I bought 2 of these headphones in a row. I purchased the first one, but it was dead and Skroutz replaced it immediately. But even the second one that arrived was also dead!
I chose them because I wanted something very cheap as a backup for the few times I couldn't use my main headphones (e.g. because I didn't have them with me). But in this particular case, it seems that what they say is true, that cheap meat is eaten by dogs (...and cheap headphones belong in the trash can).
