Should I buy headphones?

The Headroom gives a fair amount of information at www.headphone.com as well as selling headphone amps (which I use in combination with tubes). As with speakers, it's a matter of taste. I liked the HD600s but sold them, preferring Grado RS-2s (which have great sound but can be a bit uncomfortable) and AKG 501s (very open sound but less bass than the Sennheisers). -- You can look at frequency response curves for these and other headphones at www.headphone.com/layout.php?topicID=10. Good Luck.

The senns are great. Headphones really don't get much better. See the headroom site as mentioned above.
I use the 580's. Two slightly bad things about them: 1. They project noise to the outside environment too - so you might still disturb others. 2. They are open backed, so outside noise will come to you.

The headroom site actaully has a headphone searcher that lets you input some parameters.

Yes. I use Senn. 600s driven by Sonic Frontiers Line 2 tube pre-amp-- it has Headroom circuitry. The 600s are very comfortable, and with open air construction your ears don't sweat during long listening sessions-- don't want sweaty ears! My listening room is right next to our guest room, and as I often listen to music late at night, when we have guests, headphones are my only option. I still prefer speaker listening, but don't feel deprived when I have to use headphones. Cheers. Craig

I'll cast another vote with the crowd (great to be a follower, no?). I've got the Sennheiser 600's with a Headroom Home amp making them go and I really do like the sound (the processor on the Headroom is switchable, for those times it subtracts from resolution). That said, I usually really do prefer the sound through the speakers, even a low levels. It's only late at night when I really feel the need for volume that I find myself firing up the headphones (or when I am trying to isolate the latest funny sound in the system and need one more point of reference). (Though, I have to admit, when it is late at night and I feel the need for volume, I am often, ah-hem, we'll call it too "distracted," to remember to be considerate to the neighbors...).

I guess a lot depends on what your definition of low volume is, but I definately prefer my Senn HD600s driven by a Headroom Home to listening to my BAT/DNA0.5/Vandy 2ci combo at acceptable late night volume. When I have to work at night, I often come home and listen while my family is sleeping. You can boogy or not, but it won't wake them and I find the sound very pleasant, especially with the processing circuitry which eliminates the "music in the middle of your brain" feeling you sometimes get with phones.
