I bought this IEM cable as an experiment. It has proven itself to be worth its low price and more.
I looked at this and the Tripowin Danube, both being 8 core SP OCC and both being 28 AWG with a flat Litz structure. The only difference is that the Perles has a 19 wire structure and the Danube has a 32 wire structure. My choice of the Perles was specific on this basis.
Ergonomically the Perles is very good. It is very pliable, light, the ear hooks fit my ears perfectly and hold their shape and I hear no microphonics.,
I used it with an expensive TOTL IEM because I wanted to compare it to the stock cable that came with my IEM. I was surprised.
I will not go into audiophile detail mode describing what I hear. Let me just say that I was pleasantly surprised.
I will summarize by saying that the Perles offers a pleasing slightly warm musical quality which makes it very easy and satisfying to listen to. The Perles does not seem to suppress bass, mids, or treble but allows the tonal balance to remain pretty much the same. I have not been a fan of silver cables as I prefer a warmer richer timbre and silver can be too bright for my ears. Surprisingly this is not the case with the Perles. (This may not also be true of the Danube as the thinner wires and increase in the number of wires may change the Ag/Cu ratio and result in a probably inaudible shift in timing of the treble. I cannot know without trying the Danube.)
The Perles does not present the technical prowess of much more expensive cables, but it does a surprisingly good job considering its modest price. It is well designed, well constructed and accomplishes the task of providing musical enjoyment.
I will probably keep the Perles and use it for casual listening or when I am traveling. It is that good.
For serious listening or being carried away by the music I prefer, for example, a cable by another Asian manufacturer, the Fusion 1 from Effect Audio in Singapore.
For someone in Europe or the US this Perles IEM cable is well worth the minimal cost here in our Western economies.
One of these days I will probably try another similar cable from higher up the product lines offered by this seller, Linsoul.
For people with Sennheiser IEMs, note that the MMCX connectors work perfectly with the IE900.
Enjoy the music friends,
