- Receiver count and expansion: Do you need a scalable kit that can add more receivers over time?
- Compatibility: Will attendees use traditional receivers, Auracast-enabled hearing aids, or neckloops? Verify supported devices.
- Audio quality and channels: Do you need stereo sound, multiple channels for different groups, or a language-translation feature?
- Power and portability: Are the units battery-powered or AC-powered? Consider charging strategies for long events.
- Ease of use: How simple is the setup, pairing process, and daily operation for staff?
