TUNE-FLEX: Does the JBL Headphones app give me any indications when I choose different Ear Tips mode?

JBL Tune Flex is packed with two types of ear tips. These are called “Open Ear Tips” and “Sealing Ear Tips”.
When you click the Ear Tips mode, you will hear a tone to remind you of the different sound modes (Voice prompts not ready yet).

TUNE-FLEX: What happens if I do not perform the “Ear Tip Sound Settings” check using the relevant ear tip?

If you do not perform the "Ear Tip Sound" setting after changing the ear tips, i.e., using the “Open Ear Tips” for “Sealing Ear Tip” mode, the sound will not be as natural as with “Sealing Ear Tips”, and vice versa.
