For over a decade now I have sworn by my now discontinued Sony MDR-CD3000 headphones as my trusty live sound reference point. When I wrote an article stressing the importance of having high quality live sound cans I failed to mention viable options for the sound engineer readers to acquire.
So, the plan is to get my hands on a nice collection of top brand headphones, give them a listen while using the CD3000's as a reference and find something similar or hopefully superior. So the rules of the game at this point are:
Closed Back- The headphones I seek should be closed back. Seems simple enough but the fact is that many of the high end headphones are currently open back. This is because the smallish headphone sound chambers tends to choke off the lows and cause some negative sonic artifacts. Porting the chamber to the outside world reduces isolation and porting to the inside the muff area can add low and low mid resonance. Regardless, for us live humans, we need the sound isolation though I am not holding high levels of isolation to be imperative as that would overly narrow the options and also eliminate my CD3000 reference phone. So as long as the headphones get fairly loud, preferably rock concert levels and offer a reasonable attenuation of the outside world, I will include them.
Around the Ear - Theoretically, on-the-ear designs could work but the added isolation of an around-the-ear (circumaural) design plus the typically larger sizes of the transducers in over-the-ear headphones, inspired me to narrow the field and a bit. The in-ear designs can offer excellent isolation and possibly are capable of enough fidelity and volume, though I have never heard any that sound amazing, but for a sound engineer's reference point, we do not have the time to be shoving things in and out of our ears mid rock show.
No Internal Electronics - I have so far bypassed all the noise canceling, electrostatic and other pre amplified headphones because I am skeptical of the added layer of complexity, dead battery issues and other artifacts. The last thing we live sound humans need is the noise canceling circuit overloading from the rock show or some strange sound added. That said, I am not against considering electrostatics if I am able to get my hands on some.
Size does not Matter - Or more specifically, bigger is better. I am really looking for a 'Head PA.' A cranial sound reinforcement system capable of accurately reproducing dynamics, wide bandwidth and high level sound. It is not like we will be jogging with these things.
High Power/Volume - In my experience headphones blow out fairly often when used for live sound, mainly because I inevitably forget to turn down the headphone volume when I set them down. I am looking for a pair that handles some juice. I have found several models that are rated at 3000 mw.
Hard Clean Sound - There are two differing approaches to loudspeaker and headphone design. The home hi-fi approach where the goal is to gloss the musical flaws and present the listener with a pleasing and enjoyable sound. The other is the studio monitor approach where the goal is to expose all the flaws in a harsh and accurate light so they can be addressed. I am looking for a pair of cans that just sounds like the damn instrument I am trying to listen to.
Cost is Irrelevant - Well, it's not irrelevant, but I did not put a cost restriction on the units I am testing.
Minimize my Opinion - Since sound quality is highly subjective I will try an reduce the effect of my opinion on the selection process. All the headphones will be tested in comparison to the Sony MDR-CD3000 pair I have. My goal is to try and match or beat the sound quality, volume and frequency response of the 3000's.
So lets take a look at the reference pair and growing list of contenders. I have listed a few specs. The street prices are just a quick low mid estimate and I tried to be realistic and avoided the super cheap questionable vendors. The list price is the same as MSRP, I just used what ever I found. It is quite an endeavour getting my hands on all these cans. Fortunately several manufacturers have been so kind as to send me demo's plus I was able to raid Rat Sound's headphone stock. A few I actually purchased and some I am still on the fence about whether to to try and get them in the mix. So I listed in parenthesis the source/status.
The Contenders (so far)
Sony MDR-CD3000 - $699 List, Discontinued, 32 ohms, 104 db/mw, 500mw, 20-20K (Dave Rat, reference)
Well alright. That will keep me busy for a while. Hey, if I missed any worthy headphones as contenders and you have suggestions or you feel any of the ones I am undecided about really need to be tested, let me know. Also, if you are with a company or have connections to line up some demo cans that should be included, that would be great too.
I have started listening and testing and WOW! The diversity is mind boggling! So far there is absolutely no correlation between the frequency spec's, cost and the way these things sound. It is like the old school wild west of sonic lawlessness!
Not against testing those or any other Sony V6 offshoots that use that Sony driver.
I have not gone out to seek out them as, at least at this point, the V6 should be a good representative of that group.
Agreed, the sound is the same pretty much. The thing I was after was the isolation when using cans for a live show. The attenuation is excellent and you don't have to blast the phones to actually hear what you have PFL'd or are mixing.
I am currently using the Shure SRH-840, I have always wanted a pair of electrostatics for home use. My second fav is the Beyerdynamic. Id give the Shure a serious consideration.
good isolation, have taken a beating so far. they fold partially which is better than nothing for a closed back and removable/replicable cable. I have had one instance where the ear muffs came off on one of them but easily went back on... mmm ear muff (sounds pornographic)
Those Shure's are built well and the removable cord and extra earpads were both nice features. As far as how they fair sound wise compared to the others, well, that will have to wait till I get farther along.
Hmmm, yes, I have been looking at those and they look like strong contenders. Unfortunately Denon refused a request for a demo pair as Rat is not a dealer for the consumer line. But... I will look into it further.
If you can find a pair of Beyerdynamic DT-150, then I hope you can include them in this test. They have been my #1 choice for years now, would have been interesting to know how they perform compared to your current lineup.
beyer DT770 fries super quick. "high power/volume" came into effect as the headliner engi told me after the show he now has a onesided pair of headphones. after hitting "solo clear" the mix was just clobbering them for 30 minutes as they sat on some aux sends....
too bad the house engineer who handed the cans to me in the first place neglected to tell me they weren't the house 'phones and i was in too much of a hurry to ask =|
(awkward first day of tour that was...)
all that said, Audio Technica M40 fs?
