5.0 out of 5 stars The finest pair of headphones I have ever used Nov. 14 2012
Verified Purchase
Before buying a cheaper pair of headphones, you have to realize that audiophiles everywhere will say that one of the best hi-fi headphones that all others are compared against are the HD650's. There are more or less expensive headphones that you could buy, but if you after reference quality, by which all other headphones you ever will buy will be compared to (more far worse, and few better), these are the gold standard.

I use these headphones to listen to music on the PC, so my recommendations are based on this. You need an adequate powered source to get the full benefit of the sound quality on these cans. I suggest at a minimum that you have a dedicated sound card with the ability to power 150+ohms, such as the Asus Xonar Essence STX. You can use an iPod or iPhone, but you would be doing an injustice if you didn't properly power these with an amp (i.e. Fiio E17). The other option is an external DAC/AMP combo such as the Asus Xonar Essence One. These are obviously not the only options, and i'm no rep for Asus, but they are very good PC options for quality sound output from your PC without breaking the bank.

The quality of the pads on the ears are great. They are soft and breathable, and never make my head sweaty. I can wear these for 8+ hours without any fatigue or irritation. The strap holds snugly, and doesn't feel like it is going to fall off if I move my head too quickly. Cable quality is excellent. Gold connectors with a jack adapter is included as well.

When you first hear these powered properly, playing high quality FLAC files, you will be amazed at what you hear. Because they are open over-ear headphones, you get a wide airy soundstage that doesn't feel like the sound is being forced at you.

Being a producer,composer,audiophile for about 15 years,i can honestly say these are the best investment I have ever made on headphones,they require burn in time but I was blown away listening to them right out of the box,if you are a music producer and cant use monitor speakers all the time I recommend the HD 650's,just make sure you have an amp that can drive 300 ohms,i did much research on these before I finally bought them,and now wish I had gotten them years ago. they are very well balance and let you hear things the way they were intended to be heard,incredible soundstage and jaw dropping accurate low end,highs are slightly rolled off but I prefer it that way as they will not slice up your ear drums,serious producers will adore the hd 650's,they will get you 85%-90% of the way there,the rest should be done using studio monitors,they are pricey but well worth it once you hear them and apply them in your studio,i also have Akg's 701,which in a lot of forums people said they were the way to go over the 650's and i must say the sennheiser HD650"s put them to shame,i could never get my mixes right using Akg's,Akgs 701"s are good but not in studio applications,i also read the HD650"s would sound "crappy" out of the box,so so very untrue,i highly recommend these to serious music producers,who like I said before cant use studio monitors speakers all the time,and want to get their mixes up to par,in my experiance it is not impossible to get a great mix using the"right"pair of headphones,knowledge is power,and trusting your ears,and do the final mix with a good pair of monitors

If you are thinking about getting these headphones, stop thinking and just do it. One of the best for price:performance.

300 ohms, requires an amp.

I want to call them the last headphones you'll ever need, but they aren't portable and the open design leaks sound. So...one of the last 3-4 pairs you'll ever need!

I have both the 650's and the 800's. Haven't found a better headphone for the money than the HD650's. Great low end performance. Better than the 800's.
