post #16 of 136

Hi!

 

I've tried it on cheaper phones, but i'd recommend against this step. The paper adds resistance to air flow and removing it (generally) makes the driver undamped and more, the backwave could be ruining the sound quite a lot.

Top on modding the CAL

Remove the back cover for easier and more precise measurement of dampening material. You do that buy unscrewing the two additional screws holding the back plate. I hope this hope.

BTW, this mod really works well and a recable its day and night difference for this headphone. I can say its 95% of a stock D2000/D5000!

I am also thinking of modding my CAL!s using this method.

 

Will it make the bass a bit more forward and punchier?

That pad lift mod is genius, I'll have to try that soon with my CAL! as well... like you I notice parts of my ears are touching the insides.

I replaced the pads using my Nokia's Bluetooth headphone pads (Nokie BH-604) and it works perfectly. Noticed some changes in sound and is much more comfortable.

Are there any methods for the headband? I find that the top of my head gets too much pressure from the lightly padded headband and it gets uncomfortable wearing these cans for more than 20 minutes even... anybody else have this issue?

These babies deserve a recabling too.

Hi!

 

Yesterday I finished a couple of various stuffing in the earcups.

 

The best, IMO, is fiberloft piece, thin and fluffy, and nothing else.

Adding foam, wad or felt pads decreases soundstage width.

 

 

Some people say CAL! has too little bass, I found the stock quantity of bass too much for me. There's been note by someone who opened more holes on the rear side, or removed paper ring altogether, promising with increased airflow tighter bass, and speaker-like sound.

I must  say I went the opposite way.

 

I tried to cover one or both holes on the driver's back - picture below - with yellow paper tape.

 

With both closed, the sound is too thin.

But, if I covered only 1 of them, I decided to cover the rear one in each cup, so the airflow will occur at the same - front side, the IMO overpowering bass is tamed significantly.

Mids blossom and the bass tightness improves a good deal.

 

The change is very significant, my wife made me laugh, she first thought i put hd600 drivers in there...(she loves my HD600) :-D

any of this mod improve CAL isolation?

post #26 of 136

Hi!

 

I found they natively are quite poor at isolation, no matter what you stuff in the earcups.

They clamping force is too weak to allow proper isolation from outer world.

 

There's always less soundstage with stuffing the cups (foam, dynamat...) and also weight penalty - they become a quite a bit heavier, and, given the thin headband padding, can become uncomfortable to some people.

I'm gonna try adding some felt to the back of the cups, as dynamat may be too heavy. I'll give some thought to stuffing with polyester batting.

Other satisfied CAL owners are welcome to contribute or share their experience here. And of course, anyone else who have some inspiration for modding or just want to comment should do so as well. Posting pretty photos here of your CAL either alone or with things such as amp, DAC would be nice too.

 

Review

First of all, I haven't owned the CAL for as long as many of you. It's been about 6 months give or take, but the headphone is fully burned in. To be honest, I liked the CALs straight out of package as is, so any mods I have performed are only intentions to perfect it.

 

This headphone is deemed comparable to M50s by many, while a few even went as far as prefering it to D2000 and D5000, HD650 and Ultrasone Pro900. Crazy claims you say? Maybe... I guess I will never know since I can't afford those high end products.

 

CAL is famous for its musicality, slightly V-shaped sound signature, so it can't be be considered "technically" great. My old poll revealed that a V-shaped sound is only second to neutrality in terms of popularity, therefore I can't imagine anyone would hate the CALs. However, some people have disliked, what they describe as fuzzy/boomy bass, yet there is a fix for them (see the dynamat mod).

 

My first impression was that it blew me away. It has plenty of bass, good mids and sparkling treble. The low end and the highs both extend quite far; to well over 16kHz. It's recommended for games and movies, as I'm a more of a movie person than a music lover I decided to check it out. For a close-back, it has a wide and deep soundstage with excellent 3D imaging.

 

It came with a pouch, a 3.5mm to 6.5mm adaptor and a 1.5m extension cord (a bit fragile and thin nonetheless). The impedance is only 32 ohm; thus very easy to driver. They are circumaural to me (semi-circumaural to non-average ears). Unfortunately, the price used to be cheaper before I bought them, and after as well. Nevertheless, it still is one of the must buys for the best bang for the buck; perfect for beginners and cost conscious budget audiophiles alike.

 

Mods

The well-known markl mod, orginally to D5000 from here, and specifically to D1001 from here, consists of applying sound deadener to the inside of the cups and on the drivers; putting fiberloft in the earcups, stuffing fiberloft to the pads (only D5000), and additionally recabling.

 

Sound deadener

I applied Dynamat Xtreme that I bought from a fellow head-fier to my CAL. To me surprise, the Dynamat is not that light in weight due to a thick layer of tacky stuff (like blu tack). Warnings to those don't want their headphone to weigh any more than they already weigh(note: CAL is of the of lightest full-size cans, weighing only 210g).

The back of the cups is the tricky part, because I didn't manage to take the cups completely off the headband. All in all, it took me more than 2 hours to get this modification finished, shame on me.

IMG_6164.jpg

 

The mod is surprisingly good. It makes my CAL almost sound like a completely different headphone, while retaining most of the signature. Punchier (tighter) bass, more foward mids, not much change to the highs, I feel there is better imaging and a wider soundstage. I didn't notice any reduction in bass quantity though.  It took a little while to get used to the more in your face sound (the next mod on the pads cancels out this effect more or less IMHO), as I would imagine it's due to less false bass due echos/vibrations, so I can hear everything clearer. I reckon this is the next best thing to buying a much more expensive headphone, and I can't think of anything else that would improve the SQ so drastically (be it amps, DAC, cable change, or even EQ)

 

However, it is not easily reversible as I had first expected. It was hard enough to apply the Dynamat already, that it took a long time to measure, cut, remeasure, recut, and implement it. I'm sorry to say that I forgot to make some numerical measurements to provide you with the lengths and widths for this mod.

 

Pad lift

Inspired by this thread I found yesterday, I executed a second mod to lift up the pads so that the headphones/speakers are more away from the ears. No matter how comfortable the CAL is, I always found the inner parts(in front of the drivers) touching my ears ever so slightly. There is no easy way to stuff the actual pads as they are completely sealed off or to stuff the back of the pads as there is no room. A foam can be added to the inside of the pads.

 

Instead of soft foam used in the other thread, I choose to cut up some cheap mousepads laying around the house. You can get them for free from many places. I peeled off the thin blue layer with the logo, so that only a dense/firm black foam is left.

IMG_6170_resize.jpg

 

This time I measured the dimensions for you convenience.

IMG_6171_resize.jpg

 

Left: no foam; right: lifted with foam.

IMG_6174_resize.jpg

 

Left: before; right: after. As you can see, it won't make it look like as thick as your couch. It's really a tactile rather than asthestic change.

IMG_6165_resize.jpgIMG_6179_resize.jpg

 

This eliminated the problem with my ears touching the speakers, as well as increasing the soundstage/headstage. It's using the same principle as holding the headphones some distance away from the ears, but without the loss of bass.  Not only is the JMoney Audio lambskin earpads are as expensive as the CALs themselves, the pads also don't fit the CALs since they are designed for higher-end Denons. I say this does the job just as well at minimal cost or no cost at all. Both mods have increased the weight a bit, especially the first one; and made it a bit hotter (perhaps pschological). But I still think they are reasonably light and comfortable. I am even more hestitant to upgrade now; good for my wallet really (no "sorry for your wallet" sort of thing on head-fi, a big plus!).

 

Taper mod

Like what markl originally did to increase one side of the pads more than the another to align the earpads to the angle of the human ears, this is a variant of his taper mod. However, the effect won't be as dramatic or apparent as R10 or HD800 where the placement of the drivers is designed that way. This will only make the plane of the headphone less "backward-facing".

 

Carve out a third foam padding, slice it in half as follows.

IMG_6184.jpg

 

Because I ran out of superglue, I just put each half to the sides that are behind the ears when worn.

IMG_6185.jpg

 

Add the foams from before on top of the "arches" to creat a slope for the plane

IMG_6191.jpg

 

Edit: I reverted the taper mod though, as the extra layer was stretching the pads to much. However, I am still keeping my original pad mod. I didn't find it to have much effect to begin with anyhow, It was only to be faithful to the Markl mod.

hi, i will do this mod. i know there is lot of bitumen based damper, but i dont want to experiment with other materials. my question is : are these ones the same that you used: 

http://www.ebay.com/itm/DYNAMAT-Xtreme-License-Plate-Kit-19100-NEW-FREE-US-SHIPPING-4-x10-102mm-x-254mm-/271045543712?pt=LH_DefaultDomain_0&hash=item3f1b92c720.

maybe you mention the thickness...? in mm please. thank you!
