While wireless headphones are nice for a gym workout or a run around the block, without a dedicated connector, you can't charge your phone and listen to music with wired headphones at the same time. I have found that wireless headphones don't usually last through the many hours needed when traveling long distance ie. Intercontinental flights. A few hours of waiting at an airport prior to flight, plus add to that 7+ hours in-flight will not last most wireless headphones out there. You'll be without music way before you get there. This would not be a problem with a wired headset since you can charge phone in plane as you listen to music endlessly. Those of us who travel frequently know this rather well. Also, having to constantly recharge your wireless set can be a pain. I have run out of charge in the middle of a nice workout, something which would never happen with a wired headset.
