Please could you advise. I have Senneiser Momentum 2. How can I use these wireless Senneisers to listen to audio from my Linn Kairn preamp. Thank you.

So obvious. I feel so STUPID. Although my Naim amp does not have an on off switch, I can do it via the mainsplug switch. Once again many thanks for your HELP. It is most appreciated

Thank you for your quick and helpful response. Unfortunately, the audio comes out BOTH from my speakers AND the headphones. Any further advice would be gratefully appreciated. .

I have the following equipment - Amp Naim NAP 90, LINN KAIRN PRE AMP (& Cambridge audio streamer & Arcam CD player) but none have headphone socket. Today I bought a Headphone AMP/DAC- Epiphany AcousticsEHP-02Di hopeing this may be the solution but I don't know how to connect so that I can use...
