    <p>I have a Sony CECHYA-0076 with a TPLink UB400 Bluetooth. Finally
      I could connect everything  to use as a sink/source device. Tried
      recording to Audacity, creating a module-jack to put inside it
      and, the simpliest way to test it, creating a loopback module to
      "hear what I talk" inmediatly.</p>
    <p>I read everywhere that the HSP/HFP is not a good sound... but
      every bluetooth microphone using this profile sounds as terrible
      as this? I tried everything (*) to improve it, but with no
      success. Please, hear attached file or click on
      <a class="moz-txt-link-freetext" href="https://sndup.net/3smb">https://sndup.net/3smb</a></p>
    <p>So, if this is normal audio quality for HSP/HFP... <b>who was
        the person that allowed this profile to be available?</b> It's
      completely unacceptable.</p>
    <p>Here is my question in StackExchange:
<a class="moz-txt-link-freetext" href="https://unix.stackexchange.com/questions/590641/how-to-improve-mic-quality-from-a-bluetooth-headset">https://unix.stackexchange.com/questions/590641/how-to-improve-mic-quality-from-a-bluetooth-headset</a>,
      but I think that it has no possible answer. I mean, there is no
      way to improve what was created like that.</p>
    <p>Sincerely, I don't understand.<br>
