These sturdy earphones fit gently into your ear to give you the deep tones that only a quality system can provide. I am a traveler that listens to headphones constantly. Not only do I travel by air, I also have a long commute a few times a week. These are great headphones. The sound quality is the best I have heard in an ear bud. Delicate fit and still brings different sized ear covers let you adapt the earphones to fit the size and shape of your ears perfectly, reducing ambient noise so that you can focus more clearly on your music. The earphones also offer you a cord with plenty of length to store your cell phone or any other media player in your pocket or backpack, even in an arm band when you’re at your most active. Only con these do bleed sound, so the folks travelling next to you or the spouse in bed may complain if nobody wants to hear what you are listening to.
