Query: Best Headphones for Under 20 Dollars

These headphones are comfortable, lightweight, durable, and sounds really nice. I'm bought this 7 months ago and they've lasted me without any problems on daily use. I'm buying these again when/if they break. I've seen similar Coby branded ones but they feel so cheap compared to these. Very well worth every penny.
