Automatic setup programs are supposed to be easy, but they can stump home theater neophytes.

First, let's describe what auto setup systems do.
They send test tones to all the speakers and subwoofer, and use a microphone to pick up the sound of the speakers in your room. Auto setup systems determine speaker sizes and volume levels, set the subwoofer-to-satellite crossover frequency, measure distances from each of the speakers to the listener, and confirm that all of the speaker cables are correctly hooked up. Some receivers also use equalization to balance the frequency response of all the speakers.
Auto setup systems go by different names, but they all do approximately the same thing. Denon and Onkyo feature Audyssey; Sony has Digital Cinema Auto Calibration, Pioneer Multi Channel Acoustic Calibration, and Yamaha uses a Parametric Room Acoustic Optimizer.

The exact positioning of the auto calibration microphone is crucial for achieving accurate results. Some auto setup systems work from just one mic position, which would be the primary spot where you sit when watching movies by yourself. Ideally the mic should be placed at the same height as your ears when you're sitting watching a movie.
If you have a camera tripod, use it to place the mic at ear height; perfectionists should move the couch entirely out of the way. Lacking a tripod place the mic on the back of the couch, atop the highest pillow.

The better in-ear headphones also do a great job of sealing out external environmental noise so you can listen at a lower (safer) volume and still hear all of that amazing detail. The problem is, unless both earpieces are sealed tight, you're not going to get the sound you paid for.
Everybody's ears are different, so achieving a perfect fit can be a tricky exercise. Most in-ear headphones come with a selection of differently sized and shaped eartips. Try them all; the goal is to produce a the best possible "seal," which reduces the amount of outside noise you hear and delivers the headphone's fullest-possible bass response.
The difference in sound quality between a good seal and an iffy one isn't subtle. It's definitely worth a little extra effort to maximize each tip's seal. Remember, too, that poor sealing makes for a less secure fit, so the earpiece is more likely to fall out of your ear.
Tip: Your left and right ear canals may not be exactly the same size; you might need, for example, the smallest eartip for your right ear and a medium tip for the left ear.
I've included a gallery of images to help perfect your in-ear insertion techniques. First, try rotating/twisting the tip slightly as you push the headphone inside the canal.
