Headsets

Superior headsets produce superior recordings, so what makes one headset better than another?

Sound Isolation

Does the headset provide circumaural earcups that fully cover students' ears and block sound?

USB Chipset Quality

Many low-end USB audio controllers suffer from clock drift and require corrective measures in software.

Side-Tone

Does the headset have side-tone, i.e., the ability for students to hear themselves while they speak?

Microphone-Mute Button

Does the headset have a physical mute button that students can trigger by accident?

FAQs

Why should I use DiLL? My students already speak in class.

DiLL helps teachers maximize students' speaking time in class by providing a controlled environment that allows all students in the classroom to speak simultaneously without distracting each other.

If the whole class is speaking at the same time, won't students record over each other?

For classroom use, a headset with circumaural headphones and a noise-cancelling microphone will capture only the speaker's voice while also allowing the student to listen -- distraction free.

Will DiLL work wirelessly?

Yes! You can turn any classroom space into a full-featured language lab using only DiLL, Macs, and 802.11n/ac WiFi, without sacrificing either voice quality or voice latency.

Is DiLL Mac only?

DiLL is currently only compatible with Macs. In the short-term, we'll be releasing an iOS app for iPads, iPods, and iPhones.
