No audio jack on the Trophy SE. Personally I use the Sena SMH10 Bluetooth stereo headset attached to my full face helmet to get my music. My molder ear buds are attached to the Sena and I get XM radio and iPod all with the Bluetooth capabilities. Works great for getting music piped into my helmet but can also make/answer phone calls and have a passenger intercom all with no wires. As a former BMW RT and GT owner and audiophile I love the Bluetooth on the Trophy.
