Should I replace the headphones that came with my MP3 player?
– If you really like good sound, yes.
– Most ear-bud headphones that are supplied with an MP3 player are fairly lacking in fidelity. There are a few reasons for this – the first is economics; most headphones included in such a purchase are very inexpensive, and many suffer from poor quality control.
– The second has to do with physics and acoustics.
