Summary: I have gone through many open backed headphones from Sennheiser HD 558, 600 & 650, Beyerdynamic Tesla T90 and all open DT seies headphones as well as a few Grados and HiFImans. I was looking for a fun headphone, something that with a full sound but still with a smooth response. There was always something missing by either the music being too flat (no fun) or too much bass or highs that were too harsh and Grados with the overwhelming mid frequency.
Summary: These sound excellent and very accurate. If you want your head to shake from bass beats these aren't for you. IF you want to use them with a computer or iPod, you will need some type of amplification
Pros: Will built, accurate sound, very comfortable.
Cons: Too hard to store. Not portable at all, 1/4" plug. No adapter to 1/8".
Summary: This is my first time buying a high-end audiophile quality headphones so I am basing my review solely on how the SD700 compares to my low to medium quality headphones of the past. I have been listening with the SD700 for about two weeks now and I have nothing but praise for these cans at this point.
Pros: Sounds absolutely awesome to me although I admit I am NOT an audiophile at this point and do not have experience with other high-end headphones to compare it's actual sound quality and reproduction. Build quality also seems very good and leaves me with little doubt they will last a lifetime.
Summary: I have had my HD700 for less than a week but I think I can make some reasonably accurate comments about it after about 25 hours of listening. I should point out that I my comments are influenced by my experience with a well-used Sennheiser HD600 with Cardas cable. I have used the HD700 with a PS Audio and a Musical Fidelity headphone amp. To say that I was underwhelmed with these cans when I first listened would be an understatement.
Pros: A broad, deep and well-defined soundstage. It has a better cable attachment system than the HD600 headphone. They look like they will last a long, long time. They fit on my head securely but I've been wearing them for 4-5 hours at a time without fatigue. They seem equally competent with pop, soundtrack and classical selections.
Summary: I've used most of the old-school brands (Grado, AKG, Sennheiser, Sony, Koss, David Clark, ...) and have tried several of the Jonny-come-latelys, and the HD700s are simply the best for comfort and sound that I know.
I can wear them for hours and never get fatigued.
Most of the others that I've heard fail relative to the HD700 in terms of either wearability or audiophile sound.
I use an after-market cable that's shorter and lighter than the stock cable.
Pros: Comfort, light weight, spectacular sound: response and imaging
This is my 1st 5-Star Review.
I am a very picky reviewer and I am a true believer in 'every little bit counts' and honestly I have little to nothing to complaint about aside from the headphone being a little bit heavy.
The construction of the HD700 is very similar to the HD800. Just by looking at the headphone, you might mistake one from the other.
Pros: Sound, build quality, price-to-performance ratio
Summary: my experience with headphones is very limited, as is this review, but i thought someone might benefit from these observations, someone who wants to listen to classical and jazz.
i started with the hd700 by listening to the melos quartet playing schubert's "death and the maiden," and then checked my impressions by playing segments on my fidelio x1.
wow! the hd700 had what felt like a 220-240o soundstage- i was sitting in the center of the quartet.
Pros: big soundstage, precise imaging, immersive sound, clear lines from individual instruments in, e.g. chamber music or jazz quartets
Summary: After building a very exotic valve headphone amp, with a Sophia Mesh Plate Rec. tube, I wanted to match this thermionic marvel with REAL quality phones. I have a pair of AT ATH700 Airs which I love and think excellent value for $160. I also have my "train" pair of Phiaton 400s with their closed back. The Phiatons are good but the ATs much better. I Googled for the "best headphones" the the answer came back "Sennheiser HD700s".
Pros: Un-coloured sound, feel solid and professional, removeable and replacable cord.
Cons: The cotton cord with a mind of its own, very open design lets a lot of sound out.
