Excerpt: These were one of the most comfortable headphones one could have. However the cord that connects that headphones was not tight and the headphones would get disconnected frequently. I contacted Logitech customer care and they said it was a manufacturing defect. I contacted Staples if I could get it replace, however they did not have the stock. So I returned it back. Really good headphones for the price. Really comfortable and does not hurt even if you wear glasses.
