These will do you double-duty. Not only can you use them with your mp3 player or laptop, but also, most airlines have switched to the same “stereo mini-plug” size for their in-air entertainment and movies sound tracks. So rather than use their cheapies, you can reduce the ambient jet noise (and crying kids, bless their hearts :-) ) by at least 10 dB, while getting better fidelity at the same time.
