Sennheiser HD 650 - Audiophile Hi-Res Open Back Dynamic Headphone

otherwise its useless.

I did much research on headphones and cables and headphone amps to drive them.I had to do all this on a small budget.I got the HD 650 and the Cardas cable upgrade 15 and took a giant leap and got the Creek 21se headphone amp and the Audioquest King Cobra RCA and hooked it up to the CA Azur 640c v1 CD player and replaced its stock cord with the Audioquest NRG-2 power cord and removed its black RF ferrite noise stopper.Also got the Monster SW200 surge protector with stage 1 clean power circuitry to plug the CD player and the amp in to.Also added three model 2 vibrapods for CD player.Next it takes quite a long time before I could reap the benifits of these combinations.In other words there is a break in period for most of these purchuses.After playing a CD for an extended period of time of about 80 hours Ive reached what what everybodys been raving about; the ultimate nirvana.Its just miraculous the sound quality that comes though these set of headphones.You dont know what you missing just listening though speakers.These headphones are far more engaging.Its worth noting that if you not able to make some of these sacrifices you should look at another headphone.It takes alot of power to drive these headphones and nothing short of an amp just wont do.When all is said and done it set me back about$1400.With this large investment Im thrilled to have years of high quality headphone listening.Update:Four months later:Incredible,Extraordinary,Phenomenal.

My last set of Sennheiser headphones are 30-yrs old, still work very well but dont reproduce the heavy lows of my new symphonic metal, so I bought this 650 series and am well pleased with the rich sound. Ill give the old ones to my grandson. These do not have noise cancelling, a feature I do not require, however they have open backs which keep my ears cool and resist blowing my ears out.

The sound quality is well worth the price.

I love how these sound.

今までいろいろなヘッドホンを使っていましたが、全て2万円以下のものでした。今回奮発してHD650を購入してみました。(私の住んでいるところはとても田舎で試聴はおろか実物すら置いてありませんので皆様のレビューのみが頼りです) まずエージングなしの最初の一聴から驚きました。オープン型なのに凄い低音〜高音まで素晴らしく出ています。これでエージングが済んだらどんな音になるんだろう?と期待しています。窓を開ける季節になるといくら一戸建ての家でも大音量で音楽を聴く事は出来ないので壊れるまで使いたいと思います。

What can I say but excellent, excellent, excellent. They only get better with more playtime, and they scale so well with a quality desktop amplifier. I mean come on Sennheiser, seriously though.. What did you guys do? invent a time machine and steal technology from the future? 11 years running and still a monstrous set of headphones, meaning they devour anything else near its price range. I feel compelled to tell you reader, to buy these headphones and accompany it with a quality desktop amplifier, because it will change your perception of music forever. This is all of course with a high quality lossless song to play on them. Truly the benchmark to which other headphones are compared.

Great headphones for mix and mastering as they are quite accurate. For producers/audio engineers would also recommend sonarworks headphone software in combination for a great sounding mix if your forced to work on headphones

Absolutely phenomenal, some of the most stunning headphones Ive had the pleasure of using.

Beautiful quality - from the moment one opens the padded storage box one can see/feel the high quality of the materials and components. The 650s feel rather snug at first wearing (as many others say) but are surprisingly easy to wear nevertheless. I was amazed during my first hour-long listening session to hear the phones gradually loosen-up/break-in - like a flower unfolding the dynamic spectrum became clearer, wider and more pleasing as time went on. After an hour theyre sounding good, but I anticipate that theres more to come! Beautiful rich and clear, theyre simply a joy to listen to.
