These are not cheap headphones. They are reasonably expensive but you will more than get what you pay for.

Amazing sound; all day comfort; value for money; cord length

Makes your other headphones sound bad; need an amp to get the most out of them

Needed amp definitely and time for break in / to be accustomed with sound signature... comfortable enough..home use only as open back headphone

Was very happy with these headphones and the service from DWI. Firstly, headphones supplied are totally genuine Sennheisers which was a relief and were delivered quickly. Extremely happy with the HD650s particularly their bass response.

I was a Day One iPhone adopter, and can easily say that I'd buy one again, even though the first generation iPhone is clearly not perfect. My main complaint with the iPhone is the battery life. Compared to other cellphones, the iPhone's battery life can best be described as "barely adequate.

Very few headphones deserve to be called a true "reference" but the HD650s are in very selected company of chosen masterpieces.

The Sennheiser HD-650 is an old flagship of the company now replaced by the HD-800s. Though said new flagship is almost triple the price. The HD-650s retail at 499 US Dollars. Like most things, these do go on sale but rarely.

Light weight , comfortable to wear for long periods. Good sound reproduction . Not that comfortable to start with, but when they stretched as I said above they are .

Overall I am satisfied with the headphones but at the price I was expecting a little more with the materials used (just doesn't feel premium enough).

Nicest Headphone ever had. Worth the price.

Very light Comfortable Earcups Can hardly feel the headphone Awesome sound Way better than the AKG550

Expensive

great product; fast delivery (received within 3 days); very satisfied.
