Do different styles of headphones drain different amounts of power from an MP3 player? I hate earbuds and i fell in love with the bose Quiet Comfort 2 headphones after demo'ing them for a few hours. I just don't want to drain my blackberry's battery in like an hour because of the headphones.

 
I know a limited amount about head phones. But I would guess with drivers being different sizes and having different back pressures depending on shape an size. And some headphones using different imped. then I would guess yes it could vary. But how much.... that is to anybodys guess

 
I don't think so... unless head phones have different imp's... but I think they're all probably 4 or 8.

But the size of the driver doesn't matter... just the impedance... The player is the one that's actually producing the power, so I'm sure the power draw depending on the head phones is purely based on the impedance of the drivers.

 
Don't really know for sure but my DD ear buds don't drain my Ipod battery any quicker then any of the other headphones I own. But then again I don't own anything like the bose. All I own are the DD ear buds, the Ipod ear buds, and the Sennheiser HD201.

 
they do I get good life with shure but didn't with bose tri what evers. I think the shures are 32 ohm some are 24. the better your ear buds are sealed the loweer the volume you need to use and the less power it drains. Also letting the song play and not searching around helps keep ipods working longer.

I went over this issue a lot because i wanted it to last an 8 hour day while glass beading parts at my old job.

i only have a blackberry..no ipod. its either the bose or the senn's i saw at sears

 
shouldn't, think of the ipod like an amplifier, the headphones are your speakers and you're just plugging them into the outputs of the amplifier
2 things to consider here:

1) the resistance of the headphones

2) the sensitivity of the headphones...may make you turn it up more or not as much.

 
I would think the larger ones w. the "muffs" would be more efficient because you don't have to turn them up as loud to obscure the background noise.

I use some nice sony's for my little Ipod Shuffle and it seems to be working out well.

Well, of course volume is going to change it. But, the question makes us assume he meant at a single volume. It still remains, impedance is the only factor in the battery drain.

I have a questoin that is kinda not related...

Does anyone know if / how I can up the voltage on my iPod? I have a 3rd Gen iPod, and at full volume, I have to turn my HU to 50/62 (which is normally ear-bleeding loud) just to hear it...? And I don't feel like making / buying an amplifier for it. But I will make one if it comes down to that.
