Review on 🔌 Corsair Thunderbolt 3 Dock TBT100 - 85W Charging, Dual 4k 60Hz Support, 2X HDMI, 40Gb/s, USB-C Gen 2 (15W) x2, USB-A 3.1 (7.5W) x2, Gigabit Ethernet - Mac and PC Laptop Compatibility by Mark Morrow

This is a fantastic dock and did everything I wanted it to until I tried using sound. I'm using this with a MacBook Pro I bought in 2021 (four Thunderbolt 3 ports), two 1080P monitors via HDMI, Ethernet, a couple of USB-A devices and power. For that, it works fantastic and I've had no issues with unrecognized devices or monitors in the wrong places or misaligned. I want to give this dock the 5 stars it deserves. Unfortunately, either the power supply or the circuitry carrying the power is very messy and always causes noticeable artefacts in the audio output (when using external speakers; this problem was not noticed when using simple in-ear headphones). These artifacts are always present (in the form of faint "lint”) regardless of volume, and become more pronounced ("crackle”) when the computer does something (e.g. page animation). Also, this poor quality is independent of the audio output device; I've tried the 1/8" TRS connector on the dock and the connector directly on the MacBook, a high-quality USB audio interface with multiple inputs and outputs, and even a professional-quality USB box, each with balanced and unbalanced ones Cable. (This is definitely not a ground loop issue). I confirmed this by plugging in the dock and an Apple 87W charger at the same time, and after about 1 minute (after turning it off) the audio was crystal clear; When I unplug the Apple charger, the noise comes back immediately. When multiple chargers are connected, the MacBook will run on the most powerful charger available (you can check which charger is being used in the System Information app; this dock delivers up to 85W to the computer). , while the Apple charger delivers up to 87 W). This solves the problem, but unfortunately robs this dock of one of its key benefits, as USB-C power delivery is a big part of the reason the dock is priced. I can confirm that this is not a "rotten egg" as I have purchased two such docks (office + home) and have solved the issue on both docks with any combination of USB-C cable/power adapter/dock (regardless of connected peripheral devices) persists.
