Great sound, maybe not as loud as I would have liked, but solid range (lows, mids, and highs).The single button on the ear doesn't work properly with all devices though

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

It is a universal fit and fit my helmet to a T. Very comfortable and easy assembly

However, the in-line button works as it should

Didn't work out as I had hoped

They work as they are advertised
