Claim 0:
1. An apparatus for enhancing speech sound quality, comprising:
a first wireless earbud, comprising:
a first speaker; and
a first downlink speech process path, coupled to the first speaker, comprising a first packet loss concealment (PLC) processor, arranged operably to perform a first algorithm for reducing effects of packet loss for a mono speech data received through a first receiver of the first wireless earbud to generate a first compensated data; an inverter, arranged operably to generate an inverted speech data or an inverted speech signal based on the first compensated data generated by the first PLC processor, whereby enabling the first speaker to play a first analog signal corresponding to the inverted speech data, or the inverted speech signal; and

a second wireless earbud, comprising:
a second speaker; and
a second downlink speech process path, coupled to the second speaker, comprising a second PLC processor, arranged operably to perform the first algorithm for reducing effects of packet loss for the mono speech data received through a second receiver of the second wireless earbud to generate a second compensated data,

wherein no inverter is disposed on the second downlink speech process path, whereby enabling the second speaker to play a second analog signal corresponding to the second compensated data.
