Subject: First impression - Sennheiser PMX70
I bought the Sennheisers on eBay for $35, including shipping.
The PMX70s definitely sound better. More bass response than the Koss P-9s, with much crisper sound quality.
So what is "crisp" sound quality? Perhaps this example will help quantify it. After my run outside, I was cooling down on the treadmill, walking with my head down, when "Pros and Cons of Hitch-Hiking" came on. About 1:40 into the song, there's the sound of a car driving by, going from right to left. I jerked my head back, trying to see WTF was driving in my basement.
I've heard that song many times before and never had that reaction.
Fit is probably the biggest variable from person to person. When I first tried them on, the PMX70s were somewhat uncomfortable, too tight. The earpieces press into my ears, placing all of the pressure there. In contrast, the Koss band makes light contact against my head, taking up some of the pressure.
After bending them the Sennheisers neckband a little, I went running for about 50 minutes. They were fine, they did not bother me at all.
After two runs with them, I'm quite happy. I'll see if they hold up.
