I got a sound whenever the device starts and stops sending audio. The sound happens just before audio starts, and shortly after audio stops. It's the sorta sound you'd get when plugging headphones into an old school cassette Walkman while it was running. Here're all the noises I hear from turning it on to turning it off:
- ((At this point, the 5K is off))
- ((Hold the power button for 3 seconds))
- Two pops (that Walkman noise)
- "Click" sound effect (power on)
- "Whip" sound effect (bluetooth connected)
- A momentary high pitched sound (maybe one or two ms in duration)
- ((Hit Play on my Bluetooth connected phone))
- Two pops (the Walkman noise)
- ((4 seconds later))
- A momentary high pitched sound (maybe one or two ms in duration)
- ((Hold the power button for 3 seconds))
- Two pops (that Walkman noise)
- "Click" sound effect
- A momentary high pitched sound
- ((The device is off now))
Hmm...now that I try this using some Earpods I had laying around, I don't hear any of the clicks or pops.
I grabbed all of the audio stuff I had within reach and the results are pretty revealing:
I get the noises above with the following:
5K
-> 3.5mm connection
-> This cable: https://www.aliexpress.com/item/32954926911.html
-> TRN V80s
And I don't get the pops with any of the following:
5K
-> 3.5mm connection
-> Apple Earpods
5K
-> 3.5mm connection
-> Bose Quiet Comfort QC35
5K
-> 3.5mm connection
-> This cable: https://www.aliexpress.com/item/33004681759.html
-> TRN V80s
Although I'm wondering what's make it transmit these sounds, I guess I'll make this 16 core cable my new backup and start using the TRN cable. Any idea why a cable would cause these sounds? I'm not an electrical engineer, but am now super interested in what this phenomenon is.
