• UPDATE:

    Active Noise Cancellation (ANC), which reduces background noise is now available on high end TWS earphones, Apple is rumoured to introduce ANC in its next version of AirPods and Huawei has already released one - https://youtu.be/VIxcNDFA02Y?t=193 . The ned gap I posted is for this feature along with sound amplification to be made available to an entry level TWS earphones.
