Pros Exceptionally detailed and open sound, almost equal to the Grado SR325 and it is a closed back headphone with almost no external sound interference. Extremely comfortable.
Cons Pricey from some dealers but I only paid $168.
Summary For a closed back headphone, the sound is exceptionally detailed and clear, almost equal to the Grado sound. Yet the closed back feature permits very little external noise to get in. They are ultra comfortable. I use several headphones but, overall, the Ultrasone 700 is the most versatile because of its ability to block noise unlike the Grados that I use in low noise environments. Some burn in is required.Over time, I used this headphone less and less. The sound quality, while good for a closed back headphone, ended up being no match for the Grado 325. I also tested the Sennheiser PXC 450, a closed back and noise canceling headphone. The Sennheiser PXC has a superior sound to the Ultrasone and also blocks more noise even with the noise canceling feature off or on. Since, the PXC is even more versatile, almost entirely blocking airline noise for example, it is by far my preferred headphone now. It is every bit the equal of the Grado sound with a significantly more comfortable feel.

Pros Best Sounding Device since the Human Ear
Cons 3 Metre cord and 1/4" plug [Requires an adapter for use 1/8" standard audio out]
Summary Having owned these headphones for 2+ years, I have never not been satisfied. Although the 3 metre cord is a tiny issue when using with a mobile device, that problem is easily solved with velcroing the cord together. Whether it's Bono's voice, Gershwin's Rhapsody in Blue, bagpipes or even Elizabethian [Thanks Sting!], every little detail is audible. About a year ago, the bar that connects each speaker broke [Courtesy of little sister]. I contacted Ultrasone's Tennessee centre [A real person answered on the second ring!] and they repaired my headphones for nothing in 4 days [includes shipping Western NY-TN, TN-Western NY]and asked for only for $10 shipping! These truly are fantastic headphones and I strongly recommend them to anyone with even a slight passion for decent sound!
Pros The Surond Sound seems to realy work . The sound seems more to the sides, back and front more than regular headphones.
Cons Like other large headphones , it can get kind of hot, sweaty and steamy inside the phones but i've noticed this with other large headphones as well.
Summary The base notes are great with these headphones, and the mid range and treble notes are just crystall clear. Best sound of any head phone I've tried. There is a realizism about the music that just is so great. you feel Like you are in the middle of the stage with sounds coming from all around you. the earcups go around the outside of your ears, much more comfortable for long listing sessions than earphone pads that press on your ears and it isolates the sound very well so even someone sitting next to you can't hear the music. I find I play these at lower volume levels than other ear phones and they sound just as lound. I thought these were expensive and after having them a short while I now think now they are a bargain for the wonderful sound you hear. They work great on the home stero entertainment system and also sound just as good on little mp3 players like the creative Zen Stone. So small mp3 players seem to have enough to juice to make these earphones work well. I just can't say enough good about the wonderful sound of these phones and am so attached to them that it makes all other earphones and speakers in my house seem crapy sounding by comparison. I have $1000 speakers on my stero and these phones sound much better to me than they do. Whole ranges of sound I wasn't hearing before are now audible. The detail in the music is more noticable, and the stero speration or natural suround sound seems to really have an effect. These really make mp3's sound like CD's they bring out so much clarity. I bought these after reading the discription from CNET and am completely satisfyed. If i lost them i would buy another pair next week, I'd be lost without them now that i'm completely spoiled by the georgeous sounds they produce.
Pros Tight bass, isolation/noise blockage
Cons nothing yet
Summary Glad my HD280s came apart (after 4 years, tho) cus I wouldn't have these otherwise. It's been over a year and I still LOVE THEM!!
Pros Great, deep bass. Crystal clear.
Cons Long cord, but who really cares.
Summary These are by far the best headphones I have ever purchased. These headphones will blow your mind. Any thing you listen to on these things are completely different than you thought. Buy these now.
