Review on Cubilux USB C Headphone Adapter With Built-In DAC &Amp by Silvia Morales

I have found that this adapter for my HT C U11 phone (I love it) will fit one of my headsets but not the other. Also, the sound of my voice (I recorded a message on my landline phone to hear my voice) has high-frequency distortion. As a result, my words are understandable but not harsh. If I were to frequently use a headset to communicate with customers, this would not be acceptable. Not sure if another brand adapter would be better. I understand that the USB-C connector puts digital, input and output. So this little adapter has a big codec function to convert any direction between digital and analog. It's pretty amazing to me that these little guys of any brand work at all.
