Using headphones vs. loudspeaker

With headphones:

• Barge-in works reliably — you can interrupt the tutor at any time by speaking
• Cleaner audio input — the microphone only picks up your voice, not the tutor’s speech
• Better focus — you hear the tutor clearly without background noise interference
• Private learning — conversations are between you and your tutor

Any headphones work: wired earbuds, over-ear headphones, or Bluetooth.

Loudspeaker mode works, but with limitations:

• No barge-in — the microphone picks up the tutor’s voice, so you need to wait for the tutor to finish speaking before you respond
• Echo risk — in quiet rooms, the device may hear its own audio and get confused

Loudspeaker is fine for casual sessions, but headphones are strongly recommended for the best learning experience.
