the point being, if you want to hear your source better, its better to address the problem with solution like (active) noise-cancellation, or (passive) sound-isolation. [latter is my preferred choice]
simply making your headphones louder, is not really good for your listening health.
i think bose uses NC. if thats not effective for you, try sound isolation products.
further, amplifiers can, but dont necessarily raise the absolutely loudness level of your headphones. it just makes the sound better / less distorted at those louder volumes.
I agree with Deniah. I have QC-25's and when they're active, I usually have to turn the volume down to about half to 60% of the recommended volume on my phone (there is a suggested volume level on the phone). The drone of the plane is completely suppressed. Only the unexpected noises (chatter, babies crying, etc.) aren't completely suppressed, but even those are very quiet.
