I would love to write comments about how much I like this product, but all I received was a sealed, EMPTY, padded white envelope. Anything will work really. I just reordered them in the 7M. Loved the length! BEFORE turning on the speakers! Not only does it have great sound, but it is extremely uncomplicated. EDIT2: Im sitting here at two in the morning listening to these headphones, and I just realized that theres a slight static noise when audio is playing. In my opinion, the sound is better than the Apple ear buds. I wear this to work in an office. Not only are they aesthetically pleasing to him, but he also finds the fit extremely comfortable over his head and doesn?t press against his ears.
