The Klipsch S4i on Amazon are 64.00. ( retail 100.00 ). Most good earbuds will run 50.00 up. For the money these are the best I have found and will let you hear "everything" on my CD. They are noise isolating which helps a lot! Don't drop over 100.00 on any earbuds unless you have money to burn. Get Headphones instead.


200.00 on Amazon ( HD 25-1 ) the same I use as an Audio Engineer. ( retail 300.00 )
When Mastering Audio we use Near Field Studio Monitors w/Sub, 2 headphones and Professional Far Field Speakers as in a Home Stereo or Home Theater. Then we test in a car or truck and iPod or MP3 player. Every audio engineer has to go through this process to get the right Master Mix.
