The comfort travel headphones are as the name implies comfortable. The sound quality is good, for my non-musical ears, especially when the noise cancelling is switched on. The noise cancelling is fine for low frequencies, but as with many noise cancelling systems, higher frequencies are more difficult to cut out. Nonetheless, while playing music, there is little distraction other than when stood next to a fog-horn. Of course, these headphones are very much at the budget end and cannot compete with alternatives ten times more expensive. But, for the price, they are very good and do the job well.
