I bought the UClear HD speakers with a 3.5mm plug and bought the SMH10 mount that allows for plugging in ear buds (about $35). I picked up a FiiO amp and plugged it in to the SMH10 and the speakers into the output of the amp. I did reinforce the speaker wire where it attaches to the plug as it felt like a point of failure waiting to happen. This little amp works well enough, especially for the price (about $20.00) has a real some really basic equalizer presets that are easy to change while on the move. I actually use the setting that enhances the treble. All in all it works very well. I do have a concern about moisture/rain getting into the open charging port. If necessary, I can pull it off and stow it while my bucket is on my head because I have it attached to the helmet with outdoor velcro. I am able to get about 3 hours with foam ear plugs in before they start hurting but I'm getting used to them and benefits of a far more comfortable ride and AWESOME music sound is well worth it. 10 minutes at the gas station during a fill up with the ear plugs out and I'm set to go for another 3 hours. This bucket is really comfortable and quiet.
Ride Safe.
