Comparison

The platform or rented receivers

Either way, the interpreter needs quiet and sound isolation. The difference is what happens on the listeners' side and what it costs you

What you pay now

Receiver rental is more than one line in the budget

Usually only the cost of the devices makes it into the estimate. The rest comes up along the way

Receiver rental

Charged per unit, per day. Three hundred people means three hundred units, and the price grows with the length of the event
Deposit

Tied up for the duration of the event and returned after the count. Lost and damaged units are deducted
Handout desk

Staff to hand out and collect receivers, plus a line at the entrance at the worst possible moment
Logistics

Delivery to the venue and back, and for another city also packing, insurance and travel time
The count afterwards

Checking numbers, charging, maintenance. Work nobody puts in the budget, but somebody does
Remote attendees

A receiver only works in the room. The online part needs a separate solution and a separate budget

Devices

The platform The listener's own phone and headphones

Receiver rental A receiver and headset for every listener

Entry

The platform Scan a QR code at the entrance, pick a language in the browser

Receiver rental A line at the handout desk, ID or a deposit

Scaling

The platform More people, same price per event

Receiver rental More people, more devices, more money

Another city

The platform Nothing to ship

Receiver rental Equipment is shipped, insured and returned

Remote attendees

The platform They hear the same channels as the room

Receiver rental A separate setup for the online part

After the event

The platform Per-language recordings are ready, nothing to collect

Receiver rental Collecting, counting, charging, writing off losses

An honest boundary: the platform replaces the listeners' receivers, not the event's entire technical setup

The interpreter still needs quiet and sound isolation: a booth in the room, or a quiet space with a headset when working remotely
Sound reinforcement in the room stays with your audio contractor
If the room has no internet and it can't be arranged, equipment remains the only option
