I bought these headphones with great expectation, however a week; the plastic part that covers the cable in the headphones broke, the material is very bad and delicate. The bluetooth connection is too unstable and you have to disconnect it so that it recognizes the sound well and does not stutter. I love the sound unfortunately the cable broke after 4 months of use and the right earphone stopped sounding, they are not worth it at all. I hate them, I will never buy Sony headphones again.
