Guide: translation earbuds

Here you will find answers to the key questions about translation earbuds: how they work, what works without internet and what to keep in mind in everyday life.

• How do translation earbuds work? The earbuds connect to your smartphone via Bluetooth. The SITranslate app recognises the spoken language and translates it, and the earbuds play the translation directly into your ear.
• Do translation earbuds work without internet? Partly: English also works offline, further languages can be downloaded as offline packs. The rest need an internet connection.
• What does the other person need? Just one earbud: you each wear one and understand each other – one set is enough for two people.
• Earbuds or just a translation app? In both cases, an app does the translating. With translation earbuds, however, you hear the translation directly in your ear, and the other person wears the second earbud.
• Which languages are translated? The SITranslate app lists 144 languages and language variants (as of October 2026). English also works offline, further languages can be downloaded as offline packs, the rest need an internet connection.
• Translation earbuds for travel When travelling, you each wear one earbud in a conversation and the app translates. Plan for internet and battery: English also works offline, further languages can be downloaded as offline packs, the rest need an internet connection.
• With family or a partner in another language You each wear one earbud, the app translates, and you hear the translation directly in your ear.
• Battery and charging: how long do the earbuds last? Up to 6 hours per charge, depending on use and volume. The charging case recharges the earbuds on the go and shows the battery level in percent.
