You show another tiny little speaker that produces no bass. In open air it resonates at 280Hz but in a needed enclosure the resonance will be higher at maybe 340Hz like a bongo drum with 4 low frequency audio octaves missing!
You did not say the impedance of your headphones and AliExpress does not say the recommended headphones impedance needed for their no-name-brand preamp. But the old NE5532 dual opamp used has a minimum output load of 600 ohms. If the impedance of your headphones is much less than 600 ohms then they will produce low level sound without any bass.

Hi Klaus!Hi,
Visaton speakers usually are quite good.
For sure size matters. Due to physics the lower cutoff frequency is limited.

Thanks for your contribution!To upgrade the sound, the monitor box will compromise even the best attempts.
I suggest you put your Logitech's and sub-woofer well hidden behind and under.
I use Yamaha's I got for $9 behind my ears on the couch from Value Village (recycling) and a sub-woofer for the same price hidden in a drawer slightly open . driven by a Win 7 tower to watch a 56" Hitachi just past my feet to feel like a big theatre any movie or TV.
In that case (pun intended) you can buy 10 of these stereo bridge amps for floating speakers for $13c with no heat sink required. Only 5VThanks for your contribution!
Please keep in mind that the focus of this project is not building the perfect hifi audio system but just turning a mono monitor into speaker and upgrading, even a bit, its audio quality at the same time.
The fact that the monitor should look original and have internal speakers is important for the sake of this project.
Thanks for helping!In that case (pun intended) you can buy 10 of these stereo bridge amps for floating speakers for $13c with no heat sink required. Only 5V
