They were brilliant protected, and inside comes a bag of cloth to store the cables: one to charge them and another to listen to music from your mobile, although it also has a Bluetooth function. From 1 to 10, I would say that they cancel a sound a 7 (with music on) for the price, which is not excessively expensive, I give them a 7 in general.

  8. B***r

    Recomendo! Ótimo Custo benefício!!

  9. a***l

    the headphones arrived dirty for some reason, even though they were in the package, they work great, a little plastic and fragile, but you can understand for the price.

  10. J***a

    Excellent Product

  11. a***r

    All good

  12. J***e

    Well packed, the seller shipped very well protected, I appreciate that. Seems to me an original product (the box has a hologram at the side), however I own two other Sennheiser headphones, and the quality of the materials are not comparable, it may be a licensed product. The sound is very good and superior to other normal headphones, the features of this product are advanced and compatible with the price. It has good quality but it is not a product of the highest quality expected from Sennheiser. I have no complaints about it because the price was okay. I would recommend these for sightseeing or exercising but not for HiFi listening with expensive equipment, it’s ideal for Smartphones.

  13. f***s

    I loved them, the sound is very good, I have only tried them with my phone but I can say that they listen very well
