Why pay $20 more for the T41U over the T41S?

The second USB port. Only worth it if you need to run both a USB headset and a USB Wi-Fi/Bluetooth dongle on the same phone.

T41U vs T46U — which is the better mid-tier?

The T46U is $40 more and adds a 4.3-inch color screen and 16 SIP lines. For executive or front-desk roles, the T46U is the better choice. The T41U is for agents who specifically want dual USB and don't need the bigger screen.

Does the T41U have built-in Wi-Fi?

No — but you can run the WF40 USB Wi-Fi dongle plus a USB headset simultaneously, which single-USB models can't.

Will it work with the EXP43 sidecar?

Yes — the T41U is in the newer T4U generation that supports EXP43 (the EXP40 is legacy-only).

Why the T41U is on the catalog.

The T41U is a narrow upgrade over the T41S: it adds a second USB 2.0 port and otherwise carries the same specs forward. The only reason to choose it over the T41S is the dual USB. If you need to run a wired USB headset (a Yealink UH36 or Jabra Engage) AND a Wi-Fi or Bluetooth dongle (the Yealink WF40 or BT40) on the same phone, the T41U is required. Single-USB phones like the T41S force you to choose one.

Where this happens in real life: hybrid offices where the network drops are scarce and Wi-Fi is the primary connection, but the user is on calls all day and needs a quality wired USB headset for the audio chain. Or, less commonly, hot desks where staff bring their own Bluetooth headset and the BT40 dongle stays plugged in while a different USB device serves the next user.

Where it does not make sense: most desks. If you only ever run one USB device, the T41S saves you $20. For a Wi-Fi-needing desk where you do not care about USB headsets, the T54W gives you built-in Wi-Fi + Bluetooth without needing dongles at all. The T41U occupies a specific dual-USB niche that most buyers do not actually need.
