Scosche Noise Isolation Stereo Headphones with Tapline II Music Control and Microphone for Apple iPod / iPhone
I am not a very discerning listener.  I really can't tell you about bass, treble, etc.  What happened was I lost the headphones for my Shuffle and wanted a replacement pair for a reasonable price (not the $5.00 cheapies I bought that were static filled).  These earphones work well.  My Three Tenors and Peter Paul and Mary albums have great sound - as if I were at home with my CD's.  Good sound and good quality.
