Boasting real-time ear-to-ear translation of 10 different languages, Mars is unique in that it is designed for each person to wear one earbud (as opposed to needing two pairs). Microphones inside the Mars — Line doesn’t specify but we assume they’re bone-conduction mics — feature automatic ambient noise blocking, ensuring that users can take phone calls comfortably, even in loud, busy environments. For translation purposes, supported languages (for now) include: English, Korean, Mandarin, Japanese, Spanish, French, Vietnamese, Thai, and Indonesian.
