yeah, earbuds are great when on the go. I use my ex81's on my hd5, and they do sound very good. I am not so sure about getting etys, mostly because of all ive heard about build quality issues, and at the price they are, those stories just make me cringe. I could have forked out the extra cash for etys instead of my ath-900's, god knows they would have got more use, on my r909, and hd5, but the world can be very unforgiving out there, and if anything happened to earphones as pricey as ety;s i would be a mess. For home use, im sure the etys are amazing, with no extra outdoor noise, along with their isolating properties, they probably immerse you even more, in quality and detail even more than my ath-900's. The only problem i have with earbuds is that they are not made to last. The quality of the rubber on my ex81's being a prime example, fraying. I should be glad my ex81's have lasted me almost a year, but for the price tag, i was hoping for better materials. I am actually going in the other direction to you, haha, having ordered a pair of ath-fc7's, to accomodate my outdoor needs. Depending on how they sound out in the real world, i will get another pair of ex81's further down the line, and use the fc7's at home with my portables, to prolong the life of my ath-900's. Welcome to the earphone scene chris, I hope you are able to take better care of your ex81's than i was. For their price tag, their sound really is worth the money.
