Perfect, especially for so cheap!
The way this headset is made is just brilliant. Even during long typing sessions, the stethoscope-style design makes it easy to get a good fit. The mono audio output makes sound that is clear and crisp, so that every word is heard correctly. As a legal transcriptionist, I have to deal with a lot of private information. Because of this and the fact that I like to work out in public from time to time, I really needed a headset that doesn't leak any audio out while I'm wearing them, and this does just that. It gives me peace of mind while I work and is perfectly comfortable for long wear.
