I guess it's also safe for me to write about my loaner pair.
A big thank you to Sennheiser for allowing me to borrow and listen to their new headphones. I will be sending them back soon and am indeed sorry to let them go.
I will be writing a more in-depth and lengthy review later on.
I spent quite a few hours listening to them. IMHO they are completely worthy of being called the baby brother to the HD800. They share a very similar sound signature while remaining very different. The HD800 sounds like it has more top end and a smoother top end at that. The HD700 has more of a peak around 6,000 - 7,000 cycles making them sound a bit harsh with certain types of music and is most prominent on cymbal hits and certain "shh" vocal sounds. They are an improvement over the HD6x0's in certain areas but make no argument about it....the HD800 remains the better headphone.
The weight of the headphones is remarkable. Very light and at times, it really does feel like you have nothing on. This is a big plus for those of you who have long listening sessions. Fit might be an issue for some as the headband doesn't adjust very well....at least the one on the loaner paid did not.
The inevitable questions, as can already be seen in this thread, is whether or not they are better than the LCD-3, LCD-2, HE500, T1 and other headphones priced at or near the HD700. You can't really compare the HD700 to the orthodynamics as they are a very different technology. The HD700 will not match the slam and low end of any orthodynamic. The midrange is not as lush or as fast as the orthodynamics. In the end, it will come down to YOUR individual preferences and desires. Are the HD700's the next best thing? No. Are they bad? No. The HD700's are decent headphones with some futuristic styling that provides a sound signature very similar but not equal to the HD800. If you can't afford an HD800 but desire a very similar sound at a slightly more affordable price, then the HD700 should be it for you.
