I purchased this product about 2 months ago directly from Amazon and was absolutely satisfied until a few days ago.
Before ordering, I had already read by faulty plastic or that the headphones tend to wear out after a few months and to break.
This problem unfortunately I have also noted in my headphones.
At the height of the CE logo and the "no waste Logos" cracks to form in the plastic, which probably indicate an excessive rigidity or insufficient flexibility of the plastic.
These are only visible when you put the headphones on voltage.
I tried to capture the image. (They picture gallery)
5 Star Plus for Amazon, for good telephone hotline and problem-redemption.
For those who are interested in high-quality closed-ear headphones (primarily for MP3 player or mobile phone) I would currently most likely recommend the Sennheiser Momentum On-Ear.
Should I bring it to me I will by 2 - 3 months also give my conclusion. (Hopefully then with a better rating)
