SonusQuest vs 背书帮

SonusQuest: Turn your phone into a real-time in-ear monitor — it captures the sound around you, removes noise, boosts your voice, and plays it back through your earphones so you can hear yourself while live streaming. It can be used to practice pronunciation, reading aloud, singing, aiding memorization, DAF (Delayed Auditory Feedback) therapy for stuttering, and more. Some users with hearing loss use it as a hearing aid; we suggest such users treat this app as an introduction to hearing aids rather than a replacement for one. 1. Supports both wired earphones and Bluetooth earphones 2. Supports the phone's built-in microphone, wired earphone microphones, and lavalier (clip-on) microphones 3.
