DISCLAIMER: I would like to point out that I previously owned these headphones for about 20 days before deciding to return them because I wanted to get a different pait for travel purposes. Ahhh, Beats:

I've recently considered 2 headphones for travel. Though I don't travel too often (about 6 times a year, 2 being longhaul), I really found good use for bluetooth enabled active noise cancelling headphones
