Now after 6 months not quite use to revenge the affordable price. The Kabl has come directly from the plug and the copper lines can be seen.
The headphones were always treated very carefully, not wound or strongly bent, used daily and otherwise simply stored in an empty shelf.
The last Sony have only after about 4 years blessed with the same usage profile that time, and this also then only 15, - Euro cost, unfortunately this model is no longer produced.
From me so clearly: No buy recommendation for daily use.
