Rating : - Not bad, but I'm still looking for ideal.
Having used the Sennheiser PMX70 Sport Line Stereo Neckband Headphones for a few years, I was looking for something that would offer the same sound quality, but also work when wearing a hat or headband in the colder months. These looked to be the most logical choice.

Unfortunately, they seem to only fit one type of ear since they are more or less non-adjustable (they do have one adjustment, but it doesn't seem to be the right kind). Unless I'm standing still and actively pressing them in to my ear, they are not snug enough in my ear canal to offer the sound quality they're capable of (I assume they use the same driver and construction as they PMX70).

On the plus side, they are pretty comfortable and I'm certain they'll prove rugged. I've worn the PMX through rain, snow, basically every bit of weather you probably shouldn't wear them in. I've had to use some super glue to repair the headphone plug (the rubber pieces came apart), but they still sound the same as the day I bought them.

If these do work with your ears, good for you. You've got a product worth five stars.
