They are not TB5 compatible though, and if you are going to drive monitors through it, or connect external GPU, 120Gbit (TB5) is much better than 40Gbit TB4 gives you. If you are willing to pay a bit more, consider TB5 cables from CalDigit, StarTech, CableMatters, or Apple.
By chance, has anyone tested Cable Matters' cables?
I just bought a couple of their Thunderbolt™ 5 cables. They seem like a reputable company that would make their cables true-to-spec. Thanks in advance!
I bought a 3-meter long USB C cable from them for data and display transfer, which turned out to be the only USB C cable of that length capable of driving my display at its full resolution and framerate. However, after a year of use, it stopped transferring any sort of data. So while they're probably up to spec, the quality isn't necessarily what their pricing may suggest.
Support allowed me to send it back for replacement as a "one-time exception", though I was well within the common 2-year warranty period in the EU.
We had good results testing Cable Matters stuff here at work, but that was for non-critical use so I didn't go too hard on the tests. (Actually, I didn't go too hard on any of it since it was mostly make-work from a manager trying to cause trouble, but still....)
I was quite impressed by GlobTek (available at Digi-Key) and have been buying those when I need something nice. Their USB-C line are some of the best I've seen, not that I'm a connoisseur.
I've not spec tested them, but astronomy gear is notoriously picky about USB cables and since I switched all of my cables to cable matters a lot of weird behaviors just stopped happening
They are excellent.
They also crackle out of the package, or at least the 5 I got did. Kind of sound like the thin glow sticks a bit.
Could that possibly be shielding?
I can't say I've seen it on USB-C-esque cables (except maybe a thunderbolt cable a while back?) but I've seen some cables use a type of aluminum or mylar-looking foil between the outer rubber sleeve and the inner sleeves and wires.
That shield is a drain wire combined with either a woven braid (most effective at lower frequencies) or a solid aluminized mylar foil (most effective at higher frequencies), or, for the best cables, both together.
A USB-C cable really should be shielded. Here's a cross-section I took of a nice full-featured USB-C cable: https://ibb.co/svR5Yvyr . You can see the VBUS/GND (fat red/black), the SS pairs (white plus red/blue/yellow/brown, each one foil shielded on this cable), the USB 1/2 pair (white/green), and then the CC and SBU stuff is the remaining wiring. Notice how not just the whole thing is braid+foil shielded, but the SS pairs are individually shielded; that's really important at these speeds, and what you want to see on a good cable.
Compare with two USB 2.0 cables: https://ibb.co/BHz4v1mx and https://ibb.co/GfpJmgbx ; the first one has the shield braid, as it should, but everything else is nicer on the second one. Cables!
I have a few of these cables, pretty decent although I think the USB-C ports are a bit too thin? They feel lose in multiple of my devices
I managed to get a few and so far am impressed. They are definitely on the chunky side but that probably comes with the durability
My concern is stiffer cables are likely more likely to rip USB ports off the PCB. A lot of devices provide very little support to the USB port which is basically just hanging off pads on the PCB, so a stuff heavy cable could provide a lot more bending force to rip it off.
Phones and macbooks have it done right where the outer portion of the port is built in to the device body, but most other devices don't do this.
They’re chunky, but very flexible. There’s basically no memory effect to them either, so they don’t try to curl up on their own.
