Sleepbud Electronic Hum Complaint
I bought a pair of sleepbuds about a month ago, but returned them for a different pair since they emitted a high pitched sound during use. I heard this high pitch sound mostly in the left ear.
I noticed that when they are activated/play the selected sound, the sleepbuds emit a hum. This low level sound, sounds like a high piched frequency, or similar to what a speaker would sound like when it has too much power running to the speaker, if I pause the audio the high pitch frequency stops. This electronic sound can be heard over each of the select recordings and is too distracting to for sleep.
Since I have tried two pair, I am wondering why the buds emmit an elecronic hum when the play button is pressed? Is this a normal function for the bud? Should the sleepbud when playing sounds, be completely clear of any electronic artifact? If this is just the design of the bud, I will have to return them as they will not be the best fit for me.
Does anyone else hear this feedback in the bud?
Yes, I have updpated the case and the sleep buds.
