These earphones are good quality, and fairly comfortable, however, the sound quality wasn't that good. Also, for some reason, when I use these with a USB audio adapter ($1 off ****), the sound quality is bad. First, I thought it was the USB audio adapter, however when I plugged in a cheap ($10) headphone, it sounded great! I was surprised, happy about the USB audio, but disappointed with the earphones. It may be some impedance mismatch, but compared to the $10 headphone (with volume control) I expected more.
