Shure E3c Sound Isolating Earphones
These are definitely the earphones God would wear on a long flight. They have very realistic sound and truly isolate noise. They come with a wide range of custom fitting covers, so you'll be able to get the right fit no matter what. They've spoiled me for any other earphones.
I love my Shure earphones so much so when the earpiece broke off I was sad to be without my earphones. I sent them back to Shure thinking that I would have to pay for the repair. When they came back a couple weeks later I was pleasantly surprised to find that not only as the repair free but I they just sent me a brand new pair of earphones! AWESOME.
These earbuds are great. The sound is absolutely unparalleled - I didn't even know what I was missing until I used my Shures. They're sound isolating, too, so you can block everyone out without looking like a huge tard.
These earphones are reported to be the best on the market. They isolate the sound so all you're hearing is you're music, not anything that's happening around you. Shure as a company is also very reliable - if something breaks they will fix it for free and possibly send you a whole new pair. Great earbuds, to say the least!
