With the pure silver cable, the highs became just sufficient to lift the veil and give life to every instrument

The cable is replaceable too

I'm stuck with a useless pair of >$300 headphones, unless I want to shell out more money to buy an expensive aftermarket cable.

With this pair of Senns you will need a high end amp, and a high end sound source connected with appropriate interconnect cable

But it certainly is not a prerequisite to fully enjoy the wonders of the HD650 (quite apart from the fact that the Cardas cable is a hideously ugly thing to behold, makes the phones far more cumbersome to wear, and unlike the thinner, more supple stock cable causes contact noise).

FIX THE DAMN CABLE, its brittle as hell and will break if you move around a lot

I would highly recommend a pure silver cable

I'm not an AUDIOPHILE, I also don't believe that if you put a $2-300 cable it will significantly change anything unless the cable is damaged.

Detachable cable

I also recommend a shorter replacement cable so your'e not walking around with 8 feet of cable in your pocket

To sum it up:PROS:*Cosmetically, this is a stellar headphone*It is very sturdy and parts are interchangeable between the 600's and the 598's*The cable is detachable, why don't more companies do this?????*It comes packaged in a nice sturdy box that you can use to store them in*Great for people that like an enhanced bass curveCONS:*$499 is far too much for a mid-fi headphone, especially when the HD600's often go for around $300*The colored sound disqualifies this from being Audiophile or Reference in my book*The foam in the box smells funky, but I find this is the case with the HD600's as well

Other manufacturers have come up with better end connectors for headphones with detachable cables.

I don't care what kind of DAC you have; a cheap usb cable is going to flatten the soundstage with a steamroller and eat up any sounds below a certain level, because the HD 650 will gargle and choke on every packet error your DAC processes

The cables are removable, and after some research, I found out that there are third party cable makers that make replacement cables (that are supposedly superior than the stock cables) for HD650, but those cables cost more than a hundred dollars, and I doubt replacing the cables will improve the sound noticeably

With the pure silver cable you can experience a huge improvement for the HD650

So to get full milage out of these beauties you would be wise to buy a better cable which raises the price a

The long 3m cables are a mess to handle for everyday

Detachable cable is a plus, got a short 3.5mm cable to go with it

I also despise the DT880s fixed cable design and appreciate the HD650s detachable cables better

My only "wish" is that I would have preferred a longer cable

I am experiencing a really exhilerating improvement for HD650 after I replaced the stock cable with a pure silver cable.http://www.amazon.com/gp/aw/d/B00F2JG4P4/ref=mp_s_a_1_3?qid=1425746558&sr=8-3&keywords=hd650+silver+cable&pi=AC_SY200_QL40&dpPl=1&dpID=317K1rw6nLL&ref=plSrchI'D LIKE TO HIGHLY RECOMMEND THIS CABLE for any HD650 user

Another point I would like to add is about Balanced amps and cables

I should say I'm very skeptical of many headphone "good ideas" - expensive cables, "burn-in," and headphone amps have never produced a superior sound, in my experience

It's an easily affordable PURE SILVER CABLE which placed the HD650 onto a totally new level of sound

Replaceable cables - yep

No inordinate amount of wand waving or dimensional convolving with magic cables or luxury amps will ever change the HD 650's fundamentally flawed sonic characteristics

HD650 doesn't come with best sound without doing any thing, however, it sounds fantastic when you pair it with a good amplifier and cables

Pro'sAudio is so clear and has very little fatigueVery lightDoesn't get hotConsAveragely fragileWould like more cable optionswould like to see an update to this headphone by adding more durability & a better cable system

I've had to replace the cable twice in 6 years because I've ran them over with my computer chair countless times and eventually they just stop working lol, but at least the cable is very easy to replace and not very expensive

Those who enjoy old jazz would try a pure silver cable

I immediately felt guilty and maybe crazy for buying such an expensive cable, but then I plugged it in.

And the pure silver cable provides very accurate timbre for almost every instrument

The cable is plenty long enough and replace/upgradeable if the desire ever came

--Almost two years after replacing the stock headphone cables, that immediately broke, I'm now forced to replace the sturdier cables that should have come with these $500 headphones to begin with

Another great feature is the detachable cable which allows for aftermarket enhancement by upgrading to a balanced configuration or high end SE cables

The Cardas cable is the most amazing cable I've ever owned.

The cables are interchangeable & upgradeable.

RECOMMEND A 'PURE' SILVER CABLE for HD650!!Thanks for reading~!!

Actually I also have bought a silver-plated copper wire sold at Amazon and Ebay which is by no means recommendable with regard to the pure silver cable

I owned a pair of HD595's for several years before I accidentally broken them due to the stupid long cable.

What if you snag the cable on something

If you like a laid-back, really mellow phone with no personality, you might like these

I am etiher getting accustomed to the sound or they are improving as I use them more

In excellent condition as well--almost as if they were never opened :D Thank you!

So I looked at Sennheiser other phones as well as

and I absolutely love them months after purchasing just as much as I did the first day.

The HD650's may not have the fancy technologies of orthodynamic or electrostatic units, nor the pricey parts and accessories, but they definitely sound nearly as good and even better in some ways

I have found they sound marvelous with vintage Marantz receivers that can be obtained inexpensively, as well as from modern dedicated headphone amps

Id hold out for another crazy B&H or Adorama deal on

For softer pop songs and guitars, "Acoustic" brings out the lighter more ethereal tones, but stay away from the flattening abomination called "Pop"; if you want a fun punchy pop song, I'd recommend "R&B", it may be a bit on the smooth side bass-wise, but it does the job well

Even a colored one may often be difficult to tell apart in a Double A/B Blind Test

The headphones were nice enough to put the Braille letter L on the left side but the cable has no such thing.
