- they are really comfortable; and
- they are much better quality than the MP3's I'm listening to.
But I found these headphones in the basement on the weekend while digging through boxes (ie "ineffectually moving things between piles") and figured I'd bring them into the office. I have recently gone through a couple phases of music listening, first commandeering an old iPod of Alex's that isn't being used, then deciding I'd just listen to the music through iTunes on the laptop directly. I still have the iPod earbuds for use when I am on the road, but these headphones are great for the office.
I used to listen to music directly off my phone, and I still do sometimes when I am in between calls while wearing the headset, but I've tried to become more battery-use conscious because I've had some days where I've been critically low on battery.
