With the extensive description on your site, I did not feel the need to do more research which I tend to overdue. I had a terrible buying experience a few times and vowed to never go back. I called the Help Center that Sonic offers to have a few questions answered about these headphones.

Sennheiser makes some very nice audiophile approved headphones. The HD600's are definitely one of their top products. A very nice set of cans that will allow you to listen to a wide range of music, without a fatiguing experience. Pros: + Impressive Sennheiser soundstage presentation...

I was never an audiophile, I just knew if I didn't get these on sale while seeking a quality upgrade, I would always wonder. Now I won't go back. I ordered from the Newegg marketplace and had no issues whatsoever.

Incredible sound; Everyone I've shown them to has been blown away

You MUST have an amp for these; I was able to use them with the volume@100% on my phone, but it wasn't desirable; I knew this going in, so not really a con, just a drawback; (I do have an amp) If you don't have an amp you might want to check out HD598 or Audio-Technica ath-m50x

These headphones still are some of the best ever made. Most limitations are due to hearing acuity rather than HD600 performance. I have multiple sets of headphones including the HD 800's. The HD 600's are my favorite and most used.

Produces the sounds of all genres of music as recorded; You hear what was intended to be heard

Headband could have be in different colors and patterns

These are very good headphones for the money, quite balanced sounding. Yes there are some headphones which can do this and that better technically, but somehow not as balanced overall and not as natural in the midrange.

Here at MajorHifi, we review new and old headphones alike - whatever we can get our mits on, really. And sometimes we forget to review certain headphones because they are already...

I purchased the Sennheiser HD600 after researching headphones on the net. I wanted a well made, comfortable, and sonically accurate headphone that I could connect to my Onkyo receiver. This unit is very impressive and does not disappoint.

These headphones are incredible! Vocals are extremely focused and smooth. Acoustic songs sound particularly excellent. The HD 600s bring out details I've never heard before, tracks like 'Get Lucky' (Daft Punk) and 'Better Together' (Jack Johnson) really shine.

I bought these yesterday as a replacement for my HD 598se and already love them. They sound excellent with my Schiit Magni Amplifier and Schiit Modi DAC. The only gripe (minor as it is) I have about them is how long the cable is, but since it is removable I really do not see it as a con.

These headphones are one of the great ones, smooth sounds on highs and lows, no colorations at all, just pure clean sound from the highs to the miids to lows! In my opinion they rival or match a pair of 35 thousand dollar speakers!
