Comfort zone
We appreciated the overall design and ergonomics of the M205. The bud, which comes with two foam covers, should fit snuggly in most ears. Another plus is that the in-line mike is set in just the right place on the cord. It sits near enough to your mouth that you don't have to worry about pulling it closer for people to hear you better.
As for the headset's features, this model does have an in-line volume control and a Mute button. Unfortunately, it's missing an answer/end button, which the similarly priced supports.
High quality
We had no complaints about the M205 in the performance department. As with the M206, callers sounded loud and clear, and they said they didn't have any trouble hearing us.
Overall, the M205 is a solid headset, though we wish it had an answer/end button. Although the headset lists for $39.95, you should be able to find it for closer to $20. At that price, it's a relative bargain.
