Review: great product - I used this OKCSC ETYMOTIC lPX T2 8-core upgraded OFC audio cable for a live gig in front of a crowd of about 10,000 people, and it performed flawlessly. The cable feels solid and well-made, with no stiffness or cheap coating. Connections were secure and stayed locked in throughout the performance, which is critical in a live setting where any failure is noticeable. I had no signal dropouts, crackling, or noise issues during the entire set. Sound quality was clean and consistent, with no noticeable loss compared to the stock cable. The upgraded OFC wiring seems to do its job, especially for stage use where reliability matters as much as sound. Overall, this is a dependable upgrade cable that held up under real-world professional use. If you need something trustworthy for gigs, rehearsals, or frequent use, this cable delivers.
Review: A really good cable, length options would make it even better. - Not that it really matters, but I purchased the 4.4mm connector version. I've purchased many different 4.4mm cables from desertcart, honestly almost all of the 4.4mm to dual 3.5mm cables listed under $35. While I personally don't hear any difference between them like some people claim to be able to, with the exception being cables that don't work correctly. I've been on the hunt for a cable that fits my particular desires. Which is a straight 4.4mm connector as my setup does not benefit in any way from a 90 degree connector, no two-wire twist cables, and uniformity in materials/color on the connectors/split. Beyond that I was actually skeptical that the cables would actually have the full length injection molding at the connectors to anchor the wires in place. Honestly, I figured as a cost saving measure they might have just put a glob of hot glue under there and called it good. But to my surprise the aluminum cover is still able to be unscrewed and pulled back and sure enough the connectors all have uniform injection molded strain reliefs. This makes me feel like the cable will hold up well over time as each connector has about an inch or so of the cable encased in plastic which not only acts as a pretty good strain relief which is even reinforced by the aluminum cover as well, but because all of the solder joints are fully encased as well it should help with corrosion resistance in humid environments. Color me impressed, well made indeed, especially at this price point. The only thing that I personally would want more from this cable would be length options. While a ~4ft cable might be perfect for some people, I'd personally like one closer to 6ft. The 5 star rating system with not halves doesn't give enough definition, I would probably rate this cable as a 4.5/5 stars simply because I want it to be about 1.5-2 feet longer, but it is definitely deserving of a rating above 4 stars. Should OKCSC add additional length options, or list another longer cable using the same materials, it would be a 5 star.

### ⭐⭐⭐⭐ They're great little cables, but be aware of accidentally unthreading the connectors!
*by E***Y on July 13, 2024*

These work great for my IE 500 Pros & my ifi go blu. No noticeable audio quality difference to my ears, and the texture of the cable is easier on my ears than the stock cables. There's something I discovered about the connectors on this particular variant. These are Pentaconn Ear connectors, and if the housing on the IEM end is twisted while the connector is attached to your IEMs, the gold connector itself will begin to thread out from the housing. I might try adding a tiny drop of Loctite to the threads, but it's not a big deal for me. I imagine it would matter to someone who's performing on stage and moves around a lot. Overall, great cables, might be better with a tiny bit of blue Loctite.
