I had an H530 which I used daily for about a year, then the mic quit working. (Short/intermittent). I bought the H540 to replace it & now have the same problem after only about 4 months. The quality in the mic is very poor. Wire breaks way too easy. Will be sending this back to Logitech.

Comparing this headset 540 vs the 340, and found the build quality of the 540 was significantly better. The USB plug doesn't look like it will fall apart anytime soon. I found that frustrating about the 340. Also more quick and easy features, such as adjusting volume and turning mic on or off.

Cable is too stiff and cannot be used for long periods. The headphones sound clarity is OK however it could be better.

I am a medical transcriptionist. I bought this based on the recommendation of the lesser priced headset and these were offered as an upgrade. They are uncomfortable, gave me a headache and the earcup rubbed my ears raw. The sound quality is not any better than the $10.00 earphones I had been using.

Excellent product , good quality sound and both spoken and received sound quality – Well worth the money , I have even bought a new one as a spare

This is a good headset for the price. I you want all the extras you are going to have to pay more.

The Logitech H540 will fail (short out) at the red mute indicator LED mounted inline on the USB cable. First it looks as if you might have not muted the microphone because you will find the red LED is off. Then you might notice that red LED starts to flicker.

Looks nice until you touch it Stereo sound quality is reasonable

Design flaw in the SUPER STIFF cable with mounted mute indicator LED will cause the headset to short out the USB connection and eventually the internal connection at the mute LED will fail causing the H540 to stop functioning.

Positives: Works as expected, well made, decent price Negatives: Sits heavy on the head, I didn't feel comfortable using it compare to Platonic headsets. Sound is not that great either, must be smaller drivers in unit..

sound is good when used with Skype for Business, but mic is nowhere close to the quality of my Plantronics Savi 7xxx. however the most disappointing part is the my Avaya OneX softphone wont recognize it.

I purchased this headset for use when working remotely as facilitate a lot of conference calls using VOIP technology. I need a wired version when traveling so that I do not have to worry about charging the headset. This particular headset did not perform well. The sound quality was poor.
