Solve the wimpy Savage problem
Bought a Savage open-face helmet last year as addition to full-face Shoei with SENA 10U installed.
Savage worked OK for slow riding on naked bike, but wind noise exceeded speaker volume at 50+MPH. Contacted SENA for support, but no simple solution - helmet fit is good, no optional side pads available, no speaker upgrades.
So I solved the problem with hack: removed the SENA speakers, clipped the original speaker wires to re-use proprietary connectors, determined wiring polarity and proper grounding, and soldered in a stereo 3.5mm headphone socket for use with in-ear monitors (IEM).
I'm using special high impedance IEMs with 260 Ohms each side. High impedance reduces load on the SENA amplifier for safe operation.
Result is excellent sound, great noise isolation, easy conversations using the Savage's built-in brow microphone. Modification recommended if your Savage sound sucks!

What are the 2 plugs that are after the solder joint for the headphone socket, and do you have a brand and model of the iem that you used?

The 2 small wire-to-wire connector sets shown in upper right photo are the original SENA speaker connectors. Each connector has a two-wire harness (+ and -) and those wires were joined with pigtail from stereo (TRS) 3.5mm socket.

Ok ok, I haven’t gotten into mine yet so I didn’t know if that was something you did. No chance you can give the brand and model of the iem’s you used? I’ve done quite a bit of searching and can’t find anything with such high impedance. The highest I found was 150ohms and it does not say if that is together or separate. Thank you
