OE Audio 2DualCDC IEM cable

General Information

37*0.06mm Oxygen-Free-Copper Strands in each cord, with a total of 148 strands.
Various connector plans, for MMCX and 2Pin earphones.

2Dual represents the structure of the cable. The conductors are Teflon coated and accurately twisted, and covered with medical grade TPU sheath, then twisted again.
This structure has the advantage of 1. Effectively shielding interference from both internal and external electrical signals. 2. Preventing the conductors from being oxidated 3. Providing an experience of comfort, good looking, and soft.

New Head-Fier
Cable Problem
Pros: Good sound
Cons: poor connection
I have some 6xx headphones. My Asgard 3 needs an adapter to fit the stock 6xx headphone cable. I have noticed when I plug the cable in until it stops in adaptor the sound is off. When I just pull the cable out just a pinch the sound is full and gorgeous. Should I replace the cable or the adaptor? Thanks for the help.
Believe it or not the 1/4 inch adapters are of various specifications. Meaning that you should buy a few...as chances are with other 1/4 inch to 3.5mm (I’m assuming that’s your adapter) will often sit better to connect the signals. I have had this happen on rare occasions also. Just try different adaptors, no need to replace whole cable. The interesting part is with you it’s either all on or off maybe to one side? The really serious situation is when it’s almost not noticeable, but a slight sound degradation is occurring! That’s almost hard to spot!
Thank you.

Design / Build quality

The OE Audio 2DualCDC cable presents a really good mix of build quality, ergonomics and, subjectively, aesthetics for its sub $100 price. It is very light and compact, easy to wrap and store. The audio plugs and IEM connectors are well covered by a strong PU material and have an extra metal cylindrical cover surrounding them. Also compact and well finished. The y-split section has a PU square body and extra added metal plate with the OE logo on it, and a soft plastic cable slider attached. This may not be as miniscule and thin as the Linum cables, but it is more robust in terms of build quality, more attractive, and overall could make a good alternative to the more expensive SuperBaX. The cable features no memory-wire or fixed guides, which I personally find more comfortable and versatile as it suits all kinds of IEMs. Cable noise is not an issue with the 2DualCDC.

As can be seen on the picture, at its core the wires are twisted in a specific way. There are 37 copper wire strands of 0.06mm thickness each and organized in a so-called “concentric-lay” structure. Basically, it consists of one strand in the core which is then surrounded by three extra layers. Whether it is just some marketing ad or real special structure that has a true impact on the technical sound performance we won’t know, and not really care, either. Unless compared to a more standard wiring of the same type and count, you’ll never find out the improvements of any ‘special’ inner wire geometry. That said, the OE cable has some impact on the sound quality, covered in the following section.

As an extra accessory to the OE Cable (or any other cable), there are these connectors’ adapters. Available in clear or black color, and in both 2pin-to-MMCX and MMCX-to-2pin options. These are probably one of the smallest, most compact adapters available right now, simply built and very light. The ones here are the 2-pin to MMCX option. The 2-pin sockets are quite tight and attach strongly to the cable pins; some strength might be needed with some cables. The MMCX plugs, too, provide a solid connection to the IEMs sockets. Tried with the Solaris 2020, A8000 and Fir VxV and all work perfectly and do not rotate freely. The length of the adapters is ~11.5mm, and once plugged to the IEM, the main body is just ~8mm long, so won’t make the cable too bulky or the cable plug much longer.

Sound impressions

As usual, the changes or even improvements of audio cables are not very easy to discern and the impressions will also depend on the earphones and/or audio sources they are tested with. This OE Audio cable is no exception, but still there are some differences compared directly to each in-ear earphone bundled cable, and even a bit of gain in certain points that are worth noting. First of all, this all-copper cable trades some transparency and neutrality for a bit of added coloration to the sound, and fortunately not at the expense of clarity and resolution. I found similar results with a variety of models, from single dynamic, balanced armature and hybrid drivers. And the OE Audio adapters, 2-pin to MMCX, allowed the cable to be tried with an even wider range of earphones.

The bass sounds a bit tighter and more refined in its layering. There is a slight extra richness on the lows, perceived as having more fullness on notes, especially at mid-bass region, and even so, there is better separation on low instruments. I find this to affect the transition from lows to mids in where the midrange is less neutral, less balanced. It is richer on its whole but kind of less natural. Also, the low-mids are less leveled next to the upper-mids that gain a tad more energy and sparkle. At the treble, too, the gain is mostly at the lower-treble, but nothing really noticed at the rest of the upper frequency. No real improvement on stage expansion that can be noticed, but despite the kind of coloration of the OE cable, it actually gives some extra air and clarity.
