Comfort and Fit:
These headphones have oval connections that completely wrap around the ear and secure the buds nicely inside the ear canal. This setup takes a bit of getting used to and is a touch cumbersome to put in place, but one secure the headphones don't move, no matter how much you jostle around. This is a huge benefit for active exercise.
The wires are plenty long and don't need an extension. For running the balance is always a wire long enough to prevent yanking, but not so long as to snag your hands while you run or annoyingly flop around.These headphones strike a balance here by providing a long cord secured by clip for your shirt. The wire is fed through the clip so the amount of cord that hangs loose can be adjusted.This solution works fairly well, but does have drawbacks. First, the clip is a bit complex to open and close. The instructions on operation are very sparse, and if you aren't careful you can break the clip while trying to force it open.Once you get the hang of it, it's not too bad, but be careful.Second, this solution requires you run with a shirt (no issue for the females), but if you run shirtless you are stuck clipping to the shorts, which is tough.
Sound quality:Because of the snug fit, the headphones do an excellent job of blocking out outside noise, which enables you to hear nuances in your music you may otherwise not hear. That was the first thing I noticed when I switched to these headphones. You don't get quite the depth you'd get with a premium headset from SkullCandy, but for exercise at around $15 I had no complaints. They are far better sound-wise than the quality you get from the standard headphones you get from the manufacturer of an MP3 player or Iphone, for example.I found no static at all, with all sounds crystal clear.
Styling:Style is individual, but I find these look rather decent. They do make your appearance a bit funky if you have to run with a hat in cold weather, but their heavy-duty design indicates you are serious about your running.
Durability:I've used these now many times a week on long runs through all weather with no issues. Time will tell how they survive long-term, but so far no issues.
Overall:These aren't perfect, but if you value quality sound from a secure headphone for exercise without breaking the bank, these Sony headphones are an excellent choice.
