I've had my pair for at least a year and a half now, I believe, and they are still perfect. A couple of months ago, I stepped on the things, and they fell apart, but I was able to snap the necessary piece back on and they continued to work perfectly! One thing that is annoying if you have longer hair is that it will rip stray hairs out now and then, as everyone mentions. The metal bands catch hairs sometimes. I never really noticed a big deal with the "firm" and "light settings. It's just a minor adjustment, mine has been on firm forever. I workout with these and they stay on perfectly. Treadmill walks, heavy squats and deadlifts, I don't know about running though, but I imagine they'd be okay. The black cushions for the ear pieces have only fallen off a few times since I've had the headphones and still stay on snug till this day. The sound quality is the best you can get for this price range, and is slightly/moderately bass heavy. On bands that already have amped bass, it may be annoying. It all depends on the production of the album, though. The majority of music will probably sound fine. Rock/metal will be fantastic most of the time. There are a couple albums every now and then that will be way too bass heavy, but it's rare. Change the grip setting to light to loosen up the bass tone a tiny bit. Also any idiots (like me!) who it takes over 2 minutes to figure out how to adjust the things, you push the black rectangular pieces together to open them up, place them on the head, then pull apart to tighten. Be careful tightening as this is where it can grab your hairs. As stated, they stay on your head pretty great. Great, long-lasting headphones, very highly reccommended!!
