And I will reiterate that that article, and anything to do with impedance and sensitivity is only relevant to analogue headsets that (for this discussion) plug into a computer or phone's headphone jack(s). Any audio played by a computer will have been digitised. It will then have to be fed to a digital to analogue converter (DAC), which feeds an analogue amplifier. The amplifier will drive the speakers in the headset. For analogue (headphone jack) headsets, the DAC and amplifier are in the computer/phone and the headset only contains the speakers. For USB headsets the DAC, amplifier and speakers are all in the headset. Because a USB headset contains both the amplifier and speaker, you don't have to worry about matching the speakers' impedance and sensitivity to the amplifier. The manufacturer will have done this as part of the design. This is an advantage of USB headsets. Given the same digitised audio sample, the headset will sound the same no matter what device you've plugged it into and is feeding that audio because it's going through the same DAC, amplifier and speakers. With an analogue headset, the same audio sample will go through a different DAC and amplifier in each device before going to the speakers, so it could sound different on each device. Once you've found a USB headset that you like, you can be sure it will sound the same, given the same digital audio source, no matter what you've plugged it into that's providing that source. -- Scott --- Post to this mailing list [email protected] Unsubscribe from this mailing list https://gtalug.org/mailman/listinfo/talk
