I don't quite follow the answer as I cannot understand what traveling would have to do with a BLUETOOTH earbud. Aside from that, these are probably the BEST earbuds I have ever used and the noise cancelling is as good as the higher end earbuds. They are easy to set up and have so many options within the set up. The battery time is so long that I have never had an issue and I simply put them back into the case which also charges them without being plugged into the wall. CUSTOMER SERVICE IS AWESOME as they are nice patient guys in USA answering the phone and really know the product well. I would have no problem giving both the product and ALL the customer reps five stars as I have called them more than three times with questions since I am 69 and not the best tech savvy person.
