I recently bought, and returned the next day, a Logitech headset which connected to the audio inputs of my MAC G4. The microphone was apparently dead out of the box. I have had similar quality problems with products from this company before.

I had it for 10 months, used it daily for internet voice chat and a bit of music listening. No big demands. Had clear sound, the mic was fine, the USB convenient. However, although I treated the unit with utmost care, after 10 months the wires in the cable connected to the inline volume controller broke up, and I could hear the sound through the phones only at a specific cable bending angle. Then, after 3 days, the wires totally gave up. I can not get to the wires since the volume unit seems to be welded together. Will try to get RMA.

I went to Staples and found this one and read the features and was impressed and wanted to try as rest that fall in the category are a little pricy! but after i had this product for 4 days i am disappointed at the workman ship, the usb interface (black little rectangle thing) is bulky and i could not wear the phones comfortably as i had lot of ear rubbibg despite the soft earpads, I just did not like this product and i am shipping this back to amazon and am planning on getting SONY MDR-NC6 which i tried at my friends place.

Headphones and mic work well enough. Though I had the same problem as the Dr right out of the box. It tries to adjust the volume to zero. My work around was a tube of Chapstick and a mini wood clamp to hold the up volume control button in. This causes the volume adjustment to stop so I could use the headset. I like it but it's definitely getting returned/exchanged.

This headset really disappointed me. For the first four to five weeks I owned this headset, it suited my needs. However, it soon began to fail; it refused to play back any audio and it recorded unacceptable amounts of static. Despite these problems, it is incredibly expensive for the quality it promises. Logitech has completely ruined this headset.
