SuperMacro IV Headphone Amp

Portable audio players traditionally have poor quality amplifiers built in. Because you're used to it, you probably don't notice that the louder it gets the worse it sounds. Static gets introduced, instruments blend together, and frequencies get distorted. Ipods are known to have among the worst audio quality in the portable music market. A headphone amplifier takes the burden off of the player and does all of the amplification. It also processes the sound, which I'll get into in a minute.

So who needs a headphone amp? Ideal candidates are people who have high end headphones, or even just big headphones. These phones need more power to drive them, so they tax the player even more than usual. Examples are the Etymotic Research and Shure E5 headphones. Another time when it's essential to have an amp is when you're trying to split the audio between two pairs of headphones, as this doubles the power needed from the player.

Have you ever noticed that wearing headphones for a long time is uncomfortable and makes you feel restless? There's a reason for this. When we hear audio in real life, it's never only coming in through one ear. Even if someone's yelling at you directly from your left, your right ear gets a little bit of that through your bones and skin as well as from reflections of the sound. This is called crossfeed. When you listen to headphones, there are some sounds that only come in from one ear. This fatigues your brain because the sound seems so unnatural and it can't place its location. A good headphone amp will automatically crossfeed a bit of audio from each channel to the other ear, resulting in a much more pleasant and relaxing listening experience. This sounds like a bunch of bull, but the difference is obvious once you have an amp.

Jet Lag

I think it's our third day here. It's hard to tell because I've spent a good amount of that time sleeping. However, I'm now over the jet lag and ready for action again.

Last year when we came to Japan we had no jet lag at all. My jet lag strategy is to try to match my sleeping pattern to the destination's. We got into Japan at 4pm on Tuesday, so I should have been awake for 4-6 hours and have slept for 8 hours.

That's how we did it last year and it was fine.
