Sonnet Echo 11 Thunderbolt 4 Dock Review
The Sonnet Echo 11 is a Thunderbolt 4 dock with 11 total ports, 90W host charging, dual 4K@60Hz display support, and a machined aluminum chassis for ~$280.
Sonnet built its reputation on Thunderbolt expansion chassis for professional audio and video studios, and the Echo 11 carries that engineering focus into a general-purpose dock with an unusually rigid, fanless aluminum enclosure that stays silent under sustained load. 90W of host charging is adequate for a 14-inch MacBook Pro or similar ultrabook, though studio users pairing it with power-hungry accessories should budget for a separate charger on heavier days. Versus the Elgato Thunderbolt Dock, that targets streaming setups specifically, worth it for creators over Sonnet's broader studio-equipment focus. Versus the CalDigit TS4, that offers stronger charging wattage, worth it for buyers running higher-power laptops under sustained load.
