Best Travel Buddy Headphones

I've had my mm 550-X's for a few weeks now and they've already been on 2 trips with me. These really are the best travel headphones I've ever owned. Beautiful sound quality, well made, and the best part is they pack up perfectly into my carry on. Thanks for the fast shipping Audio Geeks!

Great sound quality

Noise cancelling function is the only thing that not that outstanding. Sound quality is great with bluetooth connection, and it's even better when you use wire to connect. The only thing that I do not feel satisfied is noise cancellation. It is not as effective as Bose QC15, but not a problem to me since I do not use this function often. Overall, great headphones.
