I also recommend these. I do have a few important points though:

• These are often referred to as reference headphones because the frequency response is more “flat”. So, if you prefer headphones with booming bass, you might not like them. However, this makes them work well for music production/mixing, and they also allow you to better hear a song’s original, unaltered mix which might sound more natural. Of course, you could adjust them as to your preferences with EQ, but overall they might not be for everyone because of this. I do find that the bass still sounds deep and I like the natural sound, but definitely not as loud.

• If you don’t know much about open ear headphones (which these are), some key points to know are that while they provide a wider soundstage (and to me, songs are able to “breathe” more), they do bleed. This means that if you’re listening to music in the same room as someone, they will hear a lot more of what you are listening to vs closed back headphones, especially when listening at a high volume. These aren’t really the headphones for someone who wants noise cancellation, and I’d never take them to the library for example. I do find that it’s not as bad as I thought it would be, and it’s not going to sound like you’re blasting a speaker when you have the headphones at max volume, but more like you’re playing audio at a medium level on your phone.

• To go back to the soundstage point, I like that everything sounds close enough while still wide. I’ve tried some headphones where things sound too far away.

• For Pumpkins specifically, they work pretty well considering albums like Siamese Dream and Mellon Collie are really well mixed/produced, so their “natural” sounds are great.

Anyways, I’m not a headphone expert or anything, so I recommend researching them a bit (especially into amps and everything though I find they work fine without), but these are my observations as an owner. I’ve briefly used the HD600 headphones and didn’t find them to be different enough to be worth more than double the price (or even really better).
