Query: NEVER BUY THESE!!!

I paid full price for these at Best Buy, and I have already returned one pair to the manufacturer that literally fell to pieces in my hands for no reason. Now my second pair has abruptly stopped working too; the sound cut out for no reason in one ear. They were working fine 24 hours ago when I was wearing them in bed to watch something on my computer. I put them on my desk, put them on last night to wear them out of the house, and all of a sudden Houston, we have a problem.Not only are the headphones themselves awful; the people at the company are awful too. I got into a fight with the guy who was in charge of orchestrating the first replacement because they forced me to pay my own shipping to get the headphones replaced.I simply cannot say enough terrible things about this product and this company. I will never buy Phillips again as long as I live, and I heartily encourage others to do the same.
