The flow of electrons in a copper wire is much slower than a wireless or fiber optic signal, so over longer distances, theoretically it could be lower latency.

The flow of electrons in a copper wire is much slower than a wireless or fiber optic signal, so over longer distances, theoretically it could be lower latency. I suppose the challenge is in building a fast enough encoder/decoder and dealing with interference
- SECProto 4y ago> The flow of electrons in a copper wire is much slower than a wireless or fiber optic signal, so over longer distances, theoretically it could be lower latency "flow of electrons in a copper wire" has little to do with the speed of a signal transmitted via electrons in a copper wire - what we care about here is propogation delay[1]. Assuming that the speed is about c in air (a bit less but whatever) and at least 0.6c in copper, and assuming a minimum threshold of say 1ms of delay being noticeable to an audiophile, then you would need a headphone cable about 450km in length to noticed the difference.
