For three years I used my iPod and my favorite Sony Sport headphones but I worried about having to turn up the volume to cover up the tractor noise. I recently got both of these and I'm really impressed with the sound and the noise reduction:
- Altec Lansing UHP336 Snugfit In-ear Earphone
- Koss VC20 Volume Control
The total for both was ~$40.
I got the Volume controller for two reasons:
- I lock the iPod and then need to fumble with it to change the volume when a song comes on too loud,
- the wires are never long enough and this adds a good amount to the length between the ipod and headphones.
The in-ear headphones do take some time to get use to but when they're set, they really work well. The music can be low and I can hear details that I never would have with the other headphones. If I want a radio, there are a bunch that work with the iPod too.
