Very impressed with this little guy. I needed a solution to add audio to my helmet without wires. I was able to fit this on my helmet with a shorter cable and use my phone to connect...
...it worked like a charm! I could ride, easily, for 8-12 hours at reasonable volume while this little guy drove the larger speakers in my helmet.
I've since used it to connect my home stereo, car stereo, even my ear buds when my phone will be near by, but I don't want the weight, or I'm working in the dusty shed/wood shop.
Been two seasons on this little guy...so they'll definitely do right for you.
