These have been good for me. My wife is often annoyed by the sound of TV or music that I enjoy. The HD650 was for me to make sure that she was insulated from what I usually listen to. The headphones are now on their way to Sennheiser in Old Lyme CT for repair.

I have had these headphones for about 4 months now and can safely say they are the best headphones I've ever owned. I will start by saying these headphones are NOT meant for use with an iPod or other MP3 players. An iPod only has enough power to properly power small headphones.

Fantastic sounding; comfortable

Large; not very portable

The sound is amazing and the comfort is superb. I was not expecting that they were designed to allow the listener to hear through the earphones to what is going on around them. This is perfect for me and means I can wear them for extended periods of time and not constantly be pulling on them to hear...

i thought i had to write a review on these headphones , just in case anyone is in 2 minds to purchas

stunning sound; comfortable fit even after wearing for a long time,superb build quality

none i can think of

Great sounding headphones!. As we know HP are subjective to ones listening taste. Wanted a pair that were not too clinical and flat, last thing i wanted was to come home after a hard day and start an analytical listening session.

These headphones are probably not for you! They will produce excellent quality sound (one of the very best headphones at any price) but they really need a proper headphone amp and an excellent source to make the most of their potential and most people have never heard of a headphone amp and use mp3s...

Lets you hear your music at it's best

Just be sure your music's best is good enough! Really NEEDS a headphone amp

I have owned a pair of Sennheiser HD650 headphones for almost a year, and the sound they produce is quite simply divine. I have been producing, recording, editing and listening to music for many years and the HD650 headphones represent what I would consider to be the best in headphone audio quality.

This is very solid headset for everyone who likes to listen music!

Amazing sound quality; nice and simple desing and it is very solid

Not that good if you want to walk with in on the streets

Reference quality (good enough for me anyway!). Prefer to AKG 701s and Beyer 880s. Well made. Similar to the 600s but slight improvements such as a thicker cord --- which actually does help the sound quality a bit. Accurate. Good bass. Excellent SQ but a bit veiled. It helps if you can try it first.

This head phone suck compare to my shure scl5($250.in ebay). It look like a cheap head phone. The scl5 is a lot better than hd650 in any frequence. The price is too high for such headphone like this. It should only cost $100.00 at the most.

none

every thing
