What headphones do you use?

With all these iPod geeks here, I'm curious:
For an iPhone/iTouch, how does the power consumption compare between headhpones and the external speaker? I'd assume the headphones draw less, but for all I know running the program dominates the power consumption.
Does hours of play differ much in each mode?
I've never really noticed a difference, but I rarely listen to the external speaker for long periods of time.
On the subject of digital audio players; One of the best to try to get is the iriver T60 (1.2oz with battery). While the capacity is only 4gb, it was the largest capacity player that took replaceable batteries (AAA). I need to do some testing with mine, but I suspect that a AAA lithium battery would get me about 24 hours of run time on average encoded files.
Sometimes this player comes up on ebay. Great one to keep a search handy for if it does.

From my experience, the headphones drain the least, compared to the built-in speaker and even headphone-jack speakers. Then again, you need to solely isolate the use of the music player, and not think about other apps that take up battery, and even streaming info over 3G/WiFi.
That's what I know about it. I'm not about to do some uber-scientific analysis either.
My Sennheiser Adidas MX 680i are 0.6oz, 17g
Shure SE530.
Tiny, light and being in-ear-canal type, they consume minimal power for big sound.
Sometimes I bring a Sangean DT120 AM/FM radio, or a small mp3 player with radio for weather reports, music, or NPR to keep me company. I don't listen to AM talk because most AM talk show hosts make me want to puke, and I can't afford to get sick on the trail. I use Yuin PK3 earbuds because I find the in ear canal type uncomfortable. Of course I don't use these electronic conveniences when there is a chance of something jumping on my back and biting my neck. Breaking news-"Oblivious hiker with earbuds still in his ears eaten by bear." Most of the time I am content to hear the birds chirping, the grasshoppers buzzing, the frogs croaking, and most importantly, my own thoughts ruminating.
