Are all the Huawei headset holes supposed to give sound??

[Android Central Question]

The thing is my y7 came with some headset. Well, as you ill know this type of headset has like 2 holes by which the sound gets out. My problem is that, if theres 4 in total, they are working just 2 of the. This is not a problem at once, I can still listen to music, but id like to know if they are broken, as they are new.
When I put my headset really deep, well put, I dont hear really loud the music, as both holes which function are obstructed by my ear.
Hope some one understands me.
Thanks for your time

You can see 2 photos. The round speakers do function, but the other one dont. The other pic its other tiny hole whom functionality I un know.

The other openings are probably bass reflex vents: https://en.wikipedia.org/wiki/Bass_reflex
