Does it work with bone conductors?

compare all specs before buying

It keeps asking me for the code and i can't find it. Is there a genetic code?

There is no code needed for pairing. May i know which device you are tryting to pair with the Relay please?

When used with two headsets, can each set of ear buds control volume independent of the other?

If you want to adjust the volume independently, please adjust the volume on the headphones.

No problem with connection. Works as advertised

Bought it for a recent long airplane ride from Dubai to Canada. Was Flying on ITA Airways. Didn't need to use because ITA allows direct bluetooth connection, but I tested it on my laptop and it worked as stated.Only problem is trying to remember the directions to connect/pair since I don't use it very often.
