> people who use speakerphone and inflict it on people
To be fair, this varies by speakerphone. I use a landline phone with a high quality speakerphone. As far as I've been told, the quality is as good as possible (limited by the line I'm dialing into).
- yes lag, having to deal with delays and jump in at the right time is fatiguing
- audio - auto-muting, inexact codecs, compression artifacts, bad echo cancellation
- small screen, and mismatched eyes
- there is also etiquette.
inadvertent - people who talk too loud or don't understand the lag or don't notice their drop outs
should-know-better - people who use speakerphone and inflict it on people who deal with headsets to give others good sound. or carry their devices moving
