Input:
I originally bought these headphones about 10 months ago. They worked great for about 7 months and then the left side just stopped working. I contacted customer support, emailed them my reciept, and a new pair were sent out no questions asked for free. I have now been using the new ones for about 2 months and again left side went out. Contacted customer support and again new pair sent out free of charge.

I would give this product a 5/5 if the quality was more consistent. I want a reliable proudct but at least the company stands behind their product.
