Please list your earbuds and also music player device.
My choice is the OEM headset for my Blackberry 8310 mated to my iPhone 4s 64gb. The sound is amazingly good for classical music. If you don't believe it, give it a try.
I must be one of the few lucky guys who found a perfect earbuds, or I am having physical disability in identifying good sound. LOL. Man I am having these earbuds running all day long everyday and don't seem having them enough. Can you imagine having headphones or in-ear monitors for that long period?
