Transparency Mode is a feature that allows you to hear the noises around you without removing your earphones.
The microphones, which are usually used to pick up your voice for a phone call are repurposed to ensure you never miss a train announcement or continue a conversation without interrupting your music.
To enable or disable Transparency Mode, simply triple-tap either earbud or navigate to the Hub page of the Melomania app. When it is activated, you'll hear the phrase "Transparency On". When you wish to re-immerse yourself in your Music, simply triple-tap on your earphones again. You'll hear "Transparency Off" once it has been disabled.
You can change the level of Transparency in the Melomania App by sliding the case to suit your needs.
