If you are singers, they need to open their mouths to make ear molds.

If it is only for listen to music, no need to open mouth to make ear molds. They closed their mouths, so won’t miss the sound.

If you are ordinary audiophiles, closed your mouths to make the ear molds. In this way, the ear canal will be in a normal state and will not be compressed and deformed. Soundproof will be better after make out.

Singers open their mouths because they sing on stage. They always need to open their mouths to sing. Opening their mouths can narrow the ear canal. The advantage of making ear mold with your mouth open is that you won't feel squeezed when you sing. The disadvantage is that it will miss the sound, but it doesn't matter, the stage singing has bass compensation.

Tuning Trend

4PRO tuning enhances low frequency quality compared to 3PRO

In the same 020 mode, 4PRO can bring more abundant low-frequency energy, weaken some harsh frequencies, and have more accurate sound details. The overall sound field has been expanded, which greatly increases the sound density and makes the music expression more full.
