Hi, All:

I just got a Lightspeed Delta Zulu, and per the instructions set it up in a quiet place. But when I turned it on, I could hear a soft, persistent hiss. This is in contrast to my AirPods, that, when make things absolutely positively silent.

I asked Lightspeed tech support, and they were ... just a tad ambiguous as to whether this was normal or not - they said try it in the airplane and see how I liked it.

That was a discouraging answer, so I am turning to the experts here. If you have an LS DZ and turn it on in a quiet place, do you hear anything at all?

Thanks for any info,
