Used them about a month and the buttons stopped working, as well as the wires shorting out often

The sound from the 2" diameter Chips® was pretty good, depending on the song and genre, and the controllers worked well, just as indicated in the instructions

They sent me a new wire and they have worked well since

Microphone works great too

For the rest of the day, it was very intermittent, but mostly not working, which was a huge disappointment.

These work perfectly in my ski helmet, volume has good dynamic range, very easy to be too loud

Very nice little gadget, fit in my helmet nicely and all the buttons work great

I use it for skiing and few electronics work well below 15 F, which was why I bought these wired ones

It became VERY sensitive to how it was positioned to get any sound at all and sounded terrible when it did work.
