This headset is comfortable to wear, and fits over the ears well, so that any noise around me in my surroundings is reduced or eliminated as much as possible. This headset meets that requirement. However, it would probably work better if it had a design where it cups around your ears by having the "Ear Drivers" recessed and then have padded material that would surround each "Ear Driver" or speaker.
Good clear microphone. Yes, this definitely has that. People said I am crystal clear.
A wired headset should have a longer cord. This device fails in that area. Cord length for the H540 is too short. Logitech, what were you thinking with this short cord?
The headset cord is too thick, compared to other headsets, and this presents a problem. Even the slightest movement, if you move the cord around on your desk as you are talking (which I can't avoid, since I am always moving around when I am on the phone) this produces noise that is picked up in the headset. You will hear the cord thumping and moving around in the earpieces, as well as the mic picks up the cord noise thumping and moving around, this is very distracting.
The cord should be insulated better so it doesn't produce noise in the actual headset. I would suspect if Logitech redesigned this headset with a thinner cord this probably would resolve most of the issue.
The Volume and Mute buttons should not be on the headset, and should be put on the cord with controls for these functions. When you push the Volume/Mute buttons on the H540 headset, it causes so much noise in both the earpieces as well as it's picked up by the mic.
Also, the red Mute Indicator on the cord is another design failure. Even if Logitech doesn't move the Volume/Mute controls on the cord, the Mute indicator is too close to the headset, and should be placed further away from the headset so that the light is easier to see. It's distracting to have to look down against my shirt, where the indicator light is, to see if I have muted/unmuted the headset. It would be much easier if I could glance down on my desk, to see the Mute Indicator.
This Logitech could have been a good headset, if it didn't have all these flaws. I returned this headset a couple days later, and then after doing some research I found the Microsoft LX-6000 headset on Best Buy's website. Microsoft got everything right with their headset:
1. The Microsoft LX-6000 cord is definitely long enough
2. The cord is thinner and does not produce noise in the headset when it's moved around.
3. Mute and Volume Controls are on the wire, and not on the headset, and are far enough away from the headset where these controls are easily accessible and easy to see when the Mute button is activated
If you're looking for a better headset, I'd recommend the Microsoft LX-6000. If you want to upgrade to a better Logitech wireless headset, I'd also recommend the Logitech H800 which also has Bluetooth.
Logitech has made many good headsets, but this H540 is a disappointment, it has too many design failures. At the time of this review, the H540 is $50 USD. For the amount of money that Logitech is asking for this, it should be much better.
