Shure E4c headphones
There are a lot of quality sound isolating headphones on the market, but something tells us you probably won't want to be laying down the family fortune in order to get a pair. Thankfully we have Shure's E4c line to keep us jacked in. Not only do both they feature a complete ear fit-kit (including foam add-ins and small, medium, and large plugs), but these high end isolators have a two year warranty — so even though they'll set you back a good $300, they'll probably be around a lot longer than most of the devices they'll get used on. And if you're looking to go a little lower on the price scale, we certainly don't know any gadget fans who'd snuff at last year's model, the now-$180 E3c line.





















I have the E3c's and got them for only 100 at best buy---kinda odd that they're listed as 180 here.
You probably got the E2c at Best Buy for $100... I saw them at Best Buy also. The E3c are $179 and only sold at some best buy's.
Let's not forget Etymotic ER4 series too. ER4P is great for portable use and although it has less base it is superior in high frequency range - it is truly clear and beautiful. Use 4P-to-4S adapter and it turns into ER4S, which has greater balance and impedance.
Don't forget, you can get these (and the black version) from earhponesolutions.com for under $200 shipped. That's where I got mine.
