    Bulky, Expensive, Sound leakage

15 October 2013

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

7 September 2008

The HD 650 has been Sennheiser’s flagship audiophile headphone for several years now, but it is only recently that the firm decided to buck contemporary pricing trends to reduce the product’s list price from around $600 to $500.

I was so excited to finally get my hands on the holy grail of mid-range headphones, the Sennheiser HD650... or so I was lead to believe.Facing facts, we're looking at a relic here.

    Comfy; Good-looking; Nice big sound stage

    The greatest overall disappointment I've ever experienced in audio devices

26 June 2009

By default, I've become "the headphone guy" in high-end audio. I don't quite understand why other audiophiles don't fess up that they listen to 'phones too. Maybe it's a macho thing, like the Butt Blaster at the gym -- you never actually see guys using it, but you do see them furtively exiting the...

The formidable Sennheiser HD 650 headphones are fit for a king--and have a price tag to prove it.

  • +

    Sennheiser's flagship headphones have high-tech styling, extraordinary bass response, and an extremely comfortable design.

  • -

    They're heavy and very pricey, not to mention ill suited for use with the iPod.

INTRODUCTION I have had a hankering to see if I can find a better pair of headphones. Primarily, to use as a reference to evaluate source components and pre-amps, and also for personal use. I had purchased a Sennheiser HD497 several years ago, for about $50 USD and it has served me well so far.

I have owned these headphones since Aug. paired them with soundblaster X7 Limited edition & they sounded good, I thought the base was soft but overall sounded good. Then about a week ago they started to break in & the base is much better & overall sound is even stronger.

  • +

    Incredible range, open sound stage, got to wonder how great are the HD 800's

  • -

    Must use a headphone amp. Have patience, need a long break in period.

Honestly, this headphone can re-define the rules in terms of music clarity. I have experienced many different studio class audio products but what Sennheiser created is a magnificent piece of art.

    Comfortable, Durable, Good Bass, Good Value, Great Sound, Stylish

    Flimsy Construction

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

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.

These headphones have a pretty good reputation among audiophiles so I figured that I would give it a try. The first thing I noticed is these are some huge headphones. I mean, I guess it’s expected since the audio drivers are high-end, but damn. Aside from the non-subtle size, …

Jus got the hd650's about 2 weeks ago...I've broken them in, and let me tell you, they are the closest thing to being at the recording studio with the band!! I mean, they sound so real, and authentic, that its unbelievable!! i mean, what can I say?

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.
