For over the ear, open-aire, or sealed enclosure supraural, nothing beats Sennheiser's range of headphones. And you don't have to pay a lot of money to get great sound. PX 100s, which are 5-star rated on www.headphone.com are only about $50.

Seriously, Sennheiser is best. Grado is darned close. Check the specs. Check the sound. Check the fit. You can't help but come to the same conclusion.:)

I actually reached the opposite conclusion. I used to be a Sennheiser guy, but as I got more serious/ludicrous about hi-fi gear, I became much more enamnoured of the Grados.

The find that Sennheisers are generally more comfortable, but the Grados sound significantly more like ludicrous $$$ hi-fi: you know, that voice-of-God in your living room sound. And I don't mean loud, I mean the lifelike conveyence of subtlety, the awesome dynamic range, and the pinpoint soundstaging that create liquid smooth beauty.

Grado also makes quality phones in a wide price range starting with the iGrado at $50 on up to the Ref at $700. I use the SR-80s ($100) when serious and the iGrado when on-the-go.

As for in the ear phones:

I like the Ultimate Ears Super.fi 5EB ($150) for my real listening in noisier environments, and the V-Moda Duo ($100) works fine when a mic is convenient for iPhone quickie listening/talking.

As you can probably tell, I find the stock Apple phones unlistenable.
 
I enjoyed the sound quality of the iGrado headphones but found the manufacturing of it to be a bit subpar. After about 6 months, the left earphone gave out completely. I sent it in to be repaired but it happened again after a few months.

I'm contemplating the Sennheisers, but if anyone can tell me how good the Grado SR-60's are, I might consider those. Although I hear the SR-60s have a ludicrously long cord; not good for walking around.
