Beyerdynamic custom one pro a.k.a. COP

Beyerdynamic cop has been one of the more creative product coming out of Beyer. These are unique in a sense that there is flexibility involved, cosmetically and audio.

Outlook / Appearance

This is the portion of the COP that has really attracted my attention and love. The can can be custom designed, as most parts are replaceable Besides that, there is the adjustable bass port that will change the bass portion according to which level it is at.
Couple of varieties can be designed

Adjustable bass port on each side
The bass port will be discussed in the sound section.

Cable weight is quite light, not as heavy and dragging as the DT770 250 ohm i have. This is due to the fact that it is using straight cable rather than a twisted cable. 

The end tip connecting to the amp is still using screw on 3.5mm-6.5mm socket type.On the other side, connecting to the can itself, is using a lock mechanism 3.5mm cable. This makes finding custom cable a tad difficult, unless you sand off the lock.
Lock mechanics
As you can see here, there is a little pop out on the hole, where the cable will fit and clip into. Getting rid of this will ease cable finding, but i havent tried to do so.


This is the section where we will start discussing on the bass port as I mentioned just now. Each bass port has it's individual amount of bass. It varies from port 1 with a tiny circle as a mark for closed port, least bass. Then it goes up till port 4, maximum amount of bass available.I will discuss the effect of each in one song repeating over and over.

Port 1: This port is for some bass near to none, suitable for people who thinks bass will knock their heads off. Things get pretty flat around this port. Vocals are more appearing, and is generally declared flat on the treble and bass part. This will make you wonder where did the bass go to? hmm..

Port 2: This port is the port that I generally use, as there are just enough pronounced bass and will not be a hard beater. Treble is smoothed out a bit for more enjoyment. Vocal is dropped back a bit.My favourite port to use.

Port 3: This is the heavier bass port. Bass get more appearing than the port 2. Bit by bits of the bass drum can be heard clearly. Male vocal somehow become thicker and even more laid back. Treble is getting lesser by the extent.

Port 4: Port 4 is the port I normally will use only with gaming, as the bass is quite something that packs drama into games. Explosives and etc becomes so fun to listen to. Music wise, well, I don't use them, how about others? comment a bit?

Soundstage: Generally the soundstage doesn't go through significant change.


All I can say about the pad is sweat. Whole lots of it, for a location that is relatively hot. Isolation is better than the velour pads that Beyer used to use. Clamping force on the head is quite loose. Not much force on it.

Final thoughts

My suggestion for people is do give a chance to listen to this can carefully on each port. You will be amazed on the creativity that Beyer has put into this unit. The cable lock mechanism may be a draw back for people who wish to use custom cable. Small sized low profile jacks might fit without any alterations to the lock.

I myself do love the creativity that Beyer has on this one, and the sound is not too bad, it will definitely suit the mainstream users. Change the pads, change the plates, change the cover, change the headband, change the cable, thats almost everything you can change for a street look.
